Note: If you try to move the “InitializeAndroidSurface” from Update method to “Start” method, the solution will fail since the Start method doesn’t run in a render thread. Here’s the correct plug-in snippet private void initSurface() So, the right approach is to initialise the SurfaceTexture when the correct OpenGL context is active. Most of the plug-in calls are made from coroutine threads created by Unity and doesn’t have the correct OpenGL context and hence they fail. The reason being, the creation of SurfaceTexture need to happen in the render thread and when the correct OpenGL context is active, which is not the case always. However, the whole texture is just showing up on the plane and not updating whatsoever. I have created a texture to test this and have tried setting two update zones to change on runtime. But the SurfaceTexture created like that doesn’t work. In part 1, we started understanding Render Textures and used them to create an in-game tv-camera read the 1st part here: Unity features 101: Render textures part 1 (in-game tv-camera).In this. I am currently trying to create an old style computer screen on one of my objects in my game and am using render textures to do so. Unity stylizer with render texture android#In order to successfully create an Android SurfaceTexture from Unity, all that you need is the texture pointer which can be obtained as mentioned above. You can get the underlying native OpenGL texture pointer using “GetNativeTexturePtr” method like below _imageTexture2D = new Texture2D(1280, 800, TextureFormat.ARGB32, false) _nativeTexturePointer = _imageTexture2D. Before we proceed to the solution, please make sure that the “Multithreaded Rendering” is disabled in Player settingsĬreating Unity texture is simple. First, we will see the Single threaded rendering model and later on extend the solution for multithreaded rendering. The rendering itself can be “Single” or “Multithreaded rendering”. We all know that Unity uses multithreading to support coroutines. The key to the solution is to understand how OpenGL and Unity Rendering works. ![]() In this article we are going to see a fool proof and simple optimised mechanism to update the texture created by Unity from android. Some of them are resource intensive as they tend to draw or copy the content from render buffer which is ineffective. Some of the approaches which does work, are kind of hacks and they are bound to break. It would break if the Unity version changes or if the Android version changes. Not many people got it working the right way. Unity stylizer with render texture for android#One of the difficulty faced in plug-in development in Unity for android is the ability to update or modify the content of Unity texture from Android plug-in code. M圜amera.External texture rendering with Unity and Android You can set the Output Target for a Camera in a script by setting the cameraOutput property of the Camera's Universal Additional Camera Data component, like this: myUniversalAdditionalCameraData.cameraOutput = CameraOutput.Texture The second Camera renders the Scene including the Render Texture to the screen. The first Camera renders its view to the Render Texture. Place the Quad within the view of the new Base Camera. Its Render Mode defaults to Base, making it a Base Camera. Set the Camera’s Output Target to Texture, and drag the Render Texture on to the Texture field.Ĭreate another Camera in your Scene. In the Inspector, scroll to the Output section. ![]() In the Scene view, drag the Material on to the Quad.Ĭreate a Camera in your Scene. In the Inspector, drag the Render Texture to the Material's Base Map field. Rendering to a Render Texture, and then rendering that Render Texture to the screenĬreate a Render Texture Asset in your Project using Assets > Create > Render Texture.Ĭreate a Material in your Project, and select it. For more information on Camera rendering order in URP, see Rendering order and overdraw. This ensures that the Render Textures are ready to render to the screen. In URP, all Cameras that render to Render Textures perform their render loops before all Cameras that render to the screen. Unity stylizer with render texture full#If you have a Camera that is rendering to a Render Texture, you must have a second Camera that then renders that Render Texture to the screen. Stylizer Extended contains full featured Stylizer plugin, but it also provide you with super useful additional contents, such as 68 color palettes, 10 patterns presets & Demo content that comes with four environments which contains more than 70+ models & 16 scenes to show you the full potential of Stylizer. Rendering to a screen is the default and is the most common use case, but rendering to a Render Texture allows you to create effects such as CCTV camera monitors. In the Universal Render Pipeline (URP), a Camera can render to the screen or to a Render Texture. ![]()
