cube LUT colorgrading

DusX

I just posted an update to my DX – Cube2LUT – ColorGrading user actors (demo file).
It now includes a user actor that allows you to CREATE a 64^ CUBE LUT via 8 color inputs.
These basically allow you to remap colors within the grade to a new range

Please give it a try (requires a Pythoner virtual environment is setup, and numpy and cv2 are installed)
I see this has had a few hundred downloads, but I haven't received any feedback. I'm happy to continue to make updates to these tools if they are proving useful to you.

Hello.
I am trying this patch, but can't get past the file browse step.

I have the Python environment is set up and active.. But I cannot load a cube file. My browser lets me select a file, but the actor says, "No file selected." And once, and I cannot tell exactly how and why, I had an ASCII error as follows: Error: 'ascii' codec can't decode byte 0xe2 in position 197: ordinal not in range(128).

I tried a multitude of LUT files, all with the .cube extension, but no success.

What am I missing out?

Any help would be appreciated :)

The file has a number of User Actors, from your description I am not sure which one is the root of the failure.

DX - PY - Browse for File (win+mac) :

does this user actor allow you to select a file on your hardrive?
does the filepath get inserted to the next user actors 'cube_path' input?

DX - PY - Load .Cube for Color Grading :

does the 'status' output change if you click the 'load' input trigger
if you open this user actor to look inside, do you see a red Hazard symbol on the Pythoner actor?
is the status output = "status: ❌ LUT file not found"

I suspect you will see the red hazard on the pythoner actor once you look inside the "status: ❌ LUT file not found" actor.
Like this:

If you do, then the Python environment is not setup correctly. Scene one requires Numpy be installed, and scene 2 requires Numpy and OpenCV.

If you go to Help/Open Plugin folder in the menu, and read the last line on that menu you should see 'Python Virtual Environment' ...
What does the rest of that line say?

note: The asci error might have been due to unexpected characters in a file name/path.
