These pictures illustrate a problem I am having with Maya 5’s ray traced shadows using transparency.
The first picture shows the fully opaque ‘hair’ (no transparency) working as I would expect.
The second picture shows what happens when I assign a transparency map to it - the shadow almost completely disappears.
The third picture shows the shadow object with ‘primary visibility’ turned off but ‘cast shadow’ is still turned on, you can see clearly that the shadow is barely showing up, although more appears at the top of the head - the area at the back of the head should be completely black.
The fourth picture shows the head model with no shadow object for reference.
So I’m wondering how to get the hair shadow object to cast a shadow as seen in the first image. Is this a bug in Maya or am I doing something wrong?
