Oh yes! nice tip Andy. Used to adding pop on with RBD (bullet) but makes total sense you can add it to fluids now. On 1 June 2017 at 23:47, Andy Nicholas wrote: > Hi Cris, > You can save yourself a step and just directly use a POP Wrangle DOP or > Geometry Wrangle DOP.

Re: Houdini Basics....

Hi Cris, You can save yourself a step and just directly use a POP Wrangle DOP or Geometry Wrangle DOP. No need for the SOP solver. Cheers, Andy > On 1 Jun 2017, at 22:57, Cristobal Infante wrote: > > You can do this easily with a sop solver in dops. > > - Turn create Age

Re: Houdini Basics....

You can do this easily with a sop solver in dops. - Turn create Age Particles, so we can get an attrib age. For 25 frames for example, the age will be 1. - Add a sop solver that goes in the marge with the source - Inside the sop sovler: dop geometry -> attr wrangle and add the following code:

For some strange reason I can't post to the houdini mailing list, so it's you guys once more A simplified use case of what I want to do: Take the Drip Particle Fluid shelf tool, and set the velocity to zero on all particles that get emittet after frame 25 so that they stay at the same place

Re: Houdini Basics....

This is the VOP-Intersect node https://www.sidefx.com/docs/houdini/nodes/vop/intersect . I'll keep the normals issue in mind, thanks. Anyway, is there a way of viewport debugging as in ICE (show properties)? I'm using print to show the values in the console atm, but that doesn't work really

Re: Houdini Basics....

the intersect node in VOP ? If I remember correctly, beware of the length of your normals, they had to be long enough to "hit" the surface. ie don't normalize them. Yeah, Houdini is deep, not always easy.. 2017-05-19 8:53 GMT+02:00 Thomas Volkmann : > Thanks guys! > >

Re: Houdini Basics....

Thanks guys! I also found the transform node to do what I need 5 minutes after sending the mail. It wasn't obvious just from reading the description that you can use it to simply get the transforms from any object, it sounded more like a converter node. BUT...here we go again: 1) Why are there

Re: Houdini Basics....

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

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

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
