Hi Paul

Are lighting portals possible in Revit plugin?

cheers

Yes, simply change the material type to "portal". IMO, using the "fake_shadows" on a "specular" material is better suited to Revit, since Revit will already have the cavity (from the window geometry).

hi Paul

Could you please clarify what you mean by IMO

Also, do I create a material called portal? as it doesn't exist in the materials?

thanks and sorry for the lame questions

IMO = "In my opinion"

There is a portal tutorial in the resources forum here.

For Revit, if you were going to use a portal, I /think/ you would have a plain with a glass window, then set the material type of the glass in that window to "portal". But I think (and there are people here with far more expertise in this area than me), you are better off leaving the glass material as specular with "fake_shadows" on, and reduce the opacity (or increase the kernel indirect light importance) if the lighting coming through the glass is causing too much graininess.

I'm not certain, but I suspect the "fake_shadows" pin in the specular material makes the portal material less commonly used - but hopefully people with more knowledge than I on this may comment.

Thanks Paul

Been meaning to ask if the plugin is a "full octane render or has it been stripped and minimised for application like Revit"

just a general knowledge for me.

cheers

It's the full renderer. Same speed, capacity, nodes, etc. I think the gradient node is about the only thing that's in Standalone but not in the plugins.

thanks
