You may be triggering an evaluation without realising. I suspect the open GL glitch may not be it. Try deleting lights and others elements than interact with your simulation as these, being visible may force a full re-evaluation. Jb Sent from my iPhone > On 18 May 2017, at 18:58, Andy

And here's a full vop version, using MakeSpaceTransform and picking the object from there. The Gif compression ate the violet color, but MakeSpaceTransform outputs a matrix4 ;) [image: Images intégrées 1] 2017-05-18 20:33 GMT+02:00 Olivier Jeannel : > Again for the Matrix

Re: Houdini Basics....

Again for the Matrix from obj level : In a Wrangle : matrix m = optransform('/obj/null1'); @P *=m; Found the solution at tokeru : http://www.tokeru.com/cgwiki/index.php?title=HoudiniVex#Get_transform_of_objects_with_optransform 2017-05-18 20:26 GMT+02:00 Olivier Jeannel

For the Matrix from Obj level http://forums.odforce.net/topic/15262-how-to-get-world-coordinates-at-the-geometry-level/ There's an opxform_vops.hip to download. $out1 = optransform($next); The autor uses an "inline" vop, which is new to me, and it has a fat documentation :/ 2017-05-18 19:58

Re: Houdini Basics....

Yep, I think there’s a sneaky bug in there somewhere. I’ve had it when I’ve got all my objects hidden it still evaluates the DOP network. My suspicion was that it might be related to the bug where Houdini shows an object in the viewport you can’t get rid of. You could try killing the Scene

Re: Houdini Basics....

Not a specialist of these geo to sop manipulations here. But, if you "object merge" the null (/obj/null1/point1), with Transform "Into this object" you can have access to its "P" position. Surely there's a good way to have the full matrix... 2017-05-18 18:58 GMT+02:00 Thomas Volkmann

Re: Houdini Basics....

Probably a messy setup the DOP is inside a SOP with stuff connected on in and out. It works in another scene BUT while we are at it: How to I get the global position of a Null into a VOP? I'm trying with "$mat = opparenttransform("/obj/null");" inside an inline but it doesn't work

Re: Houdini Basics....

Setting the DOP in question to bypass doesn't work for me. <-- I think this should work? On Thu, 18 May 2017 at 12:52 Thomas Volkmann wrote: > I'll be damned!! > > But knowing how to do it now wins over the embarrasment :) > > Thanks a ton! > > > "Andy Chlupka

Houdini Basics....

Even at the risk of annoying you guys: How do I stop a DOP-network from cooking while scrubbing the timeline? In Softimage I just hide the pointcloud and I am good to go. Setting the DOP in question to bypass doesn't work for me. User error I guess... but please shed some light! Thanks and
