    I don’t know why but some objects in some blender files have their normals inverted when I export the Verge3D file or use Sneak Peak. I check the normals are correct in blender but when I export they are inverted. The objects also appear transparent to light if metallic is set >0 in the BSDF shader. I have attached some images and the application folder.

    Blender 2.92.0
    Verge 3D Version: 3.6.1
    Google Chrome and Edge

    Update: I changed the title to better reflect the main problem after solving the first issue where I was inadvertently rendering the back faces.

    Hi,
    Looks like you render the Back side of your mesh. See the attached screenshot.

    Thanks, I must have clicked that when I was trying to solve the other problem and didn’t realize what I did.
    Now that that is fixed, however,

      I still see light from the environment passing through the object even though the alpha channel is set to 1.

    See the attached image and application folder again.

    Could you take a look again at this? I can’t figure out why it is doing this.

    Thanks for your help!

    Any ideas on what is wrong with my file?
    Here is an additional video to show that I am rendering the front side but when I do a Sneak Peak, the lights from the environment pass through my model.
    I won’t re-attach the application folder since nothing has changed since my last post above.
    Thank you for taking a look!

    This troubles caused by camera scale, if you set camera scale to 1 all will be ok.
