A high performance global illumination pathtracing renderer built in unity for others to use with full support for rendering complex scenesRequires Unity 2021+Built 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 tracingCompressed Wide Bounding Volume Hierarchy for High Performance Software RT(When RT Cores are disabled)Hardware RT Support for modern cardsFull Disney BSDF for materialsFull support for complex emissive meshesRuntime transform, add, and removal of objectsRuntime modifiable materialsASVGF for realtime denoisingOIDN for offline denoisingPBR Texture SupportNext Event Estimation with Multiple Importance SamplingSpherical Gaussian Light Tree or PBRT Light BVH for Next Event EstimationSupport for all default unity lights(Using Next Event Estimation)Bloom, Depth of Field, AutoExposure, TAA, TonemappingPrecomputed Multiple Atmospheric Scattering for the skyObject InstancingReSTIR GISimple upscaling abilitySupports Built-in, HDRP, and URPFull skinned mesh supportSupports deformable standard meshesSupports unity heightmap terrain and heightmap treesEnironment Map Importance SamplingRadiance Cache for Fast Indirect LightingMaterial Preset SystemEfficient Panorama RenderingIES for spotlightsTrue Bindless texturing(Thanks to Meetem)Convolution Bloom(Not mine)Vulkan and Metal support(Your mileage may vary)Mesh slicing using SDFs(Does not modify meshes, for rendering cuts only, like cross-sections)Lambert or EON(default) diffuse modelsFull Multiscatter Fog(Not realtime)Orthographic Camera SupportPhoton Mapping for fast(but not realtime) causticsAnimatable Material Properties
