Hi there,

On the following image the interior shade of the base cabinet is applied to the front of door center panel. When I remove affected cabinet the wrong shade reappeared on the next one.

This issue is reproduced on the playground  
[[https://www.babylonjs-playground.com/#WGZLGJ#648](https://www.babylonjs-playground.com/#WGZLGJ#648)]([http://Playground](http://Playground) example)

Any advise will be appreciated,  
Thanks

Maybe @julien-moreau has an idea?

Hi @val!  
I notice that the geometry buffer renderer (used by the SSAO pipleine) doesn’t render the door as you can see in the normals:

I’m testing if there is any alpha or whatever but I find nothing at the moment ☹

Ok found, the material’s albedo texture has the flag “hasAlpha” set to “true”.  
Then, it will not be renderered as geometry buffer renderer will render only opaque and alpha-test meshes. Here the material needs alpha blending.

Fixed here: [https://www.babylonjs-playground.com/#WGZLGJ#657](https://www.babylonjs-playground.com/#WGZLGJ#657)  
Maybe you can re-export by deleting the unnecessary alpha flag on the albedo texture (that looks to have no alpha)

Hope that helps 🙂

Yes, that is it! Thank you @julien-moreau for your help!
