[@BRUTOFX2040]

could you share the pc set up for his kind of big syms??? thanks in advance

[@IDAVFX]

hello Bruto: A decent amount of RAM min 64GIG is good and around 24 threads (12 core) with minimum 3080 RTX or equivalent cards .. . . . I know, its a high setting, but that is also how sidefx is pushing the computation boundaries...and yes, people did even more awesome stuff with much much lower settings back in the 2000s . . . . .

[@CharlieHaggel]

Great tutorial! just one question; what about the interiour faces of the bigger chunks? Where would I fix that?

[@IDAVFX]

Thanks, Allessandro did an awesome job. What do you want to change of the interior faces? Cheers 🥂

[@CharlieHaggel]

@@IDAVFX It looks like, in both the tutorial and in my own scene, the bigger pieces in the middle doesn't get an interiour face. In the highres version that is.

[@emergentlogic8482]

You have to check "Connect Inside Edges" on the Assemble node called "name". It's the node before the null called "OUT EDGE FRAGMENTS".

[@PhO3NiX96]

Isn't it from the trailer of For Honor done by Unit Image on Thinking Particle/3Ds Max?

[@IDAVFX]

hey you are right...................

[@TronLee]

Amazing video! Inside big chunk are not fill geo,it is just two plane,it is possible to fix it?

[@IDAVFX]

sure its possible.

[@0x0abb]

Question? I have some experience with Javascript and blockchain programming...How can one practice to get good at VEX in Houdini?

[@IDAVFX]

There are tons of resources about vex code in Houdini on sidefxs Helpdesk

nice technique but plz tell more about caching this

[@IDAVFX]

What issues do you run into?

[@danielspagnol1370]

Great tutorial, Thanks. So if I don't want to fracture all the pieces how do I approach that?

[@IDAVFX]

You mean a selection you want to shatter?

[@danielspagnol1370]

@@IDAVFX the ground is already shattered with voronoi but I don't want to have edge fragments on some of the big chunks. So yes just a selection.

[@IDAVFX]

@@danielspagnol1370 can you send me the scene file? I gonne adust it for you

[@danielspagnol1370]

@@IDAVFX Yes sure where can I send it? Thank you so much

My PC is Crying 😭

[@IDAVFX]

Yes Houdini sometimes needs heavy resources

[@MananVira]

pls help..... after writing this command " setprimintrinsic(0, "transform", @ptnum, m3, "set"); " my geometry dissappers.. time @43:44... where i m going wrong?

[@IDAVFX]

please, why all the struggle?

[@MananVira]

@@IDAVFX means? m i getting solution for that?

[@romaingaumont6905]

@@MananVira I had the same problem, it was due to the geometry from the DOP low resolution: in the DOP I had to export only the rbd wall without the ground and the collider. Maybe it was the same mistake for you!
I hope it's helpful even one year after!

[@emergentlogic8482]

Check your spelling on the nameOld...I had nameOLD in some places.

[@GymnastEML]

Hi, I’m having a problem when fixing the spelling error at 33:35. When I fix it and click away to update, the partners all still stay at -1. I was wondering if you knew how to help with this?

[@nickwebber9729]

I'm having the same problem.

[@nickwebber9729]

Ok my radius wasn't large enough fine now.

[@IDAVFX]

thanks a lot nick

[@skoklater_rogue]

my object disappears after I write the code in transform_with_lowres

[@skoklater_rogue]

when I write the code
setprimeinstrinsic(0, "transform", @ptnum, m3 , "set");
my object just disappears

[@skoklater_rogue]

Nevermind, I didn't set my Object to rbd_wall inside the dopnet.

[@IDAVFX]

And now?

[@skoklater_rogue]

@@IDAVFX I solved it but I had problems with the voronoi faces still on there

[@IDAVFX]

@@skoklater_rogue awesome, great to hear

[@jackykao3386]

How can you? When even modern science nor philosophy can really proof what a hip file is???
