sorry to bump this,but how did I composite those light select together in photoshop and match the tonemapped result in vfb? Im only able to get a linear result in photoshop.

If you're going to composite things in post, you must skip tone mapping in the VFB and do that in post instead (as almost all tone mapping will stop the output being linear, and then compositing will not work properly). If you've developed some tone mapping you like in the VFB, you'd have to disable it and recreate it using equivalents in your post editor of choice (pretty straightforward stuff, there's generally a one-to-one in terms of any given tone mapping function).

Also, on thinking about it, if you prefer to use the VFB for tone mapping due to familiarity - you should be able to save the composited but not tone mapped result from your post editor to EXR, rename to CXR, and load into the VFB to use the familiar VFB tools, if you like :) Hope this helps! Tom

Yeah,CXR save works with VFB lightmix,problem is I have to share my output file with my colleague and let him do the lightmix adjustment,while he doesnt have access to VFB, for curve or lut there is 1 to 1 match in photoshop,but for filmic mapping/tone curve part I cant find a 1 to 1 match function, we can get a similar result but not the same as VFB. but nevermind, just use CXR with VFB now.
