So, I've been following this tutorial and I'm currently at step 32 but I'm completely stuck. I use GIMP and have googled around for answers for about an hour or so without finding anything that helps. I know for a fact it's not possible to "copy x channel to y channel" though. I tried the color>components>decompose and color>components>compose commands without success. The "recompose" option is greyed out. Can anyone help me? Bump map file
Context: I've made a frankenmesh dress from a BG top and skirt.
Edit: I want help editing the alpha channel and the red, green and blue channels. |

I know you said you tried the decompose, but perhaps you missed a step? I hope this post will be helpful. To convert a regular normal map to a Sims normal map, the Green channel becomes the alpha channel, and the Red becomes the RED, GREEN, and BLUE channels. Paint.NET doesn't look like it has the feature to edit the channels separately. I'm looking in GIMP (another free program) if this is possible, and so far I'm not seeing if it's possible either. Keep you posted. Edit:
If you're willing to download and use GIMP. 1. Open image in GIMP and select Colors>Components>Decompose 2. Select RGBA 3. On the Layers menu at the bottom right, right click the green channel and select "Duplicate Layer"  4. Left click and drag the duplicate layer down so it's above the alpha channel. Then right click the duplicate layer and select "Merge Down". 5. Repeat this for the red layer twice, merging once over green, and second over blue. 6. Once finished, go to Colors>Components>Compose, and select the RGBA in the popup.
7. Image can now be exported as a .png |

simguy80 Thank you! As it turns out, I missed step 4 through 5 so thank you for explaining it to me.
