Malcolm Zaloon Posted February 19, 2014 Share Posted February 19, 2014 Hello guys. I´m need put a stable UV on a changing polycount alembic source. (the alembic comes from other software, and have increasing geometry until frame 12, after this polycount is stable) my idea is: 1.get two alembic node from same source, first normal linked $F and another reading only one frame (frame that contains all final geometry count already) 2.create a uv attribute on first and on second i project UV as i will need. 3.transfer UV from second "static" alembic source to first "dynamic" alembic. the problem is, on step 3, it´s not working, UVs appear stretching on a crazy form. i believe that problem is because polygons have changing order, but not sure.. and i don´t know how to correct this. Can someone help me? thanks! Quote Link to comment Share on other sites More sharing options...
abvfx Posted February 19, 2014 Share Posted February 19, 2014 (edited) Stretching like crazy? Like they are welded? Are you making sure your uvs transfer to and from are vertex attributes not point? edit:// do you need the second uvtexture? If you are transferring uvs from one object to another the target object doesn't need to initially have UV's?

Malcolm Zaloon Posted February 19, 2014 Author Share Posted February 19, 2014 (edited) yeah, its vertex... need be points? with middle click always show UV as vertex attributes. i do not know what to do make this work. here is how UVs looking crazy.. note only frame 12 appear correct, but its same of the reference UV (static alembic frame 12) Edited February 19, 2014 by Malcolm Zaloon Quote Link to comment Share on other sites More sharing options...
Malcolm Zaloon Posted February 19, 2014 Author Share Posted February 19, 2014 On XSI i just copy uv from one to another, and even with polycount variating, if static reference contains all polys, all work perfect. just new polys appear gradually on UV in correct places.. but i´m migrating to Houdini, and i need to solve how to do it right on SOPs.
