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?
