Sure. The message I'm getting is "TypeError: undefined is not an object (evaluating 'page.texture.setFilters')". I'd be happy to give you a link to the page if you PM me.
As for the documentation, I think that it provides good information as to what the runtime does but not a lot so far as how to set it up. Like, step 1 - download runtimes. step 2 - create directory, etc. Does that make sense? I think once I go through the process of making this work for myself I could have more feedback as far as that is concerned. Clearly it is not an issue for some people as plenty have clearly managed to get this working.
I'm wondering - if I am using the spine-widget.js approach, do I need to include any other files from the runtime on my server? I am looking at the debug console in safari for the examples on your site(at http://esotericsoftware.com/files/runtimes/spine-ts/examples/widget/) and, when I look at the resources, the spine widget expands out to show a lot of subdirectories. I've only uploaded the one file. Is this potentially where I am making my mistake?
Final update - I just spoke with Erika in the discord. She got me all fixed up (perhaps, as a puppy, I should choose a word other than "fixed"). Anyhow, I had multiple images in my atlas. That seems to be the root of the issue.
With that said, it might be worth noting that in the documentation (I didn't see it there) or having a little "troubleshooting" section for exactly situations like this.
Thanks for the assist, Nate. Whatever Erika is getting paid is not nearly enough.
