Box Texture Mapping

General TouchDesigner Discussion

I am attempting to previz a setup where I need to project on the left, middle, and right wall of a room (and eventually the ground). I am using a Box SOP with a Delete SOP to remove the top and front piece of the Box SOP. I am sending my particle system Render TOP to the material of the Box SOP. However, I can’t seem to set the texture coordinates properly. I have played a little with the Texture SOP, but can’t seem to get it to work properly. I end up getting the particle system textured across on all parts of the Box SOP including the inside and outside of the Box SOP. In the end I just want my particle system across the left, middle, and right face of the Box SOP

Do I need to import a UV mapped box from a 3d program or can I do it all from TD? I know this is most likely a simple fix can anyone point me in the right direction?

Thanks

I can think of a couple of different methods. A fast and easy method would be to use the texture SOP after the box SOP and set it to Perspective from Camera. Then lay down a camera COMP and set the field Camera Name in the texture SOP to the camera. Then set the camera FOV, position and direction.

The other method would be to use a light to project a texture onto the SOP. You wouldn’t have to care about UV coordinates just the light position and projection width.
