Weird outline with Clear Prims

I'm working on a skirt and the bottom of the prim is translucent. For some reason there a weird black outline on the base of the prims even though all sides or translucent. Here's a pic to show you cause I don't know if I'm explaining this well enough.

I know there's a way to fix it I just don't know how. Thanks!

Great googly moogly. Smaller image size next time!

Anyways, its a couple of little texturing quirks combined... easiest fix is to leave a couple of pixels of empty space around your alphas before importing. Or scale up the texture about 2% in SL. Your basically getting bleed-around from the other side of the image.

Hi Apple!

If the bottom is truly 100% transparent, then I suggest you move the texture vertically to see if that helps (may be caused by some bleed from the black on the top of the front face).

Also try changing the vertical repeats.

Best,

SL tiles all textures, even if it is set to a repeat of 1.000 in both directions. The result is that a texture that is opaque on one edge and transparent (alpha textured) on the other edge will have a 1-pixel dark smudge on the transparent edge. This is to match up with the pixels on the opposite edge, if tiloed. The easiest solution is to set the repeats in that direction to 0.990.

hello i was having same trouble when making a fire texture.

try this:

instead of setting sizes for 1.0 and 1.0 try reducing to 0.9 on both. what i found was happening was the edge that had the visible part was bleeding over slightly to the opposite side where i wanted clear. THIS DROVE ME CRAZY!!!!!

any how this trick worked for me and now i dont have that line anymore.GOOD LUCK!

Something else I have noticed when making alpha channels in photoshop is that if you're not careful and fill the space with the fill tool, even if you do not have feathering or airbrush on, sometimes around the transparent parts at the bottom of your alpha channel you will get a 1 or 2 pixel grey edge that will also produce this line. Dunno why, just something to be aware of when making transparent textures. I would also ensure to change the texture on the bottom of your skirt prims to a transparent one before you make them too thin to do so.

Go to this page:

http://www.flamingpear.com/download.html

And download the "Free Plugins" collection about two thirds of the way down the page. Its a dozen or so plugins, they work with Photoshop or Paintshop, but the one of interest is called Solidify B. Once your done with your image, merge all the visible parts into one layer and run Solidify B on it before exporting to .tga. Fixes this problem nicely.
