Custom PBR material

Recommended Posts

Hello everyone,

I've encountered a situation where I need to mix two normal maps for my PBR material. One map is the main texture while the second one is tiled detail texture. Much like Unity does with its standard material. What would be the best way to extend the functionality of the current PBR material (https://doc.babylonjs.com/classes/3.0/pbrmetallicroughnessmaterial or at least its PBRBaseSimpleMaterial parent). Amending shader itself and passing a second texture sampler is not a problem for me. I understand I should utilize material library and compile a new material. But should I use existing custom standard material as a basis or there are better ways of doing it? I would love to keep entire PBR shader code in local .fx files instead of replacing custom parts though. I bet many artists working with BJS have encountered similar issue where they'd need to tweak existing material and meddle with the shader code but the process of creating anything custom isn't that clear or intuitive. Any tips would be very helpful!

Many thanks in advance.

PS readme file for custom standard mat states that it would only work with BJS 3.0.0 and I'm using the latest stable one.

that is Simple PBR From CustomShader

u can make any channel for you pbr

 

** 

reflectPart = function( sampler Ref, nrm , scale ,   RefractiveParameter  , direction x , direction y , direction z , bias)

 new SB()

        .Map({path:'https://i.imgur.com/5b9To6N.jpg'}) 
         
         .InLine( reflectPart(
            'txtRef_0','nrm'
            ,0.005 ,-1,-1.,-1.,-1.,0.))
          

        .BuildMaterial(scene);

you can use shader string  for manage any parameter
