I got an issue regarding CORS policy.

I’m loading image urls at runtime. This works without any issue when I add the images as simple html (img tag or as background-image).

But when I try to load the exact same images via url as an texure in verge, I’m getting the “blocked by CORS policy” error. I dont quite get why this happends only for the texture loading via verge. Where is the difference?

This is the way I’m loading the textures:
var texture = new v3d.TextureLoader().load('http://example.com/image01.png');

When you load images from a different domain using img tag, its ok, since no JS involved. However, when you load images with Puzzles (or JavaScript), this is entirely different story.

Okay, I see thank for the clarification. So the only way to solve this, is to either host on the same domain or add “Access-Control-Allow-Origin: *” to the server side, correct?

Or do you know of another possible workaround?

Can you explain “However, when you load images with Puzzles (or JavaScript), this is entirely different story.” We made Verge3D as a vuejs component, it works well on same domain but when we tried to load img or gltf from another subdomain for example UI with verge3d is on live.domain.com and gltf and other files are on storage.domain.com we get CORS.
We already setup “Access-Control-Allow-Origin: * on serverside.
But somehow v3d is not sending headers to server.
Can you help with that?
