Extract animated relative inverse transforms?
ItsMeM replied to spf987's topic in Animation & Rigging
Im glad you found it helpful! by the way, animated checkbox often makes things slow if geometry is heavy. You can use bake button which will generate point of each frame and save xform attribute on it. Then it will be much quicker to work with geometry! (don't forget to reupdate bake if animation is changed). -
Extract animated relative inverse transforms?
ItsMeM replied to spf987's topic in Animation & Rigging
Hi @spf987! I have a node that i have created to stuck geometry to center of the world, if your topology is static. You can take a look at it! UM_FreezeToCenter.hda edit: if you check invert transform under transformation tab, you will have stuck geometry to origin based on point you have pick. Then you can put attribwrangle, with "sun" geometry in 1st input and "earth" geo in 2nd with 4@xform=point(1,"xform",0); to pick up xform and just use transformbyattribute node to transform sun with that "xform" attribute. hopefully I have understood well what you need. P.S. I have uploaded it to orbolt some time ago, but i think it's locked. I have uploaded you file so you can take a look at the vex. its very simple! https://orbolt.com/asset/UM_::um_negatetranforms -
Hi Marc! Thank you so much! I've just come back to check and seen it implemented! I'm very happy and thankful that you have implemented this!

Hi! I wonder is there a way to have odforce forum in my rss feeds? Did someone figured out the best way to have it? I have tried to append /feed and /rss to the link, but it looks like website doesn't have rss. I would really love to have it configured! Thank you for your time!

I'm not sure if its right. Its two streams of data. They may not see each other (not having interactions). You should use fetch data node to move data between different streams so they can affect each other. You can use multisolver to put everything in one stream and it should be fine. Correct me if I'm wrong.

They are soo beautiful!! Congrats! Natalia, you nailed it! Congrats <3 -
how sure you are that orient is properly built? Did you normalize values before creating quaternion? If you take points from sim and use transform pieces node, you can transfer initial orient and qmultiply it with dop orient to correct it.. inside pvop you can have qmultiply node or in vex qmultiply();

On flipsolver you have reseed tab, there you have temporary particle count on each voxel. That one helps you with getting mesh smoother, especially with high viscousity fluids.. If you pump up Particle per voxel parameter, it should solve your issue. Enjoy!

Try storing original path string and after fracture and sim export geometry with `Build Hierarchy From Attribute` on alembic output.

Amazing! Thank you for good thread! Do you guys know is there a way to create cluster with gas part to fluid? Or cluster inside DOP with sopsolver or something (density don't have to be created with gasparticletofield) I'm exploring dop at the moment and what I had in mind is that from each impact of rbd, create source for popobject and fetch that data to smokeobject.. So, if I want to create more then one source, I get into an issue with smokeobject size .. I posted thread a day ago, if you have a moment, take a look. Thanks in advance! Best Regards, M

Hi Friends, I need your help!! I'm playing with DOP, trying to understand it and feel comfortable working with data.. I come across one issue that I have trouble with.. Is there a way to create cluster grid inside dop? The problem is that I need to timeshift whole range to get initial data for clusters.. Here is the hip file, you can take a look.. I would appreciate some extra feedback about the way I approached with this setup.. I'm I doing something wrong? Thank you!! Regards, M in_dop_clustering_help.hipnc

if you need to stay with a tube, maybe this will work? FindthecenterTest_vex.hip
