There are plenty of render to texture examples floating on the list

Andrew and Wes have posted to the official Recipies page on C74 on
how to do this, and myself and others have also posted render to
For simulating erase color with a low alpha channel, you can also use
a subtractive feedback system with jit.gl.slab . This is what ive
been doing when I use FSAA, and you can have lots of fun by putting
effects only in the feedback portion, like a simple gaussian blur,
wobble, or the like.
