Rim Effect

[pichou]

HI everybody!

Is it possible to add a rim effect on mesh like in this image :

 

Thanks, Pichou

We do

here is an experiment: https://www.babylonjs-playground.com/#H82GNB

Cool I didn't know about the fresnelParameters!

To go further, do you think there is a way to mix waterMaterial with the fresnel parameters to obtain a sort of force field? 
Something like that : https://www.youtube.com/watch?v=tB5WoFpWdYQ (hope I won't get ban for sharing a unity video  )

 

I have made a test in this playground with no result : http://www.babylonjs-playground.com/#1SLLOJ#386
But maybe the waterMaterial is not the right tool to do that.

Cheers!

We are getting closer to a custom shader here

But still, I guess we can use StandardMaterial flexibility like this:

Yep that was what I thought, but I don't have the time right now to get into custom shader.

But I have some idea now to get close to what I need thanks to your suggestions.

I have this force field custom shader in my favorite, I worked on it long time ago: http://cyos.babylonjs.com/#15MS95

Hope it can help!

Hi @Temechon!

I am currently tring to add you force field custom shader in my scene (which looks really great by the way!)

But I need the force field to be also transparent. Do you a way to do that? I am just starting with custom shaders so don't really know all the parameters yet!

Thanks, Pichou

I made it work by adding the needAlphaBlending: true attribute in the ShaderMaterial creation! It looks really nice!

Weird thing I noticed though : If my mesh with the shaderMaterial has a visibility of 1, it creates a hole in the canvas. I mean I can see the other html element behind the canvas in the scene.
In order to avoid that I add to put the visibility to 0.2.

ShaderMaterial are awesome, I will continue to add them in my scene!
