It's not this particular scene. It happens in another scene as well.
It happens in almost all the scenes at random.
Changing the 2sided material worked at first, but as soon as I added another grass chunk that uses the same material as the previous grass it got stuck again.
In another scene where there's only 1 MS grass object on a plane it happens again as soon as I use more then one scattering object inside MS.
Even if I make 3 separate MS object for each chunk of grass it gets stuck.
I found out that if I switch off the tree layers. Explicitly the pine trees, it somehow renders fine, even if the trees are located behind the camera and not casting any shadow on the grass.
The trees have opacity mapped leaves but I'm not sure if it has anything to do with this problem.
It's a serious problem because it seems it happens randomly.
With vray 2.4 everything works like a charm even if I pump the MS objects to few millions.
Vray 3.003 Lightcache stuck on 99%
Re: Vray 3.003 Lightcache stuck on 99%
Well, it has nothing to do with the trees as well.
It is somehow related to the amount of maps/bitmaps used, or the bitmaps size.
If i put an override material to everything else but the grass and trees. It renders fine.
If I leave all the materials and hide the trees, it renders fine.
If I use only 1 type of grass chunk it renders fine.
But if try to render it all together it gets stuck on the LC calculation.
I'm clueless. I'll try to bring it over to the V-ray forums as well.

Re: Vray 3.003 Lightcache stuck on 99%
after looking at the second file
we can confirm that Light cache in Vray 3 does not work correctly with Vray2SidedMtl
looks like this need to be reported to Vray support
we will submit this to them, after having some more tests done
anyway we always recommend using Brute force instead of Light Cache for Secondary Engine
in exterior visualization with lots of geometries

looks like this will be fixed in next V-Ray update

Hi, all.
The current Vray is 3.00.06.
Was this problem fixed? Light Cashe works fine with the latest Vray?
Or, should we still avoid using LC expecially with Vray 3.0 and Multiscatter as mentioned on
https://forum.icube3d.com/viewtopic.php?f=16&t=588
?
I am looking when I should switch to Vray 3.0.
Thanks,
The current Vray is 3.00.06.

we only recommend avoiding it unless you are experienced V-Ray user, this applies to all V-Ray versions
