Invisible 3D models

This speaker, that supposed to show text, is just… invizible. It is here, is is working, but it just does not rendering for some reason. I thow a bunch of this speakers along the tutor yesterday, and when I launched project today, the speakers is gone invisible. I haven’t changed anything related to the rendering of the scene or layers or something.
The speaker is global object, and it is working fine at another scene. Also turning off “Emmit ambient light” setting is make it appear again, but it just look worse than should.

The speaker in editor

The same place ingame

Did you try putting it on different layer or checking if it works on different scene same way?

No, the speaker is on the right layer, and is work as it should on the other scene’s

Did you try to add speaker again like make new model object in gdevelop call it Speaker2 and check if same thing happens

Can you let us know the exact GDevelop version you’re using (shown in the About GDevelop dialog). Thanks!

Unfortunally, I added the same model as other object, and this is not working
It seems like something wron with the material of original asset, because other models, that I made by myself is working totaly fine. Even if I put fancy shader over them. Well, now I have to do all work by myself, what a good moral of the story! Thank you, anyway.
