All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.
In the related art, uniform production of the chartlet style can be realized through a generator of a game engine, however, the generator cannot enable all objects in the whole chartlet to have the same effect completely, and for effect difference among the objects, extra difference elimination is needed, so that production efficiency of the stylized chartlet is low, and even game development progress is seriously influenced.
To solve the problems mentioned in the background, according to an aspect of the embodiments of the present application, an embodiment of a method for making a chartlet is provided.
Alternatively, in the embodiment of the present application, the above-described map making method may be applied to a hardware environment formed by the terminal 101 and the server 103 as shown in fig. 1. As shown in fig. 1, a server 103 is connected to a terminal 101 through a network, which may be used to provide services (such as charting, etc.) for the terminal or a client installed on the terminal, and a database 105 may be provided on the server or separately from the server, and may be used to provide data storage services for the server 103, and the network includes but is not limited to: wide area network, metropolitan area network, or local area network, and the terminal 101 includes but is not limited to a PC, a cell phone, a tablet computer, and the like.
In the embodiment of the present application, a method for making a map may be executed by the server 103, or may be executed by both the server 103 and the terminal 101, as shown in fig. 2, the method may include the following steps:
step S202, determining a target object to be subjected to chartlet making, and baking a first chartlet of the target object, wherein the first chartlet is used for recording the inherent color information of the target object;
step S204, adding environment shielding light and concave-convex information to the first map to obtain a second map;
step S206, adding texture effect and color blocking effect on the second map to add texture detail and color detail on the basis of the second map to obtain a third map;
step S208, adding a light and shadow effect to the third map to obtain a fourth map under the condition that the detail feature degree of the third map reaches a first target threshold;
and step S210, synthesizing based on the first map, the second map, the third map and the fourth map to obtain a base color map and a roughness map of the target object, deriving the base color map and the roughness map, inputting the base color map and the roughness map into a preset color blocking model, and obtaining the hand-drawn wind map of the target object output by the preset color blocking model.
Through the steps S202 to S210, the production process of the map is optimized, particularly the production process of the hand-drawn wind map is optimized, the production efficiency of the hand-drawn wind map is improved, the color blocking effect is further enhanced through the preset color blocking model, and the effect difference of objects in the same environment is reduced.
In step S202, the target object is an object displayed in the game, such as a character, a building, a flower, a mountain stream, or the like. Baking means that the illumination and darkness information of the object is stored in the texture, illumination calculation is not performed when the object is drawn in real time, and the illumination texture generated in advance is used for representing various effects. The baking technology saves illumination calculation, and can improve the drawing speed. The first map is used to record the inherent color information of the target object, that is, the first map may be the inherent color map of the target object. The solid color mapping is the sum of color effects of objects appearing under the record of white sunlight, and the solid color mapping is baked according to the following steps:
step 1, adopting a uniform white light source to irradiate the target object, and capturing an image of the target object through a virtual camera;
and 2, removing the shadow in the image to obtain the solid color mapping.
In step S204, adding the ambient light blocking light and the concave-convex information to the first map to obtain a second map specifically includes the following steps:
step 1, adding environmental shielding light on the basis of the first map to obtain a first middle map, specifically: baking out an ambient light shielding map of the target object; placing the ambient light shielding map in a primary color channel of the first newly-built map layer, and mixing the colors of corresponding pixels of the ambient light shielding map and the first map in the primary color channel of the first newly-built map layer, wherein the color of the pixel on the first map is used as a primary color, the color of the pixel on the ambient light shielding map is used as a mixed color, the primary color and the mixed color are mixed to obtain a result color, and the primary color channel is a rendering channel in the map making tool; and storing the result color obtained by mixing each pixel in the first newly-built layer to obtain a first intermediate map.
