Hi all,
I'm stuck with an alpha layer problem. Tried everything, no solution in sight. It looks like artifacts are generated inside Paint.net when editing and pop thru the alpha layer. Is this a bug or bad editing on my part???
Here are the details:
I'm making DDS files for a car racing game to "paint" numbers and sponsors on the car.
Here's what I do
1-Draw numbers / sponsors over a "transparent" background (which it isn't really as the alpha isn't set yet)
2-create a mask layer (pure white background + black silhouette of image of step 1)
3-Apply mask with the Mask plugin (inverted to keep the "painted" areas)
4-Export DDS to game (or PNG, same result)
What I get are black boxes around areas where I had numbers etc... on the car. I tried exporting to DDS with GIMP, same effect. (not related to DDS plugin). Suspected something with the game engine, but no.
What I found using the alpha mask plugin by unchecking the "invert mask" button is that the black box are indeed hidden within the original image. Even though I never "painted" them.
Nothing shows in PDN on the final image (when I apply the mask correctly as intended), but the black box are still there somehow and make the image unusable in-game.
Even the color dropper doesn't "see" anything, all transparent area are picked up as alpha =0.
Only thing I could think of, is that the artifacts boxes look exactly like the selection box I used to edit and place my design elements (numbers, etc..) at step number 1. It sounds crazy but I have no other explanation.
Does anyone have a workaround suggestion? I did try to do the masking operation with GIMP, but I get exactly the same results. Seems really embeded in the "step 1" image.
