When cubemap texture is uploaded with GL_LUMINANCE format, sampling it behaves as if the texture had single channel GL_RED format. GL_LUMINANCE should produce grey scale texture.
GL vendor: Imagination Technologies (Host: NVIDIA Corporation) GL renderer: PVRVFrame 10.1 – None (Host : GeForce GTX 760/PCIe/SSE2) (SDK Build: 3.5@3510720) GL version: 3.0(Host : 4.5.0 NVIDIA 355.82) (300) GL shading language version : GLSL ES 3.0(Host: 4.50 NVIDIA)
Thanks for reporting the problem. I’ll update this chain once the PVRVFrame lead has had the opportunity to investigate the issue.
The bug has been fixed for our upcoming 4.0 SDK release (changelist 3755093).
