--- Comment #3 from Michael Herzog <michael.herzog at human-interactive.org> ---
This issue was also reported at the three.js forum (https://discourse.threejs.org/t/texture-rgb-values-are-zero-when-alpha-is-zero-on-ios/6840). We've added a fiddle that should work as an additional test case. Normally, the entire plane should be red. On iOS Safari and Chrome, the bottom left part of the plane is black. https://jsfiddle.net/vyzc2sgj/1/
