Hi, i have an island and there is a cave inside. even without any lights inside the cave, a strange fog appears. The other thing is that my character receives a lot of light when walking through the cave. Does anyone have some tips where this behaviour could come from?
UE4 like other 3d Software simulates ambient lighting, lighting that comes from bounce light in an environment. I usually keep my World Settings tab open, and doc it along side my Details, along with Levels to find important information like the lighting.
In there is a setting called Environment Color : try setting that to black to see what happens.
Then work on eliminating your lighting to debug, and see if anything else is contributing.
Set your DirectionalLight to Intensity : 0.0
Look for other lights that may have a huge attenuation. Eliminate them by setting the intensity to 0.0 to see what is causing the problem.
Duplicate directional lights would not be a good thing in my experience playing havoc with shadow maps, fps and render times.
Hi Finn thank you for your great tips, they made me more aware how to use my lights. In the end i had a to highvalue in the Cascaded shadow maps>DynamicShadowDistanceStadionaryLight. The ExponentialHeightFog had a to low start distance value what gave my the strange white fog. jiepie everything good now. Thx.
