Possibility to add Modded block textures?

[Explode007]

I was wondering if it is possible to import other block textures and generic information to be rendered. I would like to be able to view structures saved with litematica or create schematics and view their blocks. This would make it quite simple to also visualize PonderJS structures for creation of custom ponder screens.

Im not sure if im correct on this, but since it can recognize modded NBT data and properly lists it in sNBT and even on block palette, its just a matter of it not finding the assets to render it in the 3D viewer no?
