    I’ve got a problem with material export from Blender 4.2 + Verge 4.7.1
    Normal Map node uses UV layer, which was manually selected in the mesh data tab, but not the one specified in node’s settings.

    “Sad smile” from the right of attached picture is incorrect UV layer export (sneak peek)

    Just do not use the NormalMap node without Shader nodes (Principled, Diffuse, whatever). Normal output is not supposed to be connected to Surface input. And your scene has no lights to see your normals…

    And keep in mind that Blender and Verge3D are two big differencies.

    Puzzles and JS coding. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

    This is just stripped example to explore the problem.
    It doesn’t work no matter what lights or shaders are used, I stil get wrong UV layer for Normal Map tangents.

    Unwrap the second UV (even with different scale or shape) and it won’t be a problem. Looks like a point UV is the culprit. And yes, manually selected UV somehow affects the result in V3D.

    Hi,
    We managed to figure out why it’s happening. The fix is on the way!
