Hi all,

I have made a sprite in Photoshop for a window of this house that I'm building in WED.

The image is in BMP and has black areas (which will be transparent in WED) and has colored areas for the rest. My problem is that around my colored areas, there is a black border that WED doesn't take out and that instead should be transparent.

For clarification, WED makes most of the black in the image transparent and works correctly, but leaves all this black lines around my colored areas and looks weird.

Is there a way to take out the black borders around the non-transparent areas?

Thank you.

Two ways to do it:

1. Use a TGA file with alpha channel in it to replace it.
2. Set the nofilter flag on to prevent the smoothing effect.

These are the only ways I know of.

crazycoder, after converting your bmps to tgas or dds with alpha (yes, forget about bmp and pcx) take a look at WIKI (alpha test sample). That code may save your time.

Read the manual about the d3d_alphatransparency variable: this is the normal solution. You'll need a different color than black for the background, then. Another solution is the mentioned sprite effect on the Wiki.

While TGA files with alpha channels, or the nofilter flag would solve this problem too, they are not recommended due to their disadvantages.
