Thank you beanzvision
Yes, you are right, although i never got that warning i should do that and reduce the detailed trees in background.
Just one more question. in the test you have made, there is a car that is almost transparent, do you know that is happening?
I tried to ask to maxon, but i still haven't any answer.
That only happens to me when i use Team Render and my scene file is saved on the server. If i save the project with assets to my desktop and render from there with TR, works fine.
Thanks again
