[@syzexar]

Thanks a lot! solved my problem!

[@vikingbjorn2814]

Excelent Tutorial, great!!!

[@dddarleeenn]

Thank you for your detailed tutorial! It was really helpful. However, I am facing some difficulties with the retouching and LUT feature, even though my face tracker is below my LUT layer, I can't get rid of the white cast, is there a way to solve this problem? Thanks in advance! (:

[@hiru6542]

You're great ...I like your vdo..keep it up

[@Jvsual]

Hi, great tutorial! quick question, how do you fix the overexposing issue, it keeps happening with all the luts I create. Thanks so much!

[@delisepino5314]

Same thing happens to me

[@LalalL-j4n]

Same question 😥

[@JoaoCarlos-fp6no]

I love love love this video. But there would be a way to put on retouch, color filter and bright teeth altogether?

[@shimingtan3775]

Thank you for your tutorial. I have created some sort like " which character are you" filter, possible for me to add skin smooth and Lut in the filter to make it look nice ?

[@QKnowDesign]

Thank you for watching 😊 and yes, it sounds possible.

[@wolflin5745]

Thanks for ur tutorial. How can I adjust the color tone correctly? This picture can’t see what color it will be adjusted to

[@QKnowDesign]

Excellent question. I work with a reverence pic in Lightroom first and add the settings to the neutral LUT after. Watch the first part of this tutorial: kzbin.info/www/bejne/b6mwYqWYmJmsY6c

Your video helps me a lot. Thank you. Now I'm making eyeglass fitting filters in SPARK AR. However, the face tracker function applies different sizes of glasses depending on the person's face. I want the same glasses size to be applied. Is it possible to edit in Java script? If possible, what can I do?

[@QKnowDesign]

Hi, Junghwan. I think a script is not necessary. Don't add the glasses to you face tracker. Instate use the face tracker patch and link the position and rotation of your glasses to the values of your eyes. That might help.

[@OKKOREA82]

@@QKnowDesign Thank you very much. Where can I set the Instate?

Hi! I just keep getting this overexposure thing IN ALL MY LUTS :( Thought it was at first my real light source but I tried with other filters on IG and they don't look like that with the same light... My colors seem to have like blocks of gradation :( I just can't find what can it be, can anyone pls help me?

[@caioyukitorresmatuda2439]

Hi, i´m with the same overexposure in my luts, did you find any answers?

[@zatic99]

hey, I got this problem too. The way to solve it is that turn off grain increase, vignette, and any of the effect in lightroom. (just left the option to change the color)

[@nickyvazquez]

@@zatic99 thank you so much!! 🤍🤍🤍

[@CherryWhisper]

Thank you for this tutorial!! ❤ Just one question, I want to add the LUT to a scene where I have a sphere with a picture but when I create the LUT it is only white and the background of the sphere doesn't show through, how do I fix that? I'm new to this program and still have a lot to learn 😅

[@QKnowDesign]

Hmmm ... and you use as input the camera texture? The LUT only manipulates the Material. I tested that and yes, I have the same result. No idea if that conflict with 3D objects. If someone has a hint, please comment down below.

[@CherryWhisper]

@@QKnowDesign Thank you for your answer, I actually figured it out now, I got some help from my teacher to apply the LUT directly to the camera and then put in a canvas with the cameraTexture and personSegmentation on the alpha and inverting it, and it worked!

[@QKnowDesign]

@@CherryWhisper cool ... I will try it later :)

How I can apply instagram filter on my long video? Please help..I'm searching this from long tim

[@mr.big917]

hi im so confused how to make a colour lut now, because I get red shadowing and oily skin, before I never had this issue. It seems like filtering and comparisons doesn't help. Does anyone know how to fix this

[@nickyvazquez]

I have the same issue :(

[@johnralik9209]

If I use the new lut with facetracker set 32x1 the result has some smudges, even 8x8 is not good. How should I set it? The old lut with facetracker seems better. thank you very much for your tutorial

[@QKnowDesign]

Hmmm :/ Even the LUTs from Spark AR library?

[@johnralik9209]

@@QKnowDesign Ops, the library luts connected to the patch with facetracker are okay, maybe there is some error in my new neutral lut :(

[@QKnowDesign]

@@johnralik9209 that is possible. Maybe it’s not the best resolution :/

Can we use picker ui with this method?

[@bluemadonna8313]

Hii! Really helpful video :) I have a question and maybe you can help! I'm trying to make my lut and face tattoos work together, but lut doesn't apply on them. My lut makes black colors kinda green but tattoos are still black :( Is there any way to fix that?

[@QKnowDesign]

Work with 2 face meshes. One for the tattoo and one for the LUT. Put the LUT face mesh down below the tattoo face mesh. If you still have trouble add to the LUT mesh in the z-Position 0,01. So it's a little above the tattoo mesh. It still doesn't work, disable the user depth in the materials. Sometimes it's a lot of trial and error... also restart the filter after every step, so the changes can be updated.

[@Ellsss15]

I followed step by step but I don't know why when I go to add the face mesh for the retouch it doesn't appear on the face, is there any way to fix this ?
