The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
The development process of the present application will be briefly described first.
In the prior art, after a high-surface number model is topological into a low-surface number model through related three-dimensional model processing software, research shows that details of the model can be lost, that is, the method can ensure the loading speed, but the authenticity and the integrity of the model can be lost, and the loading quality can not be ensured.
Therefore, after a great deal of researches are carried out on the characteristics of drawing related software and the oversized face number model, a method for realizing quick loading of the oversized face number model and ensuring of the authenticity and the integrity of the model through 'file replacement' and 'file name adjustment' is found and formed, and the specific technical scheme of the method is concise, but is difficult to think of a person with ordinary skill in the art who does not carry out the research process of the application.
Referring to fig. 1, the oversized surface model in the embodiment of the application is a model with the surface number more than 1000W, and the quick loading method of the oversized surface model comprises the following steps:
s1: and (3) processing the oversized surface number model to obtain a model preloading file in a datasmith format, wherein the model preloading file comprises a model body file, a plurality of maps and the materials of the maps, and the step (S2) is carried out.
Preferably, the process of S1 includes: the oversized face model is exported through 3D MAX software to be a model preloading file in a datasmith format.
S2: and replacing each posted picture in the model preloading file with a blank picture with the maximum resolution of 10 x 10, and turning to S3. The purpose of this step is to replace the high resolution map with a low resolution blank picture, thereby greatly reducing the file size.
Preferably, the process of S2 includes: creating a plurality of blank pictures with the maximum resolution of 10 x 10, wherein each blank picture corresponds to a posting picture one by one; and replacing the file name of the blank picture with the file name of the corresponding map, and then replacing the corresponding map.
S3: the model preloading file and the model surface patch with the same material as the mapping are sequentially imported into a UE5 (Unreal Engine 5); the texture of the model surface patch is the same as that of the map in the step S1, and the previously imported map (namely, blank pictures in the model preloading file) can be automatically replaced after the model surface patch is imported. Thus, the mapping of the original oversized face number model is generated in the UE5, namely, the oversized face number model which cannot be imported into the UE5 originally because of oversized files is imported into the UE5.
The working principle of S3 is as follows: the UE5 automatically covers the previous file with the same file name when the previous file is imported, but the file name suffix of the map is automatically modified after the model preloading file is imported into the UE5; for this reason, in order to achieve the purpose of replacing the file of the same name after the import, it is necessary to associate the template with the file name changed after the import of the map.
S3, before the model preloading file is imported, the method further comprises the following steps: the change part of the file name after the map is imported into the UE5 is called a change part, the change part generation information of all the maps after the map is imported into the UE5 and the file names of the model patches corresponding to the change part are modified to be the same identification (for example, space, 1 or 2; taking space as an example, the execution mode is that a file with a notepad opening postfix of udatasmith is used, and the "_2_2_Tex" is replaced by "").
Preferably, the model dough sheet in S3 is generated by: creating a single-sided number of die-type panels, preferably in FBX format; the number of the stickers of the molded surface sheet is the same as the number of all the stickers in S1, and the material of all the stickers in S1 is correspondingly assigned to the surface sheet.
S4: and (3) performing model conversion, packaging and encapsulation on the model preloading file subjected to mapping replacement in the S3 through Nanite, wherein the encapsulated model can be quickly opened in lightweight equipment.
