Advanced Member Shawn Driscoll Posted March 31, 2012 Advanced Member Report Share Posted March 31, 2012 This has probably been answered already somewhere. But why does the head.obj model shrink in size when importing the file with smoothing enabled? Quote Link to comment Share on other sites More sharing options...
Advanced Member johnnycore Posted March 31, 2012 Advanced Member Report Share Posted March 31, 2012 I assume you are talking about the micro vertex room with smooth object enabled? I think the smooth object button is designed for Sub-D meshes when coming from another software package. If you'd have a low res cube with 6 faces, use Sub-D on it then you would get a sphere. What you can do is export the high res mesh obviously and then paint ontop of it but this way you will loose your low res model since the painting is based on the high res model's UV's. When you export the low res cube (which has just 6 faces) and import into 3DCoat using "smooth object" you cube would become a sphere but when you press the shortcut "6" you will toggle between the high res/low res model. The low res obviously being the model where the painting is based on. I hope you understood all what I just said here.. ** edit ** I found a simple video that explains more in depth what this Sub-D does: Quote Link to comment Share on other sites More sharing options...
Advanced Member Shawn Driscoll Posted March 31, 2012 Author Advanced Member Report Share Posted March 31, 2012 I'm taking about PPP mode and importing the sample head.obj model with subdivision chosen. http://www.shonner.com/drafts/polygon_smoothing.htm shows how low-poly objects do shrink a bit. With more polys, there is almost no shrinkage. The head.obj seems to have enough polys in it that it would not shrink when smoothed just a little. Other sample OBJs don't shrink as much. My own OBJs don't shrink. So I'm wondering why the head.obj model is so small? Or is the camera being moved away from the model? I have to bring the camera in closer when this happens before I can do any painting. Quote Link to comment Share on other sites More sharing options...
Advanced Member johnnycore Posted March 31, 2012 Advanced Member Report Share Posted March 31, 2012 Hmm im not sure what kind of shrinking you mean, can you post some screenshots please? Quote Link to comment Share on other sites More sharing options...
Advanced Member Shawn Driscoll Posted March 31, 2012 Author Advanced Member Report Share Posted March 31, 2012 Before and after smoothing. Quote Link to comment Share on other sites More sharing options...
Advanced Member johnnycore Posted March 31, 2012 Advanced Member Report Share Posted March 31, 2012 Ah yes I see it now.. havent noticed this before, at first I tought you meant another kind of shrinking. This looks like a bug to me.. Quote Link to comment Share on other sites More sharing options...
Advanced Member Shawn Driscoll Posted March 31, 2012 Author Advanced Member Report Share Posted March 31, 2012 If it is a bug, it's been one since version 2.0. I think it would have been fixed by now if it was a bug. Or am I the only one that can do this trick? Quote Link to comment Share on other sites More sharing options...
Advanced Member johnnycore Posted March 31, 2012 Advanced Member Report Share Posted March 31, 2012 The trick also works on my end, just never used the head.obj so I did not notice this.. Quote Link to comment Share on other sites More sharing options...
Advanced Member Shawn Driscoll Posted April 11, 2012 Author Advanced Member Report Share Posted April 11, 2012 The bug is fixed in 3.7.10. Quote Link to comment Share on other sites More sharing options...
