You can use a second camera to render the meshes that should not receive SSAO and use the technic described in this post to make it work:

> Here’s how to make it work with the current Babylon.js codebase (MSAA not fully supported): You need to create the depth/stencil texture for the Edge post process, so that the depth can be shared with the 2nd camera: postProcess.onSizeChangedObservable.add(() =\> { if (!postProcess.inputTexture.depthStencilTexture) { postProcess.inputTexture.createDepthStencilTexture(0, true, false, 4); postProcess.inputTexture.\_shareDepth(rtt.renderTarget); } }…
