Channel Packing In Gimp | Channel Packing Series

[@Triple88a]

I have 2 images, one is rgb, other one is alpha. I've had 0 luck adding them together. Gimp seems to be replacing the main image when i try to copy the black and white alpha.

[@RobertO-vc8vn]

Does not work. No matter what I do when I select the channel and then select the red channel and paste, it paste the same image in all three channels. Next I select the green channel and paste a different image and it over writes the red and paste that image in all three rgb channels. No mater what channel I select it pastes the same in all three channels and over writes what is in there.

I'm a year late but this video is all wrong. You cant directly paste stuff into the channels, you have to decompose the image and then recompose it back together. Theres another tutorial that teaches you exactly how to do that. kzbin.info/www/bejne/ambVkH-VbJiEaNE

[@lele974974]

What version are you using? I tried it and it worked right away!@@realcoolguy123

[@WednesdayTheClove]

pasting works in photoshop but not gimp for me. It always pastes as a layer in gimp

[@fnafgamer2469]

Dude. You are a legend. I’ve been making artworks of Final Fantasy 7 Remake in blender, and some of the Image Textures for some of the models I download had this type of texture. (And I didn’t know what it was called cuz it was just pronounced ‘M’ or something like that.) and I’ve been wanting to make this type of textures for a while. Thanks a lot man!

[@GetLearnt]

Ha, happy to help out! Ya, you will see them called a whole bunch of different names, like 'comp', 'rma', 'pack', etc. But, they are all ultimately 'channel packed' images. :)

I've tried for hours upon hours of making this happen. I come from Photoshop, where this was a piece of cake to create, but since I don't want to pay for PS on my own project, I choose Krita first (didn't work) and now Gimp. Whenever I paste the greyscaled image into a channel, all 3 (R,G,B) channels gets the greyscaled texture, even though I have ONLY selected the one channel. I cannot figure this suppousidly super easy method out, and it's starting to drive me kind of insane... Pleaes, for the love of God, get this man some help D:

[@GetLearnt]

You're not alone, I had a bit of a time trying to get this to work correctly for this tutorial... Truthfully I'm not entirely sure why it packs all three channels, even when you have one selected. I believe that's why I had actually turned off the other channels while I was copying and pasting, I think it let me place a texture into each individual image without just pasting it into each channel. If GIMP is still being a pain, I'd recommend you take a look at Photopea. It's a free browser-based app, pretty much exactly like PS. I just tested it and editing an images channels are very straightforward. Link below will take you directly there. :) www.photopea.com/

@@GetLearnt Tried Photopea and I’m still having that same issue.

@SpotRaid Thank you very much dude! This response made my day :)

[@tekanobob]

@SpotRaid its color component compose FROM a greyscale image allows you to make a RGB from your 3 seperate premade gryscales already open in the list, thank you very much just about to give up the video does not work GIMP pastes into Layer not channel and also some floating non anchor bullshit. soing it this way saves a lot of grief thanks

[@roygatz]

Man, you are very well spoken, how long did you rehearse for this or just speak as you go?

[@GetLearnt]

Hey thanks! I've been doing this for 4 years by this point, so that certainly helps! I map out where I want to go with the videos and I will maybe think about a few key things I want to say, but truthfully it's mostly me just talking at a computer screen, trying to have a casual conversation. I will admit, video editing makes these much more viewable than the raw footage. 😂

[@Azrael_Bathory]

On Gimp 2.10 and newer it seems to be laid out a bit different. For people having the issue when you paste an image into a channel and it pastes it into all 3 channels, make sure only the channel you want it pasted into is highlighted because I was doing that. Also if you go to export the final image and it exports as one of the individual textures, you can fix that by looking over at the layers section of the project, if there is a layer named Floating Selection, click the anchor button (it should be highlighted green) this seems to glue everything together so when you export it now, its the combined channel info. -Hope that makes sense and hopefully this can help someone in the future-

[@GetLearnt]

@@Azrael_Bathory Beyond appreciative, thank you!

[@flajflaj]

The idiocy and nonsense level of how this is done in GIMP is simply epic...

[@GetLearnt]

I strongly debated whether I should even make a video about this in GIMP, seeing as how difficult it was for me to get it working. I'm unsure whether the process has gotten better, but my goodness was it unnecessarily difficult to accomplish for seemingly no real reason at all. :/

[@flajflaj]

@@GetLearnt imho I think it's just easier to mix the textures in Blender (compositing tab, combine RGB), this is how I do that :-).

[@GetLearnt]

@@flajflaj At the time I hadn't thought about compositing in Blender, honestly a much better way to go tbh!

[@AXLplosion]

@@flajflaj i needed a quick channel packing workflow for a project im doing right now and this works like a charm, thank you!

[@dukkemonterier3429]

Talking about almost EVERYTHING on this program.

[@felixmikolai7375]

excuse me sir, i want to merge some texture maps for my game, i try to put my roughness map into the alpha channel of my color map but nothing happens if i copy and paste it. not sure what ive missed..

[@GetLearnt]

I had a little trouble with GIMP when making this tutorial, sometimes it just didn't want to paste into the channel. Unfortunately I don't really have much of an answer for this, I just kept brute-forcing it until it worked. 😕

[@KiwiHawk-downunder-nz]

I was trying the other day to unpacke a channel packed image to I could get the AO, roughness and Metallic out as single maps BUT that is hell on earth in Gimp, I selected the channel and CTRL C to copy but no matter if I paste as a new layer or a new file it did not do it well at all

[@GetLearnt]

Ya, it's honestly brutal, I'm not sure how I even managed to get it to work for this video. 😅

[@captainawesome2226]

Nah GIMP is still completely broken. It can't channel pack to save itself. In Unity, smoothness goes in the alpha channel, but the alpha channel in gimp paints in alpha instead of greyscale so it's impossible to see what you are working on.

[@GetLearnt]

Ah thats unfortunate, was really hoping it would be a better experience by now. Seems like GIMP may not be a good place to author textures then if that's the case.

[@vinnypassmore5657]

Freckin excellent stuff, thanks for sharing, well presented and spoken.👌

[@GetLearnt]

Happy to help, thanks for watching! :)

[@irathil]

Great tut. Liked and subscribed.

[@GetLearnt]

Thanks for checking it out! Glad to have you around. :)

[@williamgodwinACAB]

I'm just use combine rgb node in Blender)

[@GetLearnt]

Totally a great way to do it, I might make a short video on that as well, hadn't thought about that! :D

[@antoinedevldn]

Thanks
