## KHR Texture Transforms
-Texture repeats for PBR materials on prims are based on the [KHR\_texture\_transform](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_texture_transform) spec, and thus should be expected to behave according to the spec.
+Texture repeats for PBR materials on prims are based on the [KHR\_texture\_transform](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_texture_transform) spec, and thus should be expected to behave according to the spec. We currently suport offset, rotation, and scale from the spec. texCoord is not currently supported.
PBR materials should have approximately correct lighting based on the normal texture:

## PBR Terrain Texture Transforms
-Like PBR materials on prims, PBR terrain repeats are based on the [KHR\_texture\_transform](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_texture_transform) spec, and thus should be expected to behave the same way.

We currently suport offset, rotation, and scale from the spec. texCoord is not currently supported.
The southwest corner of a region, at z=0, is the UV origin for all texture coordinates of the whole region. Unless an offset is also applied, scale and rotation of the terrain texture transforms are relative to that point.
