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?notice the area around the leaves and the particle system plane

    $\begingroup$ you have to look at the node, it's not 100% white, maybe it's your problem? If so, push it 100% white $\endgroup$ – moonboots Feb 12 at 21:12
  • $\begingroup$ You mean the color in the transparent shader node? Yes it's 100% white $\endgroup$ – Dulcis Feb 12 at 21:25
  • $\begingroup$ are you sure? by default it is not $\endgroup$ – moonboots Feb 12 at 21:26
  • $\begingroup$ Hmm i added an image of the material node. It is totally white. $\endgroup$ – Dulcis Feb 12 at 21:27
  • $\begingroup$ maybe share one object with the problem (and pack the PNG): blend-exchange.giantcowfilms.com $\endgroup$ – moonboots Feb 12 at 21:29

Raise TRANSMISSION and transparency samples: enter image description here

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.

    $\begingroup$ This worked, thank you!! I also discovered a very slight bleed into the alpha space from some of the many texture layers in photoshop. Good idea to go through all the layers :) $\endgroup$ – Dulcis Feb 13 at 14:59
