Rendering & lighting

Overview

• Vulkan is the main backend. DirectX 12 is available on Windows as an experimental backend.
• Clustered deferred shading supports large numbers of dynamic lights. Translucent materials use a forward clustered pass.
• Baked lighting comes from the lightmapper built into the editor, along with reflection and irradiance probes for moving objects.
• Realtime GI & reflections: In addition to our baked lighting, we do support realtime GI for HWRT-supported devices. (DDGI and ray traced reflections). For non-HWRT we have screen space reflections. Screen space global illumination deprecatation is planned so it is not recommended to use
• Shaders are written in HLSL, compiled with DXC, and reload live in the editor on save
