Label masking and tiling

Hi all

As a newbie still learning the basics of octane i have come to standstill again with this little one.

Im trying to add a label to my object/bottle and am following what I believe is the correct way to do it but no matter what i do I keep getting the label trying to tile itself outside the one I want to keep and also I cant seem to remove the duplicates that sit top and bottom. Ive looked at using the black colour and white colour modes along with the alpha but im getting no joy and the whole label actually disappears. Hopefully someone can point this out to me.

Im attaching my file and screen shots.

Thanks in advance

What is it you want to achieve?

Personally I would be creating a separate label model from a flat plane, applying materials as flat projection, the create UV co-ordinates, then bend the label to fit the bottle.

Hi mitchino. Thanks for your reply.

Im just trying to apply a simple label to my bottle. Ive done a split from the main bottle and used that for applying my label. Ive seen this done by others on youtube so thought it be easy enough. The application of the actual label is easy enough but then i get this tiling problem and the inability to alpha out the shape. I hear you regarding using a spline for the label and then deforming it around the bottle and thats a good idea too but not all labels are always that simple and the use of alpha masks is essential but if this problem persists then I must be missing something? Or not doing something quite right?

OK, not sure why it's not working for you, I've made a simple scene for you, there is a simple Octane material with an Octane Image Texture in the opacity channel. This is an RGB .psd file with 2 layers. Applied with cylindrical mapping to the label mesh and the fit to object command.

Just works for me, maybe you can find something in my scene to help you.
