I am having trouble with assigning of custom textures to models. Let's say I have a model that is already imported in the engine and I want to change the texture in editor by enabling the custom materials. So far it works well and the textures are displayed correctly, but the problem is that the textures keep reverting to the original ones.
This seems to happen quite randomly. Sometimes they revert back after selecting another entity or moving the selected model, but sometimes after reloading the level this does not happen, but the textures disappear again when saving the level. Sometimes this happens with all textures and sometimes for example just with the surface texture.
This behvior is quite puzzling to me. Anyone got any suggestions?
