Classic Sponza - Unreal Engine Remaster

Summary

The Atrium Sponza Palace scene is widely used by graphics programmers and artists. It provides an ideal lighting test environment as it contains both indoor and outdoor areas.

The goal of this conversion was to modernize the project in key areas and make it compliant with modern rendering standards.

Please refer to the Releases page for Unreal Engine compatibility.

The Unity version of this project can be found here.

Features

• Physically accurate lighting and exposure.
• Manually created Lightmap UVs.
• Baked Global Illumination using GPU Lightmass.

Troubleshooting

LIGHTING NEEDS TO BE REBUILT message in the viewport

1. In the top menu bar, navigate to Build > GPU Lightmass.
2. In the window that opens, uncheck the Viewport Realtime is ON checkmark. This will speed up the baking process.
3. Click on the green Build Lighting button. You can also build the lighting using the old CPU Lightmass, though keep in mind that the results will not be the same.

REFLECTION CAPTURES NEED TO BE REBUILT message in the viewport

1. In the top menu bar, navigate to Build > Build Reflection Captures.
2. Wait for the process to complete.
