Every time I set the material, click Save persistence, and then load persistence. I can't load it. Who knows, help me.
you dont understand this: When you do "Save persistence" then all changes you made to materials and objects will be saved. When you then do "Load persistence" , nothing will change, because you just saved just that. Its meant mostly for the next time you load the track or if you change the persistence file manually. Its just a text file, same name as your fbx, with "....fbx.ini" extension
There is this file, but when I open the track and execute "load persistence", I cannot load the previously set material parameters.
But every time I open the FBX file, I have to reset the material parameters, which is a troublesome thing
Are all material names called like "FBX material..." ? Then this fbx has no materials assigned to objects/meshes!
Do you have the images in a folder called 'texture'? The editor will only reload images to this path. If you open to the persistence file, you'll see there is no path specified, it's just the filename. If not, I think you'll have to post some files to see if we can recreate the issue.
make sure you only use normal basic latin letters for the names of materials or objects in the fbx file. If you use special characters the persistence file will just stop being created the moment it comes to a name with those in it. Happened a lot to me with accidently use of ä, ö or ü.
