It is OpenGL
It is difficult to tell because some of the Rhino surfaces have a bad UV by default:

Clarifying Rhino 7 Cycles PBR Normal: It's OpenGL!

It’s important to note that the PBR Normal Map must be OpenGL for optimal results in Rhino 7 Cycles. [image] Normal maps are typically encoded in one of two coordinate systems: OpenGL or DirectX. Rhino 7 Rendered [Rendered] Rhino 7 Raytraced In raytraced, the bump is stronger. [image] However, the comparison between different normals becomes a bit more complex when the light source is at the side - in these instances, all formats seem equal. [image] The difference lies in how they i…
