I seem to have same problem with some of my populations in beta too. Its currently rendering at home, ill hop on once back and upload a picture of the issue areas. It just seems to not realize it should be rendering part of a plant or something in certain areas.
ok, back home. image is almost done. just as a note, i tried a 1920x1200, and then bumped it down after first render failed due to memory, then i borrowed 4 more gigs of ram from a friend (brining my total to 8gigs... and making sure tg2 had the full 4 gigs to it as im in 64bit vista).
Anyways, noticed a few population errors (along with some errors of my own that i plan to fix next render because ive noticed some things wrong with it. Heres the image with the errors with the render that i think are render side. Some might just be the models, but it seems too odd to be the models, as often they are exact right angles. The models are all thanks to lightning, except the tree stump which i plan to replace later as its a holder stump i had in objects from someone on forum but i dont know who so sorry but technically their credit.
Another thing ive noticed: the timer has just stopped dead at 8:14:11s. But it keeps updating with more of the image. Its definitely been over 12 hours now, the timer must've killed itself 4 hours ago? Also the image seems to be updating in huge chunks quickly, then nothing for a long time. Before if you watched you could slowly see it add more pixel by pixel.
also the render appears done, but its still waiting.... dont know what on. terragen is using 0 processor, but ~3.4 gigs of ram.
*sorry for the artifacts in the picture from compressing, but you can still somewhat see what im talking about in the circled regions*
