Hi, this is just a simple case of what I’m trying to achieve with the AR mode

I have a green cube that export perfectly into AR mode

but if i try to apply a new material to it (like red) and I export it again, it will keep the base material “green” and not export with the new red material.

try it : https://v3d.net/133h

if someone has ever faced this issue, i’ll be happy to hear it

more info :

it does the same if i set the export usdz to the “cube” model and not to the “scene”.

According to the puzzles above your cube is exported to USDZ only once, right after the app has been loaded. To get what you want the cube should be exported on demand, after its material was changed. Puzzles will be a little more complex…

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Thanks for your reply.
I tried it and nothing happen.
I absolutly need it to work because if it doesn’t work i’ll have to export manually 634 usdz models to the media folder and create a script for each of them.
thanks

I’m having another issue with the AR mode.

If I use “puzzle-1” (picture example below). It does export the new material applied to it (which is great).
But the problem is when I click on the AR button (from my phone) they ask me if I want to download the usdz model, once downloaded, I have to go through the download list and open it from there.

Compare to “puzzle-2” (picture example below). That if I click on the AR button (from my phone) they ask me if I want to open the 3D file (without having to search it from the download list) which is what I want to achieve. Only problem it doesn’t export the new material applied to it.

I’m not sure what I can do to fix it.

Thanks for your help!
