Hi there I am working on using photmetric lighting combined with the daylight system within my kitchen scene, all was going well till these white circles kept appearing in my scene ! Now i can't seem to get rid of them.
The picture attached shows the render even when all lights deleated, including the daylight system !!!! the spots are still there and there is light ourside in my enviroment.
I think its due to the exposure control ??
Any help would be greatly appriciated and tips on using these two lighting sources togeather
Many thanks for your time
I've seen something similar in the past and it was due to the window material (glass). For testing purposes try hiding the window panes or just hide the window completely.
If that does the trick then I suggest trying replacing the material on the window pane to an Autodesk Glass or an Arch & Design "Glass (Thin geometry)" material.
Also are you using any mr Sky Portals?
If what Ben suggested doesn't work, try this with exposure control
Go to pulldown menu RENDERING > Exposure Control
Change the exposure to Physically Based Lighting, Indoor Daylight which will set your exposure control to 10
Hi, those white circles are the photons emitted in your scene.
This is a problem in your render settings, global illumination tab and your lights.
- First, your photons are little bit small, take a look at your photons emitting lights and check "Automatically Calculate Energy and Photons".
Smaller Photons = need more photons to cover your scenes.
- Make sure your scene use real world measurement.
- Enable Final Gathering
- Photon Mapping (GI) is probably already checked, use default settings for your tests.
- In light properties (Global illumination tab), default number of photons is 20000, just try 40000 and 60000.
Now you can add a Mr Photographic Exposure Control to adjust the exposure.
