Reflectivity, Ray Tracing and Shadows Glitching on Complex Mesh/Terrain Geometry

D5 Render Version: 2.4
Graphics Card: RTX 3090
Driver Version: NVIDIA 531.29

Issue Description: Reflectivity, Ray Tracing and Shadows Glitching on Complex Mesh/Terrain Geometry.

Screenshots/Videos Description:

Steps to Reproduce (optional): Export from Archicad Using D5 Exporter - most if not all complex geometry beyond a certain amount of polygons (curves are a big culprit) - do not render properly and display as “Dark” or “fully shadowed”. When moving around the viewport, the road appears “Glossy” even when specular values are low.

Similarly, water puddles cannot display properly on this surface as something potentially related to the issue.

In the image of the road here, you can see the car generates no shadows (there should be long shadows here) and generally we cannot improve the rendering quality beyond a flat, unrealistic looking surface.

Please let me know if there are any methods around this or fixes.

Thanks,
Peter

Hi, this may be caused by turning on smooth mode. You can check the smooth mode switch, please refer to the picture:
