Cool.

I was wondering: how does your system compare to speedtree in rendering speed?

Since you are doing something similar to speedtree (except the dithering) and speedtree is implemented in engine, shouldn't speedtree be faster?

Right, just for ultra.

Yes, it's fixed now.

Now I have noticed another bug: the billboards never really disappear even at close range.

On still images is not very visible, but on movement it is.


Enhancened to show the bug more clearly:



Yes, that's correct: setting the billboard to GREAT fixes the transparency bug.

I suppose it's a problem with the BLIT function of the post process and some rounding being done differently on different hardware.

I program shaders myself, once you find the fix, could you tell me so I can avoid it in the future too?
