Achieving realistic reflections and light distribution onto the road from a source (LED) via vehicle headlamp reflector.

venkatesh.gothe — Thu, 30 Dec 2021 12:36:10 GMT

I am interested in studying the light distribution/profiling onto the road from a headlamp for low and high beams.

Struggling with getting the source light being properly reflected via the reflector onto my geometry/plane.

Any suggestions on how to go about this please?

You will probably need to use raytracing with photon mapping and caustics. But it is quite difficult to give any tips without knowing the exact setup.

Hi @michael_nikelsky .Thanks for the suggestion. It really helps. Though as you can see in the screenshots attached the problem with the projections is improper reflections and low intensity onto the ground. I have tried varying the intensities, ray files (5M), reflector material but still in vain!
