Hi all:
I wish to make a render of a tree.
I am papped uv the leaves. I put the following code:
texture {
pigment { image_map{ png "palmera.png" interpolate 2}}
normal { bump_map{ png "palmera_bump.png" bump_size 0.8}}
finish { diffuse 0.8 specular 0.5 ambient 0.100000 roughness 1/50 }
}
what it takes to put for the plane transparent?
Thanks.
Tony

That would be the same technique that Edouard demonstrated before except using a
palmera_mask where the area outside the leaf is black and inside the leaf is
white. Transparent texture for the black areas and leaf texture for the white
areas, something like:
#declare T_Palmera = texture {
pigment { image_map{ png "palmera.png" interpolate 2}}
normal { bump_map{ png "palmera_bump.png" bump_size 0.8}}
finish { diffuse 0.8 specular 0.5 ambient 0.100000 roughness 1/50 }
}
texture {
image_pattern { png "palmera_mask.png" }
texture_map {
[0 pigment { rgbt 1 } finish { ambient 0 diffuse 0 } ]
[1 T_Palmera ]
}
}

Wouldn't POV-Ray simply use the alpha channel of the png file as well?

Only if the png /has/ an alpha channel ;-)
But if it does, then yes.
