Need help with Enscape lightning

Im new to Sketchup + Enscape, In the 1st image, circled in blue are lights onto the roof from the moving head lights on the stage, I have already got the moving head lights, and put the emissive texture onto the part, giving a glowing effect, but the light is not going on the roof, how can I fix it to make it go onto the roof?

Could you explain yourself a bit better?

Start with the basics in SketchUp first, then in Enscape. After that move on to more advanced things.
In V-Ray for SketchUp, I used a texture in a Spot Light and enabled Volumetric Environment. This way I was able to project those lights onto a surface, and the rays from the light reflector also appear visible. See if you can find the equivalent of these options in Enscape.
