How to view texture crop in vrayHDRI?

I often have maps that consist of multiple product colours and use crop to select the colour I need for the material. As seen here in BBB’s tutorial: Materialism (1)

Is this possible in vrayHDRI? I cant seem to find a button to view the image and move the crop region.

Thanks!

Nope, I don’t think so. I found that limitation recently, too.

Guess something to add to the wishlist then.

It’s already been asked a few times. An absolute basic function. It’s a real shame, that it’s not there from the beginning, and that we have to ask for it.
