It seems to me that the problem is related to the use of floating-point textures, but my knowledge ends there. \r\n\r\nThe problem is that the things the shaders do in these examples (i.e. forming the waves in the water example) don't seem to take, and it will repeatedly spit out the two errors above.\r\n\r\nI could reproduce this on an iPad (9.3.3), iPhone 6 (9.0.2), and iPhone 6s (9.3.4), using both Chrome and Safari. I do not know if this affects Android, but it seems likely.\r\n\r\n##### Three.js version\r\n\r\n- [x] Dev\r\n- [x] r80\r\n- [ ] ...\r\n\r\n##### Browser\r\n\r\n- [x] All of them\r\n- [ ] Chrome\r\n- [ ] Firefox\r\n- [ ] Internet Explorer\r\n\r\n##### OS\r\n\r\n- [ ] All of them\r\n- [ ] Windows\r\n- [ ] Linux\r\n- [ ] Android\r\n- [x] IOS\r\n\r\n##### Hardware Requirements (graphics card, VR Device, ...)\r\nAny device with iOS 8.0+, most likely\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/mrdoob/three.js/issues/comments/245699793","html_url":"https://github.com/mrdoob/three.js/issues/9628#issuecomment-245699793","issue_url":"https://api.github.com/repos/mrdoob/three.js/issues/9628","id":245699793,"user":{"login":"mrdoob","id":97088,"avatar_url":"https://avatars.githubusercontent.com/u/97088?v=3","gravatar_id":"","url":"https://api.github.com/users/mrdoob","html_url":"https://github.com/mrdoob","followers_url":"https://api.github.com/users/mrdoob/followers","following_url":"https://api.github.com/users/mrdoob/following{/other_user}","gists_url":"https://api.github.com/users/mrdoob/gists{/gist_id}","starred_url":"https://api.github.com/users/mrdoob/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mrdoob/subscriptions","organizations_url":"https://api.github.com/users/mrdoob/orgs","repos_url":"https://api.github.com/users/mrdoob/repos","events_url":"https://api.github.com/users/mrdoob/events{/privacy}","received_events_url":"https://api.github.com/users/mrdoob/received_events","type":"User","site_admin":false},"created_at":"2016-09-08T18:47:27Z","updated_at":"2016-09-08T18:47:27Z","body":"Works fine! 👌"}}
