ya know, i have no idea what the heck i did yesterday.. i'm redoing this again now and you're completely right mark.. if the solver is inline, then the parm get's disabled.. And if you try to attach it as foo, it busts.. (well it doesn't “bust”, just doesn't recognize it as a solver anymore.. details just see it as a new piece of data called ‘foo’..)
god knows what setup i had going on, but i was messing around with multisolvers left and right yesterday so maybe i just cheated and had a single renamed rbd solver attached to a multisolver that was inline after a rbd object->gravity setup.. but of course that was working because the multisolver passed along ‘Solver’ with subdata as ‘foo’ or whatever.. so i dunno, but i wouldn't change it now that i've looked in to this farther. it's like you said, it just depends on which situation is more common and i guess i would rather keep it as is now since many solvers will be put inline. sorry ‘bout all that.. ops:
just thinking out loud.. maybe something can be done when you toggle “unique data name”.. maybe it changes the data name from solver to opname.. but no, that just may confuse some people.. hmm.. well i can’t think of a better solution so all seems to be well. i would leave as is and i think it's safe to just ignore all my ramblings as usual. :roll:
thanks for the clear up mark and craig..

You do? If I understand this correctly, when I build that network, I get a Solver that contains data called Solver, and in fact it doesn't work properly unless you I toggle “Unique Data Name” on either the RBD Solver or the SOP Solver. Because otherwise, they are both named Solver, and only one gets used.
yea, sorry.. i guess i should have been more specific.. you are right, without the unique data name toggled, the multisolver will only pass through the last solver piped in to it because of the naming confliction.. the situation i presented above assumed that checkbox to be on.. sorry about that..
I think you are inadvertently solving your problem by naming one solver “foo”. That way, they have different names and both get used.
actually i was just using foo in place of a simple single rbd sover sim that i mentioned above.. it was in response to mark saying “If you attached an RBD Solver to your objects but give it the data name ”foo“, your objects won't solve. ” But this wasn't the case and it worked just fine. Plus I don't understand why there would be a name parm in the first place if we couldn't change it..
If I check the “Unique Data Name” toggle on both solvers, then I get a pair of solvers named
Solver_multisolver1_1
Solver_multisolver1_2
Yes, this is true, and is what i was getting about above. These names are useless when browsing the tree. Unless you select them and check out their datatype or remember the order in which you piped them in to the multisolver, you can't quickly determine which is which. So if the default data name was “`opname(”.“)`”, you would be fine with or without the “unique data name” toggle. Without it would show rbdsolver1, sopsolver1 and with it would show rbdsolver1_multisolver1_1, sopsolver1_multisolver1_2.. either way, seeing these names listed in the tree helps identify which is which immediately..
unless changing the name does break it somehow like mark says, then all of this would be thrown out the window..

The issue with the Dtails View scrolling on it's own is already in our database. However if there is a specific value you are monitoring, select that value in the tree view. That value should remain selected and in view even as you play the simulation.
Yup, a selected value in the tree stays no matter what, so that's atleast a good thing.. Maybe we should be able to select/highlight specific properties and it could stay with that as well.
The reason for the name “Solver” on all solvers is that DOPs finds the solver to use for an object by looking for the data named “Solver”. If you attached an RBD Solver to your objects but give it the data name “foo”, your objects won't solve.
Hmm.. wasn't aware of that.. But i just did this and it was fine.. Simple RBD Object->Gravity->RBDSolver->Merge with ground plane.. Data name for solver was set to “foo” and nothing seemed to break.. Unless I'm missing something.. :?
I'm not sure what you mean about hunting things down in the details view. What is it that you're trying to find, and how would having a different name for the solver data help? If you are trying to find all objects which are using a particular solver, I would suggest naming your objects so that they give an indication of what solver is being used on them (e.g. the object named clothobject probably has a coth solver attached to it). Would this not accomplish the same thing?
Yes, naming objects according to solvers is appropriate but I guess I was more so getting at a single object with multiple solvers attached to it rather than the other way around. For example, say I have a RBD solver and a SOP solver piped in to a multisolver dop that is attached to an RBD object.. If i go to that specific object in the Details View, I get two identically named “Solver_multisolver1” entries with the only way to determine which is the RBD and which is the SOP is by selecting them and checking out the datatype property. If i name the data correctly in the solver before hand, I can just quickly view and know which one is which by browsing the tree.

Thanks for the reply Mark.. I'm pretty sure the drivers on both sides are solid and they're definitely not the latest bleeding edge ones.. I'd bet it's completely due to that bug you mention as the windows build is 412 and the Suse one is 422.. So I'll def grab the latest one for windows and try it out. If i see any more problems, I'll be sure to let you know..
Thanks..

These two really don't like to mix it seems I mean, Houdini would crash with windows before, but atleast you could retrieve a backup file from your $TEMP and it would warn you about it all. Now with DOPs, it's happening all over the place.. And when it happens it's just gone. No errors, no warnings.. Just poof and you're done for.
For example, open up help and load in the visualizeimpacts example from the sop solver. Now go and try to uncheck the ‘add impact’ parm in the rbd solver. Boom gone. Better yet, go load in that example and just try to delete the obj network that is created. Boom gone. Now this may be due to my build number being outdated (412), but i don't get this at all on Suse.. And it seems to happen on a number of different occasions (which may all be non existant anymore due to bug fixes in recent builds).. Now, I like linux as much as the next guy, but sometimes i may just be at a windows box and too lazy to reboot to try something out real quick. That or I may be needing windows only software at the same time.
So yea, is this a windows thing? a memory thing? a bug thing? is it still happening on recent builds? For windows users out there, have you noticed a difference in stability as well since H8 and has it been getting better with the more recent builds?

