A high performance global illumination pathtracing renderer built in unity for others to use with full support for rendering complex scenes without RT coresRequires Unity 2021+Full URP support is still experimental due to the wacky postprocessing URP has that likes to randomly flip the screen verticallyNote: while it is capable of it, this isnt really for realtime, instead its more for rendersBuilt from the ground up for others to use, this is a renderer that uses pathtracing to create realistic images. I have tried to design this to be customizable and easy to use.This is still heavily WIP, thus I highly encourage you to tell me about any ideas, issues, possible improvements, and things you wish were supported/changed.Also highly reccomend you check out my small discord for links to everything and how to contact me(about anything): https://discord.gg/4Yh7AZuhcDPlease consider becomming a supporter on patreon, as while my goal is to make this easily available to everyone and free, it takes a lot of time and effort to continue to work on this that I could be spending on something else(link in discord)Demo: https://drive.google.com/file/d/14v4RdvXi7jA6rLJgQOBo2lRWjBKkFYCj/viewMost images were rendered by YanusForum: https://forum.unity.com/threads/truetrace-released.1398313/Features: High Performance Compute Shader based path tracing without RT cores Compressed Wide Bounding Volume Hierarchy for High Performance Software RT No specific GPU vendor needed Hardware RT Support for modern cards Full Disney BSDF for materials Full support for complex emissive meshes Runtime transform, add, and removal of objects Runtime modifiable materials ASVGF for realtime denoising OIDN for offline denoising PBR Texture Support Next Event Estimation with Multiple Importance Sampling Efficient Light BVH from PBRT 4 for Next Event Estimation Support for all default unity lights(Using Next Event Estimation) Bloom, Depth of Field, AutoExposure, TAA, FXAA, Tonemapping Precomputed Multiple Atmospheric Scattering for the sky Object Instancing(Without RT Cores) ReSTIR GI(cursed implementation) Simple upscaling ability Supports Built-in, HDRP, and URP(WIP for URP) Full skinned mesh support Supports deformable standard meshes Supports unity heightmap terrain and heightmap trees Environment Map Importance Sampling Radiance Cache Material Preset System Efficient Panorama Rendering IES for spotlights True Bindless texturing(Thanks to Meetem)
