I have a question. What is the best normal T- space for models in sketchfab? Because I make normal from bent normal using Hand Plane and I was wondering what settings are the best - or maybe I`ll ask in different way - what poular engine is the closest to Sketchfab player in terms of showing normal map?
Thanks and cheers:)
Sketchfab normal maps are applied in tangent space, without any special effects, like nearly all real-time engine (as it's the most efficient/flexible)
Other normal maps are for very special effects, that might work on sketchfab, but without any specific tweak engine side.
Bent normal is often used for precomputed occlusion/lighting
Smoothed normal for Cell-shading / toon effect,
etc.
