How to adjust a texture's color levels?

I have a grayscale texture (in RGB space) that I want to adjust the levels.

If anyone is familiar with Blender, I’m trying to do the same thing as a Color Ramp node.

If you’re not familiar with Blender, I’m wanting to remap the grayscale range to a different, custom range. White maps to the left end of the gradient, black maps to the right end, and everything else interpolates in between.

Hi!

I think you can use 3PointLevels node for adjust low, middle and high levels of your grayscale texture.

I suppose that’ll do what I want, but I was hoping for something a bit more interactive. Thanks

Try convert all of the Vectors nodes to Parameters nodes and create Material Instance. Assign Material Instance and adjust all the parameters in real time, without delay and compiling shaders.
