please reply to this thread for max 5 jit-ogre questions.

thanks.

Thanks, Ian

which reminds me. there will probably be an error or three that shows up in the max window when you rebuild contexts. prolly safe to ignore them…

I downloaded the new version of jit.ogre but can’t get it to run – the Max window complains “rr.gl.ogre: No such object”.

I assume this has something to do with the fact that when the jitogre_max5_mac.dmg installer is mounted, it contains a folder called “rr.gl.ogre.mxo” (instead of a Max external object with that name).

Any suggestions?

pH

just copy the .mxo bundle to your max file path and it should work fine.

look forward to possible jit-ogre integration with the next release of gl lo-ryder.

check video here:
Maya to Ogre export tutorial

also, from a previous post of dev.sim, the maya 2008 exporter:

Except it doesn’t, which is of course why I posted in the first place.

I do understand that externals are actually folders; I was just guessing that since every single other external shows up as a file, the problem might have something to do with the fact that rr.gl.ogre shows up as a plain vanilla folder.

It’s in my max file path, but as I said, the Max window reports “no such object”. Any idea why? And is anyone else having this problem?

Thanks,
David

i’ve attached a zip of the external. maybe that will help?

Thanks,
David

also, found this online

also, removing the extension, and then re-adding.

very strange. sorry i can’t be of further help.

Thanks for your help with this.

Cheers,
David

Does this mean it’s pointing to file that exists on your drive ;)

I’ve also uploaded a crashlog if that’s any help. This is my first time using ogre (seeing if it will work for an upcoming project) and so am watching the tutorial videos as I get these crashes.

Please feel free to point me elsewhere for more info.

Thanks,
David

perhaps a permission repair from disk utility is in order on the laptop.

did you see this line from the readme?
“You may also need to copy the Cg.framework into /Library/Frameworks, if it doesn’t already exist there.”

check the frameworks there and if that fixes it.

I did, and there was (don’t know why) … so I replaced it and works fine. I’m getting other errors now, but I’m sure that will work itself out once I know what the heck I’m doing.

Thanks again,
David

unfortunately, the wiki is a bit outdated and most of the documentation is in video form, but should get you started.

1. Do you still need to convert your mesh files into non-binary xml? Since the converter wasn’t included in the installer, I just wanted to check. The person I am working with on the model side exported a simple cylinder with texture from 3d studio max using the ogremax plugin. However I’m getting:
error: there is a problem with your material file
and want to help him track down (if its me or the conversion).

2. When I load some of the demo meshes, e.g. the default help file mesh zombie_small.mesh, I first get this error:
jit.gl.render: building GL on window “ogre”…
global draw end: : GL Error: Invalid enumeration

Any idea what the error is?

The ninja has been quite fun to play with! Thanks for providing this external. Very cool!

David

the first place to look for more information regarding errors is the ogre.log file (make sure you first load the mesh which causes the error, then close the patch. that way the file will be unlocked and contain the relevant information).

for kicks, send me your .mesh and .material files that were exported, and i’ll take a look.

the invalid enumeration error can be safely ignored (i think).

your .material file is just a text file, and can be opened with any text editor. looking at yours, all it contains is a comment that says Unsupported material. this means that your exporter was not able to export your material properly from 3dmax. you will have to check the ogre artists/modelers forum for help with that.

this is not a huge deal, because the mesh still loads fine with the default flat white material. the reason you can’t see it is because the cylinder itself is actually quite big (or rather the default jitter gl camera position is quite close). if you scale it down to 0.1 or so, you will see the mesh with the flat white material.

hope this helps.

Thanks again for your help with this. I think I now know enough to be dangerous and will check with my modeler on fixing the export issues.

So what we are trying to do is load in a big freakin’ model of the interior and exterior of the car that is created in 3d Studio Max. To get to this point we’ve been doing a bunch of tests getting to more and more complex geometry, starting with cylinders, then to spheres with chimneys, then a horse…all with good results. Still having some issues with some materials (mainly procedural textures vs. image files), but that’s a question for a different forum. I have a couple of other questions that might be related to here? If not, a nudge in the right direction would be great.

1. First: if my directory contains as huge number of material files, I get a stack overflow when clicking the “get_material_list”. It varies, but points usually to the inlet of the subpatcher making the menu or an object inside, which usually means it’s having issues completing a task in a given amount of time. No amount of defers/deferlows seem to cure the problem, so was wondering if generating the menus needs to be deferred within the rr.gl.ogre object? Certainly not a big deal at the moment since the mesh files all point to the appropriate texture (or lack thereof).

2. Second, and this is where I might need a shove to find more info. I now have 35+ mesh files, which all together draw the 3D model of the car…separately not so exciting. I remember in a past life working with a modeler who dealt with scene graphs that showed how everything is assembled. Is there something analogous in ogre? or is there an external app that stitches together all these meshes into one ubermesh? Again…might be a bit OT for the jitter list, so please say so if it is.

3. I love playing with these complex models and seeing that my CPU % never gets above 10%! But clearly that because the GPU is doing all the heavy lifting. Is there a utility you would recommend for monitoring GPU usage on a mac?

Thanks again for all your help with this.

David

Hey…perhaps that’s what the .scene file is for! drrrr. OK, I need to read up on this more.
