I used some RPC trees in an animation I did, but they appear to act as billboards and don't rotate with the camera as I animate. Is this because there are multiple cameras or is it just that PRCs suck for animations and I should use actual 3d models for trees?
Look at the tree in the bottom right, it's 'thin'. Several 'dissapeard' as I flew by them as I was looking at the thin side view of the face.
Should I toss the whole RPC tree thing and just use created 3d trees?
RPCs are meant to be used in renderings not in animations. Most people are very happy with them for that purpose. The problem with using them in an animation (as you saw) was keeping the object in 3D.
If I remember correctly you can map those RPC folks to a
mask, and then tell that mask to always face the camera
thus substituting 2d maps for 3d objects to keep the file
size small. And only increase the polygon count using a real tree
when the tree is the hero of the shot.
Yeah, that's what I thought too...but with so many cams flying around, I think it gets confused...Quote:

Hi,
try a Look At controller, so the trees rotate with the camera and always faces it. That should solve the problem.

RPCs are OK to be used in animations. You should be able to fly through them and see them without a problem from any angle.
There are some types of RPC objects that are 2D only, but most people are 3D.
I have used RPC extensivelly with animation since VIZ 3 with no problems. Just do not abuse adding hundreds of them, since they're memory hungry.
