Whenever I produce interior renderings, I always encounter the problem of white light splotches on wall and/or other surfaces. I have searched the internet for solutions to this problem but have been unsuccessful in finding the primary cause in this error. The goal is to simply have a clean well lit and shadowed interior room rendering.
Additionally, when I ran a 'Draft' rendering of the same image, it gave no indication that there would be white splotches as shown in the higher quality rendering. Why does the lower quality Draft rendering show no splotches, while the higher quality one does?
Although I have turned on "Daylight Portals- Windows" in the rendering settings, it does not register as the render processes; the Rendering Progress Bar shows:
Artifical Lights: 4
Daylight Portals: 0 <----?
Notice that even though it does not register the window Daylight Portal, light still passes through the glass on to the floor.
Both the draft rendering, higher quality rendering, and progress bar image are included in the attachments.
Any further recommendations to make this scene more successful would be highly appreciated.
