light dripping, blasting, leaking

[SHCanada2]

or any other adjective of your choice. anyone know how to fix the fluorescent light in the ceiling from doing this, I've been watching the CA video, but I do not see that they have this issue

thanks

 

 

 

pot lights dont seem to have the same issue:

How's it look with the lights dimmed way down?

Can be tricky. Open the light, go to light data tab. Click show position in camera, sometimes changing the offset fixes, sometimes changing to spot which has other issues and sometimes changing lumens as Gene suggest....sometimes a combination. Once satisfied uncheck show postion.

Just from looking at the images I can think of a few issues I'd check:

• Light source is too intense, decrease the lumens
• Try adjusting the absolute elevation of the light source
• You're getting too much reflection from the ceiling, is is set to matte or general material?

You can also try turning the "daytime backdrop intensity" to something around 500

they were down  to 100 lumens. only at zero does it go away

I tried this by changing the distance relative to ceiling, then it became worse

I have this, should it be something different?

tried moving to center, changing from spot to point. no difference:

 

 

as part of the core catalog, one would think the settings should be correct, and so perhaps something else, or maybe not...

Use the 'Adjust Material Definition' tool (Rainbow tool) to adjust the material properties for the ceiling.

Moving it works for me.

Yeah that would be nice. The content team does a really nice job overall. RTRT is relatively new and there are thousands of symbols with many needing adjustment, first when PBR came out and then again with RTRT. Did you send in a report/request? Might want to do that. In the meantime once you have one working add to user library, then replace all from library and in the future you can just grab it.

that was going to be my next question if I do not get it working...does someone have one that does. I'll adjust the ceiling definition and see if I can mimick your results in the meantime. what are your settings for light 1 and light 3? You screenshot shows that your light 2 is camera only . does that mean it is being used for RTRT, or not being used?

 

The documentation seems non descriptive (does "regular 3D view" include RTRT?)

• Select Use in Camera View to turn the selected light source on in regular 3D views only.
• Select Use in CPU Ray Tracing to turn the selected light source on in CPU Ray Trace views only.
• Select Use in Both to turn the selected light source on in both camera and CPU Ray Trace views.

changing the ceiling to a texture and keeping the light source with no offset, seems to have worked:

 

Thanks all.

 

something else funky happened, I changed the ceiling texture back to the stock color-bone, which has no texture and now the ceiling is no longer shiny and the bleeding is gone

 

...go figure

Image is 4 walls with roof and foundation using OOB defaults (including ceiling), 3 lights are from core library. The only change made to any is what is shown in image-light 2. Lights 1 and 3 of the fixture are already at -6. and 0. As Eric pointed out sometimes it's a glossy material that needs adjustment as well or instead.

Sometimes with a render open after it refreshes things are not quite the same (sometimes not so good) Could be that or could be possible the ceiling was painted accidentally? It happens when using spray can on something set with same material which one (of several) reason to use defaults to change materials.
