I've been given a low-poly game asset by a client. I'm setting it up in C4DtoA and I'm having issues with the normal map.
The asset and all its texture files are symmetrical across the x-axis. When I load it up in Arnold, the normal map appears to be flipped in the y-axis across one side of the model.
I've tried setting the normal map to object space instead of tangent space. This solves the flipped-on-one-side issue, but the normals aren't correct.
I've attached a screenshot. The top image is in tangent space, the bottom in object space. The texture applied to the model is a standard surface with the normal map attached, and absolutely all other parameters are at default settings.
Thanks in advance for any insight on this.
