Dear Forumers, I have an issue with a scene I am doing. I am making a car crash for my reel, and learning how from a tutorial of a helicopter crash by Steve Knipping. I have come across this error: Warning Invalid source /obj/fracture/rbdconstraintsfromrules1/switch_use_proxy Error: Not enough sources specified.. Unable to cook the test input. Unable to cook the test input. in an RBDUNPACK SOP. I have gone through my networks and some options a few times but cannot work out the problem. Any help much appreciated. THANKS Nick PS: I deleted the original geo node with the car fbx to make .hip smaller, my current geo is in a cache and bgeo.sc attached CARCRASHforODFORCE.hiplc filecache_body_fracture_v1.0001.bgeo.sc -
Hello, I have a pre-fractured tree and before porting the parts into dop I pack them all. Even though I check on transfer all attributes included UV My UV after getting packed got meshed up I can use an attribute transfer to bring it back but i dont understand the reason why it happened Is there something I overlooked or is it just the way it is? Thank for reading this ASk_PackedObj_UV.hipnc

Hi, I have a heighfield of 10912 x 10912 px with multiple heightfield nodes using a cop network texture. I try to instance 1,6 millions of trees with the heighfield_scatter node, which is no problem in the scene view, but with Mantra renderer. Mantra eats insanely much RAM, no matter I use full geometry or packed primitives of the trees. The tree loaded as full geometry has 26 MB and as packed primitive 14 KB. The render resolution is 6000 x 4000 px. The maximum number of trees, which I can render without chrashing Mantra is 800.000. I have also tried instancing through the instance node, which changes nothing. Do you have any ideas for another solution as upgrading to 256 GB RAM ? Kind regards System: Core i7 7820X, 128 GB RAM, GTX 1080 graphics card

Like I was trying to generate some cloud by copy to point with one cloud input. According to the help file, packed geometry will certainly reduced lots of render resources because it will ignore the geo outside of the frame, but when it comes to volume, once I checked Packed Instance, all the volume disappeared in render buffer(redshift), there should be something wrong with copy to point ? Or do I have to manually output density attribute ? BTW, is there effective way to reduce volume noise in redshift? Thx !

It is possible to make a similar effect with houdini? https://cs.uwaterloo.ca/~radhitya/repulsionpak/

OK, I have a crowd. I'd like to define a 2D bounding box for each agent from a given camera using the toNDC. I've unpacked the crowd, defined each vertex screenspace position, and now I'd like to put the minimum and maximum values back to the original crowd. I thought some kind of relation between to packed and the unpacked crowd, is it possible?

Hey Everyone! So the issue is... I am using Voronoi to fracture an object. The inside and outside faces are in two groups named 'inside' and 'outside'. I'm using the 'assemble' node to pack the primitives however, doing this, it looses the 'inside' and 'outside' groups which I need to use later on. Is there a way to use the assemble node and keep the groups? Any advice is massively appreciated! Thanks All!

Hi guys , Based on the tutorial Applied Houdini - Rigids II Structure Destruction I'm try same effect , But i have trouble is instance pack , i m use same techniques in this scenes . But i don't know why matrix replace does not work . Hope your help .Thx every body. Please find attached for details

Hi everyone, What is the difference between the "pack" and the "repack" sop ? and why should I use a "repack" instead of a "pack" sop and vice versa? Cheers Ber

hi everyone. i make the angluar velocity in SOP. and inheritied Point velocity in DOP. (i was modify RBD Packed Ojbect DOP like H14. this allow Overwirte attribute.) but, doesn't rotate in simulation. what made the wrong w attribute or i missed something??? i shared my hip. thanks for your read. have good day! w_attribute.hipnc

Hi, all? i'm looking for how to way updating attribute, each frame in dop. i already saw Ryan's shared file. it so usefully for me. but, it seems possible to apply to only one pacekd object in dopnet. (inside dop, if many RBD object(like rbd pakced object, rbd fracture object, rbd object etc....) sop solver doesn't read all object.) how to many object the attribute update in dop??? I shared my hips. thanks. update_attribute.hipnc
