Add transparency support for LightmapGI Currently when baking lightmaps users have to choose between transparent objects casting shadows as if they were fully opaque, or not casting shadows at all. This has been a major limitation in both the quality of lightmap baking and the ergonomics of the lightmap baking workflow.

New tools New debugging tools like the BVH viewer and Ray Timing Visualization allows developers to get a handle on ray tracing cost in their scene and get it tuned for speed. World position offset simulation for ray traced instanced static meshes (beta) Allows ambient motion of foliage like trees and grass.

Notably, Windows users could experience crashes when baking lightmaps. Physics: Fix ragdoll simulation when parent was readded to scene ( GH-48823 ). Physics: Fix crash on debug shapes update if CollisionObject is not in tree ( GH-48974 ). was thus subject to this crash when baking lightmaps. API documentation updates.

Ensure your meshes are marked as "Static Bake", then enable SDFGI in the Environment settings. Multiple Bounces: Enable a feedback loop, which simulates multiple bounce lighting. SDFGI is mostly leak free, unlike VCT techniques which are the most common in use today (like SVOGI/GIProbe/etc). How do you use it?

Q: Does the scene have to be pre-baked in any way to use ray tracing and/or path tracing? Pierre: The path tracer does not require any pre-baking, thanks to its more brute force (and slower) approach to lighting.

UE4 plugin (Download here ) Leveraging the power of ray tracing, RTXGI provides scalable solutions to compute multi-bounce indirect lighting without bake times, light leaks, or expensive per-frame costs. RTXGI 1.1.40 As a developer, System Latency (click-to-display) can be one of the hardest metrics to optimize for. and natively supported.

RTX Global Illumination (RTXGI) Leveraging the power of ray tracing, the RTX Global Illumination (RTXGI) SDK provides scalable solutions to compute multi-bounce indirect lighting without bake times, light leaks, or expensive per-frame costs. Version 1.1.30 allows developers to enable, disable, and rotate individual DDGI volumes.
