Ridiculous GUI issue Jan. 10, 2013, 1:12 a.m.

For what it's worth, and as a public service factoid, I was having similar troubles on my old mac. Houdini 12 glitchy, artifacts and extreeeeme slowness.

Mac1,1 (2006 quad core mac pro), ATI X1900 graphics card, Mac OS X 10.7.5.

Got ATI Radeon HD 5770 card from Apple store, works great (yes even in this old computer), Houdini 12 is now running great. (A newer computer will still help tons for rendering I assume… but at least back in business for authoring!)

Edward – thanks for the note.

I did indeed recreate from scratch, in both 9.5 and 10. Finally found the magic, from the FillGlass example in help.

I confess, I dont fully grok DOP networks. Like, why can Gravity go anywhere? It seems like some nodes just “pepper” the data stream, and the network itself (after output) does the heavy lifting? Something…

Anyway, moving the static object Merge-Source-Relationship to *after* fluidsolver caused the static object to act like the fluid spigot. (In 9.5, static object worked fine to go before fluidsolver.) For now, that's enough to go forward.

Oh, and RBD object (without rbd solver) works fine in either place.

But any pointers on how to think & reason about a DOP network, most appreciated! The upstream/downstream data flow is not obvious to me…

Hi Manu – Thanks for replying!

Any thoughts on why the fluid source (staticObject merge-as-source fluidObject) would only have volume on 1st frame?

I see you're pretty fluent on Dynamics…

(As for H12… alas I'm on a Mac with 5 year old ATI graphics card, I have all updates but maybe even that is not enough. Forward!)
