I’m trying to use a blend file from the Blender Greenhouse, but I’m running into a problem with alpha textures. Although the texture looks OK in its little preview area, when I do a real render, there’s a white, jagged border around the texture. Here’s the blend file:

Just hit F12 and you’ll see what I mean. Anyone know how to fix this?
Hi,
click the “premul” button in the texture buttons (F6)
Greetings,
Peter
Thanks for the suggestion, but that doesn’t seem to fix it, at least not on my computer. Does that work for anyone else?
In the Texture Map To panel select Stencil.

go into the texture settings for every texture-picture,
thats the material-settings last little subwindow in the long row,
the menu “Map to”, where you set the “color” and “alpha” switches with click
and there is the button “Stencil”. Activate this too and look that the white,
highlited border disappears. I dont know when and why this is necessary,
the reason may be the setting for the default color of this material. That is
“white” even so the transparancy is on 100%, it still is visible at those alpha-mask-borders.
You can check this, if you set the default color for the material to RED, then the white-borders will become red.
Setting “Stencil” seems to fix this … dont know since when… or if this was always the way, because using only a texture (as texface) does show the borders too …
edit: oops … Mark was quicker … while i was typing and looking for … since when a this effect shows …
Richard, test-dr, thank you both very much! The solution works. Richard, I appreciate the image. And test-dr, thanks for the explanation!
