Houdini 20.5 will feature a brand new environment for processing and generating textures and compositing them seamlessly with your 3D scene. Internally labeled Project Copernicus, it will be the long-awaited update to the COPs (compositing operators) module.
A few highlights:
Built with real-time/near real-time performance in mind. It's written entirely in OpenCL so you get 100% GPU acceleration. It also uses Houdini's brand new APEX technology under the hood to provide multithreaded performance enhancements where applicable.
Tight integration with Houdini's existing 3D modeling toolset. You can freely import any geometry to use as a texture basis or export texture information to affect your models with.
Live updates to the existing lookdev and rendering environment, so you get live render updates as you adjust your textures.
OpenFX-compatible, so you can use any 3rd party OpenFX plugins (like BorisFX Sapphire for example).
Here is a demo of some truly eye-popping abilities of it (skip to the 7-8 minute mark for the actual demos):
