Hi !

I want to get HDRI that I assigned to dome light into matnetwork to have ability edit that HDRI
how to get that into matnetwork ?

In max for example you just drag texture slot into material editor and creating instance and then colorcorrect or whatever
but in houdini it's hard to understand the workflow.

There is an entire context for image editing inside of Houdini. It is called COPs (compositing operations).
Drop down a COP2Network and dive inside. You can load a file, color correct, and generate a new output.




Inside of SOPs, you have to use a special syntax to fetch the output from the other context. This takes the form of a token called “op:” and you must place the entire path to the cop network inside back ticks.



Here is a scene setup.
