cycles transparency not 100% transparent I'm using cycles to render transparency around some leaves, but the actual transparency has a slight grey tint. I read some other place on google to increase the Transparency under Light Paths in the Render Panel, but it doesn't work for me.

Anyone has another suggestion?
Raise TRANSMISSION and transparency samples:


Also don´t forget to check the ALPHA on Photoshop or GIMP, by placing a full black fill on your image as a lower layer. Delete (clean, CLAMP) your white alpha as white as it can get. Then, reload your image in Blender. This should cover it.
