asche Posted August 29, 2016 Share Posted August 29, 2016 Hello ... for a project i need thos very hip effectors like in Cinema or now in Maya Mash But i want to deform many indivdual objects, not many copies/clones, therefore no stamping... so for example you have a scene layout with many small different objects (from maya) and i want a "wave" to go through the scene, deforming the individual objects (or groups in an obj), scaling them, randomly rotating and so on can anyone explain how to do that effect (watched the videos about effectors from Rohan Dalvi already but i am missing some basic houdini knowledge) Quote Link to comment Share on other sites More sharing options...
symek Posted August 29, 2016 Share Posted August 29, 2016 This is not technically required strictly speaking, but practically speaking, you need to merge them all into a single object, what can be achieved with ObjectMergeSOP and some fancy wildcards. It's ridiculously simple to merge even thousands of object from FBX file in Houdini, putting them into own groups etc. After that you can apply any number of deformations you want with a single stream of nodes. Alternatively nothing can stop you from making the same deformations per object (altered with opdigit() expression for example). That would require some scripting if the number is big though. You could post example scene file for inspection. Quote Link to comment Share on other sites More sharing options...
Atom Posted August 29, 2016 Share Posted August 29, 2016 (edited) You can still use Copy/Stamp to leverage Rohan's Mograph techniques. You don't have to use only a single object as the source copy, you can randomly pick from a variety by stamping the switch index as well. And not just shapes, you can use full Object merges from complex SOP networks as sources. ap_copy_stamp_rnd_shape_choice.hiplc Edited August 29, 2016 by Atom Quote Link to comment Share on other sites More sharing options...
symek Posted August 29, 2016 Share Posted August 29, 2016 I think I've misread you question. If you know how to get them into a single object and want to process geometry per group, all depends of what kind of deformation you want. The easiest way is to use Foreach loop, but possibly slow.

asche Posted August 29, 2016 Author Share Posted August 29, 2016 hmmm thats what i am wondering : what is a good way to artistically controll such things ... e.g. 1000 objects in a row, i want to controll the scale with a spline ramp that runs through the objects like a wave...

Atom Posted August 29, 2016 Share Posted August 29, 2016 (edited) You may want to check out Matt's Tokeru page. There are lots of examples. The effectors are farther down the page. Edited August 29, 2016 by Atom Quote Link to comment Share on other sites More sharing options...
asche Posted September 3, 2016 Author Share Posted September 3, 2016 thanks for the help a colleague managed to make this effect for me now ... so, i want to pin this information file (obj) name (name from group , mask *) pack (attribute "name") primitivevop (ramp in Cd) primtiive (scale with @Cd.r) Quote Link to comment Share on other sites More sharing options...
