@PiBoso,
Could you offer some guidance on suitable texture sizes for normal/specular maps?
If the original texture was 1024*1024 what would you suggest as a suitable shader size without impacting performance unduly?
Is the effect of scaling a shader map down by a ^2 to reduce render time by half or a quarter of the time?
Any other tips for shader map creation?
Are shaders processed using the GPU or CPU?
Thank you.
