hi, in cartography shop you know you can get a certain color to be transparent in a 3d objects texture, how would you do this in darkbasic pro. I have tried the set image color key command but i can't get it working, the bit which should be transparent then becomes black.

p.s i did set the image color key before i loaded the images, and the rgb values are correct.

thanks for any help,

you can just use black on the object and set the objects transparency on, that works ok, or you can set a rgb value with the
set image colorkey command, then make an image with that rgb value for the transparent bits, it should work, I can only assume you either have saved the image at a different bitdepth (eg 16 bit) OR you saved the image as JPG, JPG is a lossy compression system that creates something that LOOKS like the image you had, but that section of colour will be messed up and may be quite a way off from what it was saved as, the rule is DONT USE JPG FOR TEXTURES, all you do is save a little disk space since they get converted back to bitmaps internaly anyway when they are loaded, except that a converted JPG is a corrupted bitmap and will bear little relation to the original (on a detailed level that is), and that would mess up the colourkey.

Thanks, i learnt alot from your explanation and you solved my problem in one go thanks again!

You could also use a texture format that contains an alpha layer too, such as PNG and TGA - both are non-lossy formats.
