camera projection uv, texture reference object a la Maya

A simple thing..

In Maya, you can project UVs from a camera. To prevent textures from swimming if you do animate the object, you must create a Texture Reference Object. Here's how you do it in Houdini.

The gist is - 

  • use the UVTEXTURE node to project your uv's. Set the texture type to Perspective from Camera and specify the projection camera in the appropriate box.
  • freeze the object on the frame you want the projection to occur at, using a TIMESHIFT.
  • copy the uv attribute back onto the moving object, using the ATTRIBUTE COPY node.
