Advanced Member L'Ancien Regime Posted May 29, 2015 Author Advanced Member Report Share Posted May 29, 2015 I'd cut the retopo mesh to pieces, scale them so their size is greater than a new reference mesh - then snap those parts to the surface and stitch them back together. However 3D-Coat's retopo room isn't the most comfortable for doing this kind of work, so I'd probably do the cutting/scaling/stitching part in some 3rd party dedicated modeller and import the modified mesh back to 3D-Coat for surface snapping and some further tweaking and relaxing (in the retopo room, not the tweak room of course). How to surface snap a pre existing mesh to a sculpture though? Quote Link to comment Share on other sites More sharing options...

Advanced Member L'Ancien Regime Posted May 31, 2015 Author Advanced Member Report Share Posted May 31, 2015 (edited) By the way ajz3d, that Snap Tool works great! Now I can correct my base sculpt on the fly and update its retopo mesh with the push of a button! This is very reassuring to have this ability since there's lots of tweaks and alterations I want to make as I discover more and more studying the body, like her ears which are still rather crude and perfunctory at this stage. Nice to know I won't have to wade in there and start mucking around with edge loop strategies just to correct that. So many great tools to discover in 3d Coat..

There's also this flag called Conform Retopo Mesh that you'll find in Pose, Transform and Move tools. If enabled, it will automatically snap the retopo mesh to your hipoly surface wherever you use those tools.

Advanced Member L'Ancien Regime Posted June 2, 2015 Author Advanced Member Report Share Posted June 2, 2015 OK now things get real...real tough. So I tried a lot of different stuff to bake out the textures of the voxel layer to the new retopo mesh. Bake with Normal Map (Per Pixel) consistently crashed the program. Bake Texture was problematic in its results to say the least. So then I tried Bake w/Per Pixel Painting w/ EXR displacement and was successful but with this result; So my question is; is this the kind of results I can expect from baking from a painted Voxel/Surface to a retopo mesh or is it just my novice level incompetence?

Advanced Member L'Ancien Regime Posted June 13, 2015 Author Advanced Member Report Share Posted June 13, 2015 (edited) I had a lot of problems mainly because during the hand retopo phase which was done in symmetry there were always a few seams left unattached at the meeting at the symmetry plane. In the end particularly in the internal seams of her inner mouth the only way I could close them all up was in Maya. Which meant I had to figure out how to bring the retopo .obj back into 3d coat then reattach it to the Surface mode painted sculpture room layer. Which I did, surprisingly enough. But all this takes huge amounts of time as you go through the tutorials and the documentation and the forum looking for answers, and then just trial and error, going through the UI trying out buttons and seeing what they do. I wake up at 7:30 and I hit the sack when I start falling asleep at the computer around 3:30 -4:00 AM . But then I was really maladroit figuring out how to bake it all out and then plug it into the renderer. Houdini Rules that's all I can say . It rules on every level. Now what I want to know is if this seam binding problem in the retopo room with symmetry is my problem or 3d Coat's problem. Am I doing something wrong here? or is there an improvement that Andrew needs to make? I sure wish that 3d Coat had the same documentation system that Houdini has so you could just hit the "?" on the Parameter box and get the full story on the tool you're using with examples you can load up to pull apart and figure out. Also this is not a final render; far from it.. It's an experiment for now. I just discovered how to do SSS in Mantra and how to plug in the texture maps. Also she needs her eyes and teeth and I need to tone back the SSS layer color. And the skin needs a very slight irregular sheen all over of sebum to remove the flatness of the color particularly in the highly illuminated areas. 2% or 4% opacity of specularity over her torso?

Advanced Member L'Ancien Regime Posted June 13, 2015 Author Advanced Member Report Share Posted June 13, 2015 I fine tuned that SSS shader I made in Houdini by switching off Single Scattering and changing the Attenuation on the Subsurface Color. It really made her skin, particularly on teh brightly illuminated areas of her torso delicate and more dimensional. Quote Link to comment Share on other sites More sharing options...

Advanced Member L'Ancien Regime Posted November 17, 2015 Author Advanced Member Report Share Posted November 17, 2015 We tend to take things for granted but it just dawned on me what a great program 3D Coat is for UV mapping. I remember even 7 or 8 years ago trying to learn UV mapping in Maya and just getting physically ill at trying to untangle all the vertices and edges on the UV map...horrible. I wonder if I'd even have stuck around in this medium if it weren't for 3D Coat's excellent UV mapping capabilities. Quote Link to comment Share on other sites More sharing options...

Advanced Member L'Ancien Regime Posted November 19, 2015 Author Advanced Member Report Share Posted November 19, 2015 This is really hit or miss. I'm not pulling consistent results. This isn't really working the way it should. New approach is required particularly in getting material for the normal map. PPP painting on the extracted retopo mesh can only go so far. Painting color and depth simultaneously, while tempting isn't the road to realism. Digman sent me this; http://www.3dscanstore.com/index.php?route=information/information&information_id=16 I have to say, particularly when it comes to SSS Cycles is really reallyl good. Live clay textures in surface mode next up. Quote Link to comment Share on other sites More sharing options...
