NodeMaterial PMREM custom size

[sunag]

Custom PMREM texture size per node.

Example

256

1024

With this approach is possible to create multiples PMREMs for the same material each with different sizes.

[sunag]

Usage

nodeTexture = new THREE.TextureNode( pmremCubeUVPacker.CubeUVRenderTarget.texture );
nodeTextureSize = new THREE.FloatNode( 1024 );

nodeMaterial.environment = new THREE.TextureCubeNode( nodeTexture, nodeTextureSize );

Thanks!

[WestLangley]

@sunag Thanks for this. Please see webgl_materials_envmaps_hdr.html for how to modify this example to properly support modules.

[sunag]

@WestLangley Apparently to this is possible is necessary makes this changes #16054

[WestLangley]

@sunag I do not think you should be referencing the THREE namespace in your example. import the classes you need.

@Mugen87 Correct?

[sunag]

For this is necessary some changes in /nodes/ code, remove all THREE namespace dependencies that exists there.

@WestLangley I'm actually changing that. Making the examples import the THREE namespace. Makes the development experience nicer (basically how it was before).

EDIT: I'm referring to the html files and not the files in /jsm.
