How to make my own psd textures for effects ?

HI, community

there is some interesting effcts shown in the example project from here
http://unity3d.com/support/old-resources/unite-presentations/forest-talks-particles

it seems that the effect is achieved by using such some psd textures like this :






and I try to make my own psd:





than test it , But I got strange result:


the left is the original effect, the right is using my psd texture.




Am I miss something ?

Thanks.

 

Forgot the alpha?

 

There was a tutorial on Yoggy's blog describing in detail how he went about creating his particle textures in photoshop. It might be worth it for you to hunt it down.

 

I will check it later

 

are 'forestjohnson' and 'Yoggy' the same person ?

 

Yes, I forgot to add alpha channel to the layer. it works after adding alpha channel.

but the Effect looks ugly, maybe I should say, my drawing skill is awful
