Hash Fellow robcat2075 Posted February 13, 2010 Hash Fellow Share Posted February 13, 2010 An experiment at making dragon style spikes with displacement mapping. Semi- successful. platesH264.mov Quote Link to comment Share on other sites More sharing options...

MJL Posted February 13, 2010 Share Posted February 13, 2010 I agree with Steve392, that is way more than semi-successful. Rob, you know I've been working on getting a handle decal and bump maps. Could you possibly post the greyscale image that used for that displacement map? I don't wanna steal it, just wanna study it. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted February 13, 2010 Author Hash Fellow Share Posted February 13, 2010 If you follow one of the top spikes all the way around you'll see some oddness, which is why I say semi-successful. Could you possibly post the greyscale image that used for that displacement map? I don't wanna steal it, just wanna study it. Here you go. They generally have to be EXR to avoid banding. you can open it in A:M to see it. perpective_Render0.zip Quote Link to comment Share on other sites More sharing options...
KenH Posted February 13, 2010 Share Posted February 13, 2010 Looks good! They seem to change shape though in the renderer though. Hey, if you animate the strength of the displacement, do the spikes grow? I never though of trying that before. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted February 14, 2010 Author Hash Fellow Share Posted February 14, 2010 Hey, if you animate the strength of the displacement, do the spikes grow? Yes. This shows the percentage going from -1000 to +1000 The first half is with the original map that didn't have the base color close to middle gray. The second half is after I adjusted it in Photoshop. platesMinusToPlusCH264.mov Quote Link to comment Share on other sites More sharing options...
MJL Posted February 14, 2010 Share Posted February 14, 2010 I opened the EXR image in A:M. My computer tried to open it with an expired demo version of Photoshop that I downloaded some time back. I have Corel but it doesn't recognize the file extension. (Stupid me, what is the EXR format, anyway?) Did you create the original image in Photoshop?

TheSpleen Posted February 14, 2010 Share Posted February 14, 2010 I can see that last file working very well on a werewolf transformation as an example. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted February 14, 2010 Author Hash Fellow Share Posted February 14, 2010 I opened the EXR image in A:M. My computer tried to open it with an expired demo version of Photoshop that I downloaded some time back. There's a photoshop plugin on the OpenEXR site that might work with other software. (Stupid me, what is the EXR format, anyway?) http://en.wikipedia.org/wiki/OpenEXR Did you create the original image in Photoshop? I modeled one spike and scattered several of them on a flat surface. I shot that with an overhead camera with fog settings to make the near to far gradate from white to grey. I rendered that to the exr frame and cylinder wrapped that image on the basic shape.
