Here’s a sample of strawberries I created in Blender; using the same textures from my previous post, but created new polygons.
From the latest release of Blender (2.64a), I haven’t tried an alpha mapped texture in Blender– if the renderer to use is Cycles. Adding a texture, like a strawberry leaf (from my previous experiment with Maya), contains an alpha channel (certain areas that are transparent). It’s easy to implement in Maya (tested on mental ray renderer), after the uv mapping,– add texture, and the bump map for additional effect, then render. But in Blender’s cycles, it’s a different approach. It took me hours to figure out how to render the transparent (alpha) effect in cycles because of the lack of available documentation–all of my renders are just patches of black geometry from the strawberry leaf.

Update: Here’s the setting I found out on how to use the transparency setting (alpha) on Blender using the Node editor (Compositing). Just select the polygons (you can see in the picture) to see the materials, and attach the alpha to the fac of the mix shader.
Thank your explanation of cycles alpha mapping!
thanks …
ive been days trying to figure this out thanks my friend had something similar but had the image node connected to the transparent node pisser lol
muito bom… very good! very easy!! thanks a lot!!
nice ! thanks!
I looked at so many examples of this. no one does it “the right way”. this is by far the best way to do it! saved me a lot of hassle, thanks!
You’re welcome
Hey, I’m trying to get my png image with transparency to do the exact same thing as what you have here. I set up my node editor the same, and my PNG is still showing black, and it’s making the main part of the image transparent! Any ideas?
Strange. I tested the same blend file on the newer build of Blender (2.71 RC2) and the transparency still working.
It does not work. I have white places and my shadow is wrong.
Odd…unless you share to me your blend file and textures to see.
Cheers man, just what I needed!
