Problem render vray revit

[Anonymous]

Good evening everyone, I just started The rendering came out dark even in the project artificial lights and the sky, even if the light is the rendering without solar output something that has not happened doing a normal render on revir.
By chance can you tell me how to set up the render to show the external and internal lights?
Many thanks to all.

You need to go into the Vray Asset Browser (located in the Vray tab of Revit), and search for your modeled lights/lamps in the filter search bar up the top. Usually you can find them by searching lamp/light etc, but if not; select one of the lights in Revit, edit type, and check the material name under "materials and finishes" - this is what you should search in the Asset Browser.

Once located in the asset browser, use the drop down tab on the right of the material to change it from "Autogen" to "VrayMaterial". This will open your file browser to Vrays material options. Select a new material for your lights. Go to the emissive folder and select a light of your choosing, e.g LED_8000k. 

Now the lights will show in your renders, to change their brightness you can do this in the "edit type" tab for your lamps/lights in revit - just scroll to "photometrics" and change the initial intensity value accordingly.
