Pot light ref

Hi, I'm new to this forum and have been using blender for a few months now.

I'm trying to get this double cone appearance with the pot lights I've set up. I've tried various things like double light sources and even a emitter. But I just can't get this focused lens appearance.

If there's a way to add a b/w ringlike mask to the light source, I haven't figured it out yet. And I'd like to avoid needed multiple lamps per Potlight if possible.

Does anyone have a straight forward solution for this?

Thanks in advance

If you're using Cycles, a straightforward solution is to use an IES texture in point lights.

Download a suitable IES file, 'Use Nodes' in a point light's shader, and plug an IES Texture node into its emission strength, referencing the file:

Strictly speaking, your model should be to scale.

Those are called IES profiles https://docs.blender.org/manual/en/latest/render/shader_nodes/textures/ies.html

  • $\begingroup$ Thanks a lot! Only 300k lamp profiles to go through! ;) I guess the only things I just discovered is that it doesn't require a spot specifically, and that the radius needs to be 0 or close to it. But yeah, the IES is exactly it. Much appreciated! $\endgroup$ Jul 30, 2021 at 21:12
