  1. How could I make this dynamic ?

    Hi ! I'm a beginner of Houdini and I have no idea how could I make this... If Box on top is moving front, back, left or right, Tube and sphere has to be moved too. but the Tube has to move like wire(or something like a rope) and so sphere attached at end of the wire. Like this image, bulb attached to rope and rope attached behind of celling. I did some ways to make it, used pin constraint and spring constraint but I don't know how could I attach those objects. If you help me, I will be my big big pleasure ! Thank you for read and sorry for my poor English. Have a good weekends !! bullet-bulb-industry-ceiling-pendant-with-black-cord_1427692337841.webp
  2. When I do some simulations like pics at bottom, Scene view become crazy like those .. I imported alembic files and set their position. but If I do simulations with dopnet, They are gone to randomly strange position like secone pic, and going to be black like first pic. When I delete scene view and make it new, It looks like when I set up. But I have to see that simulations preview and these problems make me crazy :S Help me with this plz !! Sorry for my poor English and thanks for read Have a good day
  3. How could I deal with height of flame ??

    Thank you for reply , but I wanted to scaling it down. but when I scaling it down, smoke also being down scaled.. I can' understand how does Houdini caculate those options on cumbustion or simulation tabs T_T
  4. Hi first, I'm beginner of Houdini and I'm just challenging to control pyro without shelf tool (I mean, pile nodes up from bottom) But, Even I use shelf tool, It is still hard to deal with flame height, amount of smoke and etc .. First of all, I wanna make fire of match and that flame height makes me to be confused .... I controlled options at combustion and simulation tab at Pyro solver but I can't understand it yet ;;; How could I deal with this ?? Sorry for my poor English and thank you for read ! Have a good day
  5. How could I render wire at Redshift ??

    Thanks for help, I looks nice
  6. Hi guys , Recently I followed some tutorials and made this guy. but when I start render at Redshift, It is too thin that I can't see. Just like this T_T When I rendered it in Mantra, It looks like has thick wire rightly, but I don't like this look. So I wanted to render this man in Redshift and looking for some clever guys giving me some tips about it. Sorry for my poor English ! and Pleas help me ! Thanks for read and have a good day
  7. Hi ! I just wanted to familiar with Mantra renderer. but It takes my time too long that I'm now just considering to buying Redshift or Octane .. Of course I know Mantra is cpu renderer. but I just added glass sphere and metal face modeling in the scene. and It takes about 5~8 minutes (default mantra setting) Did I have to do something ??? If you have some tips for Mantra rendering .. please let me know T_T and I want to know why houdini users love this renderer. I'm beginner of Houdini. Help me please !
  8. Random shooting box

    sorry .. but I can't understand what you meant T_T I'm so beginner with sort of wrangles , vops like ...
  9. Random shooting box

    Hi guys , I'm totally beginner of houdini and I'm stucked with some problems. I set up boxes randomly in scenes, and want them to shoot at same direction. I mean, some box goes to X-axis at 3 sec, and some start to go at 6 sec like that. Here is example, I want to shoot boxes randomly to blue arrow direction. But I don't know How do I deal with Id(?) or that boxes point numbers T_T Please help me !
  10. I emitted particles and I want to make them stopped where I want. To solve this, I emitt particles and use popgroup node(Bounding and use Bounding Object). when they are into bounding box, group:groupname attribute become 1 and I made pop wrangle behind the node and wanted to make their velocity to 0 But How could I control that group:groupname attribute ?? and If I solve that, particles will be stopped and make a line. but I want to make them spread in the bounding box... Please help me.. sorry about my poor English thank you for read
  11. Hi guys, I made several text by font node and I want to pop out them randomly. I thought about that make some variable to each of them like 1,2,3 and rondomly selecting in wrangle node. but I have really poor logical thinking and It is taking lots of time. Help me with it plz ! Have a good day and sorry for my poor english too :S
  12. problem with Merge node-glue constraint

    I finally fixed it to solve it, I compared all shelf-made(glue constraint) nodes with my hand made nodes. shlef nodes uses 'Attribute String Edit' node. Inside of it, at Editor tab, they write `chs("/obj/its dopnet name/rbd packed object name/object_name")`/*. for making 'name' attribute to 'its name'+piece number so I write it same and finally I can control each object's glue strength. now I'm wondering about Attribute string edit node and 'chs' function. could anyone explain about it for me ?
  13. Hi guys I make some scene with using RBD fractured objects. That is screenshot of simple scene and I have some problem with this. As you see, I made the desk and chair and make those each glue constraint in their node too(with different constraint name and type. Not in screenshot but I made each's constraint networks and glueconrel node. I connected each nodes just like when I made it by shelf tools, but It didn't work. (I saw tutorial about constrain and made this scene differently with when I make it by shelf tools.) and I could find why it didn't work. At that screenshot, when I put Chair node into merge node on top first input, Chair's glue constraint is work. and when I put Desk node into merge node on top, first input. Desk's glue constraint is work. It doesn't matter constrainnework's Sop path or glueconrel's Data name. How could I fix this that merged objects follow each's constraintnetworks and glueconrel ??? Thank you for read and sorry for my poor Englis. T_T Thank you ! (I changed options in the merge node like Affector relationship and relationship, but It didin't work :S)
  14. How could I refine this interpenetration??

    OMG What t.... I turned on this post's notification but It wasn't activated omg .. Thank your for you guy's helps
  15. Hi I'm just studying about RBD solver and its fracturing with first picture's object. and When I setup those with solvers (rigidbody solver and sop solver will be added), I could find some interpenetration in it. Those boxes were having interpenetration, so I've looking for some tutorials about it. and I found 'Glue constrain' but that tutorial used it for fractured(and packed) object. Does 'Glue constrain' be able to used in my situation ?? Thank you for read and always sorry for my poor English. Have a good day
