This looks like it might be a driver problem, but it’s difficult to guess more as I’m not familiar with this device. If it’s a browser issue, in theory there should be an error message; can you connect your Chrome DevTools to your tablet’s browser and see if it says anything?
I think the best you can do is just trying what is working and what is not working on the targeted device. If you are targeting masses, well… Generally PBR is working on mobile devices. I’m targeting mobile devices with my current project and except the low ends it is working. I have to scale down the textures though. However this one is not working on my phone and it is just a cube texture applied on a sphere. This made me curious…
I’m going to play with this a little bit
Cool! In this case, there must be some WebGL feature your GPU doesn’t like that Babylon is using but Three is not. @Evgeni_Popov, any ideas what might be causing this?
Great, so let s try to narrow the issue, I am sorry in advance of the numerous try and fail we will have, but I need to narrow down which feature is not working