In this embodiment of the application, a Map may be manufactured based on a Map manufacturing tool such as a Substance Painter, where a base color channel is a rendering channel in the Map manufacturing tool, and an Ambient light mask is added on the basis of a first Map to obtain a first middle Map, that is, a first reconstruction Map layer is created, and an Occlusion Map (Occlusion Map) and an Ambient light mask Map (Ambient light mask Map) baked by a target object are placed in a base color channel (base color) of the first reconstruction Map layer, and the Ambient light mask Map and the first Map (fixed color Map) are mixed in the base color channel of the first reconstruction Map layer, for example, a positive plate is folded to obtain the first middle Map. The ambient light mask map is used to draw the effect of blocking ambient diffuse reflected light when an object intersects or approaches the object, mainly by improving shadows to achieve better image details. After the model is made, the ambient light shielding chartlet is not directly pasted on the material ball, but solid colors are drawn, and if the ambient light shielding chartlet is placed on the solid color material in a positive film bottom-on-bottom mode, the light and shade of an object can be more real. The positive film overlay is a mixed mode in computer graphic image software such as Adobe Photoshop, exists in a dimming mode group of a color mixed mode, a channel mixed mode and an image layer mixed mode, and is a dimming mode with higher use frequency for users. The positive pile-up is to compound the primary colors with the mixed colors, the result color is always darker color, any color is compounded with black to produce black, any color is compounded with white to keep unchanged, and when drawing with colors other than black or white, the continuous stroke drawn by the drawing tool produces gradually darker color. In this step, the placing of the ambient light masking map on the primary color channel of the first newly created layer actually uses the ambient light masking map as the fixed color of the first newly created layer, and then the fixed color of the first map and the fixed color of the first newly created layer are subjected to positive film bottoming to obtain the first intermediate map.
In the embodiment of the present application, the Curvature Map (Curvature Map) is a texture of the convexity/concavity of the storage grid, and can be used to cover places where more wear occurs on the surface or where scattering of the sub-surface may occur (convex), where more dirt may accumulate (concave), to check the continuity of the surface, and the like. The curvature map allows extraction and storage of relief information. Black values represent concave areas, white values represent convex areas, and grey values represent neutral/flat areas. And the step of obtaining the second intermediate mapping is that a second newly-built layer is created, the curvature mapping of the target object is placed on a primary color channel of the second newly-built layer, the rendering mode of the primary color channel is selected as superposition, and the curvature mapping and the first intermediate mapping are subjected to primary color superposition in the primary color channel of the second newly-built layer to obtain a second intermediate mapping.
Step 3, roughness screening is carried out on the second middle map by utilizing the reversed phase information of the environment shielding light to obtain a third middle map, specifically: inverting the ambient light shielding map to obtain a first inverted map; and placing the first reverse mapping on a roughness channel of the third newly-built layer to perform roughness screening on the second middle mapping to obtain a third middle mapping.
In the embodiment of the application, the roughness channel is a rendering channel of a layer in a mapping tool. And the step of obtaining the third intermediate mapping is to create a third newly-built layer, perform inverse processing on the original shielding mapping and the original ambient light shielding mapping to obtain a first inverse mapping, place the first inverse mapping on a roughness channel of the third newly-built layer, select and screen a rendering mode, and perform roughness screening on the first inverse mapping and the second intermediate mapping in the roughness channel of the third newly-built layer to obtain a third intermediate mapping.
Step 4, utilizing the inverse information of the concave-convex texture to carry out roughness screening or superposition on the third middle map to obtain a second map, specifically: under the condition that the roughness of the target object is in a first range, inverting the curvature mapping to obtain a second inverted mapping, and placing the second inverted mapping on a roughness channel of a fourth newly-built mapping layer to perform roughness screening on a third middle mapping to obtain a second mapping; or, under the condition that the roughness of the target object is in the second range, inverting the curvature map to obtain a second inverted map, and placing the second inverted map on a roughness channel of a fourth newly-built map layer to perform roughness superposition with the third middle map to obtain a second map.
In the embodiment of the application, the step of obtaining the second map is to create a fourth newly created layer, perform inverse processing on the original curvature map to obtain a second inverse map, place the second inverse map on a roughness channel of the fourth newly created layer, select and screen or superimpose a rendering mode, and screen or superimpose the second inverse map and the third middle map in the roughness channel of the fourth newly created layer to obtain the second map. Specifically, the selection is screening or superposition, and may be selected according to the effect, specifically: if the roughness of the object (target object) as a whole is off-white, it can be selected from screens such as stone, wood; if the roughness of the whole object is dark and gray black, superposition, such as metal, can be used, and the judgment is mainly carried out according to the roughness of the object in the actual scene. The specific division of the first range and the second range can be set according to actual conditions.
