![]() You can do this by enabling Customized UVs, connecting nodes to them and then in the pixel shader using a Texture Coordinate node to target the customized UV. ![]() Placed lighting should not be used in your scene when depending on maximum performance.Ĭonsider performing as many operations in the Materials Vertex Shader as possible. Make sure all of your Materials have their shading model set to Unlit for maximum performance. Post Processing Feature are unavailable in this mode. In most cases, this will require you to author your translucent textures and Materials differently than you would in HDR or for a normal PC title. Translucent primitives are blended in gamma space. The scene's color is written out in gamma space with each color channel clamped to the range of. Still provides full access to the Material Editor for defining custom shaders and even performing simple shading that can be used to fake lighting. Provides the fastest and lowest overhead mode available for mobile devices, which enables your game to run well on slower mobile devices. ![]() To use this mode, you must disable Mobile HDR for your project in the Rendering section of the Project Settings. Low Dynamic Range (LDR) mode is the lowest performance tier supported in UE4 and is recommended for games that do not require lighting or Post Processing features. Check the compatibility page under iOS Development and Android Developmentįor more information on what devices have been tested here at Epic and which tiers we think are most appropriate for that device. Use based on the quality of graphics your game requires and the types of devices you need to support. When building a mobile game, you should decide which features to Possible to mix and match most of UE4's mobile lighting features, it can be useful to categorize these features into the following tiers. Using these features costs performance and may cause your game to perform poorly on slower mobile devices. Unreal Engine 4 (UE4) supports a variety of lighting features on mobile devices. You will also find some suggestions to keep in mind for any project you work on that will This includes developing with a specific lighting tier to get the most out of performance on aĭevice and why a particular lighting tier may work best for your target audience. List of devices you want to release your title for.
