Mass families can be created as a single plane and nested into a light fixture to provide a planar emmiter

Do you see the extrude entity in your render?

This is a similar situation that we are encountering in the Inventor plugin - how do you add point lights etc into an architectural scene as geometry, but keep them out of the bill of materials. And as indicated before, the light really needs to come from "lights" (models in the scene) otherwise the lighting will not be realistic. But there is often a need for fill lights and other lighting to speed up the render process, and in this case the geometry needs to be added to the scene - but it cannot appear on plans or the bill of materials. So there are many options (and Revit guru will be able to thing up many more than I can offer), but adding a single plane (modelled in something like Rhino) and used as a proxy to a Studio Light element will work well. If you want to do it all in Revit - follow MB's advice. Or you could make your own family object for a Studio Light (which has geometry) and load it in to the scene (I haven't got into the Revit Bill of Materials - but I'm sure there is one, and you'll need to exclude that element from the list). Or model it in place (similar to the process for decals - http://render.otoy.com/manuals/Revit/?page_id=497).

Hi Paul
I came across a Octane Tutorial on youtube by MTIMTAM
http://www.youtube.com/watch?v=Tedj2lEKvuE

(thank you MTIMTAM)

Here he is discussing a way to have either single face extrude as lights or mesh but they can be made invisible yet keeping the light emission


Wonder if you would be able to take a look at it (around the 12 minute mark on the video)

This would really help us Revit guys if you could some how see how that translates to your plugin.

Thanks in Advance


cheers

Just use my material from the screenshot earlier in this post and set the opacity to 0. If that's what you were trying to achieve all along, I apologize for misunderstanding your question.

Spot the light ....

Simple room with no openings or lights ...

As suggested before - created a plane mesh in Blender to shine downwards (flipped). Then replaced the Revit studio light with the exported OBJ from Blender (Proxy). Set the material to Diffuse and emission as blackbody. Set the Opacity to 0. ps I'll post the files if it helps? ... You'll need to reload the Proxy file to suit your directory location. Select the Studio Light in Revit and with the Material selected change the Opacity back to 1 to see the mesh plane ...

Many thanks
