Member probiner Posted October 14, 2009 Member Share Posted October 14, 2009 Well geothefaust posted an interesting video in Vimeo about the new UV features in 3D coat. http://vimeo.com/channels/3dcoat#7005596 And i pointed some stuff i thought that could be better. But that was in NewTek forum http://www.newtek.com/forums/showthread.php?p=936370#post936370 and welll if its good to have this kind of feedback, better to post it here too.

Member probiner Posted October 15, 2009 Author Member Share Posted October 15, 2009 -Symmetry in UvLayout is one feature that makes you save a lot of time. Imagine you have a character and you separate hands, ears, legs, arms, etc. You unwrap but then you need to tweak some parts so its not an automatic edit. You have to repeat that manual editing in the symmetrical parts and it probably won't be exactly the same. In UV Layout you define symmetry by choosin a middle edge in the 3D object. Later you can tweak an island "apply changes to symmetrical part" with a single click. This would be great in 3D coat for Symetrized Retopology, since that althoguh you now have Mirror Snapping, if you use Brush to edit the Mesh it will bring polygons from the other side and they will be mirrored too. This could be fixed by the above feature, or by defininf Mirror Edge Loop wich X value is always 0. -UvLayout has a relaxing calculation mode in wich you can pre-establish lots of behaviours to vertices and edges. They can go straight, be pinned, hold an hole, relx more or less, etc... So you can recalculate the unwrap with a lot of refined setups. -UvLayout Packing system is great. You can choose in how many Tiles you want to acomadate your islands, if you want them to be rotated, scaled, at packing time. You can choose the spacing between islands. And in the end it shows you the UV space coverage of the UV. This is all high end UV stuff, but... sometimes you need it, other times it's simply for time saving. But let's not forget that 3D-coat lives from UVs and what it's baked with them. Still i think the new tools can cut it. I simply point stuff where 3D-coat could improve, but it's already very competitive for its price. Also the PLG UV has some neat features that relate to what have already been said (Packing Islands options, Aligning Islands). But there is a thing with PLG that is nice, you have Relaxing using Area Weight. So you get a optimal correspondence between 3D space and UVspace. That how i got those results, that result better than 3D coat ABF++. Cheers Quote Link to comment Share on other sites More sharing options...
Andrew Shpagin Posted October 16, 2009 Share Posted October 16, 2009 I improved UV relaxing method essentially using your samples from NewTek forum. Thanks! Quote Link to comment Share on other sites More sharing options...
Member probiner Posted October 16, 2009 Author Member Share Posted October 16, 2009 Thats good news Andrew. Just so there no confusion, i used the PLG Relax not in the base state but with a Morph (like in the image); that is basicly a freeze from Subpatch.
