lemmingsammy Posted February 14, 2018 Share Posted February 14, 2018 So I have a very simple build, consisting of a flip tank and a flip solver with a custom volume velocity plugged in. I'm trying to keep the uvs after converting the points back to a VDB but they don't seem to be coming across correctly. Im using an attribute transfer to transfer them back. Anyone know why?

lemmingsammy Posted February 14, 2018 Author Share Posted February 14, 2018 (edited) Thank you so much for your reply. This isn't exactly what I'm looking for as the uvs don't stick to the particles mesh when moving they just distort ever so slightly. Also alembic exports don't recognise the uvs with this method. The current method (project file) i've got is by assigning the uv onto the points before the sim then reassigning the uvs with transfer attribute... this doesn't work either though Edited February 14, 2018 by lemmingsammy Quote Link to comment Share on other sites More sharing options...
Atom Posted February 14, 2018 Share Posted February 14, 2018 Check out this link. I had to do this a short while back with melting an object using FLIP. Quote Link to comment Share on other sites More sharing options...
lemmingsammy Posted February 15, 2018 Author Share Posted February 15, 2018 Thanks for the reply!Hi this method only works if using the shelf tools. As i have a custom flip fluid this method doesn't work for me. I hate to ever ask but i don't suppose you have a project file of yours too look at. Ive been tearing my hair out for about 3 days trying to work this out. arrrgggghhh Quote Link to comment Share on other sites More sharing options...
empty sign Posted February 27, 2019 Share Posted February 27, 2019 Hey lemmingsammy, how about your project? Did you succeed? Quote Link to comment Share on other sites More sharing options...
amitesh3d Posted July 19, 2019 Share Posted July 19, 2019 Having some issue regarding pre-existing UVs (for example any alembic exported from maya or even pighead) I tried @Atom method of promoting UVs to points and again transferring it back to the vdb mesh. This works fine for default geometries but doesn't work when testing with alembics. I am attaching a test file for the same, please have a look. flip_UV_transfer_001.hip Quote Link to comment Share on other sites More sharing options...
Atom Posted July 19, 2019 Share Posted July 19, 2019 You need to unpack Alembic before you begin processing. Here is a revised setup using a .abc file. There were some errors in your file. There are some UV anomalies, but if you increase the FLIP resolution (which is matched to the pointsfromvolume resolution) the anomalies become less obvious. mb_african_femal_01.abc ap_flip_UV_transfer_001.hiplc Quote Link to comment Share on other sites More sharing options...
amitesh3d Posted July 29, 2019 Share Posted July 29, 2019 Hey Atom, Sorry I got busy with some stuff and could not reply here. The setup worked smoothly, thanks a lot! The only issue which is bothering me and I think most of us is the UV sim issue. There is a paid tutorial which claims to have fixed that, I hope someone could explain it here. Cheers!

KarlRichter Posted July 29, 2019 Share Posted July 29, 2019 A while back i was playing with the UV fluid mesh seam issue with some amount of success. See attached for an example. uv_fluid_mesh.hip 1 1 Quote Link to comment Share on other sites More sharing options...
