How to dispose textures created by post-processing passes?

[hayden2114]

I posted the details of this issue on the three.js discourse page, which I'll link below and attach a screenshot for convenience. But basically there are textures being leftover in memory whenever unmounting the effectComposer with outline and shader passes.

I'm using three.js version 131.3 and just using the extend function from r3f.

Any help or guidance would be appreciated!

You'll want to abstract these passes and properly implement dispose methods on top of them, this way they're called on unmount. I'd recommend using @react-three/postprocessing or Drei#effects that already do this.
