No luck importing a LUT into created in 3rd party software

Hi, does anybody know how to modify the .cube file created in Photoshop or Premiere Pro for it to been able to get imported into URSA Mini Pro?
For now only those that were created via resolve could be imported.
I can only import them to resolve and output them from it for the camera.

Hi there,

Have you opened the files in a Texteditor to compare how they differ in the header and general structure?

I remember I once loaded a .cube from PS to an Ursa Mini, I think I modified the header a tiny bit.

If you can import them in Resolve, why not try to export again from there and see if they are accepted?

Uli, from there they are accepted, but this is one extra step to operate.

Lucas, yes I've tried to compare them and make them similar and had no luck with that too.

So none of us knows a proper guide?
