How can I add fake lightning in Revit?

Jorgensen · Mar 4th 2020

Hi

If i want to light a building, without using "real" light sources, but just place a large rectangle object as a light, and then make it invisible to the camera - is that possible?

Anyone?

Hello Jorgensen,

I am not sure if it is what are you looking for. However.

The flat plane is just to bring the light into position, then I set the "visible" parameter to unvisible.

Best regards, Hans

Hi @Hans Schmid

Thanks for your input.

I've tried your suggestion. I modelled in-place a lighthtning device (just a simple box) - added a material with some self illumination, then I unchecked the "visible" option under graphics, but then both the object and the light diassapers :-/

What do I do wrong?

Trust me I have done something like this - use a plane + emissive texture. It tends to create a lot of noise in the render.

It is best to use lighting family with Revit light source --> array --> group the light in your scene for better contorl.

Jorgensen , I also advice against using such a large emissive surface, especially when it's the only light source - this will just create noise which can be avoided by using the built in lights of Revit instead, maybe multiple at once as mentioned by joeykeys .

Also, I'm not entirely sure either how Hans Schmid made it invisible without removing the emitted light. I'll try again, but he'll get back to us again anyway probably.
