Using TEXCOORD_0 or COLOR_0 as morph targets results in MESH_PRIMITIVE_INVALID_ATTRIBUTE error

1

The spec specifically allows morphing of texcoord and color attributes. [Link](https://registry.khronos.org/glTF/specs/2.0/glTF-2.0.html#morph-targets) It is also supported by sample viewer. The description in [mesh.primitive.schema.json](https://github.com/KhronosGroup/glTF/blob/main/specification/2.0/schema/mesh.primitive.schema.json) is misleading. I will also raise an issue...

occlusion strength is used in glTF with the following formula: `1.0f + occlusionStrength * (sampledValue - 1.0f)` Ref: https://registry.khronos.org/glTF/specs/2.0/glTF-2.0.html#_material_occlusiontextureinfo_strength. This can be restructed to `occlusionStrength * sampledValue + (1.0f-occlusionStrength)`, which...

ktxTexture2_GetImageOffset: identifier not found

I'm getting this build error, while trying to use ktxTexture2_GetImageOffset (even though my IDE can find the function in the source code). I'm now using `ktxTexture_GetImageOffset(ktxTexture(texture), 0, 0, 0, &offset);`...

Use BUILD_SHARED_LIBS instead of KTX_FEATURE_STATIC_LIBRARY

1

Is there a specific reason why the inbuilt CMake variable BUILD_SHARED_LIBS is not used to control if KTX is build dynamic or static? Using a custom variable makes it harder...
