chadsmith Posted April 17, 2003 Share Posted April 17, 2003 Ultimately I am trying to make frosted glass effectively. I can add a little self illum. but the objects seen through the glass are still sharp and they should be blurry. Same for the reflections. I wanted to know what you guys do for frosted glass so I can stop my abuse of ps. Link to comment Share on other sites More sharing options...
kid Posted April 17, 2003 Share Posted April 17, 2003 I don't know what version of Viz you're using or if Viz supports blurred refraction at all, but if it does use that. If it doesn't then you can simulate it by doing what happens in real life, ie add surface texture to your glass. Add a noise bump map to your material, scale it very, very small and this should make things behind the glass appear blurry. Link to comment Share on other sites More sharing options...
ZepSOFD Posted April 17, 2003 Share Posted April 17, 2003 If you are using Viz4 have you tried using the translucent shader in combination with what Kid posted? tom Link to comment Share on other sites More sharing options...
chadsmith Posted April 18, 2003 Author Share Posted April 18, 2003 The bump on the face of the glass only made the reflection disperse but not smoothly. You would think that making the noise/bump smaller in size would help but that only brings the reflection dispersion tighter in and eventually makes it look sharp again. I have tried the translucent shader but had no success either. And none of these solutions affect the material seen through the glass they only affect the reflection off of the glass. Still looking for guidance. Link to comment Share on other sites More sharing options...
proces2 Posted April 23, 2003 Share Posted April 23, 2003 from my knowledge, it is not possible in VIZ to make objects behind glass be blurred. the only trick i have found is to blur the glass in photoshop. isolate the glass (and what is seen through the glass) onto its own layer and apply the blur filter. i had to then clip the edge of each pane of glass so that it didn't blur into the frame/mullion. http://www.proces2.com/chevrontexaco/chevtex-2page4.htm (see doors on the left and right hand side). sean Link to comment Share on other sites More sharing options...
Joseph Petrino Posted April 23, 2003 Share Posted April 23, 2003 Try this: 1 In the glass material refraction slot, place a raytrace material. 2 in the Raytracer Options enable antialiasing (global) 3 in the antialias rollout, click override and set defocus to 10 (very blurry) 4 watch render times go through roof! If you play with the settings you might get what you want. Link to comment Share on other sites More sharing options...
