OK, I posted this once, but with no prevail so here goes round 2!
I set up a scene where I have a background with a pic of a donkey. I want to replace that donkey with another but I want to use the old donkeys skin so that the model fits perfectly into the scene - lighting e.t.c....but I want to keep the footage. So I wat to end up with the same donkey, but in model form that I can now animate.
This is how I attempt this.
I model the donkey from the ref in the background pic, I then add the camera map modifier to the model and add a material to the model, that consists of the background map in the diffuse, with self illumination = 100.
The problem now arrives!!!
I now need to burn the camera map that is on the model into a texture sheet. How can I go about doing this - don't mention max 5's render tot exture please!! That splits the texture up in weird ways - and when you put a uvw map on the model it messes up the camera map modifier and material. Arghh help please.
If you are still confused here is what I am talking about but done in maya - translate to amx would be helpful. Thnx
..Next, create a texture reference object for the selected surface to lock the projected 2D texture to the surface. ( In other packages you can 'bake off UV', lock the UV's or write out a new UV texture map.) As the surface animates or deforms, the texture also deforms accordingly. see link at http://www.a3d.pwp.blueyonder.co.uk/maya/camera_projection.html
