Hi,
I am having trouble setting up a material in Redshift using latest version av C4D and Redshift so that it exports correctly as a <Mask> material to gltf.
Gltf <Opaque> and <Blend> material is exported as expected but no matter how i plug my alpha texture into the Redshift material it do not export as a <MASK> gltf material.
Since gltf mask material is a cutout material it needs a alpha threshold to make adjustments to what should be opaque and what should be transparent. Using at Sprite node in the Redshift material this information is available but it is not written to the exported gltf file. I have tried multiple different texture format both with and without alpha, but without correct result. When setting up the same material inside Blender it exports the alpha clip texure as the alpha on the diffuse texture but Cinema 4D does not. Does anybody know how to setup such a material inside Redshift so that it gets exported correctly? Hopefully I`m doing something wrong so that it is possible and not a feature missing or a bug.

Thanks.
