Adjusting texture with complex curve?

Hi there,

I already spent a good amount of time searching the internet for a good solution without success, so I hope you guys can maybe help/point me in the right direction:

I would like to adjust a (hdr) texture similar to the curve tool in photoshop (https://rockymountaintraining.com/wp-content/uploads/2012/05/Photoshop_ss_004.png), but with lots of controlpoints on the curve (max. of 21, at least 11) that can be controlled/adjusted/blended in the game at runtime to control the contrast of the texture very accurately.

I would prefer a solution with BP, but I am happy to look into other solutions as long as well. Any ideas? Suggestions where to look next?

Thanks for any help, Toby

Since this has been addressed in 4.20 with the introduction of the curves, I am marking this as resolved.

Create new curve (linear curve), create curve atlas and add the aforementioned curve to the list
