I just discovered this afternoon that Houdini Engine has the same 10,000*10,000 pixel limit for compositing that vanilla Houdini has.
In Houdini, you can raise this limit in the compositing prefs, but I'm not sure how to apply that change to Houdini Engine. Additional info: Our Houdini Engine install is managed by version control, and we do not have a local install.

For context, I'm trying to render out a 16384*16384 texture from some Unreal actors using a COP network, but I'm stuck with the 10k*10k resolution limit.

Thanks!
