a simple alpha question 2004-03-04 - By alex dinnin
Back
I'm sorry I am really going back to basics here... but I am pulling my hair out
trying to crack it... and I have failed !!!
Below is a simple script, I have made two spheres a small one and a big one
for reflections
I have plugged a checker texture in to control the transparancy !!!
why can I see reflections and specular where there should be clean holes ??????
Please HELP
ALEX
