I recently starte getting massive artifact when viedw or rendering tree in iclone 6 where it wasn't doing it earlier. Here is a partial render

and it the full video render earlier (ithink iClone 5)

This only happens in videos with trees (i'm using the 2014 total blant bundle)
I have an nvidia gforce 970 runing in an aliein ware Area 51 computer. I have treid reinstalling the video drives but nothing changed.
Any ideas,

Think I solved it myself. I checked out some of the default  ic6 project with trees and they seemed to run fine.  So I removed all the tree and used some trees from the iC6 Botanical Samplers pack and they worked fine (no artifacts at all). Don't really understand why it changed relatively recently. It had seem to be working ok in IC6 (minimal artifacts) and only seemed to go to unusable with a recent video card update (not an iclone update). I guess I will have to us only  ic6 trees, but that means sceens I bought that have the older trees  (LivePlants - World Wilderness Volume1) are now unusable in Iclone 6.

I had major artifacts with one of the latest NVidia drivers (378.49) and I had to revert to 376.33. I see that there is a later one 378.66. Is that what you're using?

As to the trees, I have also seen that older SpeedTrees give problems.

378.66 was worse that 378.49. 376.33 seems to be the best one to use at the moment.

The problem is that I think I have been getting tree artifacts with Iclone 6. It wasn't bad and didn't appear to show up in render. Since I went to ic6 it always looked like something was moving on highly treed scenes even though I was not playing the animation.  The changes in the video drives has made it unusable but I really don't like using old drives especially using subsequent releases seems to make it worse. It appears to be something the way iclone 6 does the old trees.  As I said if I use the new trees in the sampler I don't get any artifacts.
