I can get a shader to read in two textures but for output it seems there is only gl_FragColor. Is there any way to render to two different textures from one shader? I am using Processing and the GLGraphics library btw.

Yes, you can write to gl_FragData, which is an array of outputs (size depends on your implementation). Or with newer versions of GL, both gl_FragColor and gl_FragData are deprecated and you declare your own
outvariables for the fragment shader to write to. Declare multiple suchoutvars for multiple output buffers.
