ISSUE DESCRIPTION
The simulator displays two critical graphical artifacts affecting the aircraft’s external lighting:
-
Spherical Occlusion/Flare Artifact (“Black Hole”): A solid, black, spherical artifact — resembling a “black hole” or dark smudge — intermittently appears in the camera’s view. This occurs when the aircraft’s landing or taxi light is active and directed toward the camera or a nearby surface (such as the runway). It appears to be a rendering bug related to the light flare, volumetric light effect, or its occlusion handling.
It’s indeed affected by the known AMD RX 9000 series issue (see this), but the effect shouldn’t be this exaggerated. In the first place, there shouldn’t be a completely black sphere appearing at all. Other aircraft don’t show this behavior, or anything close to it — it seems overly pronounced only on the Cirrus.
-
Abnormal/Exaggerated Navigation Lights: The navigation and strobe lights produce an excessively intense, solid-colored halo that creates unrealistic colored streaks (purple, green) across the aircraft’s wings, instead of a soft, diffuse glow.
-
Incorrect Navigation Light Colors and Reflections: The navigation light colors and their reflections on the runway appear inverted and inconsistent. The right wing emits a red light, but the runway reflects green. The left wing emits a greenish-blue light instead of pure green, while the runway reflects red. This suggests a rendering or shader issue affecting color assignment and reflection mapping.
FREQUENCY OF ISSUE
Occurs consistently whenever the aircraft is loaded and external lights are active. Reproducible under all time and weather conditions (day, night, clear, rain, etc.).
REPRODUCTION STEPS
-
Load a flight using the Cirrus SR22T aircraft.
-
Set any time of day or weather condition.
-
Turn on all external lights (Landing/Taxi, Strobe/Beacon, and Nav Lights).
-
Use the External, Drone, or Character Mode Camera and position it so the landing/taxi light faces the camera or reflects off a surface (runway or fuselage).
-
Observe the black spherical artifact and exaggerated color halos.
YOUR SETTINGS
- I’m not using Developer Mode.
- My GPU is an ASUS Prime AMD Radeon 9070 XT OC 16GB, and my CPU is an AMD Ryzen 7 9800X3D.
- No add-ons are installed in the simulator. The bug occurs both in the SU4 beta and the stable version.
