Babylon Blender Exporter material not exporting correctly

Questions
1

I’ve got an object in my world whose material doesn’t seem to be exporting properly with the Blender Babylon exporter, however if I export as .glb it works fine.

This is what it looks like when exported with babylon exporter (no texture):

table_babylon
table_babylon890×615 35 KB

And this is what I get when exporting it as glb:

table_glb
table_glb682×506 169 KB

This is the log file:

I can upload the .blend file if required, just haven’t done so to this post because it’s larger than the 4mb limit.

Is this a limitation of the exporter (NodeReroute node types)? Will it be coming in a future version, or how could I get around this?

First, by default the textures are embedded in GLB. They can also be for the Blender exporter, but need to turn on. While in dev for a material that needs baked actually better to be external.

Start by posting the various texture files generated in the same directory as the .babylon file. If you are showing pictures from the sandbox, these files also need to be selected.

Your picture of just the geometry is also very dark.

If you could share the .blend files I’d be happy to take a look! :smiley:

It’s probably your material node tree which have to be tweaked.

@sairens hi! Were you able to get it working? :slight_smile:
