Fake Alpha Shadows

[3dreamstudios]

Or something like that. I'm not seeing how to use an alpha to CUT OUT a texture without shadows. I think we use to have a Fake Alpha Shadows or something. Not finding it anywhere I look...

The fake shadows option is there, but in the specular material. I think that what you need is to get the alpha channel using a texture node in "alpha image" node type linked to the opacity input of any material node.

Well in the past I have used DIFFUSE material with an alpha texture to make the entire polygon (except the alpha portion) be completely transparent, like a sticker of sorts...

I don't want Specular material...need diffuse to not cast shadow if it's transparent from texture...?!?

Sorry, as far as I know, this kind of effect was always done adding a copy of the texture node to extract the alpha channel linked to the diffuse node opacity input, as you can see in the attached image. If you still get a shadow effect, perhaps the material of the background object has some kind of ambient occlusion or dirt node, or something like that.
