Textures on sideways, and no dynamic textures?


Recommended Posts

We've just tried moving a site from 2.2 to 3.0. We're left with a couple of breakages that have me stumped, and that I cannot see mentioned in the change log. (UPDATE: managed to fix both while writing this message!!)

1. A sphere with a earth.jpg texture applied. The texture now looks like it is sideways... ah, just fixed this! I think this might have been a bug prior to 2.3, and I was working around it? I.e. it seems my earth.jpg was rotated sideways! Turning it to have North at the top half-fixed it. The other half of the fix was to add

sphere.rotation.x = Math.PI;

2. See https://www.babylonjs-playground.com/#2S68ZN

which is showing drawing text on to a dynamic texture, then using it as a particle.

Compare with https://www.babylonjs-playground.com/indexstable#2S68ZN

I.e. it looks like 3.1 is going to fix whatever the problem is? (I still thought I'd report it, in case this was an accidental fix!)

I've got one machine where https://www.babylonjs-playground.com/#2S68ZN is not working. Nothing in the log; when I did a console.log(tc.textSize) I get 43, which sounds suspiciously low.  I thought it might be something about fonts, but when I test on the old Babylon 2.2 version it is working (my real site, not the above playground, obviously).

So, I have:

 2.2: works everywhere

 3.0: works nowhere

 3.1-latest: works on fast Mint 18 with a GPU (firefox and chrome), works on a feeble-CPU Windows 7 no GPU (chrome), doesn't work on fairly fast Mint 17 with no GPU (two different users, both firefox and chrome tested)

If anyone else has it not working, perhaps you could post? "Working" is you see the word "testing..." keep spewing out and going down through the ground. "Not working" is you just see the plane and nothing happens.  Thanks!
