Depending on the previous version of blender you originally created your scene in the BSDF shader node may be incompatible. You will find the 4.2 BSDF is completely different. You will probably need to update your shader nodes on your scene by replacing the old BSDF nodes with the new version. I suggest looking at the other nodes and change logs to see if you need to update anything else.

And this…odds are there is more optimization to do and it might fix it…or there may be even more to do.

well….its not possible for me to answer that without seeing the code of both apps and comparing them. What you may want to do is not host the verge3d portion of you application on soft8soft servers and host it like a regular webpage on your website so that you don’t have this issue….if this is the issue. Without seeing your project I can’t actually state with any real certainty that this is the issue…just my best guess based on the way iOS is failing.

My guess is you have Ambient Occlusion turned on? If so try turning it off and see if the artifacts are still there.

Good luck…. the Verge3D puzzle is dialog HTML that has the modal option.

Ok…so that we are talking about the same things… “scene” can mean different things to different people.

Scene in the world of 3D has multiple meanings. In 3D applications you can multiple scenes in within a file. These can be anything from product objects to entire forests. In Verge3D it has two meaningss. The first is based on the Scene Puzzle. A naming convention I wish didn’t exist…It should just be called “Load GLTF” and a more generic name as the overall content within the canvas window.

The default V3D application will load a scene containing the V3D cube a light and a camera. No puzzles. To dynamically replace the cube with something else ( another scene – meaning replace the existing geo with some new geo). We have to use the Scene Puzzle and define the GLTF that we want loaded. But the GLTF does not have any puzzles associated with it.

However if your first scene contains a HTML button named “Button” when you load in the new geo/GLTF the HTML button will remain with the same functionality you originally provided. Loading in the new GLTF does not change your puzzles. So the Button will continue to work. However if you had an object called Cube at the start and you had a set of puzzles that are specific to that Cube or reference that cube those puzzles wont work once the cube is no longer loaded.

To get around this problem. You may find it easier to load all your objects into your base scene inittially, create all your puzzles, then remove the objects you want to load in.
The puzzles objects will turn red indicating they are not loaded but they will work once the new GLTF is loaded.

The Load and Unload sample project is a bit basic and doesn’t quite describe the issues you are having but if all your puzzles are in the first project and you are just loading in and unloading GLTFs you are going to be good.
