Hello, Question.. I am working on converting some items in my game to 2D Sprite representations, since it is a puzzle game which does not move in the 3rd dimension or Y anyways. What I need to know is, I am going to be doing screen captures, and cutting the images to 64x64 either PNG or TGA files, and I need to know how to make the background portion of the images transparent, is there a special color that Blitz3D uses, is it black 0,0,0 or magic pink 255,255,0 or what ? Can someone please help me on this, also if it helps I will be using nSprite to do the display of the 2D images, if that info helps at all. Thanks..

You could copy whatever you need into an image. Then set the images mask colour: MaskImage image,RED,GREEN,BLUE That should work.

I would probably be easiest to use the alpha channel of one of the mentioned formats.

I have a problem using the Alpha Chan for Trans... sometimes (and I have no idea why) it looks grey. I use PSP8 to do the conversion. Athlon 64 3200 1024 ATI9000

Do you remember to load the texture with alpha channel? Check the docs, if you do, remember to enable the colour flag also.
