![]() More info See in Glossary and change the Cast Shadows property to Two Sided. ![]() A potential solution is to open the GameObject’s Mesh Renderer A mesh component that takes the geometry from the Mesh Filter and renders it at the position defined by the object’s Transform component. In some situations, Normal Bias can cause an unwanted effect called “light bleeding”, where light bleeds through from nearby geometry into areas that should be shadowed. Likewise, setting the Normal Bias value too high makes the shadow appear too narrow for the GameObject: A high Normal Bias value makes the shadow shape too narrow A high Bias value makes the shadow appear “disconnected” from the GameObject This results in a disconnected shadow, making the GameObject look as if it is flying above the ground. More info See in Glossary window when shadows are enabled.ĭo not set the Bias value too high, because areas around a shadow near the GameObject casting it are sometimes falsely illuminated. ![]() More info See in Glossary, you can set these values with the Bias and Normal Bias properties in the Light Inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. Unity lets you choose from pre-built render pipelines, or write your own. In the Built-in Render Pipeline A series of operations that take the contents of a Scene, and displays them on a screen. You can add a bias to the distance in the shadow map to ensure that pixels on the borderline pass the comparison, or you can inset geometry a little bit along its normals. To prevent shadow acne, you can adjust the light bias settings. Shadow acne in the form of false self-shadowing artifacts The result is arbitrary patterns of pixels in shadow when they should be lit, giving a visual effect known as “shadow acne”. This is because pixels that should be exactly at the distance specified in the shadow map are sometimes calculated as being further away (this is a consequence of using shadow filtering, or a low-resolution image for the shadow map). Shadow acneĪ surface directly illuminated by a Light sometimes appears to be partly in shadow. More info See in Glossary underneath your characters, or can create blob shadows with custom shaders. More info See in Glossary or quad A primitive object that resembles a plane but its edges are only one unit long, it uses only 4 vertices, and the surface is oriented in the XY plane of the local coordinate space. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. ![]() Unity supports triangulated or Quadrangulated polygon meshes. Meshes make up a large part of your 3D worlds. If this is too resource-intensive, you can fake shadows using a blurred texture applied to a simple mesh The main graphics primitive of Unity. More info See in Glossary meshes or even primitives to cast shadows. If rendering real-time shadows for complex geometry is prohibitively expensive, consider using low LOD The Level Of Detail (LOD) technique is an optimization that reduces the number of triangles that Unity has to render for a GameObject when its distance from the Camera increases. Soft shadows have a greater rendering overhead than hard shadows, but this only affects the GPU and does not cause much extra CPU work. More info See in Glossary that might cast shadows must first be rendered into the shadow map and then that map will be used to render objects that might receive shadows. A GameObject’s functionality is defined by the Components attached to it. Real-time shadows have quite a high rendering overhead any GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more.
