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...

This is a low priority issue. Textures in glTF can be reused in any material property which expects textures. This means, that the same texture might be used for different...

DropInViewer Three scene always in foreground

I'm currently trying to get the DropInViewer running together with a normal three.js scene. If I use the normal Viewer class and specify the scene via the threeScene parameter, everything...
