Hello,
I’m using BlendMode.ADD on a bunch of small sprites with transparent sections. The sprites contain bitmapdata. When I have a lot of them piled up on top of each other they start turning black. Any ideas on why that would happen? It seems like the black parts only occur in the transparent sections where either alpha is 0 or very near 0. Seems strange that ADD would somehow add up to a black pixel? Makes no sense as the docs only said it was clamped at 0xFF.
Someone had suggested there was a similar issue with flash a while ago and to add a blurfilter with certain settings to help restore alpha values, but that didn’t seem to help.
Here is an image of the issue (with various blur filters applied, bottom is with no filters):
Thanks!
