C4d projection, like a real projector

[simonbronson 0]

We were trying some camera projection as in simulating a real projector and found a nifty technique.

 

Camera mapping a texture and also adding a texture to a light both have their disadvantages.

Camera mapping technique means all of your objects need to be grouped and you get tearing . Using a texture on a light wont respect perspective when you move the light back in z.

 

If you nest a camera in a light, add a texture to that light and set the mapping to camera mapping of the nested camera you get a result as you would with a real projector.

The advantage of not only being optically correct is that you can project onto an object with existing textures.

Anyone else worked out any other methods?

Sweet technique, thanks for sharing.

 

I was wrangling with this a few months ago, now I know what to do next time.
