MToon Scrolling Texture Rendering Bug

[tdw46]

I've a VRM with a few planes and a transparent MToon scrolling texture on them. In any Unity VRM app it appears like so:

However, in three-vrm based viewers, I get no visual on these scrolling textures:

Attached is a test VRM with only this steam mesh included (for IP reasons). Can you please investigate? Let me know if you need anything else!

I just checked the model you shared; it shows the mesh if I increase the mesh's alpha.
It seems there is something different around the alpha blending procedure between UniVRM/Unity and three-vrm/Three.js.

It appears that you are cascading so many meshes to achieve the steam mesh. Could you try reducing the mesh and increasing the alpha?

If I apply a post-processing using EffectComposer, it renders. I'm 90% sure it's an issue that comes from the precision of the screen buffer.
