Grey screen with nme mac target
SInce I closed the nme build error issue, here's a new issue just for the grey screen. Is the nme test example running something different from the lime test example?
Can you try BasicElements example ? If BasicElements example works, its a problem in NME. It was a same problem with Lime a while ago - actually BasicScene example is visible for a fraction of a second but then goes blank. Please try BasicElements and let me know if it works.

I can't find a similarly named image in BabylonJS's assets. Trying Emscripten target now...

I get the same error as my previous comment with the acadnme/cppia target, but something flashed on the screen before going blank again.

Thank you. And you're welcome.
Anyway,

Good night and thanks for all the limes (which I think I'll use instead of nme anyway).
As strange as it is, NME throws GL Error: 1282 6x8 and goes gray screen when testing with BasicScene example but BasicElements example (and few others) works fine. I'm sure this is the same bug that existed in Lime few releases ago (about version 2.4.0 I think). It was present in Lime for 3 or 4 releases. If you had Line mesh in your scene, as long as this mesh is in frustum everything would render fine. When it goes out of frustum, you get the blank scene. Because of that I used a dirty hack - I've placed a tiny line mesh (between two points and with alpha = 0.001) in front of camera when it was created and fixed its position to always stand in front of camera so that it never leaves the frustum. It kind of worked but then something changed in Lime and this hack was not needed anymore so I removed it. I guess there's a quite a lot of code 'borrowing' between NME/Lime/Snow but while the bug was fixed in Lime it remains in NME. It looks the problem is when code is using only 'default' shader. As soon as some other shader is used (like 'line' shader from Line mesh), everything works ok.
