Has anyone seen this before? I built this project and when I went to do a test, found out it won't even render an empty Daylight Environment.

assuming that you are working with c4d... it could be that there is a c4d physical sky object active that blocks the octane environment

Thanks for your reply, bepeg4d. I will check. Based on what you suggested I think I MIGHT know what it is. I had a light source object that did not export from C4D to OBJ, but I never gave it any light source qualities...just default material. I will look at that, but as far as any other things in the C4D project like a sky object, I never added one...Not that I didn't brain fart while building the project. . It is very late and I need to get to bed, but will check in the morning.

Before I head off to bed, I did notice that in C4D, I made the light source object as a 2D plane. Which brings up the question...Can Octane deal with a 2D surface, or must the object always be 3D volumetric?

..it should be ok =) i mostly use planes as emiters, work just fine!

2D planes as light emitters are fine. Just make sure that the normals are pointing in the direction that you want the light to point.

OK...Looks like it was a corrupt C4D build. I had 41 pushbutton lamps that were very tiny. When I increased their size and rebuilt the file, everything worked out OK. Makes me wonder if this is another one of those scaling artifacts, maybe not too different from the black "bed bugs" problem I had about a month ago.

Thanks, everyone for the replies. So I also know now that 2D surfaces are no problem in Octane.
