Alpha Channel Plane Objects & AO
Hello Creative Cow Gurus,
I am working on a logo animation and am running into a problem with AO and objects created using planes and alpha channel. I have a few planes that have alpha channel materials applied to them creating the faces of my objects, and than I have an extrude nurbs object sandwiched in between the faces to give it some depth. I am trying to achieve the look of the logo simply sitting on a backdrop with nice AO shadowing underneath the logo.
The problem is the AO/lights are seeing all my alpha channel objects (planes with alpha material) as plane objects still. Is there a way to have the alpha channel information also cast the same type of shadowing?

is it possible to simplify? Why are you using planes with image/alphas with an extrude underneath and not just applying the image to the face of the extrude?

Brian,
I could do that for a few of them…don’t know why I didn’t think of that. But, there is one object that I don’t know how to build in 3d. It is an intricate filigree type .ai background that I wanted to be able to animate. However, the paths are way to intricate to create any type of extrude nurbs from it. So I went with a plane and an alpha material. Is there a way to make it easier on myself? For the quick fix i put the filigree in the background image. I can’t animate it but I’m not getting my shadowing problems there.

Do you have to use AO? You should be able to get a similar effect using multiple lights with soft and/or area shadows.

Thanks guys,
I ended up taking off the scene AO and using mainly more lighting and a soft AO on the background image. It turned out nicely. Still couldn’t get the filigree modeled as an object in C4D. It’s really just thin lines so I’m not sure how I would have done that. Anyways, on to another project. Thanks guys.
