I don't remember that exactly. I guess, because I actually didn't consider this to be important at all. IIRC, it wasn't supported properly on a lot of older devices anyway, so I'm not even sure how well jPCT-AE handles this setting. Maybe we should take a step back: What exactly are you trying to achieve?

Yes, it can.

That actually doesn't matter. The picking works in exactly the same way (see private void relocate() in the example).

Yes, I got that. And picking is the way to do just that. Actually, the wiki page contains everything that you have to know to get at least the picking itself working. What exactly does "it doesn't pick" mean in this context? Have you checked that your picking coordinates correct?

You can implement picking like so: http://www.jpct.net/wiki/index.php?title=Picking

In addition (to get the polygon that's affected by picking), you have to add a CollisionListener implementation of your own to the picked object, that returns true on requiresPolygonIDs. You can then ask the collision event for the polygon's id and armed with that, you can "guess" which side has been picked. The mapping between ID and your side has to be done by youself, but it in case of a cube, it shouldn't be too hard to figure it out.

Apart from that: We are talking about Android/jPCT-AE here? In that case, you can't do it this way unless some more setup work which might not be worth it. There's another way, though. You can tweak the rotation matrix directly. This has some drawbacks as well, in particular it might increase a light source's brightness on the scaled object when it shouldn't and it doesn't work well together with the build-in scale methods. Anyway, this is how it works:

Matrix scale=new Matrix();
scale.set(0, 0, 2); // 0,0 for x-axis scaling, 1,1 for y, 2,2 for z
obj.getRotationMatrix().matMul(scale);

If you otherwise don't change the rotation matrix, you only have to apply this once. If you set it to a new anyway in each frame (or even sometimes), you have to apply this afterwards. Also keep in mind that scaling is cumulative. That means that doing this by 2 and then by 3 will result in a scaling of 6.

I'm not sure why the solution you've posted doesn't work in your case. Or in other words: I think that I haven't understand your problem properly!?
