How to change the world material？

Hi,

You cannot replace the world material, however, you can modify it using set value and set rgb puzzles. See the Scooter demo where the light environment is replaced by the dark one.

A simplified approach would be to have two world images in your application directory.
When you export a scene your world texture is put at the root of your application. You could copy another environmental HDR there or whatever you want to use.

Then use a “when clicked “puzzle and inside it use a “replace texture” puzzle. You then have access to the Verge3D_Environment_World and you can assign your new texture to it. You of course could trigger this change in any manner you want.
