A problem occurs when the “useDelayedTextureLoading” option is used in combination with metallicTexture and metallicRoughnessTexture on PBRMetallic and PBRMetallicRoughnessMaterial materials. In essence, the material completely loses the roughness and becomes completely smooth (see images attached).
I have prepared a playground with two different loadable scene files.
One with the activated option “scene_delayed.babylon” and the other with the option not activated “scene_not_delayed.babylon”.
I couldn’t figure out where the problem is, can you give me a hand?
