When does this happen? Do you have a test case?

found it i guess. it happens when an empty Object3D is created with new constructor:

Code: [Select]
Object3D object = new Object3D(new float[0], new float[0], new int[0], TextureManager.TEXTURE_NOTFOUND);
object.build();

object.getMesh().setVertexController(..);
object.getMesh().applyVertexController();

an empty object created with old constructor throws same exception with different index (1)

Code: [Select]
Object3D object = new Object3D(0);

hope this helps,
r a f t

I'll look into it. But what's the point of using an IVertexController on an empty object anyway?

Try this jar: http://www.jpct.net/download/beta/jpct.jar. The problem was, that the controller implementation didn't require that there is a bounding box but it assumed that at least the space for it is reserved, which isn't true to "empty" objects like these. I hope this is fixed now. This release also fixes the rotate?()-methods.

empty objects created with new constructor still throws same exception ;)
Code: [Select]
new Object3D(new float[0], new float[0], new int[0], TextureManager.TEXTURE_NOTFOUND);

Argh...my test case didn't call build(), which obviously makes a difference. I'll fix this tomorrow.
