Realistic Leaves, Use of Alpha in Octane Live Render
Moderators: ChrisHekman, aoktar
I am trying to get the palm leaves here to look right. I am sure I overlooked somethingI can get it right in C4d but it does not render right in Octane. Any ideas?

use Octane material, put imagetexture to opacity with alpha image or white/black images for opacity. Tou use alpha of image, you may change mode of imagetexture to alphabuzby wrote:I am trying to get the palm leaves here to look right.

Sorry I am not seeing it. I tried setting the texture to Alpha but you can see the leaves do not show up.aoktar wrote:use Octane material, put imagetexture to opacity with alpha image or white/black images for opacity.

for best result don't use images directly but load the octane "image-texture" node first, in the lower field you could specify the type like image (rgb), float (grayscale) and alpha (if the image has one)

sorry what is the path to "load the octane "image-texture" node"? I dont see it in the materials menu

think at octane nodes like c4d shaders, so if you click the arrow near the texture field, go to c4doctane/imagetexture 
here you can find all the octane nodes like turbulance and so on.

I can get this result by putting the black and white jpg in the opacity. but I am not getting the green color

Not sure why mine are not the same. My leaves are barely visible on the trees. I tried both of these
