Created attachment 443983 [details] ios15, missing texture (middle of the field is black) Referencing the original issue from here: https://discourse.threejs.org/t/textures-in-gltf-sometimes-display-black-but-only-on-ios/30520/2 Repo app: https://hc1vv.csb.app/ Code: https://codesandbox.io/s/three-js-gltf-stadium-hc1vv?file=/index.js iOS14: Works as expected, all three textures are loaded iOS15.0.2 / iOS15.2: [regression] Behavior 1) Missing textures (ie one or more of the textures is black). Behavior 2) Page reloads or crashes (potential memory issue) Behavior 3) It should also be noted that it takes a significantly longer time to load the textures on iOS15 vs iOS14 Tested with these combinations with the same effect: [GPU Process: WebGL, GPU Process: Canvas Rendering, WebGL via Metal, WebGL 2.0] Another example of this issue: https://discourse.threejs.org/t/missing-textures-on-safari-ios15/30245
