Enable SSAO2 post-processing, prompt information when rendering the scene code: ```auto let ssaoRatio = { ssaoRatio: 1, // Ratio of the SSAO post-process, in a lower resolution blurRatio: 0.5, // Ratio of the combine post-process (combines the SSAO and the scene) combineRatio: 1, }; ssao2 = new SSAO2RenderingPipeline("SSAO2RenderingPipeline", scene, ssaoRatio); // set 1，super jagged，set 4 resample； if (ssao2?._prePassRenderer) { ssao2._prePassRenderer.samples = 4; } } // Attach camera to the SSAO render pipeline if (scene?.postProcessRenderPipelineManager?.attachCamerasToRenderPipeline) { scene.postProcessRenderPipelineManager.attachCamerasToRenderPipeline( "SSAO2RenderingPipeline", [scene.activeCamera] ); } ``` when scene.render prompt this error ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/6/c/6c77fff5841c9371abea9b6d506b9960e23e0ecf.png) ---

I created an example, press f12 to open the console, click the 1 and 3 keyboard key repeatedly, and if you click several times, an error will be reported. This problem is not raised by me before. It is estimated that after this problem is solved, the code continues to execute to reproduce the problem I mentioned before. 1 or 3 repeat several times ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/0/7/07daa58f6e66a6d2e4c12f465db8853739bec683.png) > **[Babylon.js Playground](https://playground.babylonjs.com/#WGZLGJ%238543)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes ---

The repeated alternation between 1 and 3 works. It fails if you hit the 1 (or 3) twice in a row, because the PG does not take this into account.

Thank you for answering this question At present, this problem has seriously affected our project development. Please add an if judgment to deal with the abnormal problem and ensure the normal loading of the scene. When the full-screen reflective is used in combination with SSAO2, there will be false shadows This problem can be reproduced by first turning on the full screen floodlight and then turning on SSAO2 There is currently no PG post-addition ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/4/f/4fc9a293d5f8c6632c08ac82f3c52ded26bb9adb.jpeg) ---

Do you mean using SSR (“full-screen reflective”) and SSAO2 together does not work? It does work in this PG: > **[Babylon.js Playground](https://playground.babylonjs.com/#PIZ1GK%231224)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes If you can provide a repro in the Playground, it will be easier to help. ---

I can’t make a case for the above problem, because my problem appears in the project, and the operation is more complicated I did a case of a similar operation, but the result was different from what I expected. You can see what is going on here. I’ll try to make a case for this problem, looking forward to it ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/d/5/d5c7d5b5f1971b530d95fab70032cd6c108e6fdb.jpeg) Modify the parameter scene does not change > **[Babylon.js Playground](https://playground.babylonjs.com/#PIZ1GK%231228)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes first createSSAO2(); second createDefaultPipeline(); The result is different from the above ---
