Josh1587140445 Posted November 7, 2002 Share Posted November 7, 2002 I have a question when it comes to overlaying wireframes over other image in photoshop. Check out this post for an idea of what i am trying to do. http://www.cgarchitect.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=5;t=000123 I am currently using viz4 as the rendering package. But when I render a wireframe model I get a black background. So how are you suppose to get a transparent background so you can overlay the wireframe without having to fade or erase?

plastic Posted November 7, 2002 Share Posted November 7, 2002 save as tif, for example. then there also is an alpha channel ( = background) included in the file. laod it with photoshop, go to load selection and choose alpha... Link to comment Share on other sites More sharing options...
Administrators Jeff Mottle Posted November 7, 2002 Administrators Share Posted November 7, 2002 Hey Josh, What I normally do is render the wireframe on a black background then screen it overtop of the rendering in Photoshop. Link to comment Share on other sites More sharing options...
Josh1587140445 Posted November 7, 2002 Author Share Posted November 7, 2002 Screen? What do you mean by screening it? Is it the same thing as fading it? I would look, but I have paintshop pro here at work. So I would have to wait to check photoshop when I get home. Link to comment Share on other sites More sharing options...
nisus Posted November 7, 2002 Share Posted November 7, 2002 Screen is just another blending mode. When you overlap to layers and set the topmost to screen-*BM, the 'whites' of the top layer are added to the ones underneath. 'Screen' is the opposite BM of 'multiply', where the 'blacks' are added together. rgds nisus *BM: blending mode Link to comment Share on other sites More sharing options...
STRAT Posted November 8, 2002 Share Posted November 8, 2002 another effective method is learning about feather blending - Link to comment Share on other sites More sharing options...
Josh1587140445 Posted November 8, 2002 Author Share Posted November 8, 2002 that looks awesome. Well I just upgraded to Photoshop 7 at home. And it is coming with a DVD filled with tutorials from the photoshop masters. So hopefully I will learn some stuff from it. Link to comment Share on other sites More sharing options...
