LUTs do not accept Blend Ranges

[Nicole Hurst]

I tried making a LUT today, and Affinity would export my LUT just fine, except it would not honor any changes I made to blend ranges. I'm pretty sure this is a bug, because I've used blend ranges on LUTs before. Or I might be misremembering things, and this might really be a feature request.

Hey Nicole,

I've just had a look and it seems to be working for me. Can you quickly run through your process of creating them and attach your exported LUT?

I've attached the demo LUT I made, along with video showing how the blend ranges are not working with the LUT.

I'm not sure the video loaded correctly... here's a Dropbox link to it. https://www.dropbox.com/s/yoor1vtgzr1se2a/lut test.mp4?dl=0

Hi Nicole Hurst,
Welcome to Affinity Forums
I've reproduced the issue here. Thanks for the video and file. I'm not sure LUT's are supposed to work with Blend ranges at this point but I will check this with the development and will get back to you. Issue logged.

I'd greatly appreciate this functionality!

I've been trying to create a lut using HSL adjustments to manipulate the saturated reds without also affecting skin tones. Using blend ranges seemed ideal until I exported and discovered they weren't being honoured.

Anybody know another solution?

Hi spez,
Unfortunately there's wasn't progress here yet. I've bumped/updated the original report to bring this up to devs attention again.
Regarding the LUT, i'm afraid there's no way around it but you can always group the adjustments and copy/paste to other document/image until this is fixed.

Hey @MEB, unfortunately copy/paste won't work, I wanted the LUT for non-affinity documents (video grading actually). Thanks anyway, I'll keep my fingers crossed for this in the future!
