While testing a few basic materials in Substance Painter, I’ve put the same material on two adjacent parts of the model, using tri-planar projection, they look quite alike.
However, inside Unreal the two areas of the model with the same materials look considerably different for no apparent reason.
Hi. If you exported the textures with Unreal Engine profile, you must have a texture called something_OcclusionMetalicRhoughness. Open this texture in the Unreal Engine, and select sRGB check box, then set them to disabled. Then your material will be bad. Open your material, select this texture and set the type from color to Linerar Color
My bad (big time). The reference to the Occlusion/Roughness/Metallic was erroneous in the material in UE4.
Thanks man I know all of that, just the reference to the image was error-invoking.