The scroll bar in the details view resets to the top whenever changing frames or parms that affect information being shown.. Man is that frustrating.. especially when you have a desktop with a thin details pane in it. Say you want to monitor your values in the vel field under an objects position data.. It's way at the bottom and when you want to either scrub back and forth or just compare one frame to the next, the dang window jumps right back to the top.. I would really like to see it just stay where it is while working so i can monitor whatever it is i need to.
Also, this is just a suggestion, but I would also change the default data name parm on solvers to “`opname(”.“)`” instead of “Solver”.. i realize i can set it as a permanent default myself, but I don't see why it wouldn't be a good idea to do this from the begining.. “Solver” just doesn't cut it when hunting things down in the details view..

hey mario,
would be cool if you wrapped your glass shader up and put it up on the exchange.. i'm sure a lot of people could put it to good use and may never see this thread..

The reverse sop works strange, it doesn't really reverse normals. I'm not sure what it does?
The reverse sop changes the vertex order of your faces by either reversing or shifting them. (you can actually do the same exact thing right in the primitive sop.. never understood why it really exists to be quite honest.. maybe less computation than the full blown primitive?)
to best visualize what's going on.. turn on vertex numbers in the viewport. lay down a grid sop and append a reverse/primitive sop with appropriate parms. then keep bypassing/unbypassing it to see what's happening..

and just for future reference, the “export”ing the quote was talking about was exporting the channels back to your appropriate parms (probably bone rotations in the particular case).. this can be done either through the export chop or the orange export flag on the last chop of your network (i suggest using a null chop if you don't go the export chop route..)..

Hey Peter,
This may not be such a good idea because it will probably affect the whole sim including the way your character moves off of the table, but could you maybe alter the table's mass/density for a short amount of time so that it flies away faster? I know this isn't what you're wanting and is a cheap hack, but thought I'd throw it out there.. I'm still interested in your original question though. (i.e. how we can affect these properties/attributes we see in the details view like a point sop would be doing in sops..)

Windows XP SP2 (haven't tried this on on Suse yet)
H 8.0.412
If you use “” in searches in the docs, it seems to work great for multiple words. But if you turn on “Mark search items” it seems as if it actually looks for the “” as well in the doc to highlight.. Any chance of getting this fixed? As a workaround for now I'll search with quotes and then take them away when needing to highlight. But it'd be nice if the mark function could detect if the search string is quoted or not, and disregard them if it is.

hey andre,
on the left of the viewer pane there is a tow away bar with selection and handle options.. the one that looks like a yellow cube (hotkey -) is the select whole geometry button. a few below that is your front/back selection (hotkey b).. however i find that paint selection mode sometimes works best when selecting only front points…
i also suggest that you go over the UI help documentation.. a lot of these things are explained in there and will get you up and running faster than waiting for an answer on the forums.. Both ‘Getting started with Houdini’ and ‘Houdini Basics’ are both great sections to check out.. Also, don't forget the search function.. A quick search for ‘whole geometry’ gets you right where you need..

thanks jeff.. sounds great. i think it will be a nice feature for a popnet in sops.. as well as popmerges to respect the network they are referencing (or have their own param with a default relative ref ch() expression to the one it's referencing). Rendering to disk is actually what i've always done before.. it wasn't really until dops that i started enjoying caching so much so i started to question pops and their ability to do it as well.. Just the scrubbing aspect alone sells it for me rather than the playback performance.
Thanks again..
Thanks again..

so basically any pop networks or pop merges in to sops can not be cached without a cache sop afterwards.. just seems odd.. i would think that most people would have their pop networks in either sops or dops (and the dops popnet has a cache param).. and even if i add the cache sop, i'm still stuck without it while i'm working within the pop network..
is adding the cache param to sop popnets and popmerges (well atleast having the popmerge respect the cache settings on the network it's referencing) on the list of things to do? and if it isn't, can I RFE that?
thanks twod

why is it that pops aren't cached? i realize that i can pop merge or have a pop network in sops and append a cache sop, but why not just have it natively through pops with access to configuring it through the cache manager?

It would be nice to be able to save geometry directly from gplay for convenience of format changes.. i.e. load in a sequence of obj's and you want bgeo's exported out..
Sorry for yet another RFE, sesi.. It feels like there's atleast one posted each day anymore. I suppose once a new version comes out, we're all excited about new features that our minds are just on a roll with a ton of momentum.. 8)

hey peter,
i actually just got this to work on my dual monitors.. and i bounded it to my hotkey from a link in the k menu. so now i can launch houdini maximized (with max/restore button!) and only on the primary monitor as quick as a ctrl-alt-h.
thanks for the tip JC…
for mine it was:
houdini -geometry 1280x960+1280+0
