strange effect on sprites

[Dad72]

I do not know why I have a hole in my clouds. I use the same texture as that found in Babylon, here
 
Test This way less here, but you can see some artifact on each sprite
 
On my project it is still more obvious :
 

 
An idea of who could produce it this?

Sprites are using alphatesting and not alphablending

 

you should use this kind of technique:

I had to try this type of technique but I do not manage a good result because depending on where the camera looked at the result was pretty bad, so I use the sprite possible to always have the cloud that looks at the camera.

 

How can I use alphatesting the sprite? I do not see where I use alphablending.

[GameMonetize]

Basically sprites are using alphatesting and there is no way to use alphablending instead

 

you can use meshes with billboard I think

[Dad72]

The advantage of sprites is that still face the camera without additional code. but with the last correction you made, I'm just little spots that I do not yet understand. It's probably because of the texture with opatity and what you are talking alphatesting and blending.

 

Thanks
