These include: Bump mapping Bump mapping is a texture mapping technique that simulates small-scale bumps, wrinkles, ridges, and other surface irregularities by altering the surface normals of a mesh but without actually changing the geometry.

World position offset simulation for ray traced instanced static meshes (beta) Allows ambient motion of foliage like trees and grass. Uses approximate technique of shared animations to reduce overhead for simulating a full forest. Inexact Shadows (beta) Deals with potential mesh mismatches of ray traced and raster geometry.

However, using a configurator in a built environment presents multiple challenges including 3D meshes changing shape, shadows not lining up, and materials reflecting different lighting and colors. Because the lighting is baked in, it’s difficult to test out multiple lighting scenarios. Photo courtesy of Theia Interactive.

Notably, Windows users could experience crashes when baking lightmaps. Import: glTF: Improved error handling around invalid images and invalid meshes ( GH-48904 , GH-48912 ). Physics: Fix ragdoll simulation when parent was readded to scene ( GH-48823 ). was thus subject to this crash when baking lightmaps.

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?

It uses ray tracing to provide infinite bounce in indirect lighting, without the need to bake lighting or create multiple light setups for scenes.

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.
