I use a png alpha image on all my 2d trees. This is what is concerning me. I'm sure I have done everything right as far as that goes. These objects worked fine on a image I did a few weeks ago.

Thanks for the advise. I found what I ws looking for in the new features manual. Gives just enough info to get a handle on the rest of it.

Thankyou Tig. I knew I was missing something.

Whatevers easiest for your needs, i dont think it makes a difference to the clipping.
