    Hi,

    I have duplicated the new version of DEMO AR but I can’t figure out how to light my scene (The AR demo uses Emission to light the Farmer mesh but I would hope their is an other way).
    I want to use the light of my HDRI and it seems to be no problem on my viewport. But when I click on sneak peak it becomes pitch black.

    If I had a light source it works fine though but it would require too many of them =.

    It might be very obvious but I can’t find where :unsure:

    Thanks !

    In your browser press F12 and see the log.

    Hi kdv,

    It seems to be an issue with the “Fragment shader” that doesn’t compile.
    I haven’t noticed any other issue besides this one.

    Don’t know if it worth mentioning but the HDRI I am using is the “environment verge3d.hdr”.
    Also up to date with V3D Version: 4.6.0 and blender 4.1.

    As usual, the stability and compatibility of the latest versions is questionable :unsure:

    Try Blender 3.6.x or Verge3D 4.5.1. Or both together.

    I have tried all the combinations including Blender version 3.5.1. Still, all the meshes remain pitch black if there is only an HDRI (As I said I don’t want any source light on top of the HDRI which should be enough).

    What I don’t understand is that I don’t have any problem if I would start a new blender file from scratch (or duplicate from another app such as the scooter for instance). The HDRI lights my scene as excepted. Only AR Demo doesn’t work.

    The only reason I don’t start a new blender file and then replicate the puzzle from the AR Demo into my app is that there is a bug when I use it on android (Verge3D has acknowledge the issue and is currently working on a patch).

    In the mean time I am hoping to find a solution regarding this “Fragment shader” issue.

    Did you download the latest AR Demo from the Asset store and just open .blend file with no changes? I did the same and see no problems with the HDRi lighting at all :unsure: Blender 3.6.9

    Check this option in Blender. It shouldn’t be None (fastest).

    You are right !!

    It was on None (fastest) by default. It works now :)

    Thank you for your help again :good:

    It’s an old bug with IBL since 4.3, when they in S8S removed cubemaps and didn’t clear the code properly. None (fastest) throws this shader error.

    How can we reproduce this behavior? :scratch:

    The way he did. Take your AR demo .blend file, add HDRi map to the world material but do not change the IBL mode. Leave it None (fastest).

    I can’t reproduce this bug for now ))) It was a long time ago when I encountered this issue and I don’t remember details.
