How can multiple lights be displayed in a scene

[Dong]

In my business, I want to show the lighting effect as shown in the picture.Unfortunately, at present the material can only accept 10 lights max(I need more than 50).
I can set the glowLayer and the billBoard to simulate halo effect.
but i cant't simulate the materials effected by the true light,especially the water...
can anyone help me?

Hello Dong!

So technically you will have to split the water into multiple meshes and then use includedOnlyMeshes property of the light to define which mesh should be lit by the given light (http://doc.babylonjs.com/babylon101/lights#choosing-meshes-to-light)

but the "excludeMeshes,includedOnlyMeshes" for light is also max to 10,when my lights more than 10,how can i decide which mesh will be lighted,and How did it look as though he was illuminated by real light

Maybe you can make a script which take object center position and try to find lights near this position, then deal with includedOnlyMeshes?

technically 10 is not the limit. If your material is simple you can even generate 16 lights (with material.maxSimultaneousLights property)

But as @V!nc3r mentioned, the best option is to limit the active lights per mesh

@Deltakosh
When material.maxSimultaneousLights  more than 10 , the shader will report an error as shown


@V!nc3r
Thank you for your response, but it helps with performance only, there is always a number bottleneck of 10.

I can't. I'll create another fake billBoard at the bottom  of each pole

Do you need realtime light positionning? 'cause if not, you can also use lightmap texture baking, and have infinite lights using raytracing render engine (in addition, you also gain realism).

@Dong: This is really dependent on the options you have in your materials. So perhaps in your case 10 is the max
