View Full Version : Ambient Occlusion for Animation ?

04 April 2006, 02:44 PM
Hi all,

I'm just trying to use the mi_ambient occlusion shader for the first time...
Just wondered if it's any good for animation ... do you need to "Freeze" it like
Final Gathering ?? or is it just like a texture that stay the same on every frame ...
Just asking if they might be some flickering problems ...

Thanks !

Try "baking" your AO calculations

I'm not really an expert in baking anything ... I tried a few times and it seems way to complex for me ... unless you can explain how to do it ? Is there any way to bake a whole scene in 1 click ? or is too much to ask for ?

thanks for the reply anyway ...

Baking would help for sets that won't move through the time. If you have say a character jumping in a room, and you have a lot of shots and frames to render then it would very interesting to setup a way to bake the AO into textures using the baking technique suggested in Maya with Mental Ray. It will take a hug amount of time to finish comparing with rendering a signle frame. It's only worth of you have too much frames to render, otherwise, just render directly an AO pass.
Check the Doc how to bake lighting.
