Hi
I'm very new to the modelling game - I've got Truespace 7.6 and enjoying the learning curve!
I'm trying to simulate an image printed onto glass, whereby only the non-white elements of my image appear on the surface of the flat pane of glass.
when I apply the image as a Color to the pane of glass, the image also appears with transparency, which I understand, but its not what I want.
Any help would be much appreciated.
Thanks |

Ok.. My way (and i think the best way) could be..
For example to make the label on a bottle..
Create the bottle ;)
Select the faces of the bottle where the label must be..
Then copy those faces and separate them from the original mesh.
If the Label has a specific shape create a alpha map and attach it with a texture map..
You should move your label a bit to avoid overlaping..
Sorry for my poor explanation, im working better with Videos :)
I will try to make a Tutorial showing that..

If you are using Lightworks, you can use layered shaders. This will let different parts of the surface have different color, reflectance, bump and transmission.
V-Ray for tS and the real-time render engine don't support layered shaders at present, so you would need to go for a different approach there, probably involving geometry as Prodigy mentions.
HTH!

Tom has right.. That's another way...
But i ussual recomend work with Vray and Workspace Side.. |

Thanks Guys
I'm working mainly in Model mode and using LightWorks - I can't render in Workspace as it says I have no offline renderer.
I'll check out the layers in the help files first and go from there.
Thanks again! |

Hi Tom
Just done the layered shading by including a glass layer which looks great, and over that a layer with the Color set to my png image and the alpha mask set to my mask image.
My main image has a white border, as does my mask, so the border should disappear showing glass around it. But on the overlying image layer, I set the Bump and Reflectance shaders alpha blend to zero, then the border is not transparent and just displays the white border of the image. If I set the Bump and Reflectance shaders alpha blend to one, then the overlying image is completely semi transparent for some reason, even though my mask has the central area as black.
It doesn't seem as though it should behave like this to me, but perhaps I'm doing something wrong.
any help would be much appreciated.
Thanks. |

Hi again Tom
Just to say, I've cracked it!
I needed to set the same mask in the Bump and relectance layers as well.
Many thanks for your help with this. |

Good to hear you got it solved, and happy to help! I'd be interested to see what you're working on, if you can share an image or render, always fun to see what people are working on :)
Thanks!

you can render in workspace without an offline renderer
