Problem with convert and import models

bobson · November 2, 2012, 7:39am

I got a scene in 3d max 2012 with objects, please give me advice, how to load it to jme3 for use it like an array contains objects with textures, positions and other object’s properties?

In my case I want to load scene, make a different actions like a rotation, move and others with some big and little objects in it.

try MaxToOgre script .

Has ony one example of usage few objects after they are loaded with assetManager.registerLocator?

javagame · November 2, 2012, 10:11am

What exactly is it that you want to do? After you have loaded it with the assetManager you can manipulate it then attach it to the scene, I guess

[java]

Node model = (Node) assetManager.loadModel("Models/whatever/model.j3o);

model.setLocalTranslation(5,15,-6);

model.setLocalScale(7,1.9f,20);

rootNode.attachChild(model);

[/java]

You need to go through the documentation if you don’t know this https://wiki.jmonkeyengine.org/legacy/doku.php/jme3#tutorials_for_beginners

I read it today again, but I don’t understand, uhm, if I load like a node, so I can get childs, thanks a lot, will try later. One more question, i found 2 plugins for import to ogre xml, install them, and now got in 3d max 2 import variant (ogre and ogrexml) with different settings, try both, work - no errors, install xmls and they loading in my program with parse errors. Also I have checked true to import xml too, but parse error still coming to log…

Can some-body write here or in wiki how he do it himself?

here is some log from application’s start, I create a zip archieve with different models, try a tutorials, and all were fine, but when I try to load 3d max scene I found a problem “How to manipulate different objects from my 3d max scene?” so I go here for help.

I create a simple 3d max scene with box, tube and others objects (figures)
I download and install ogre plugin and .dll for 3d max 2012
I export 3d max scene to ogre xml scene
I got a few files like .mesh, .material, .scene
I put it into my zip
assetManager.registerLocator(“Objects.zip”, ZipLocator.class);
add light (DirectionalLight)
Node simple = (Node) assetManager.loadModel(“Scenes/Test/Simple.scene”); rootNode.attachChild(simple);

Momoko_Fan · November 6, 2012, 2:05pm

Are you using RC2? The line numbers in the trace don’t match the latest jME3 version.

normen · November 6, 2012, 2:19pm

From all I can tell this is an Eclipse/maven setup with the inherent setup issues. Wheres those maven guys anyway? We should close that repo as its not being updated.

bobson · November 7, 2012, 1:36am

Yes, I use Eclipse + maven, I found example in google, with next code:

That is the latest version of jme? And did you know actual repository?

That's probably not the latest. The JME developers do not maintain the maven version nor did we setup the repository, etc.. So I don't think we know what version it actually is and I don't remember who set it up or whether they are still paying attention. Hopefully if they are then they will respond here.

Empire_Phoenix · November 7, 2012, 2:01am

Load from svn, or the nightlys, the maven stuff is outdated.

I configure local a jme3 jars, but still got some error, here is the scrren

I think that I do some-thing wrong, but what?

pspeed · November 7, 2012, 7:24am

Seems like maybe something is wrong with the ogre file you are trying to load.

bobson · November 7, 2012, 8:46am

Yes, it is a pity, but I had a problem with export from 3d max 2012. Try to export to obj, but have in log “WARNING: Unknown statement in MTL! tf”

bobson · November 7, 2012, 9:14am

I try different various and got problem with export my 3d max scene to ogre xml, seems like .scene + .material + .mesh.xml not compatible with jme3

Sorry, if you choose to use a completely outdated version of jme theres nothing we can do for you.

bobson · November 8, 2012, 2:55am

Today I try a latest version and have a same errors, can you write which version of ogremax plugin do you use?

normen · November 8, 2012, 3:22am

You are aware that your model still needs to be game compatible, that is no extended material settings can be exported from the editor? Only meshes and uv maps for textures. So you cannot set a “shiny material” in the editor, it will not translate.
