WIP help needed

as you can see on the bottle label has a problem with the opacity why does this occour the label are duplicated polygons from the bottle.
I have used the same technique for the glass but you can’t see the problem there.

material used for the label is standard max mat with no glossines or reflecions.

hi spirit1,

check the alpha-channel of your map,
set the the transparent areas to pure black.

Deneb: thanks for your reply but i must be stupid or something where do you mean in the opacity option of the material i have put a gif map black and white do i have to do something else?

could you post the map, so we can take a look at it.
thanks.

here it is

Sometimes I can fix opacity by simply checking supersampling in the materials with defaults on. See if that takes care of it.

it seems that the white isn’t ‘real’ white, but i think that
won’t explain your problem.

generally i would use 32-bit tga’s with the alpha-map included.
the boarders of your gif-picture (black/white) are quite sharp and jaggy.
create an alpha-channel in photoshop and save the map as a tga.
hope this will help.

nice evening to all
ale

i changed the material to vray and now it works.

thank’s for your help :slight_smile:

You know why it works now?

The missing transparency of your label were simply reflections.
If you use any shader containing a highlight you have to map the specular
level too to make it dissapear on totally transparent areas of the geometry.

thank’s Ron i didn’t know that, it’s good to know why as well not only to get it work but the reason why it didn’t work in the first place.
