Switching slab shaders with no pause

Switching slab shaders with no pause

Hi, first post here… New to max in general.

I have not found a live visual program that really suits me well, and I do not want to bend them to my will through large amounts of midi programming, so I thought of trying to build one with jitter. I have had enough experience with programming and graphics in C++ so I feel I have picked up max quickly enough.

Anyway, currently I have made a little system using poly~ so as of now I have 16 clips and my video channels and use any they want. I am now trying to implement shaders. I want to combine the video channels together with a slab. However, I want this slab to have say 16 shaders preloaded which I could switch between with a tap of a button. What is the best way to implement this? I guess I cannot do it with one slab object. I was thinking I could have a poly~ system which would mean 16 slabs. Or I could make my own fake slab object with 16 shaders, if that would mean immediate changes. However, can I do this and keep everything 3d accelerated

Thanks!

You should have 16 slab objects if you’re going to use 16 shaders.
shaders have to be compiled on the graphics card and this takes quite
a bit of time. If you’re always loading new shaders, you will notice
slowdown in your video. I would just use a poly~ or JS to switch
between shaders.

best.
