Thanks Adam and Brian,
So, here’s what I did. I turned off the editor display for the environment, and turned off OpenGL. Then I put in the environment, and checked fog, and everything seems to be fine. I was able to mess around with the fog parameters, and it seems good now. So I guess it has something to do with the editor display/openGL aspect.
I have no plugins installed yet, as I haven’t had time to put them in after re-installing Cinema, so I think they can be ruled out. My graphics card is a RadeonX1900. I’ve been thinking about getting a better one, so maybe that would help matters. But it looks like I’m good for now anyway. I’ll post again if something happens.
thanks for your help,
Jack
