I�ve made some tests just before posting and what you described happens when the red, green and blue channels are not enabled whether your tattoo uses those colors or not; even if the alpha channel is enabled, you can�t go into the advanced mode and once you clicked on the buggy tattoo, base game or functional custom tattoos can�t get into advanced mode either; functionality returns to normal if you leave the tattoo table then enters it again.
By the looks of it, the safest scenario is to always enable the red channel even if your image only uses the alpha (white over black, usually for outlines) and alpha itself is not enabled in Tattooinator.
Hope it helps.

Since paint.net doesn't have a channel feature on the layers, I kept the outline of the image black and made the background the pinkish color and this is what I got: this is what the tattoo is supposed to look like when it's done:

I'm going to be another who gives it a go with photoshop, so we'll see how that goes with the reported issues with alpha channels. As this seems to use RGB values as customisable colours, I'm curious as to if you can blend between colours by creating a gradient between say, red and green. For example, could painting like this: Produce something to this effect? Either way, I'll be testing that out myself in a bit. If it works I've got some stuff I'd love to try.

This seems to produce either an invisible tattoo or one that's solid black, maybe depending on how the graphics program being used encodes or omits the alpha data. NummyBiskit: I experimented very briefly with blended colors, and found that if the color intensities are roughly equal green will override red and blue will override green and red. They're layered on top of each other and appear to weighted by intensity. In other words, if you try to do purple you'll get blue with a tinge of purple, etc. You could experiment and maybe get something usable.

NummyBiskit Test Subject Join Date: May 2010 Posts: 13	Got both of these working. :D Blending with RGB proved usable and working just fine, but as you said, a little iffy. I found that I had to leave a decent amount of the base colours at either end of the gradient to get what I was looking for. For Photoshop Users: We handle alpha channeling a little differently, and view it as a seperate layer. To manipulate the alpha layer in photoshop, first click on the 'Channels' tab above your layer. This should show you your individual Red, Blue, and Green channels, as well as one channel to show you the collective RGB values. At the bottom of the window, click on the 'Create new Channel' button. It looks like a page corner. This should give you your alpha channel under your red, blue, and green channels. It should be completely black by default. This is where you copy and paste your original black and white image. You then invert it like in the original tutorial to make the lines white and the rest black. In Photoshop this is found under Image > Adjustments > Invert. You won't need to apply the alpha layer, as you did that when you added the alpha layer to the layer list. So you won't be seeing the applied alpha layer in your image like in the original tutorial: However, give heart and work onwards. It's worked just fine for me both in the Tattooinator, and in-game.

If so, then I'm having a problem elsewhere. Can you (or anyone with photoshop who's gotten this working) post a screen-grab of the settings you used to save the .DDS? When you said "check off", I don't know if that means make sure the check is off, or the check it on. >_<

If you look a few posts up you'll see what happens if you disable all the channels - the advanced settings in CAS stop working.

Plus, disabling the channels has no effect on how the colors look in-game. Doing blended colors is possible but tricky.

Settings: Load mipmaps should be unchecked when opening an image; Make mipmaps should be checked when saving. Maybe someone else can address the DDS and DXT options in Photoshop.

Because somewhere along the lines, I must be doing something wrong. EDIT: And I'm not caring about functionality of changing its color. I just want it to look right. It was from a photo, and uses tons of colors. I don't need the ability to change said colors, I just want it to look decent in game, even if it means all colors have to be set to #FFFFFF in the game's color picker.

I honestly think that given the way tattoos deal with colors, the result will always look like a negative image or something Andy Warhol did...

While it's theoretically possible to fiddle the colors, in practice I don't think you'd ever get it looking right. When I tried I also got the negative image effect that Marcos Edson mentions.

Make sure you're creating the layer mask from the alpha channel, then if you've got a black background in your layer mask when you apply it you should get the checkerboard.

My game/gimp is in swedish version which makes it a little harder. Is there a video clip or something with this tutorial?

TONKaTruckss Test Subject Join Date: Mar 2009 Posts: 5	I'm having a problem with step 4. When I go to add the alpha channel, the option is grayed out. I don't understand why, considering I followed all of the instructions on the first three steps. :p EDIT: Just kidding. GIMP had the alpha channel already enabled it. So all I did was disable it, then do the coloring. Worked like a charm! :D

I tried and got the same results. Probably you have to enable channels in order (red, green, blue, alpha) and the game stops looking as soon as it finds one disabled - you skipped the green channel so the game stopped enabling them after red.
