Woot, just found a bunch of them in this site and I will try them :D Title: Re: Bump/image maps Post by: DarkBeam on December 27, 2011, 10:38:23 AM Result; Houston we have a bump! Landing now!!! :o
Used a RPow3 and as pretransform a _MapTranslate :dink: Title: Re: Bump/image maps Post by: Sockratease on December 27, 2011, 11:17:32 AM a _MapTranslate :dink: MapTranslate?? How did I miss that one?? Well... Time to go see what Lissa's Pictures do with that feature!! Title: Re: Bump/image maps Post by: DarkBeam on December 27, 2011, 11:42:03 AM a _MapTranslate :dink: MapTranslate?? How did I miss that one?? Well... Time to go see what Lissa's Pictures do with that feature!! That is the problem! In fact a bump map is different from a normal image; every pixel's lightness must express the height of the bump map in that pixel, plus you need to provide the info in spherical coords, and it seems that it's impossible to match bump and color map for now :sad1: edit; try also those textures but too bad they are in rectangular coords. And the old problem bump/color persists http://www.samuraisquirrel.com/Textures/Textures.html Earth's bump map: http://en.pudn.com/downloads83/sourcecode/graph/detail319133_en.html Title: Re: Bump/image maps Post by: DarkBeam on December 27, 2011, 12:02:12 PM An example of female head mapping http://grico316.com/pages/Bionic_Chick.html
The result is so crappy :o Title: Re: Bump/image maps Post by: Sockratease on December 27, 2011, 12:47:07 PM An example of female head mapping http://grico316.com/pages/Bionic_Chick.html The result is so crappy :o From the screenshot, it seems you used a texture map from a 3D Program, I have been playing with straight photos (albeit some play with using the Threshold, Grayscale, and sketch filters in Pixelmator to enhance the bump quality). I'll have some results soon - Lissa has been known to get upset if I post ... unflattering images. And when SHE gets upset... :hurt: :fiery: :hurt: :over: :hurt: :fiery: :hurt: Title: Re: Bump/image maps Post by: Sockratease on December 27, 2011, 12:57:38 PM Just followed the link you provided.
Have you tried the provided bump map of the same face? It should give better results than the diffuse map it seems you used (bump map is further down on the same page). Title: Re: Bump/image maps Post by: DarkBeam on December 27, 2011, 04:20:14 PM Yes of course, but the fact is that the bump map is studied for modelling a mesh already very close to a human face, not a sphere, that's why it does not work, anyway we are asking too much from that poor software that works so good! ;)
Another try with that bump map; eeek!!! Title: Re: Bump/image maps Post by: Sockratease on December 27, 2011, 04:55:31 PM eeek!!! Indeed!
Now, to find a way to animate that sort of thing with the translation parameters... :devil: Title: Re: Bump/image maps Post by: Aexion on December 27, 2011, 05:13:53 PM Try skulls ;D
