OK, I'm going to try to post an example vid so you can get an idea, but I'm notoriously bad at getting attatchments to attatch so lets see..:)

I'm working on a little project that has a face pushing out of a solid object, lets say a wall. The effect I'm looking for is that the wall is rubber and the face is pushing through from the other side. We've all see this in movies before (Frighteners!) But I cant seem to think of a good way to get it to happen. I did the face modeled into the surface and flattened it as a morph but that just comes out wrong. Just for refrence the face isn't going to move along the wall or anything, just push out at one point, talk a little and maby fade back. Anyone have any ideas?

The links not working for me. Whats not working for you? It can also be done as a displacement map as well.

Hey! I gues that's why they call you Sensi :)

What I would really like is that look of something pushing out from the inside. That said, it's only a few seconds in shot so it dosen't have to be that convincing. How would you do a displacement and what difference woudl that give me than a morph. I almost wish sockpuppet or something woud let me use the head model to displace the wall, does that make sense? Maby I'm loosing myself more in this now...:(

You need to run on subpatches to make it look smooth.
You can do this via morphs or displacement map.

Actually it is subpatched (don't remember if it is in the vid, but it is) and that makes it look even worse when it's collapsed.

But even with a morph/displace map, how woudl I go about making it project out of the surface and not just "scale" out?

Render out a depth buffer anim (camera moving towards the head) or use a gradient based on distance to camera. Use those frames as a displacement map or to drive a morph.

ummm....what? I'm no noobie, but I'm not really sure wat our proposing there. Could we try a little more depth to the explination? :)

Lightwave is capable of saving out different internal render buffers individually such as diffuse, specularity etc. The depth or z buffer is one of them. It looks like a greyscale image of you object where each pixel defines the depth from the camera. You can get a similar effect using fog or a color gradient based on distance to the camera. This can be used as a displacement map. Id spend a little time doing a bit of research in the manual on those topics. :)
