Yeah I feel like in terms of allocation count, names are a much bigger problem. Whether we want to address it or not is unclear. cgltf doesn’t currently parse names...

That's what I ended up doing in user space for now: https://github.com/zeux/meshoptimizer/commit/91011f44c1b758412ca34f91b976ad887f10610b However, I don't think it's the full story really. Let's say we do that - do we force...

@jkuhlmann Yup, I believe so!

> const float* position_data = (float *)position_accessor->buffer_view->buffer->data; This ignores any type of offset that might apply to the accessor. I would recommend using cgltf_accessor_read_float or cgltf_accessor_unpack_floats helpers to read any...

One more small issue is that after installation, KTX-Software folder in Program Files has an executable file with an empty name (probably the uninstaller?)

Copying the comment from #524 on some future work involved here; the issue will stay open as the algorithm improves further: - The attribute metric is not perfect - it's...

Looking at this again, this is probably specific enough that glTF-Transform would be a better fit.
