Hi there,

I'm trying to use my 3D objects exported from Lightwave 7.0 in Processing - but it doesnt work.. Do the files need any special settings? The *.obj is loaded, but drawing doesnt work - does anybody have an idea why this can happen? I tried also very simple objects with only few polygons..

In the sample I found somewhere here is also a material file in the data folder. As Lightwave didnt generate any relating *.mtl file I tried to use the one from the sample by renaming it and copiing into my data folder - without success..

Processing complains:
__________________________________________________________
model loaded

java.lang.NullPointerException
at saito.objloader.OBJModel.drawModel(OBJModel.java:151)
__________________________________________________________
susanne

It's just the basic stuff. I took the sample from saito object loader, (which is working) and replaced the included object with mine. It looks if it were a format - problem. We tried to to it with various *.obf - files exported from different 3D - applications - all of them didnt work - except one exported from 3D Max.
