Map repeat affecting other textures' repeat on material

[daveo1001]

plunker

When setting the map to repeat the alphaMap is also affected.

I'm expecting each face of the cube to have a giant whole in the middle with the edges of the taco time texture showing near the edges of the cube in a 3x4 pattern.

I'm getting the 3x4 pattern of the taco time texture but the alphaMap, although it does not repeat it does scale down to the size of the other map. It also produces some nasty streaks.

If you comment out line 35 material.map.repeat.set(3,4); you can see what I'm expecting from the alphaMap.

Changed my mind. We can consider this a feature request.

Thanks! I would throw money at someone to allow me to have different repeats.

@WestLangley : What you are seeing is a current "feature" of three.js: only one offset/repeat pair is allowed per mesh. mesh.map has priority.

That's not quite true.
Example: http://necromanthus.com/Test/html5/SMC.html
The terrain is using the DiffuseMap and LightMap with different UV coords (offset/repeat).

[WestLangley]

@mrdumb Both lightmap and aomap use the 2nd set of UVs and do not support a custom offset/repeat setting, defaulting to [ 0, 0 ], and [ 1, 1 ].

We also are hoping to do the same with map (repeat 1,1) and bumpMap (repeat N,N) in StandardMaterial. Linking a related pull request: #8278

UV coords per texture layer is a must in any decent 3D engine.

What's your point?

I thought it's obvious.
In that example you can see repeat = [3,4] for the LightMap.
So you are wrong ...

[WestLangley]

@mrdumb As I said, map.repeat is [ 1, 1 ] for lightMap and aoMap because it is hard-coded. In your example, you have modified the 2nd set of UVs.
