Hi, I’m trying to load a .glb model on iOS but it’s not working. It says OES\_texture\_float\_linear not supported. Works on desktop. Am I doing something wrong or is this simply not supported on iOS? Is this a model issue or something I can fix in how three.js is configured? Built-in Safari on iOS 14.0.1.
Example: [https://maps.appulize.com/all/](https://maps.appulize.com/all/) and click any flag.

Which version of iOS and which device? ([regarding your error](https://developer.mozilla.org/en-US/docs/Web/API/OES_texture_float_linear))

It’s hardware/browser WebGL support, the only way to fix it is to change the hardware (or not use floating point textures.)

Sorry, I have updated the question with the required information. So this means i could somehow modify the .glb file to use a different texture format? It comes straight out of Agisoft MetaShape so I know nothing about the texture format unfortunately.

Can you share the model / sample code that would be causing that error?
Tbh that’s the first time I see float point textures used. Changing [Texture.type](https://threejs.org/docs/#api/en/textures/Texture.type) and [Texture.format](https://threejs.org/docs/#api/en/textures/Texture.format) to an integer texture may fix the issue, but also cause colour changes / artifacts on the texture - but I’m guessing, maybe @Mugen87 / @Fyrestar will know more about how it works internally.

Of course, both models in the example link, but there is a direct one [http://maps.appulize.com/halfar/Hal%20Far%20Raceway-400k.glb](http://maps.appulize.com/halfar/Hal%20Far%20Raceway-400k.glb)
