HTrace SSGI doesn’t require any kind of baking or asset pre-processing and is designed to work out of the box with little to no tweaking.
MAIN FEATURES:
• Full Integration into the Rendering Pipeline: automatic resource injection with no need for manual setup or package customization. HTrace SSGI overrides native indirect lighting resources, ensuring compatibility with other rendering effects.
• All Rendering Paths: fully supports Deferred / Deferred+ / Forward / Forward+ rendering paths, with no visual or quality differences between them.
• All Light Sources: compatible with all light types, including emissive materials that function as actual light sources and cast indirect soft shadows. Performance remains unaffected by the number of lights in the scene.
• Dynamic Environments: designed for fully dynamic and procedural environments where objects, materials, and lighting can change in real time with no extra performance cost or preprocessing.
• APV Fallback & Enhancement: natively supports Adaptive Probe Volumes as a fallback option. Enhances APV output by reducing light leaks and noise from low-resolution bakes, while adding fine GI details and occlusion from both static and dynamic objects.
• Advanced Denoising: powered by a cutting-edge ReSTIR Validation algorithm that maximizes temporal responsiveness, while preserving small details and keeping indirect shadows sharp during spatial filtering.
• Scalability: provides an adjustable Render Scale parameter for downscaled rendering, along with a wide range of options to fine-tune the effect and balance speed with quality.
• Infinite light bounces: simulated through a feedback loop, with each frame capturing an additional bounce of light.
• Render Layer Mask: selectively exclude objects from casting and/or receiving indirect lighting on a per-layer basis via the Render Layer Mask.
• VR Support: single-pass VR is supported.
• Open Code: the code is open for modification. If you have questions about how it works, feel free to reach out to us on Discord.
