i have some prob with noise on light is there someone knowing how to do ?
Increase the intensity of the light (more watt). Or add lights, Or add environmental lights.
You can also increase render samples. For some projects 100 is enough. And for others you need 4000 samples. But it increases render time.
You can also go de-noising options in Blender. Or change textures.
There is no quick trick. It all depends on the above factors.
And if you are using Cycles, then switch to Eevee.
