Getting rid of white lines along seams and borders

Hi there. I've been plagued by this problem. When I make an outfit it looks great up close, but when you pan back, white seams become visible. Is this the "halo" problem? At first I thought it was due to cutting into the bleed area with the alpha channel, but I'm reasonably certain this is not the case. Can you direct me to a thread or tutorial that deals with this?

I think it is SL aliasing the pixels to nearest neighbours. Try expanding the outfit pixels outside the seams more instead of roughly cutting it out.

Or don't cut it out at all. Fill the layer you have your "fabric" texture on completely. Then let the alpha channel image do its job, which is to separate transparent from opaque areas. If you rely on the alpha channel to do the "cutting" for you instead of cutting things out in layers, you'll avoid the white halo problem entirely.

The white halo occurs when boundaries between white and black in your alpha channel image occur in places where there are no neighboring pixels in any of your layers. Trying to avoid the halo, people use all sorts of tricks to put pixels in those troublesome areas -- smuding the edges of cutout fabric, applying a Flaming Pear plug-in, adding a dark layer at the bottom of the layer stack -- but there's no need. If you don't cut holes in fabric layers in the first place, you won't have to fill them in later.

Thanks for the advice. I will try it out and provide feedback on the results. I do not cut the fabric at all though, I let the alpha "do its job" so to speak.

I have to agree with the OP as I've also been experiencing the same problem lately and use no transparent areas when constructing clothing. I think it's more of another bug rather than our creations themselves, since the grid has been acting up quite a bit these past few days and I've never experienced that problem before.

In fact, I've lost all slider capability (except for pants) in the appearance window and for some reason my avi's head skin now has a darker tone than the upper and lower skin textures. Also, a few friends have been losing a lot of inventory and report other weird happenings. o.O

Ah, well, the loss of slider capability in Appearance is probably the palletized texture problem that seems to be an issue for people with NVidia graphics cards in their computers, like me. Solve that one by going to Advanced >> Rendering >> Features >> Palletized Textures and turning it off (or just typing Ctrl-Alt-F7), and then doing a rebake (Advanced >> Character >> Rebake or Ctrl-Alt-R).

There are interesting random surprises in SL, but that's an easy (although annoying) one to deal with. BTW, the solution is not persistent. You have to do at least once in every logon session.

Alright I made another bodice and pants making the edges as large as possible without touching the other body parts in the template. This seems to have fixed the problem on the seams at the sides. However, I'm still getting a hairline seam where the bodice meets the pants (photo attached). Since the bodice (upper) is sleeveless, I can only extend it on the template as far as the arms...so its as low as it can get. And the pants template I bring the texture all the way to the top of the TGA. I suppose I can work around this by making it a jacket and adding some length. It doesn't seem like I should have to to that.

I have made the TGAs available if anyone wants to see what they look like. They are placed at http://slurl.com/secondlife/AngelGate/216/60/21.

The seam between the shirt/undershirt and pants/underpants layers is an SL glitch. You can get rid of it by using the jacket layer. No need to do any extra work. Either put a clear texture or your pants texture on the bottom half of the jacket layer.

Yep, that fixed the slider and skin tone issue, so thanks Rolig! =)
