Hi back again as unable to render again getting the red cross. No trees, few more objects in there and was rendering find last night. Have removed the paintings I had made as I thought the high res jpeg textures might have caused it to no avail.
I have tried rendering just a close up of the floor hoping that the other objects not in the room would be ignored to no avail.

These are some of the renders from the file.


Been working on the lights for this one and patience got the better of me as it would take hours and then bomb on me when rendering it, must be the cars and the reflections ?
