How to use VAT with Shader Graph

At first, export VAT files from Houdini. It consists of a geometry file (.fbx), texture files (.exr) and a realtime data file (.json). Then import .fbx and .exr files into Unity. The texture files must be imported with the following settings:

• sRGB (Color Texture): Off
• Non-Power of 2: None
• Generate Mip Maps: Off
• Format: "Automatic" is recommended. You can select a lower BPP format with sacrificing quality.
• Compression: "None" is recommended. You can try other options, but usually, they don't work with non-power of two textures.
