    Hi
    In terms of alpha transparency, I conducted some tests and found that it is normal when two models with transparency have the same front. When one model faces forward and the other model faces backward, the part with alpha on both models will disappear (as shown in the figure).

    Can you share the example file? We can’t reproduce the behaviour.

    Hello
    I tested the standard material transparency earlier (which is important because it supports double-sided mapping, has fewer material nodes, and requires less computation).

    Today, I tested the transparency of physical materials again and found that when models with transparency are crossed together, there will be confusion, and some opaque areas will also become transparent.

    Moreover, whether it is the transparency of standard materials or physical materials, it does not support glow (glow does not work when HDR rendering is activated in the export settings).

    The following is the attachment.

    After multiple attempts, the sample file cannot be uploaded (it only has 2mb)

    Sorry, can’t download anything from this file sharing service, because I do not understand where to click. You can zip your project and upload it to Verge3D network and share the link here.

    Yes, it’s known behaviour. It’s a problem of sorting transparent faces. May be some day we will solve it but now you can solve it by two way on your choise:
    1. Separate all faces of Box002 object so each face will be separate object with pivot in it’s center
    2. Change Blend Type of Material #0 to Coverage.
