Hi everybody,

I’m trying to put an image with the text as a map of a MeshBasicMaterial applying it to a Cylinder.
My problem is that when I apply a Y rotation on the mesh, an inner part of the map is hidden.

Some screenshot of the issue:

for the real online example the link is: https://codesandbox.io/s/m338zplo2p

In the demo I just see this:

Have you fixed the issue, or what should we be looking for?

no, i’m sorry,

maybe something went wrong with the save of the codesandbox,
now I hope, you can see it: https://codesandbox.io/s/m338zplo2p

I can’t see any preview at that link (error: OrbitControls is not a constructor), but based on your screenshot you probably want to be keeping transparent: false and instead setting alphaTest: 0.5 (or some other value 0-1). See https://threejs.org/docs/#api/en/materials/Material.alphaTest.

thank you so much.

replacing transparent: true with alphaTest: 0.5 I solved that issue!
