Opacity map does not work properly

[krs]

Hello everyone.
So I've got this problem with opacity.I've tried to look for the solution here but without success.
Leaf material on this tree is a converted vray mat.Opacity map is a bw jpg.In the material editor everything seems to be ok but when rendering, opacity map just doesnt do the job.

It must to work good.
Can you show your material?

[krs]

Sure.

[3dgraphics]

can you show the settings in your opacity map field?

[krs]

Here it is.I think that I might have not ticked a proper option somewhere.

My guess is that your uv map doesn't fit in 0-1 space and since you unticked Tile checkboxes in bitmap's coordinates rollout - you got what you got.

Possible solution: fit uv map to 0-1 space and use cropping in bitmap's parameter rollout instead.

romullus got it! If you look closely, your leafs are transparent in the middle "map-sized rectangle", but not outside. Just set the opacity color to black (the one above the absorption parameters) and it should be fine. It's taking this color for everything not covered by your bitmap.

Great success:)
That was exactly it.I don't know if I fully understood romullus, but changing the opacity color worked just right.Thank You very much guys!
