Quote - many of the hr2 props I use are transparent, and once posed, untill rendered, I cannot see (how) they are posing.

Go to the material room and turn off the transparency for the item. This way you can see what the hair is doing. Before you render, go to the material room and put the transparency back to what it was. That's what i do now when I'm working with hair or clothing that I can't "see" after applying a mat texture to it.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
