r66 Three.js can't load anymore JSON files coming from Blender Exporter.

[zaykho]

Hello,
Recently, I have seen that I can't get to work exported obj from blender with json exporter, even the oldest json files like this one: three.js / examples / obj / female02 /
https://github.com/mrdoob/three.js/tree/master/examples/obj/female02
Doesn't work anymore !

I have BLENDER 2.6.9.0 and the latest Blender Exporter 2.65, tried many options but none did work, tested some recent exported json with older Three.js revision (like r50) and it did work. Even the code exemple like: three.js / examples / webgl_loader_json_objconverter.html
https://github.com/mrdoob/three.js/blob/master/examples/webgl_loader_json_objconverter.html
Doesn't work anymore !

So after many test, this is not a 3d model, exporter, blender, browser or code issue but definitively a Three.js recent update problem causing these exported .json to not work.

EDIT: by saying "doesn't work", I mean it make total garbage on the screen like this:

Haha. That was the most informative bit :)

Just wondering if this even has anything to do with Blender. Have you tried exporting from latest Blender exporter and loading in three.js r50?

Also, make sure you're using the latest graphics card drivers for your system.

I have tested this, and it work great.

Also, make sure you're using the latest graphics card drivers for your system.

About this, I have tried on many computer with latest driver, 2 laptop (1 Sony Vaio vgn-cr11s [intel gma x3100], 1 acer of my friend [nvidia card dont remember full spec]) and a server Dell power edge T-300 with modded Nividia gt-210.

Also tested on Chrome, Firefox and nightly latest SVN, with and without Add-on activated, on 3 different OS: Xp32bit, Xp64bit and Windows 7 64bit.

I must agree that all test was done on low graphic platform, maybe it has something to do with. :/

Does it show the same breakage in all these systems?

What are the specs of that system?

Yes, has far I remember (tried this morning [FR time] in office).

Right now I run on a Sony Vaio, vgn-cr11s:

Directx9, no modified setting in Graphic panel of Intel. (Latest driver coming from 13/01/2010 [driver version: 6.14.10.5218])

But everything work great in r50 (and older), is just when it come to 55+ this "bug" is appearing :/
(didn't tested all version, but found this "bug" on r66, r59, r56, so I assume that everything after r55 have the same behavior)

Ok, my bad it was an error from me.

I forgot to follow the migrating page, then, my error was coming from the THREE.MeshFaceMaterial and the new "material" parameters.

Now everything works great ! Sorry that I didn't look the migrating page before opened this issue.
