Unwanted border around texture with alpha

[Janx]

Hi,

I want to use textures with contain areas which zero alpha. However I see unwanted borders around them. Here is a playground to clarify my problem: http://www.babylonjs-playground.com/#AN5WBF#3

Am I doing something wrong? How can I get rid of the border?

Edit: Here is the same problem, with a different texture: http://www.babylonjs-playground.com/#AN5WBF#4

Many thanks,
Cheers,

Hi @Janx

Your issue seemed to mainly be bad lightning,

Here's a fixed & simplified version; http://www.babylonjs-playground.com/#AN5WBF#5

Hi guys!  Also, you may wish to add the clamps... to the opacityTexture and emissiveTexture channels, too.

Lines 50-54. 

There is some kind of border dispute between the Babylonians and the Epsilonians.  One of those countries talked of building a wall on the border, but it was deemed "inini".  (infeasible'n'implausible'n'impractical)    (okay, okay, I don't have the BEST comedy writers, but my guys work cheap).

Hi guys,

thanks for the quick help. The gradient looks good, but when I try it with the star, I still get these borders: http://www.babylonjs-playground.com/#AN5WBF#8 

Basically what I want is a texture with alpha one a plane which is not affected by lighting. Am I better off writing a custom shader?

Many thanks,
