Exporter for Blender 2.80

[gryff]

I just downloaded the latest version of Blender 2.80 (posted June 1st called a “Beta”) and took a look.

First think I noticed the “Collections Outliner” seems to have changed again. Gone are most of the little icons - only the “eye” remains. (See image below.). However, there are now check boxes that seem to disable individual collections.

I tried to export to a .babylon file with two versions of the Blender exporter (6.0.10 and 6.0.12) both throw errors and no export. - with all collections enabled and one disabled.

The full fledged release of Blender 2.80 is now due in July I gather (moved from June?).

I know Jeff is a very busy guy and has been putting a lot of time into PBR materials, so where is the exporter headed now?

And I still really like and use the ability not to export certain layers and would really like this for Collections.

I had not noticed Icons are gone. Been that way for at least 2 weeks. Also, 6.0.10 will never work again. I did not do 6.0.12, & never tested it. 6.1.0 with the same change works. Post your log file.

If there is only an eye icon, then it would probably be for visible. Then pickable, & enabled will need to be custom properties unless somewhere else. The checkbox next to the collection would probably be used for export object culling, similar to layers from before.

Exactly my thoughts Jeff. However, I tried the exporter that comes installed with the Blender download and with the latest download from the BJS github site (posted yesterday) . So where is Exporter 6.1 hiding?

I watched a video posted 5 days ago from the Blender folks - the Blender API is stable and will not change. The changes to come are just “housekeeping”.

Ok from the logs:

========= An error was encountered =========
File “C:\Users\Peter\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\babylon_js\json_exporter.py”, line 111, in execute

mesh = bpyMesh.to_mesh(bpy.context.depsgraph, True)
ERROR: ‘Context’ object has no attribute ‘depsgraph’

That is from the version that comes installed with Blender (v10/11) and this from the Exporter on github (v11/12) :

========= An error was encountered =========
File “C:\Users\Peter\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\babylon_js\json_exporter.py”, line 111, in execute

mesh = bpyMesh.to_mesh(bpy.context.depsgraph, True)
ERROR: ‘Context’ object has no attribute ‘depsgraph’
========= end of processing =========

If I create a second collection and add a sphere to it, and then disable that second collection, I get this :

========= An error was encountered =========

self.isVisible = bpyMesh.visible_get()
ERROR: Error: Object ‘Sphere’ not in View Layer ‘View Layer’!

========= end of processing =========

And to add to my day, my KB died and we have had some nasty thunderstorms

Did some double checking, the zip file in 6.0.12 has a defective file. A fix was made to mesh.py, but the changes got reverted due to a conflict. Use this for 6.0.12.

6.0.10 is now garbage. Toss it. 6.1 is all the new additions to PBR / env files. Will look at all changes for the final 2.80

@JCPalmer : Thanks for the link to 6.0.12 Seems to work fine with my latest version of Blender 2.80 - the Beta version.

Don’t understand why when I look at the Preferences - it is listed as 6.0.13, but when I go to export I find “Babylon.js ver 6.0-beta 12”. But no matter, it works, although I still get error message about mesh “not in View Layer” when I disable a Collection. But sure it will get sorted as stability arrives.
