Hi. I faced a problem setting up PBR material. When baseColor is dark, occlusion Texture gets vanished on faces perpendicular to camera.
Here is a PG: https://playground.babylonjs.com/#N4T555#1
Right after start, front face of cube has very unnoticable texture on it. But if we rotate camera, texture will become more visible. Same effect we can see on sphere where front area has almost no texture.
This effect becomes less noticable if baseColor will be brighter, like gray or white.
But I need to have an ability to change baseColor in a wide range from black to white (material color is changing via UI in my app).
So I’m interesting is it possible to setup material so texture do no vanish in front of the camera.
PS: In my scenes I’m using only IBL. I tried different ones (from PG samples and custom maded) but this doesn’t help to solve my problem.
