Precalc irr maps in VRay

I'm rendering an animation using VRay. I previously did a precalculation and stored the irradiance map. I've been fine tunning some materials, specular reflections, dimming maps, color adjustments. These are all small changes and every time I render it loads the stored irradiance map.

 

Here comes the problem, I don't know why but suddenly, even the map is loaded VRay now goes all the way thru 4 prepasses. The last change I did was a material changed from Standard with a VRay map for reflection to a Vray Material. Since I saved the previous material I returned to that one but VRay is still doing all GI calculations again.

 

Any clue?

interpolation can save some time, but can also produce some ugly blurred reflections... if you can, I think you should avoid them.

 

you should read the latest tutorials on animations over at chaoticdimension... I think you can use the lightmap for calculating glossy relflections somehow.. havent tried it myself yet, but its supposed to be pretty fast.
