Unity custom msaa resolve. There is no solution to this yet for Unity.

Unity custom msaa resolve com Mar 14, 2024 · I’m working on a sobel render feature but enabling msaa causes color artifacts. However, my current implementation only returns a value for sample index 0, and so I suspect that I am missing some step that will help me access an unresolved depth texture. Feb 22, 2017 · Graphics. About the resolve on “destination”, I doubt if that is truly necessary. Nov 12, 2023 · Hello, I am doing some simple tests to read back multi-sample data from the depth texture. Blit->RenderTexture. Feb 9, 2021 · I’ve started looking deeply at how dynamic resolution and MSAA work together. x there was a big optimization push for mobile and Tex2DMS sampling capability has been added, so it is now possible to resolve MSAA depth implicitly in the copy depth pass. All tests were done using 1 camera in a very basic scene (skybox + 2 primitive meshes), on an iPhone X. May 19, 2018 · The second issue is how the MSAA resolve works is by averaging the values of the multi-samples. While the box filter works well enough, it has some characteristics that can be considered undesirable for a reconstruction filter. If the source texture has MSAA /// enabled, the pass uses a custom MSAA resolve. MSAA helps a ton for color, but for the depth normals the box blur MSAA messes it up. Is there anyway to disable this resolve, or apply a custom MSAA resolve shader in unity? Maybe potentially with a native plugin Nov 13, 2016 · If you want to implement MSAA (multisampled antialiasing) rendering, you need to render into multismpled render targets. Nov 13, 2016 · If you want to implement MSAA (multisampled antialiasing) rendering, you need to render into multismpled render targets. As a high level breakdown the render feature is doing the following: Renders the vertex colors of objects to a render texture. You can look up inverse tone mapping and custom MSAA resolve if you want to read more about it. I was recently investigating why I was getting very poor anti-aliasing around all the windows looking outside and on some areas of the exterior of the scene. Tile-based GPUs may get performance advantage if the store action is DontCare. ResolveAntiAliasedSurface method but I don’t know if that’s the solution/how to use it. When you want to read an anti aliased rendertarget as a shader resource, first you need to resolve it. Please note that not all platforms have load/store actions, so this Jul 28, 2017 · However Unity does not use or have support for custom resolves as it does not support directly sampling a multi sampled buffer pre-resolve. If the source texture Feb 12, 2023 · By default Unity will resolve an MSAA render texture so it can be sampled like a normal texture, though the latest versions have added support for subsample sampling that avoids that extra step (though it means you have to do the resolving yourself if it’s wanted if you choose to enable that option). I then came across this old blog post See full list on github. Nov 27, 2024 · This seems to be because in Unity 6 Depth Priming Mode is forced disabled when MSAA is enabled. Here is the simple cs program that prints out pixel data for four sample indices for a single pixel from the depth texture: public Apply MSAA to enhance the rendering of edges with custom resolve options and immediate and tile-based resolve paths. Almost When the GPU is done rendering into a render target, this setting specifies the action that should be performed on the rendering results. /// so you can use it later in rendering. The resolve on “source” is unavoidable, because you need to multisample your render result to get the rendertexture your camera just rendered. 2x MSAA appeared to take 0. MSAA is more resource intensive than other forms of anti-aliasing on most hardware. The only reason why the depth prepass was forced in previous version when MSAA was enabled was the lack of MS sampling capability. However, when I declare my Texture2DMS in my shader, I get the following error: Oct 29, 2012 · Despite having the flexibility to implement a custom resolve for MSAA, the “standard” box filter resolve is still commonly used in games. There is no solution to this yet for Unity. 3 both could be enabled. ResolveAA will occur on both “source” and “destination” because their antialiasing type. I’ve done some profiling, and without dynamic resolution, there is little difference in GPU frame time between MSAA or 2x MSAA. As you noted, all MSAA buffers are resolved to a non-MSAA texture before a shader gets a chance to sample it. When I turn off MSAA and ensure Depth Priming is enabled, the problem goes away (but without MSAA things look terrible). I see there’s a cmd. Apr 21, 2017 · I am trying to access/resolve the MSAA Render Texture/Target in a custom fullscreen pass / image effect. Runs a sobel filter over the vertex color texture and composites Apr 13, 2017 · Use case: Manifold garden spits out a color and depth-normals buffer (used for edge detection) in one MRT pass. Oct 7, 2025 · Hi, I’m fairly new to Unity, I have an interior scene with a bright exterior that uses auto exposure in URP (from the asset store) and that relies of MSAA for anti-aliasing (it’s a PCVR project). In 2022. 03 ms more at most after several tests. If one of the samples is way over 1, like the ground, then the average gets pushed above 1 too removing the effectiveness of the MSAA. MSAA is a hardware anti-aliasing method. The box blur MSAA resolve doesn’t work out well for depth/normals. For example, this setting can be useful if the depth buffer contents are not needed after rendering the frame. in 21. VictorKs: Nov 12, 2020 · I don’t understand why. . Contribute to ryanKeable/Tonemapped-MSAA-Resolve development by creating an account on GitHub. However, when run on a tiled GPU with no post-processing anti-aliasing or custom render features in use, MSAA is a cheaper option than other anti-aliasing types.
