Why doesn't this GLB export have transparency?

[MEATTAIL]

Hey!

I’m working with a character that has translucent parts. I’m trying to export the final result as a GLB. Note that some parts of its texture are translucent:

Typically the solution is to set the material’s blend mode to “alpha clip”. However, this doesn’t seem to work in this case:

Instead, the “alpha hashed” blend mode gives me the results I’m looking for:

I’m not sure why this is, as I’ve always used “alpha clip” when it comes to transparent textures.

When I try to export the model as a GLB with the blend mode set to “alpha hashed”, the normals appear flipped, and the character’s eyes look as if they’re in front of everything:

…And when I export it with the blend mode set to alpha clip, the helmet is completely opaque:

Why is this? How can I get the GLB export to look like the blend file set to alpha hashed?

You can find the project files here! Thank you!

What about alpha blend?

I get practically the same results as exporting with the blend mode set to “alpha hashed” as I do when the blend mode is set to “alpha blend”, except the flipped normals and bulging eyes are also visible in Blender’s 3D viewport:

Here’s what the GLB export looks like:

Resolved this! I just had to make a separate material for the translucent parts.

I cloned the original material, changed the blend mode to “Alpha Hashed” on the new material, and set the blend mode to “Alpha Clip” on the original material.

Here’s the result!
