tjohn has a point, the image runs off the square, try fixing that. If that doesn't work, and you are still convinced that the image just isn't going completely transparent, thenwhat you can do is go into a picture editor. let's say... even the basic windows paint program will do. paste the image, and then with the eyedropper tool thingy... put the cursor over a section without the white in it. a supposedly completely black prtion of the picture. copy the color of the pixel you have chosen. then open a new paint document, create a square, then paste the color onto it. then save it. when you go back into bryce, create a really big square, and cover your entire scene with it. in the materials editor, give it the copied color texture that you have created, and apply the same alpha stuff, transparency stuff... whatever, to it as you did for the picture. then when it is ready and seems to be just as transparent as the original picture, put the original picture square in the foreground of your scene, so that it is in front of your enormously big square. that way, where the transparent line of the original picture fails to disappear, the big square willcover up for it. *phew that was a long tutorial.... or you can take the original picture, put it into the paint program, and make a bigger square around it. that is the same color as the black parts of the original picture, and then apply that texture to one big square *i know, i know, i should've said that last tutorial in the first place, but i was way too lazy to erase the first one
