Hi everyone! I'm having trouble plugging my bitmap textures from Substance Painter to the Karma MaterialX Subnet. As soon as I plugged my normal map (OpenGL) into the normal input of MaterialX standard surface, the lighting completely changes and it is clear to me that the normals are not being read properly at all. Everything in the mtlx normal map node is set to default values, space to "tangent", scale to "1", and the rest are at "0".

Could someone please point out what is causing the issue here? Thank you.

On the mtlxImage node that is reading your normal map, has its signature been set to vector3? If it's still set to color, it is not being read as raw data and has a color transform applied.

Thanks, it's helpful. I thought setting File Color Space to Raw was enough (it doesn't work well).:S
