Hi all,
I’m having issues with one object for some reason out of the 600 that have exported fine. None of the materials are exporting to a babylon file. Could someone please help please
sandbox view in babylonjs
correct view in blender
Regards,
James
I would start with looking at the .log file also created. A log for 600 meshes might be long, You should know the mesh name, so you could just search for the name in the log.
Hi,
I’ve reduced the file down so it’s only got that one mesh in. I’m no expert in blender, I wouldn’t know what to look for in the log file to be honest.
Hi @labris
It’s the .Babylon file I need as I’ve found a workaround to the whole issues I’ve had with the two materials per object in my other models. If I export a bablyon file it keeps everything together as one object so I don’t need to have the workaround of cloning meshes and deleting then etc for that highlight issue I’ve had.
The model for my city exports fine for the whole city and the 600 odd buildings but for this one object, it doesn’t export correctly in the .Babylon format. I’ve had it working fine too for the .glb format so it seems like a strange issue.

I took out the bump shader and it seems to have resolved the issue. I can now export as a .babylon file without losing the textures.
Yes, I do not see that was doing any good, and it is causing baking, which is very non-optimal. If baking is going to be necessary it is always better to do it yourself rather than force the exporter to try and do it. There is no easy half way, like still using roughness / metallic scalars, multiple materials etc. If baking is done in advance, you have a full range of options.
That is the reason for the log file. You have a way to know what was done & why, and be able to solve your own problems.
