I have tried to render the dia effect in carrara 7 express. And ? Yes, in this program it works. But the result is greycolored !

1. I have placed a spot lightsource.
2. I have placed a rectangle object in front of it. Textured with a picture and transparency.
3. I have placed a second retangle behind the first. Only white color.

In poser 7 i see nothing on the second retangle. In carrara 7 express can i see a greycolored and zommed picture. Like a real dia. Now i must find a way to transport the color to in carrara !
