Mask material transparency in 2D camera space.
- [Instructor] In a previous movie in this weekly series,…we saw how to use the camera map modifier…to project UVs onto an object…from the point of view of a camera.…In that situation, the camera doing the projecting…and the camera actually rendering…the shot were two different cameras.…We're going to explore a different use case, here,…in which the camera map modifier…is projecting you these from the renderable camera,…allowing us to build a shader network…that incorporates in-camera compositing.…
In other words, we can mask or otherwise shade…an object or objects in 2D screen space,…rather than 3D X, Y, Z space.…I've got a scene set up to illustrate that.…It's a product shot of this task chair…and what I want is for the background to…seamlessly blend into a pure white,…and even though I've done my best…to light the studio and the cyclorama within that studio…to get an even illumination on that back wall,…it's easier just to do it in compositing.…
And we can set this up so that…an environment background can show through,…