In step S206, adding a texture effect and a color blocking effect on the second map to add texture details and color details on the basis of the second map, and obtaining a third map includes:
step 1, creating a first filling layer of a second mapping, and determining the basic color and the roughness of the first filling layer to add textures on the surface of the second mapping;
and 3, under the condition that the detail feature degree of the surface detail added for the second map by the third map does not reach a first target threshold value, continuously creating a new first filling map layer, adding texture and color blocking effects to the new first filling map layer, and taking the new first filling map layer as another third map layer to continuously add the surface detail for the second map, and storing all the third maps until the detail feature degree of the surface detail added for the second map reaches the first target threshold value.
In the embodiment of the application, details on the surface of the second map can be processed to have the effect of colored block hand-drawing by adding the mask, and a filling map layer of the second map needs to be newly built by adding the mask. After the mask is added, the parameters of the first mask can be adjusted by an edge Blur filter (blu Slope). And a filter directional Blur (Blur Direction) can be added on the basis of the first mask, parameters of the first mask are adjusted according to a Blur effect, a sharpening filter (sharp) is added finally, the contrast is enhanced, the picture is clearer, and the first filling map layer is saved as a third map. The third map obtained through the above steps can be used to add surface details to the second map. The detail feature of the surface detail may be represented using, for example, resolution, number of display elements, etc. And under the condition that the detail feature degree of the surface detail added by the third map for the second map does not reach the first target threshold, repeatedly creating a new filling map layer, and adding texture and color blocking effects to the new filling map layer so as to further take the new filling map layer as a new third map to continue enriching the surface detail of the second map, and finally saving all the third maps when the detail feature degree of the surface detail added by all the third maps for the second map reaches the first target threshold. The first target threshold may be set according to actual conditions. The effect of comparing the details before and after adding the mask is shown in fig. 3.
In step S208, when the detail feature degree of the third map reaches the first target threshold, adding a light and shadow effect to the third map to obtain a fourth map includes:
step 1, creating a second filling layer of a third mapping, and determining the basic color and the roughness of the second filling layer;
and 2, adding a second mask and illumination for the second filling layer to add a light and shadow effect to obtain a fourth map.
In the embodiment of the application, a light and shadow effect can be added to the surface of the third map by adding a mask, and the addition of the mask requires a new filling layer of the third map. After the mask is added to the second filling layer, the second filling layer is saved as a fourth map, so that the fourth map can be used for adding a light and shadow effect to the third map.
In the embodiment of the application, the transparent numerical values of all the maps can be changed by percentage according to the effect.
In the embodiment of the application, the texture effect and the color blocking effect can be added and the light and shadow effect can be added simultaneously, for example, the second map is copied to obtain a copy of the second map, the texture effect and the color blocking effect are added to one second map, the light and shadow effect is added to the copy of the second map, the light and shadow effect can be added to the second map firstly, and then the texture effect and the color blocking effect are added.
In step S210, in order to perfect the blocking effect of the fourth map, optimize the production effect of the map production tool, and reduce the difference of the hand-drawn wind display effect, the first map, the second map, the third map, and the fourth map may be synthesized based on the above-mentioned first map, second map, third map, and fourth map to obtain the base color map and the roughness map of the target object, and the base color map and the roughness map are input into the preset blocking model to obtain the hand-drawn wind map of the target object output by the preset blocking model. The preset color blocking model can be a color blocking module in Photoshop software. The hand-drawn wind map output by the final preset color blocking model may be as shown in fig. 4, where two items on the left side of fig. 4 are the hand-drawn wind map effects of the model displayed separately, and the right side is the hand-drawn wind map display effect of the model in the actual game scene.
Specifically, the base color map and the roughness map of the target object are obtained by synthesizing the first map, the second map, the third map and the fourth map, and seven maps in total are synthesized together to obtain the base color map and the roughness map of the target object.
