Leungchunghong Posted August 29, 2021 Share Posted August 29, 2021 I have this light reflected from outside's rope light... The wall should not let any light from outside shine through. Even with render, similar issue. How can i fix it? Link to comment Share on other sites More sharing options...
Solution Chopsaw Posted August 29, 2021 Solution Share Posted August 29, 2021 Try placing a polyline solid through the wall connection and apply a lead material to it about 1" thick. If that does not fix it you might want to upload your file here or send it to tech support. Link to comment Share on other sites More sharing options...
rgardner Posted August 29, 2021 Share Posted August 29, 2021 Just to make sure the obvious is done make sure there is a roof on it. Link to comment Share on other sites More sharing options...

I tried adding Polyline solid to whole wall. 10mm, still goes through until 50mm., but the wall overall thickness increased significantly. So I changed the material to "Grey Shade", yes it blocked the light. I believe the material does matter. Thanks Both. Link to comment Share on other sites More sharing options...

I just know that lots of times when it is a light bleed it is something that is not placed properly and is reflecting the sun from the outside as its penetrating the roof, there is no roof, or the roof is not placed properly and joined together. I would just say toggle off the sun and see if it persists so you can rule out one of those issues. Link to comment Share on other sites More sharing options...
