irradiance map:how to do it

[smr_VIZ]

What is the right procedure to do save the irradiance map and reuse it next time?

 

I heard this will will save a lot of time, how good is it?

 

Thanks.

calc the irr map, save to file, then click from file, load the saved map, and hey presto you're in business.

 

it's very useful for animations, or multiple renderings of similar camera views, but less so if you're changing any elements of the scene in the future, you'll probably need to reset and re-calc for that.
