| I've noticed if the center of a sprite is off the screen it appears faded or "alpha" Is there a way to prevent this from happening? Thanks! |

| I have never noticed that happening, and i don't think that is supposed to happen. Can you test this in a simple piece of code, where you just position the centre of a sprite off screen, and that'sit. Does it still happen? |

| I noticed that the other day when I was just messing around with code. I thought it was a lighting problem at first but now I think it is some kind of DX7 bug.. ? it even happens when I set the entityfx to full bright |
| ||
| I've noticed when other entities move into the sprite in just the right way, it also happens, not to sure. |
| ||
| I figured out what the problem was, thought I'd post this for future reference if anyone comes across a similar issue.. I had an alpha textured sprite on top of another alpha'd entity, for some reason the alpha textured sprite become "extra alpha'd" in certain areas |

| Yeah, the old 'alpha on top of alpha problem'. I once had an alph'd river and alpha'd treeleaves in the same scene which caused the alpha'd river to visually 'punch' through the river bank. Yuk - messy. I took the alpha off the treeleaves and the problem ceased. Also, with alpha'd trees the back leaves can often show through the front leaves. One thing I would like for any B3D update would be proper alpha-sorting. - Mark? |
