Hello everyone,


I have been searching the help files for a technique to do camera projection mapping in houdini 6.0 and am not having any luck

It a technique that is possible in maya and lightwave, so hopefully houdini can handle it as well.

It involves projecting my background image (live plate) from the camera onto geometry as a texture so I can then do animation on the geometry for perspective shifts and other fx.

Does anyone know if it is possible or if there is a workaround??

Any help would be greatly appreciated!!

Hi waibeans,

In the UV Texture SOP, there is Texture Type “Perspective from Camera” which is what you're looking for.

Cheers!

There's also a raft of other issues to deal with, but I assume if you've done this with other packages then you're familiar with them. For example you'll often have a cam that doesn't move which you will project from, then move another cam. This still doesn't deal with geometry behind geometry from the projected cam, though - so there's more to it than simply projecting and then moving around.

Also, many people prefer to project from a light, which is possible too. As usual, there's many approaches in Houdini…

Cheers,

J.C.

great..

I will try out the uv texture sop solution.

thanks for the help!
