******************************** * VOLUMETRIC LIGHTS * * Created by Kronnect * * README FILE * ******************************** Requirements & Setup -------------------- 1) Volumetric Lights works only with Universal Rendering Pipeline 2) Make sure you have Universal RP package imported in the project before using Volumetric Lights. 3) Make sure you have a Universal Rendering Pipeline asset assigned to Project Settings / Graphics. There's a URP sample asset in Demo/URP Pipeline Settings folder. Demo Scene ---------- There's a demo scene which lets you quickly check if Volumetric Lights is working correctly in your project. Documentation ------------- Please read the documentation folder for additional instructions and options. Support ------- * Support-Web: https://kronnect.com/support * Support-Discord: https://discord.gg/EH2GMaM * Email: contact@kronnect.com * Twitter: @Kronnect Future updates -------------- All our assets follow an incremental development process by which a few beta releases are published on our support forum (kronnect.com). We encourage you to signup and engage our forum. The forum is the primary support and feature discussions medium. Of course, all updates of Volumetric Lights will be eventually available on the Asset Store. Version history --------------- v10.4.2 - [Fix] DX12 + Forward+/Deferred+ fixes. Translucency feature not supported in this specific setup. It will fallback to regular shadow casting with no translucency. v10.4 - Improved support for custom shaders used in translucency: added custom texture name and color options to Volumetric Light Translucency component v10.3.1 - [Fix] Fixed Unity 6.1 shader struct GBufferData naming conflict v10.3 - Added "Ignore Overlay Camera" option to all render features v10.2 - Added "Ignore Rotation Change" option to baked shadows. This option allows baked shadows to rotate with the light, improving performance. - Improved performance while in edit mode v10.1.1 - Added DOTs instancing support to depth prepass shaders - Added helpful links and tips to the inspector v10.0.2 - Performance optimizations for disabled lights v10.0 - Added support for Render Graph (Unity 2023.3) v7.1.1 - [Fix] Fixed VR issue using OpenXR v7.1 - Small improvements to light diffusion effect v7.0 - Added "Shadow Color" option. Shadow color can now be customized (also alpha) to create many special effects with Blend Mode. v6.9 - Added Near Clip Distance to spotlights v6.8.2 - [Fix] Fixed material issue when a light is duplicated in Unity Editor - Added "Dust Prewarm" option. By default, dust particles are prewarmed/populated during activation. This behaviour can be disabled to gain performance when activating many lights at the same time. v6.7 - Improved rendering of large area lights v6.6.1 - Optimized mesh data reuse / generation based on settings change v6.6 - Added "Local Space" option to "Use Custom Bounds" - Improved generation of volumetric light area on directional lights v6.5.2 - Option to ignore reflection probes in the depth pre-pass render feature - The volumetric lights render feature now excludes reflection probes based on its culling mask - [Fix] Fixed issue with translucency rendering in newly created lights that required additional initialization v6.4 - Translucency script: option to preserve original transparent shader - Translucency effect uses also Lit shader base color - Added cookie offset parameter v6.3 - Added "Blend Mode" option to Cast Direct Light feature v6.2 - Added "Substractive" blend mode - Translucent shadow map: supports transparent texture scale/offset properties - Changed dust particles wind speed behaviour so a value of zero stops particles completely (as expected) v6.1 - Improved blur quality - Added button to post process inspector to quickly return to latest selected volumetric light - Fixes v6.0 - Added support for translucent shadow maps - New demo scene: Church - Added "Cast Direct Light" option (requires deferred rendering path) - Added Unity 2022 compatibility - Light shadow optimizations in Unity 2021.3 and above by using dedicated depth renderer - Added cookie scale & speed options v5.1.2 - Performance improvements related to particles when not in playmode v5.1.1 - [Fix] Fixed depth test issue on WebGL - [Fix] Fixed effect disappearing issue when saving the scene v5.1 - Added "Raymarch Max Steps" setting which can be used to top the number of samples and improve performance - Shader optimizations v5.0.3 - Minimum required Unity version is now 2020.3.16 - [Fix] Fixed particles intensity not reflecting light intensity changes v5.0.2 - Updated documentation with built optimization tips v5.0.1 - [Fix] Fixed material keywords being reseted when saving scene in Unity 2021.3 v5.0 - Added Bake Mode option for point light shadows. Choose between Half Sphere, Cubemap (1 face per frame) or Cubemap (6 faces per frame) - [Fix] Fixed lengthy compilation time in Unity 2021.2 v4.7 - Added new demo scene (temple) v4.6.2 - Added Xbox compatibility v4.6.1 - Added dithering option to Volumetric Lights Render Feature - Volumetric Lights Render Feature optimizations - Shadow occlusion render texture optimization v4.6 - Added downscaling option to Volumetric Lights Renderer feature v4.5.1 - Improved edge preservation when blur option is used v4.5 - Added custom depth prepass for improved support of transparent and semi-transparent objects v4.4.1 - Target camera property is now exposed for all light types (used for autoToggle options) - [Fix] Fixed mesh being generated by inspector when volumetric light is disabled - [Fix] Fixed PS4 compilation issue v4.4 - New option Shadow Orientation for point lights - Optimization related to baked shadows for point lights in OnStart mode v4.2 - Added auto-toggle "Time Check Interval" parameter. - Removed macro console warning in Unity 2020.1 - When "Sync With Profile" is enabled, properties in inspector are now readonly - Using cookie texture no longer requires occlusion cam improving performance v4.1 - Simplification. It's no longer required to create a volumetric light profile to use the effect. - Timeline support is now simpler. The VolumetricLightAnimation is no longer used. Instead you can modify directly the VolumetricLight fields. v4.0 - Added global blur option (check documentation) - Removed top limit for shadow intensity - Prefab instances no longer forces unpack - [Fix] Fixed an issue when creating a volumetric point light in prefab mode v3.6.5 - Improved compatibility with Unity 2020.3 - Removed a harmeless Editor warning message related to 3D textures v3.6.4 - Profile must now created specifically when using volumetric lights in prefabs v3.6.3 - Improved dust particle rendering v3.6 - Shadow pass optimization when dust particles are also enabled - Added support for Timeline/Animation (check documentation to enable this option) - [Fix] Fixed an issue with occlusion camera being destroyed during a physic event resulting in a console error - [Fix] Fixed/changed the way spotlights render when angle is >90 v3.5 - Added support for "Colored Cookie Texture" (new option in profile) v3.4 - Added ability to dim and/or deactivate volumetric effect based on distance.
