Module material_graph 

Node-based materials. A material is a graph of small nodes (textures, colours, maths, noise, gradients…) saved as a .kmat file; to_wgsl turns it into a fragment shader that the renderer compiles like any other custom shader. Drop a .kmat file on a model to use it.

Every socket carries a vec3 (a number is spread over all three channels), so any output can feed any input. The three texture slots of a material (albedo, normal, ORM) are bound for the “Texture” node.

use kvas_engine::material_graph::{MaterialGraph, to_wgsl};
let graph = MaterialGraph::default_graph();
let wgsl = to_wgsl(&graph).unwrap();
assert!(wgsl.contains("fn fs_main"));

Structs

MatNode

A node of the graph.

MaterialGraph

A whole material.

NodeSpec

Static description of a node type.

Socket

One input socket of a node.

Enums

GraphMode

What a graph produces.

Constants

SPECS

Every node type.

Functions

all_specs

Every node type of both lists.

available

Whether a node type can be used in a graph of this kind.

is_output

True for the three result nodes.

spec

Looks a node type up by name.

to_wgsl

Generates the shader of a graph (the prelude and the library functions are added by the renderer): a mesh shader for materials and shaders, an effect function for camera effects.
