How do I rendering segments using existing LC and IR maps?

In using the Flythrough Wizard, I calculated LC and computed IR map from frame 100 to 200 into respective files then hit render. Everything processed fine. After seeing the final rendered footage, I needed to fix a mesh that was slightly floating above surface from frames 150 to 175. Using another computer, I loaded the LC and IR map into the flywiz and set an output file path. When I set frames 150-175 and hit render, the renders came out incorrect. Seems like the LC was not loaded so I get super black shadows.
So my question is, how can I render segments using already computed LC and IR maps of a sequence?
I want to be able to 1) Fix frames and 2) use multiple computers to render different segments of the sequence without having to render from the beginning. I.e. comp1 render 100-150, comp2 render 151-200, and so on..
Thanks.

hello, well first thing :
You cannot reuse LC and IM files if you've modified any geometry !
You need to recompute at least this part from scratch...
you can change frames directly into flywiz but i strongly suggest to truncate also your timeline to the desired frames.
It'a a vray limitation : whatever you say, the lightcache is computed for the active timeline.
you can of course make prepass 1 and 2 to generate im file and Lc file.
Then, you need to apply Sr settings (and also lights and materials optimisations - see init/save menu) to your scene and run the pass3 "by hand".
you need in this manual pass force IM and LC to "from file", pointing to your files.
ANOTHER (easier) method is to simply activate DR button to get this render boosted by DR slaves.
