Strange Light Artifacts During Render

Recommended Posts

Hey everyone -


Just getting started with C4D and have been working on my first render - but have reached a roadblock. My file consists of a floor, infinite light (to act as the sun), physical sky, background, camera, and airplane object. I'm trying to render a nice, high resolution pic for some photoshop, post-work, however, these strange light artifacts are appearing on the bottom edge and around the canopy. When I turn off the infinite light, the strange lights disappear, but I can't seem to determine where these are coming from. Please let me know if other menu screenshots are needed to sleuth this one out. Thanks so much!!

Try removing the specular component for the materials applied to the parts where your artefacts appear...

Also (unrelated to your issue) just checking you have disabled the sun in the Physical sky, otherwise you'd have 2 suns in the scene...
