Keyframe Photon Intensity

[burleik]

I have searched and found some abandoned threads explaining how to key frame photon intensity.  I still don't get it.

I am using MAYA 15. 

When using mental ray and an area light emitting photons, I would like to grow the light intensity from 0 to something close to regular lighting.

I have a dialectic material, caustics, and final gather in the scene.

My goal is to keyframe either photon intensity or the light intensity using maya/mental ray.

Can some one help?

Thanks in advance.

Hi,

I think you can use a specific layer overriding photon option in your Render settings, then create different Render pass contribution maps inside, overriding photon intensity in each of it, or something like that...
