    Hello there !

    I’m using Physical material for some objects (lightbulb), and i’d like to be able to change transparency, as for some coloured lights, the bulbs are no more transparent, but opaque glass.

    I can’t figure-out how to expose the transparency param to verge3D :
    tried all this in 3DSmax:
    – controller in the transparency slot;
    – RGBA controler in the transparency color slot;
    – colormap in the transparency color slot;
    – bitmap in the transparency color slot;
    – set an animation key;

    …and this in verge3D puzzles :
    – change bitmap or set value or set color… Transparency is not in the list…
    – use flexible input mode to force “transparency” value

    No way.

    I could also use 2 different shaders, but as the material is in a multi/sub one (because i need the lightbulb to be attached to the other parts, it is one only mesh with matIDs and multiSub…

    So if someone has an idea, that would help.
    Regards

    Can you share a simple example file with your material? it’s can be attached to a simple shpere or only with the bulb in the scene.

    Seems like it’sa bug because of emittion settings, we’ll find out how to fix this in future, but for now you can fix it by using emittion intencity parameter instead of emition color to turn of a bulb lighting and always set emittion intencity to 0 before change the trancperency.

    thing is i will need both emission and transparency / opacity…

    Is there anyway to change material inside a multi/sub mtl within verge3D using puzzles ?

    Hi,
    We’ve found a bug with processing emission for glTF-compatible materials. The fix will be included in the upcoming Verge3D release.

    Hello again,
    Do you know when this will be fixed and released ? My current project needs it ;-)

    Best regards.

    Hello again,

    Sorry but the bugfix did not helped me, as i tried hundred of shaders and only physical gives me the desired render…
    Problem is still that transparency is not available in puzzles… Even with a controller in parameter.
    See screenshot, please.

    Solution could be to assign another material, but this one is part of multi/sub material, as the mesh contains several materials.
    As i’m cloning it, it is best to keep it as one mesh with multi/sub mtl.

    Maybe it is possible to assign a new material only for specific ID within multiMap ?

    Ok, i think i could manage it, using the (new ?) “multi-material index” to change only the transparent mtl.
