#Transparent?
3 messages in this thread
Hi,
how do I make an object transparent? For example, if I make a glass object and
puts it a little above a table and then lights it with a spot from directly
above (with shadows on). The glass object creates a black shadow on the table.
WHY? I did put a transparent material an it (glass).
Thank You/Joakim
Joakim <<glass object creates a black shadow>> You will have to some reading on
this, but here's the general point. Your spotlight is creating a bit mapped
shadow. If you want the spotlight to "see" the transparency of the object and
thus throw a shadow that demonstrates the transparency of your object you have
to turn on RAYTRACE in that spotlight. Note that raytraced takes much longer
render time. So, when I need a raytraced spot I create one dedicated to the few
objects it is designed for, exclude all other objects from it in the scene and
attenuate it so it's area is restricted to exactly where I need it. Note
however that you will not get true raytracing, colors etc… just the transp.
quality. If you have the book 3-D Studio Special Effects there is a great
chapter on faking true raytrace. The chapter is by Tim Forcade and very
helpful. Anyway, as you mull through all this, go directly to your 3-DS Users
Guide and Tutorials. The basic concepts are very important to fully understand.

Thanks Jeffrey,
I`m digging through Inside 3D-Studio R4. That is interesting reading.
Thanks for your advice/Joakim
