Sending multiple texture maps to a fragment shader

[williamsma]

Coming from a WebGL background and new to PIXI.js, so I am used to sending multiple texture maps to a single Fragment Shader.

I sense PIXI.js framework sends a default texture map to the fragment shader, but found little on sending multiple texture maps to a single Fragment Shader.  Perhaps this is a restriction of the Framework.

My question is how to send multiple texture maps to a single Fragment Shader.  Is there a simple example of this?  

Appreciate any pointing in the right direction.

https://github.com/pixijs/pixi-picture uses two textures: one is copy of framebuffer under object, the second is the object itself. As a result, we can use OVERLAY blendMode in webgl

Ok, thanks much for the response.  I'll take a look at it.  Are there any .js file(s) I should focus on?

Here is an example of a filter in the lib that lets you specify a texture: https://github.com/pixijs/pixi.js/tree/master/src/filters/displacement
