Modeling of realistic recessed lighting with free light problem.

[suldikmann]

Hello! Anyone can help me? I want to create a realistic recessed lightning but when I put the free light inside of stainless metal casing/housing there is no reflection of the light.

It may be that your light is a point light, in which case there isn't much surface area to reflect. If you make a bulb and give it a self-illuminating material, it'll show up in the reflections. You'd need to make sure your photometric light source is either below the bulb, or excludes the bulb from shadow casting. I'm not familiar with Vray, but to reduce render times you might also want to have your self-illuminating material not cast light into the scene, but only be visible to reflections (which is an option in mental ray). Of course, you could also give your photometric light source some area (make it a sphere instead of a point) instead of making a self-illuminated bulb object, but that may also drive up render times.

Are you putting a ies light in the set up, which in itself won't give a light either in the spot, as it generally sets slightly down from the lamp.

A sphere with vray self illuminating material on it would do it or put it in after in Photoshop.

 

Your doing nothing wrong, it's a learning process.

Thanks a lot guys! Your suggestion opens me to tweak and try more.

You can override the IES shape + adding lens effects to produce the effect you wish for.
