Hi David! My name is Kai, I am a research student currently working on rendering volumetric images in Unreal Engine. I saw your post on an Unreal Engine forum at this link here (https://forums.unrealengine.com/t/updating-texture-used-in-post-processing-with-data-on-the-gpu-without-copying-to-cpu-and-back/125298) And was wondering if you could connect with me to discuss your findings as I am trying to achieve the same but am having much trouble. Thank you
