Anyone know how to blend color grading lookup tables?

UDK | ColorGrading says only:

Blending between LUT textures
In the game the textures are automatically blended over time (the same time value that was used for the former color correction). The performance impact of blending between multiple LUT is small.

The game blends LUTs very nicely if the camera enters a new post processing volume. But is there any way to blend the LUT without using volumes? I want to change the WorldInfo.DefaultPostProcessSettings.ColorGrading_LookupTable in code. I can change it the way I can change any variable, but it changes immediately. Is there a way to blend between textures in code?

I’d also be interested in this.

Maybe you can spawn a volume with the new grading table at the location of your camera an destroy it at the moment when blending ends? At the same time set the new table to default post process.

That’s a good idea. And yeah, that’s probably the only way to do it. Thanks!
