I am going crazy with it (beneath other things…)
I want to make a multiple material.
Give a circle a multiple material as usual.
Two materials are now assigned to the faces of the circle.
The first one is - say - blue, the second material is red.
Now reduce in the second material’s buttons window the A slider to 0. In the in rendering (F12) the whole object dissapears. But shouldn’t it be blue?
This is only an example, in reality the multiple material is much more complex.
So what am i doing wrong?
