The forester leaves.j3o (Heap space issue)

Troubleshooting import-assets
1

Hello all :slight_smile:



I’ve got a little problem, I can’t import any .j3m files



When I try to import a file with : [java]Spatial model = assetManager.loadModel(“Models/Tree/Tree.mesh.j3o”);[/java]



The game chrashs and I get this:

Does someone know why ?

Thx !


EDIT: I'm gonna try this with eclipse with a nightly build. I'll let you know :)

EDIT 2:

It doesn't work too :

Tried to reinstal Jmonkey SDK but it didn"t do anything…



I don’t have ideas anymore.



Did someone have the same problem ?

3

Did you add the testData lib to your classpath?

4

Yes i did. Look at the line" caused by…" it seems to come from materials

5

mhh seems you are using an old testData lib against a recent nightly.

just grab the tree model and material in the svn repo, and put it in your asset folder.

Ok, thank you.



I tried and now the error is different :

Ok, so I tried to change the VM running settings in ecplise. I tried this:



-Xms512m
-Xmx1024m
-XX:+UseParallelGC
-XX:PermSize=512M
-XX:MaxPermSize=1024M


But it doesn't do anything more.

I also tried to change these settings in ecplise properties (to allow eclipse to have 1024 mb of memory). But it doesn't work...

That's really weird :/
