![]() ![]() ![]() The output is either drawn to the screen or captured as a texture. More info See in Glossary to prevent Unity from drawing objects that are hidden behind other objects, reducing the far clip plane of a Camera A component which creates an image of a particular viewpoint in your scene. Consider using occlusion culling A that disables rendering of objects when they are not currently seen by the camera because they are obscured (occluded) by other objects. Perform more rigorous culling, so that Unity draws fewer objects.More info See in Glossary to create the effect of distant geometry. More info See in Glossary: for example, use a skybox A special type of Material used to represent skies. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. Consider reducing the overall number of objects in the scene A Scene contains the environments and menus of your game.You can reduce the number of objects that Unity renders.If this is the case, consider these options: ![]() Rendering commands include draw calls (commands to draw geometry), and commands to change the settings on the GPU before drawing the geometry. Usually, the greatest contributor to CPU rendering time is the cost of sending rendering commands to the GPU. If you are not yet familiar with this subject, read the article before following any of the advice on this page. The following article on the Unity Learn site is a comprehensive introduction to graphics performance, and contains information on identifying and fixing problems: Fixing performance problems. Strategies for fixing these problems are quite different, so it’s important to understand where your problem is before taking any action. Additionally, rendering-related performance problems can occur on the CPU or the GPU. If you attempt to solve a performance problem before you understand its cause, you might waste your time or make the problem worse. Before you begin: locate and understand the problemīefore you make any changes, you must profile your application to identify the cause of the problem. Here's hoping that Unity continues to make advanced graphical effects available in its basic package so that Unity games continue to be less and less identifiable at a glance.This page contains some simple guidelines for optimzing rendering performance in your application. Put together, these built-in effects can add quite a bit of personality to demos without the need to invest a lot of time and resources into customization. Then there's tonemapping color grading (which Meijer called "Instagram for games") that lets developers play with the color tinting on various shadows, midtones, and highlights in a scene. ![]() In an on-stage demo at the Game Developers Conference, Unity Technical Director Lucas Meijer took us through some real-time tweaks of an impressive 3D animation called Adam, showing how developers can take a flat-looking scene and spice it up automatically with these heavily customizable effects.Īmbient occlusion, for instance, adds more shadows to places that light sources struggle to reach, while depth-of-field adjustments can make objects look blurrier as they get closer or farther from the in-game camera's sweet spot. More recently, Unity has also introduced an impressive suite of Cinematic Image Effects, which allow for easy introduction of some complex graphical tweaks inside Unity with a few clicks and sliders. You can also see significant improvements in things like diffuse reflections off of surfaces. The version 5.4 beta also lets developers easily alter the size and properties of water effects, so things like water, smoke, and sparks look less generic between Unity games. That has allowed developers to move light sources around during gameplay, rather than using the pre-baked lightmaps that need to stay static regardless of the in-game situation. Chief among these effects was the Unity 5.0 introduction of Enlighten real-time global illumination. ![]()
