Shadows and mirroring


Recommended Posts

Hi everybody,
I'm looking for a way to get a ground in my scene with the same exact color of the background (scene.clearColor), that reflects the meshes above it and that displays shadows casted by a light on receiving objects.

I tried to use EnvironmentHelper to get this result but I always have a halo on the ground, see the following playground:


Is there a way to avoid that halo so that the color of the ground is the same as the background? I don't want the user see the ground at all, I only want shadows and mirroring.

I tried also to use the BackgroundMaterial directly but without success (see playground)


I tried then to create the ground and the materials by hand but as in the following playground, but I have a problem to show shadows and reflections at the same time. 
Also, to get the same color of the background I set gammaSpace to true on the MirrorTexture but I get a reflection too dark (and no shadows).


I saw that exists ShadowOnly material that shows only shadows. Is there a similar material with mirroring too?

Any suggestions are welcome,

Hi Matdav !

One solution could be to use 2 different meshes as ground :
-> 1 to display shadow only, using the shadowOnlyMaterial.
-> 1 to display reflection only, using a material with mirrorTexture and without diffuse or specular attributes

You can see a PB of this solution here https://www.babylonjs-playground.com/#QHN8ZT

Of course, there may be a more efficient way, perhaps by using a single one couple mesh and material... 

Have fun !
