Yesterday I created a new LUT using the same parameters (with the correction file enabled) with 994 patches but the result was for some reason very bad with lots of artefacts... I ended up deleting it as V3 and V4 created previously were much better.
One situation I'm getting is when the process of creation the LUT ends, it now hangs on the "Generating gamut views" and I need to cancel to close DCG. Sometimes I get the popup to choose to install the 3DLUT (which I always do) and view the profile, but not always.
After the bad result with that LUT, I spent some time doing a full calibration using the 20points controls and aligning the gamma curve for the Wide Gamut option.
I then configured DCG with a new calibration file for the i1d3 and did a profile only (with the same parameters I posted before and that worked well with V3). I choose for test pattern the "Massive Testchart for Rec709" with a small change to just use 80 neutral patches (instead of the default 140) - 2486 total patches.
I choose this large test pattern because I wanted to let it run unmanned overnight, so that was a way to minimize the time the TV is left displaying the last grey pattern until morning.
So, this morning, I found DCG hanged again in the "Generating Gamut Views" (a believe on "iccgamut.exe" command) but no popup to install the 3DLUT (log file ends with that command).
So, because (I believe) I canceled the process (I had no other choice), I don't have the .3DLUT file and I can't check in madVR how were the results. The only information I have of the profile is that peak err = 1.744424, avg err = 0.340880, RMS = 0.403823 which is a bit worse than the previous V3 with peak err = 1.613902, avg err = 0.311188, RMS = 0.383008
The .icm also seems similar to the ones of previous created LUTs.

Is there any way to generate the 3DLUT using the existing information ?
