Point light maximum?

[Marleys Ghost]

Is there a maximum to the number of point lights that can be used in a scene ?

As many as your memory and FPS allows. Probably over 3000 on any machine, if they are not all in the same place.

3000? M'kay .. I have a very basic indoor scene, with 8 P-lights, and using Flip() I get a steady 60 UPS (fluctuates between 59.999xxxx and 60), if I add another single P-light, the UPS drops to between 3-5

Ok, cancel that, I think I have solved it, the P-Lights where set to Static + Dynamic + Buffered, changing that to just Static + Dynamic for all the lights has thus far cleared that issue up (well I have 11 P-lights now and the problems not arisen thus far lol).

Lights with shadows are exponentially more expensive to render than lights without. This is especially true for lights with multiple shadow maps (e.g. point lights and dir lights).

It depends on a lot of things. What's moving through the scene? How often do lights get their shadows redrawn? 2.31 has a lot of new features that you can adjust to optimize lights based on how you expect them to behave.

Not a lot moving, a few security cams, and the camera in FP. some crates and a few barrels, a couple of doors all of which only move when "moved". Not had a chance yet to add more "stuff" but will test later on but switching the P-Lights from Static + Dynamic + Buffered to just Static + Dynamic with a 512 shadow map seems to have worked thus far.

SetLightRange(light,1) makes also a big speed improvement.

I have 300 point lights with default range (=15), and 35 FPS (they overlap multiple times, since their distance is 1).

When I change the light range to 1, I get 242 FPS.

[Marleys Ghost]

since their distance is 1

 

 

1 or 15? and the range of the light default was 10 which I set to 5 and tried to space them so they did not overlap.

[Canardia]

1 and 15. 1 is the distance, 15 is the range.

If each of those security cameras is performing another render, I hope you are using EntityCulled() to only update them when the corresponding screen is in view, and use occlusion culling on the screen mesh!

well in the editor, a P-light has range 10 default, for distance do you mean view distance?

 

@ Josh: renders only take place when required.

[Canardia]

No, the distance between each light.

ok, am with you now, I guess the liquid lunch was not helping.
