【更新】Umbra Soft Shadows - Better Directional & Contact Shadows 6.0
Unity 6 compatible
Nominated for Best Artistic Tool in the 16th Unity Awards.
Umbra significantly improves the quality of directional light shadows in the Universal Render Pipeline (URP) for Unity. It introduces advanced shadow rendering techniques, resulting in beautiful shadows that are sharper near obstacles and softer, more diffuse, at a distance, thanks to its implementation of contact hardening.
Umbra also adds Contact Shadows to enhance fine details at close and far distances. Combining the powerful soft and contact shadows you will get the most realistic and immersive scenes.
Key features
Configurable Shadow Appearance: Adjust the look and smoothness of shadows to achieve the desired visual style for your project.
Contact Hardening: customize the shadows to look crisp near the shadow casters while smoother at the distance as in real life.
Stylized Shadows: now you can texture the shadows or create a posterization effect when using blur (great for toon style).
Contact Shadows: get shadows for all small details without compromise, either at close or at far distances. Combine it into the resolved shadow texture or render it as a separate pass.
Cascade Blending: Achieve smoother transitions between shadow cascades, reducing noticeable edges and enhancing overall visual coherence.
Profiles: Easily store settings in profile assets which can be easily swapped or set at runtime.
Optimization Options: Advanced options to improve performance such as loop and frame skip optimization which allows reusing of shadow map texture from previous frame.
Transparent Receiver Plane for XR: Includes a custom shader made with Shader Graph that supports soft shadows rendering on a transparent plane/ground commonly used in XR applications. Demo scene included.
兼容 Unity 6
获得第 16 届 Unity 奖最佳艺术工具提名。
Umbra 大幅提高了 Unity 通用渲染管道（URP）中定向光阴影的质量。Umbra 引入了先进的阴影渲染技术，通过实施接触硬化技术，使靠近障碍物的阴影更清晰，而远处的阴影则更柔和、更漫射。
Umbra 还添加了接触式阴影，以增强远近距离的精细度。结合强大的柔和阴影和接触阴影，您将获得最逼真、最身临其境的场景。
主要功能
可配置的阴影外观： 调整阴影的外观和平滑度，以实现项目所需的视觉风格。
接触硬化：自定义阴影，使阴影投射者附近看起来更清晰，而远处则更平滑，如同现实生活中一样。
风格化阴影：现在您可以对阴影进行纹理处理，或在使用模糊时创建海报效果（非常适合卡通风格）。
接触式阴影：无论是近距离还是远距离，都能毫不费力地获得所有小细节的阴影效果。将其合并到已解决的阴影纹理中，或作为一个单独的通道进行渲染。
级联混合： 实现阴影级联之间更平滑的过渡，减少明显的边缘，增强整体视觉连贯性。
配置文件 在配置文件资产中轻松存储设置，可在运行时轻松交换或设置。
优化选项 可提高性能的高级选项，如循环和跳帧优化
