Material bug with --instance

[GrikFreak]

Hi,
I'm transforming my model with this
npx gltfjsx Model.glb -t -k -K -m -s -w -p 8 -d -i -I -T -a

and loading it with:


<Model position={[0, -1.7, 0]} scale={1.8} />

But i see that there are some errors in materials with textures applied.
I'm doing something wrong?
I also noticed an fps rise without the -i and -I command.
Thank you
