Question : How to unpack normals #17

NidoKota commented 1 year ago

I have a question about how to unpack a texture.

https://github.com/keijiro/HdrpVatExample/blob/master/Assets/VAT/VATHelper.hlsl#L30

I am not sure what the process is for extracting the normals packed in the textures. I have searched the internet and could not find any information on this. Also, I could not find the source code to pack normals in the SideFX source code. I am very sorry for the inconvenience, but could you please tell me what the process is? Thank you in advance.

I can't remember it correctly, but I think it came from the SideFX source code. You may not be able to find it in the current code set... It was 4 years ago. Many parts of it might be changed.
