Linear Workflow, LV does not equal export

[dh921911]

I thought I had this workflow figured out, but apparently not.

I'm trying to get my linear workflow from Octane to Nuke/After Effects to work properly, but recently all of my renders are crushed and do not reflect what was rendered in the LV.

LV vs Rendering

LV vs Rendering vs NUKE (same with After Effects)

I thought I had ticked all the appropriate settings. Camera response set to linear, Gamma to 2.2, Neutral/Natural response. Render buffer type set to Linear. Image color profile set to linear. Tonemap type set to linear.

So what else am I missing?

Livw viewer is giving tonemapped results. It applies camera imager parameters. Set to linear and gamma=1 should give same results as linear buffer but clamped.

Ok, but now that solution basically reverses the issue.

If I set my camera imager to linear with gamma = 1, then it is literally impossible to see what I am doing in my scene because the colors are so crushed. Also, the output still does not equal the input as now the LV is significantly darker than the PV export.

So this cannot be a solution. Everything i've read on these forums and elsewhere is that for compositing and post work you want to be working in linear. Switching back to the camera response presets does not give accurate results.

If set to Linear and Gamma = 2.2, then export is too dark. If set to Linear and Gamma =1, the LV is way to dark and crushed to be of any use.

Ironically, if I export a still frame directly out of the Live Viewer (with imager set to Linear and Gamma 2.2) then it exports exactly as intended.

I have the same issue. The linear workflow is quite complicated in Octane.

I hope someone will explain every step one day

Of course output of linear buffers will be darker than LV passes due being linear. Settings of camera imager that will not affect any result if you use linear output buffers for passes. After comping the all beauty passes you have apply similar gamma(2.2 or etc.) to get LV results. Don't forget to use 16/32 bit psd/exr/tif.
