Hi,
I am getting errors when I have more than 10 lights in my scene. Am I doing anything wrong?
Thanks in advance.
Have you read about the light limitations? Lights - Babylon.js Documentation
Yes.
As per the documentation,
- You can have any number of lights.
- You can even set material.maxSimultaneousLights
So, the problem is somewhere else.
can you repro in the playground?
I will try.
Here is the error

This is the playground Babylon.js Playground
Here is a playground with lights https://www.babylonjs-playground.com/#IRVAX#0
This is some information on using the playground https://doc.babylonjs.com/babylon101/first#the-playground
Deltakosh is asking can you put some code in the playground and reproduce the problem.
Yeah I got it.
I am getting errors if I set material.maxSimultaneousLights to a value greater than 10.
Here is the PG:
https://www.babylonjs-playground.com/#IRVAX#67
Seems OK https://www.babylonjs-playground.com/#IRVAX#68
Can you put the code you are using in a playground.
Sorry you are right perhaps @Deltakosh can help
Unfortunately you are hitting a constraint of WebGL2 itself:
The best option could be to disable uniform buffers (it will give you more room but the rendering could be a bit slower):
