Making mesh invisible for the camera but still available for ReflectionProbe

[Evgeni_Popov]

The PGs in this thread are doing the blur with a post process (but it’s not a cube texture):

PBR Refraction roughness (blurriness)

Since 5.0, postProcessManager.directRender() is taking a RenderTargetWrapper instead of an InternalTexture as the output object (change in line 153): I don’t really remember how we ended with this PG, but if you found an easier way to achieve what you want all the better!

In the same thread, using a cube texture (probe):

PBR Refraction roughness (blurriness)

You need to enable generation of mipmaps for the probes, as well as adding a reflection texture (env map - see line 4), else the realtime filtering feature is not enabled: https://playground.babylonjs.com/#22KZUW#274 I have also enabled the local cube map feature on the refraction textures (by setting the boundingBoxPosition and boundingBoxSize properties), as it is a little better.
