Default Shadows and transparency...

Hello everybody...

Probably it's a stupid question but..:

I would like to make an object appear and disappear animating its material's transparency. The problem is that the object casts shadows even if it is totally invisible. I would like the shadow to appear with the object.

How do I do that?

Thank you in advance.

That's one of the limitations of depth map shadows. Set your lights and render globals to use raytracing, instead. You'll have to play with the material attributes a bit to get what you want (especially if you're using something other than a lambert) because even if you make the object transparent, reflections and whatnot will still cause shadows. Also read up on an attribute called "shadow attenuation."
