Funny fog problem

[joethelion]

Hi there,

I suspect I`m doing some very simple mistake but I have trouble using fog. When any object around the object with fog is not grouped, fog doesn`t function and the object comes out completely transparent. When everything else is grouped fog is OK as it should be. Camera options or any other setting including color multiplier don`t have any effect on this as well.

Many thanks !

Problem solved. I don`t know why the other objects being grouped or not affects the situation but it seems in order for fog to work, it has to be grouped (like with displacement).

We require that the entire surface that will have any sort of volume related attributes affected be grouped, because SketchUp can't keep track of that information itself very well. The group gives us an extra level of organization that allows us to process the scene more quickly, and more accurately.
