Hi, often when I create a model in Substance Painter and export it and import it into Blender, for example, everything seems to be fine, reflections, surfaces, everything, but as soon as I import the model into Unreal Engine, certain parts of the model that contain the metallic map turn black and don’t reflect no light or background. it’s as if nothing is there.
I thought about it for a long time, what is the problem, I couldn’t find it anywhere on the forums. It was only now that I finally managed to figure it out and thought that if this happened to someone else, it might help them.
Reason:
Apparently the reason is that Unreal Engine is apparently unable to render a metallic map that is pure white, I mean it. I imported my Camaro and the stripes on the hood were pure white in my metallic map and Unreal Engine was unable to render the reflections or anything. No less, when I edited the map in Photoshop and made the white parts more gray, the unreal engine was already able to show the reflections on my model.
Hope this helped
