MeshStandardMaterial not working properly with alpha ,normal and roughness maps when rendering

[nightfury07x]

Describe the bug

I have threejs mesh with MeshStandardMaterial that have alpha,normal and roughness maps added to the material with repeating and wrapping

alpha.wrapS = THREE.RepeatWrapping; alpha.wrapT = THREE.RepeatWrapping;

Material.alphaMap?.repeat.set(1 / scale, 1 / scale);

But when rendering the object these maps are not showing in correct scale but the base texture apply with correct repeat and scale

Expected behavior

when rendering other maps should be scaled and repeated correctly as the base texture in the material

Screenshots and Repro Model

before the render how alpha map is working (can see the transparent windows are placed correctly)

when rendering (base texture placed correctly but windows are very small are wrongly placed )

gltf model than exported from the scene blocks.zip

Your model does not include an alpha map...

@gkjohnson I think when exporting the gltf alpha map is did not attached to the material here is the alpha map I have used

I'm sorry, I need you to provide a model or working example. I cannot spend my time figuring out the right way to textures to your models in order to reproduce your problem.

Closing until a working example that demonstrates the problem is provided.
