I have upgraded from version 1.3.14 to 1.3.24 and now this error.
Hi @swavec do you have a sample scene that repros the export issue?
@swavec can you try with version 1.3.25 ? I made a recent fix for another issue that may be related.
1.3.25 is ok , objects with texture were cousing error. Now exporter stops if texture file name has empty space.
@swavec I just merged another fix for this: fix glb export by kcoley · Pull Request #430 · BabylonJS/Exporters · GitHub
Could you try against 1.3.26 ?
Tested 1.3.27 and all is working perfectly.
