Quote - Unchecking "Shadow Catch Only" shouldn't affect any model in the scene.  It certainly doesn't on my P6, at least.

Are the lights actually casting shadows?  That's a totally different option from the Cast Shadows you selected in Render Settings, btw.  It's on the light parameters.

Also, if it's a big scene, Depth Mapped shadows (which you really shouldn't be using anyhow) will often refuse to render correctly, if at all.

In preview the shadow is there... but render it and there it is 'gone'....
In light parameters doing anything with that shadow setting just sees it re-set to its 1.000 default, not allowing me to do anything with it.

The mystery deepens
