[Web] Terrain3D Fails to Render the Ground Shader in a Browser on iPhones

[FeralBytes]

Terrain3D version

v1.0.0-dev

System information

Godot 4.4.beta3 Compatibility WebGL, both Safarri & Chrome tested on iPhone 15 iOS 18.3.1 & iPhone 13 iOS 17.5.1

Is the issue reproducable in the demo?

Yes

Issue description

The terrain does not render the mesh material. Collisions are working though.
These are screen shots from an iPhone 15:

The Terrain should look like this:

The above image was captured on a Linux Mint computer running Firefox.
The image below is from my Samsung S21 Android device running Firefox:

The S21 is also able to run the game in Chrome too with the same nice looking results.

The image below is from a iPhone 13 running the demo:

The demo is also missing the terrain material, though physics is working.

Logs

I do not own these devices personally. So unfortunately I can not provide logs. As such I do not expect you to take any action on it. If I am able to acquire logs in the future then I will post back when I have more details. Thank you again for your help and your awesome terrain.

Neither safari nor chrome on the iphones rendered? Which browser versions? The browser is doing the rendering, so if it's old, it won't support Webgl.

We can't do anything to fix browser support for webgl. That's between OS, GPU drivers, browsers, and godot.

We can provide a webgl compatible shader, which we have done.

@TokisanGames I will get the browser versions from the 2 devices. Per the pictures the devices were rendering some of the games in WebGL, they just were not rendering the terrain. But I also agree this could just be an area in which Apple devices are lacking as they have historically done.

Edit: iPhone 15 browser details: Safari is the same as the iOS version # 18.3.1 and Google version 133.0.6943.84 which looks pretty close to Stable LTS according to Googles Blog.

A lot of systems don't implement the full opengl spec and lack features such as texture arrays. Including Godot. E.g D3D12 is not supported because Godot hasn't finished implementing TAs.

IOS and macos have poor support for 3D.

Latest chrome supports everything on desktop which suggests the lack is in the OS, driver, or Godot.
