kwhitt Posted January 31, 2020 Share Posted January 31, 2020 I started using X12 yesterday with an X11 file. There is a light source in my layout that I cannot find - images attached. When I go to 3D > Lighting > Adjust Lights to find the culprit, there's nothing there. Anyone have any ideas where this light might be coming from and why it doesn't show up in the light list? It's not the sun for sure... Thanks, Kevin Link to comment Share on other sites More sharing options...
TheKitchenAbode Posted January 31, 2020 Share Posted January 31, 2020 You are most likely seeing the hidden automatic light that CA puts in if you have no lights in your plan. Just place any light in the plan, it does not have to be turned on and CA will not put it's own light in. Just be aware that with no lights your scene may be very dark. 1 Link to comment Share on other sites More sharing options...
Ridge_Runner Posted January 31, 2020 Share Posted January 31, 2020 Guessing...do you have any symbols not displaying that might be set as a light source? 1 Link to comment Share on other sites More sharing options...
kwhitt Posted January 31, 2020 Author Share Posted January 31, 2020 Graham - thanks for the reply. I will attempt to place my own light to override the default. Mike - funny thing - when I switch over to PBR, the casing around the door glows like a light source. That said, I believe that is an entirely different issue that I've heard mentioned before...

kwhitt Posted January 31, 2020 Author Share Posted January 31, 2020 Yes, placing my own light turns off the default placed by CA. Thanks for the help! Link to comment Share on other sites More sharing options...

If you have glowing surfaces that may be due to the surface material having an emissive setting. Best way to find these is to turn off all lights, set your sun intensity to 0 and toggle the sun off. Everything in the scene will be black except materials with an emissive setting. Emissive is useful but you need to be careful as overdoing it can really screw up the scenes lighting. The only other time an object may glow is if it penetrates say a wall so part of it is on one side and other part is on the other side. If one side is brightly lit CA may use that light to generate the materials appearance versus the light within the room that the camera is in. 1 Link to comment Share on other sites More sharing options...

I've had this occur when a wall, or section of a wall is defined as no room definition. Attached were in X11 No room definition Change to room definition I chased lights, added subtracted and adjusted when this happened. The only thing that worked was changing the room definition. Yes it was sent in. 1 Link to comment Share on other sites More sharing options...
