I've been several hours trying to understand why this always returned zero:

I finally came up with the problem: it only works when it has been transformed at least once:

I couldn't reproduce this problem. I changed the Knight Demo based on the picking example in the wiki. Then I removed the setNodeTransform calls from the knight and the sphere and picking still works as expected.

Could you provide a little bit more information about your scenario where the picking fails?

Try also quitting setModelAnimParams

I had done this already. I also removed the setupModelAnimStage calls. And it still works for both the sphere and the knight. The only thing that will be transformed now is the camera. But I cant remove that transformation because then I don't have something to pick anymore

Could you try to debug into the pickNode Code within your application, to check the values of the transformations when your picking is not working?
