In order to use TraceRays you need a shader binding table and a ray tracing pipeline. I assume that you can only have shaders in the SBT that are also in the RTPSO.
So suppose I have a scene and materials (with custom shaders) dynamically load in and out of it. Do I need to recompile the RTPSO every time that happens? Or is there a way to add and remove shaders to the RTPSO without needing to recompile it?

you indeed need to recompile the pso
you could put all your shaders into pipeline libraries though
then compile the library for each set of shaders you have, and every time you need to recreate the rtpso, all you do is re-link all libraries

does that happen automatically if I create libraries and use them as the input? Or is there an explicit linking operation I have to do for that

creating libraries and using them as input is what I meant by "linking the libraries" yes
