NodeMaterial and structured uniforms

miko3k · July 26, 2020, 5:47pm

Structured uniforms should be supported in three.js. NodeMaterial is based on ShaderMaterial, therefore it should support them as well.

https://threejs.org/docs/#api/en/core/Uniform

however, NodeBuilder seems to emit uniforms before the structure definition, therefore GLSL has no chance of compiling…

			this.attributes[ name ] = { varying: varying, name: name, type: type };

		}

		return this.attributes[ name ];

	},

	getCode: function ( shader ) {

		return [
			this.prefixCode,
			this.parsCode[ shader ],
			this.getVarListCode( this.getVars( 'varying' ), 'varying' ),
			this.getVarListCode( this.inputs.uniforms[ shader ], 'uniform' ),
			this.getIncludesCode( 'consts', shader ),
			this.getIncludesCode( 'structs', shader ),
			this.getIncludesCode( 'functions', shader ),
			'void main() {',
			this.getVarListCode( this.getVars( shader ) ),
			this.code[ shader ],

is this a feature or a bug?
