Latest asset to be accepted by Unity is the test tubes + wooden stand.
Now, I like Sketchfab. Once upon a time, in the early days of selling models on the Unity Asset Store, I tinkered with Sketchfab, but it rarely displayed my models correctly; things flickered and there were strange visual distortions. But, Unity displayed them fine; so did Blender, and lots of other 3D packages I used. So … I decided there was something wrong with Sketchfab’s engine, and called it quits (it’s been nearly a year since I last visited the site); if it couldn’t display a simple model correctly, then what was the point? The research I did into the issue pointed me at some strange dark magic within Sketchfab’s codebase, and the devs didn’t seem to know what had happened, though they gave suggestions for anyone using Maya / Max. I mostly use Blender to model, and what they suggested I couldn’t translate across.
Woke up a few days ago, and thought: what if Sketchfab cannot correctly display N-gons? In my early modelling days, I thought N-gons were a silver bullet; suddenly, you could model anything in anyway you saw fit; it was like magic, and I used this magic a lot. But, no: N-gons are nothing but a tool, and should never be left in a production model. Most engines will triangulate them (which is why they displayed fine in Unity / plus, I’m mostly a hard-surface modeller, so the auto-triangulation would never be apparent, as animations rarely deform the model’s surface).
I tested this by importing a chunk of my newer, N-gon free models into Sketchfab, and despite their significant increase in complexity to my earlier stuff, every single model looked moreorless identical to what I saw in Unity. Problem solved: Sketchfab doesn’t auto-triangulate models, and cannot correctly display N-gons (or, something along those lines).
Would have been nice if the Sketchfab engine pointed this out — dude, N-gons aren’t supported. I wouldn’t have understood what it was on about, but that would have prompted research into the matter.
So, to sum up: Sketchfab is pretty damned awesome (now I understand its limitations).
