Vray & Irradiance Map File question

[danb4026]

I thought that when you have saved an irradiance map and light cache file to use when rendering, it was supposed to make your render process faster.

 

I have found that, although, it does not have to recalculate those maps, if you have used the "incementally add to file" option, the file might become pretty complex, and make the rendering take a very very long time.

 

Is this the case, or am I doing something wrong???? Thanks for any advice,

This post will get moved over to the VRay forum, but what circumstance would lead you to use the 'incrementally add' option?

Where is the Vray Forum? I have 5 different camera angles within the same interior space. Although its one space, there are a number of angles and corners that I thought would negatively affect the lighting map, so I did a few maps. But now the reender takes forever.
