Babylonjs scene optimizer. Optional improvementMode: boolean defines if the scene optimizer must run the maximum optimization while staying over a target frame instead of trying to reach the target framerate (false by default) Parameters scene: Scene defines the current scene where to apply this optimization optimizer: SceneOptimizer defines the current optimizer Jun 18, 2018 · brunobg commented on Nov 16, 2021 Bug is closed, but this is still happening. HighDegradationAllowed ()” My expectation Scene with large number of meshes If you have a large number of meshes in a scene, and need to reduce the time spent when adding/removing those meshes to/from the scene, There are several options of the Scene constructor that can help : Setting the option useGeometryUniqueIdsMap to true will speed-up the addition and removal of Geometry in the Feb 18, 2020 · The scene optimizer is great for auto-merging meshes, reducing shadow quality and material properties, but in your case the low FPS is coming from the number of meshes (which cannot be merged, i assume, as you need them all to move freely). Sep 17, 2025 · From what I can tell, Babylon. To start using the SceneOptimizer, you can create a new BABYLON. The SceneOptimizer constructor requires the current scene and a BABYLON. SceneOptimizerOptions object (we will get back to it later): // Optimizer var optimizer = new BABYLON. The scene is somewhat like the stage on which all the meshes are placed to be seen and the cameras and lights are placed that make them viewable. Jan 26, 2025 · So I have a setup with the scene optimizer, that once its reaches it FPS target it waits a few seconds then restarts the optimizer in improvement mode. Rendering a scene on a browser is a great experience because you can reach a lot of different users and hardware. I was under the impression that if you are hitting your FPS marks that the improvement mode will try to step up the optimizations instead of degrade. But in practice I’m not seeing it. com), and there is also the Scene Optimizer who can do some of the work automatically: The Scene Optimizer | Babylon. babylon file from Maya Jun 23, 2022 · And for scene optimization, some strategies have to be done manually (as we wouldn’t be able to always make the correct assumptions when optimizing) Optimizing Your Scene | Babylon.

Use meshes only when associated with content to render. When creating the SceneOptimizer you can provide the following parameters: This tutorial will help you find some links and info on how you can improve your scene regarding rendering performance. I will throttle my fps to lets say 10 and have a target . Use TransformNode instead of AbstractMesh or empty meshes If you need node containers or transform nodes, do not use meshes but TransformNode instead. js SceneOptimizer only kicks in based on FPS thresholds, which isn’t really what I want. js Documentation So, for instance if, the target FPS is 60, the optimizer will execute all optimizations in its list while the FPS remains at 60. But the main associated caveat is that you can encounter very low end devices. It is a good tool to provide rendering improvements to a given scene. To start using the SceneOptimizer, you can create a new BABYLON. Of course there are more than meshes, cameras and lights that make a scene a good experience for your users, for example the user interface. It happens here with: load a gltf drop some meshes merge some other meshes (not the dropped ones) turn on the scene optimizer My guess is that the scene optimizer is loaded before the GLTF and there's a race. But the main associated caveat is that you can encounter very low-end devices. The SceneOptimizer tool is designed to help you reach a specific framerate by gracefully degrading rendering quality at runtime. The meshes need to go through an Mar 28, 2023 · I’m fairly new to Babylonjs so I’m sure there are a lot of things I can do to optimize. By default it will try to reach a specific framerate but if the optimizer is set with improvementMode === true then it will run all optimization while frame rate is above the target frame rate Useful links Official web site: www. js Documentation From the document above it seems as though I should just be able to call without having knowledge of grids, datakinds, etc: “BABYLON. However, this bug ticket is about the SceneOptimizer. babylon file from 3DS Max Maya exporter can be used to generate a .
