I can not figure out, why these spotlights on the right (Arrow) will not turn on. I move em around, change the angle start/End, Dist Start/End, and I do not get any results. I move them as well, thinking maybe the mesh has something to do with it..(I dunno). I am trying to get em to work like the ones on the left, that are pointing on the wall on right. I need those lights on the right to point at the wall on the left. But I need them to turn on, so I can adjust.

Does the wall on the left show up at all? Even with ordinary (infinite) lights? Sometimes Poser 6 will show a surface as black regardless of lighting. In that case, checking "Normals Forward" in the Material room for that wall will usually make it show up.

yeah..it does..I even moved the lights that are on the right..to the left side, and they still do not turn on.

Ok..I delete the lights on the left. Now the lights on the right turn on. What gives?

Try turning off the lights on the left, add a ball prop, then move it around the lights on the right until it shows up, so you know where they're pointing.

Oh wait, this only the preview, right? Will they show up when rendered? OpenGL cards have a hardware limit of how many lights they can use, my card for example limited to 8 lights. They will still be there when rendered. To see them all in the preview, switch to SreeD instead of OpenGL, SreeD doesn't have a limit for the number of lights.

My thoughts exactly, stewer. You will be hard pressed to find an OpenGL preview with more than 8 lights.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.

Just for fun, I tried building a similar setup in P6. It seems to work OK, so I don't think you're running into a natural limit on number of opposing spotlights or whatever. Above is preview, below is render.

Hm. Guess my picture proves the point about the Open GL, doesn't it? (I'm so accustomed to lights not showing up correctly in preview that I didn't even see it as a problem....)

I do have it on SreeD. I guess my limit is 9 lights. And I have a total of 14 spotlights. I see them working now, after a render. Since I am not able to see the lights on the right in the preview. Positioning em, isn't going to be easy, even when using the shadow cam. I like how the lighting is shown on the roof (Top right). Trying to get it the same on Top left. Oh..I also like to use atmosphere (Volumetric lighting). I decided only to use 2 (Lower front) to give the dusty air look. Any suggestions?

Ah..thats ok for the Volumetric lighting. I had to refresh my mind. I got it together. Will show a render when done.

Did a render using the Volumetric lighting. Here is my results for now. Still adjusting.

It looks great so far.

Lookin' good, Robo! I do feel like the bright area on the floor in front of the mech makes it look a little like it's floating, but that's my only real complaint.
