Linear color space rendering doesn’t have fallback support for WebGL 1.0. Unity WebGL only supports linear color space rendering with WebGL 2.0. Lightmaps are overlaid on top of scene geometry to create the effect of lighting. In addition, Unity WebGL supports Non-Directional lightmaps A pre-rendered texture that contains the effects of light sources on static objects in the scene. See in Glossary isn’t currently supported in WebGL. Realtime Global Illumination A group of techniques that model both direct and indirect lighting to provide realistic lighting results. Lights themselves are also treated differently by Forward Rendering, depending on their settings and intensity. On WebGL 1.0, Unity WebGL runtime falls back to Forward Rendering A rendering path that renders each object in one or more passes, depending on lights that affect the object. Unity WebGL only supports Deferred Rendering Path if WebGL2.0 is available. To do this, set webglContextAttributes.preserveDrawingBuffer to true in your WebGL template: script.onload = () => However, you can change this behavior at instantiation time. Camera clearīy default, Unity WebGL clears the drawing buffer after each frame, which means the content of the frame buffer clears regardless of the Camera.clearFlags setting. WebGL 1.0 roughly matches OpenGL ES 2.0 functionality, and WebGL 2.0 roughly matches OpenGL ES 3.0 functionality. More info See in Glossary is an API for rendering graphics in web browsers, which is based on the functionality of the OpenGL ES graphics library. The Unity WebGL build option allows Unity to publish content as JavaScript programs which use HTML5 technologies and the WebGL rendering API to run Unity content in a web browser. WebGL A JavaScript API that renders 2D and 3D graphics in a web browser.
