we’ve known about alpha testing for a while [I belive wiseman303 was the first to write a script to do it]
it only works in blender
and since blender had the redraw and logic tics seperated the flicker has been around
it messes with all things with alpha channels, and it would be a nice feature to have in blender [it allows higher poly grass or trees without the overdraw hit]

https://blenderartists.org/forum/viewtopic.php?t=39193 [it is noted that in 2.36 it doesn’t work right]
incredible :o
Works fine (2.36 winXP Radeon x300).
Wow… is it turning of the mipmapping? I’ve wanted something that would let me turn off individual mipmaps for a while.
It turns on alpha testing by using the Blender.BGL module in Python. It’s similar to the alpha testing script on my site, and like my script, it won’t work if the game is saved as an executable.
Nice work Doc Holiday, that’s an interesting use for alpha testing.
