How to place a PNG image as a label on a bottle...
-
What is the proper method of placing a PNG image on a model as a texture and preserve the transparency when it is rendered. I use V-Ray and am wondering if it is a V-Ray setting or a Sketchup issue....?
Thanks,
Jeff

V-Ray doesn't read the transparency information in PNG images - or any formats.
You must supply the transparency in a separate grayscale image and load that into the transparency slot in the diffuse channel. -
Ok, so if I were wanting to make a bottle that is red and I wanted to apply a label. Listed is what I would have to do?:
- make bottle and paint red
- import texture and apply the label image.
- in V-Ray material window, select diffuse tab, click transparent and make white.
- in diffuse tab, click "m" on transparent select bitmap on common drop down.
- click "m" in bitmap and select a grey scale of the label graphic.
And that's it? I must be missing something. When I do it like this, the bottle turns transparent red.
