http://www.renderosity.com/messages.ez?ForumID=12356&Form.ShowMessage=891170 I'm sure its an easy fix. It definitly looks like scene saving is writing two lines in the doc section. The CUSTOMRENDER displayMode line is cause rerendering of scenes. I haven't tried just forcing it to normal with changing the display mode which I'm sure would work but it fires off a render as soon as the scene loads. Thanks
