Map and animated alphaMap

Questions
1

Hi,

if I have a material with an alphaMap like:

material.alphaMap = alphaMap;
material.alphaMap.magFilter = THREE.NearestFilter;
material.alphaMap.wrapT = THREE.RepeatWrapping;
material.alphaMap.repeat.y = 1;

and then animate the alphaMap like:

material.alphaMap.offset.y += 0.002;

…everything is fine when my material “just” uses a color like:

    let material = new THREE.MeshStandardMaterial({
      color: 0xff00ff,
      transparent: true, alphaMap:myAlphaMap,
      side: THREE.DoubleSide,
      flatShading: true,
      alphaTest: 0.5,
    });

As soon as my material uses a map instead of a color, the animation is “gone”:

    let material = new THREE.MeshStandardMaterial({
      map:mymap,
      transparent: true, alphaMap:myAlphaMap,
      side: THREE.DoubleSide,
      flatShading: true,
      alphaTest: 0.5,
    });

Isn’t it possible as to have a map sort of masked by an animated alphaMap?

You are hitting a current restriction of the engine. The respective issue is:

Ah!

Ok, so the conclusio would be, if I´m not repeating the map, it should work?

Nope, since as soon as map is configured, the renderer will use its texture transformation.
