Here’s a debugged version of the ColorCorrect tool v2.2. The exported LUT should now work in both Davinci Resolve and Adobe After Effects. I’ve tested the LUT in Davinci Resolve, and it works fine. After Effects uses a specific format for LUTs, which luckily also still works in Resolve, so it’s a single LUT for both programs. Here’s the link:

Edit: for some reason the old version was uploaded before. This should be the correct version.
