I am a 3d animator, and want to get my 3d models into Jitter. I have created my .obj files, but when I try to load them up, Max/MSP crashes. It doesn't matter how simple my .obj files are...even if it is just a box, it will still crash Max/MSP. Yet, when I tried the Mushrooms .obj file that comes in the examples folder, that works fine. I'm using windows xp (not service pack 2), 3d Max 7 and all the latest Max/MSP & Jitter versions. I have uploaded one of my .obj files here -

I've noticed this problem as well, and as of yet haven't found the reason.

I do know that some programs' obj files will work. E.g. my lightwave

exported obj files run fine on mac, but crash on xp.

I tried your Cinema 4d OBJ model (tried it on a Mac this time (Dual G5 2.0 Ghz Radeon 9600 with 128 MB VRAM, 2GB RAM)), and it refused to load the file (exactly the same thing as what the mac does when it tries to load my .obj models).

Also, is there any reason why there is a .txt extension after the .obj extension on your cinema 4d obj? Is this a requirement for Jitter to be able to read 3d models?

Thanks for your quick responses.

Are you running Jitter 1.6.3? There were some bug fixes with 

Jit.gl.model in 1.6.3 with regard to textures, but perhaps something 

else sneaked in that resolved a crash or two.

Ive successfully gotten models in with textures from

there is no text extension in my file
think it has to do with how you DL it

I've just downloaded Wings 3D and converted my .3ds files exported from Max into .obj files, and they all work perfectly fine in Jitter. That tends to suggest that my copy of 3d Max 7 is not doing its job properly.

One thing ive noticed with the OBJ files is that the format seems to 

be pretty loosely implemented in different apps, so it doesnt 

surprise me at all that some apps dont work.

OBJ is also a pretty relegated file format, there was some discussion 

about supporting a newer more robust 3D file format in Jitter 2.0.

Obviously cycling has no promises with that though

I'm also having problems with models - only with Maya. No obj models that I've created in Maya have yet to import. I keep getting "xxx.obj" is not a model file" in the max window. Though I am able to re-import the obj back into maya with no difficulty.

Any ideas of what the issue might be? I know Maya has the potential to export working models for Jitter but I must be missing some part of this.

ok - interesting. I think this must be some kind of text formatting issue. Basically took one of the working models from the patches folder in the max install, opened with text edit, and pasted the geometry data from my model in there instead.

Clunky but works. Though if you have any additional info as to what I'm doing wrong - pls advise.

Same issues over here. Exporting straight out of Blender as .obj will only load in jitter with certain preferences checked. But even then there are issues to do with normals (i think) the lighting and shading does not work on the model properly.

If I export out of blender .obj then into wings 3d then back out as .obj we have a slightly better result. The shading works but.....

The quads are all triangulated for some annoying reason.

Might try out of sketchUp tonight see how that works!!

btw I got the whole normals idea from this post - these guys seem to have quite a specific grasp on the problem.

Also, while I'm here does any one know of a way to convert illustrator files into a format that can be read into jitter as points or even better as stroke commands. I know there was one other thread that suggested someone got close but not quit there.

if on a mac and using max 4, you can try jit-ogre instead of gl.model.
