that would be good to know all the rendering parameters, coz all can be a fact of excessive time.

Re: Is Saving Irradiance Map Helps Lower Rendering Time?
If you are using Vray then yes! The irradiance map is essential to save. If you ever need to re-render at a different resolution, or if you need to fis/replace something in the image, then saving the irradiance map can save so much time.
Depending on the complexity of the scene, the lighting calculation can take a significant amount of time, also depending on the quality of the lighting calculation ie, very low, low, medium, etc. Having to re render and then do a light calc again is time wasted. You can either save the Irradiance Map automatically or manually. If I do it manually, I have to save it right away. If I start doing some other things after it's calculated I lose the lighting information for some reason.... Hope this helps! Adam |
