  1. Houd could I turn node info off ??

    Ohhhhh So fast solve Thank you very much !! even I saw the tab but I never thought It is right Thank you !
  2. Hi I wanna turn those info off but I cannot find where the option is :S If you know, Help me please ! Thank you !
  3. Random geometry instance to particle

    Hi guys, I made curve flow particles and want to instance it to some petals. I made 5 patterns of petals but have no idea how could I randomly instance those patterns I'll render these particles using Redshift. If you have any idea for instancing 5 geometries randomly, Please help me ! Thank you for read !
  4. OFFF London title's particle

    I've just saw OFFF London titles 2017 at vimeo and It gave me a inspiration. but I'm beginner at Houdini and even don't know how should I call this effect. Is it called like particle advection ? or .. I don't have any idea haha :S And I wanna know basic logic how to make this scene. It is like a grain, fluid, particle or .. I don't know wow .. Please help me to learn new things !
  5. I want to delete some of my topics. but there is no button for it. How could I do it ??
  6. I made some simulations with RBD and had some problem with density of objects. so, first at all, I just made this simple scene and can't understand how does this sim goes. At Gif, Left ball has 1 density, and Right one has 10000000 density. but look, It looks very same with each ball :S What should I add for this ?? I made house scene so I wanted to set up density of TV has high level, and some pictures on table has low level. but It seems very same like that scene. Help me ! Sorry for my poor English and Thanks for read
  7. Thank you for your example, I've forgot that there are many resistance things in real world. So, How could I match thoes things in real world ? If there is 100kg ball in the scene, How much do I have to control its density ? I can't estimate that issue in Houdini ,,, Do I have to just see the simulation and control it ?
  8. Thanks for reply, but after this, I tested for it by moving box. box push the balls and I expected that heavy ball will move more slower, but It didn't.. Only when I set up those density as 1 and 100000000000 I can see difference of it .. That huge amount ..the difference just looked like plastic and plumb. It doesn't seemed 1 and 10000000000 of difference
  9. Redshift and Particle Render

    Here's a problem with Redshift render :S I made particles and wanted to render it. but When I make particles to mesh by using Redshift OBJ Parm(Particles tab -> Render Object as Particles), I can see motion blur on rendering but It cannot be used as geometry light. I set up the geometry light with rslight(change Light type to Are and link Mesh object). So, I copyied spheres to particle points instead using Redshift OBJ Parm, and that moment, I could use it as Geometry light. How could I use both ?? so, problem is 'I want to use particle spheres and wanna us it as geometry light too' Sorry for my poor English and Thanks for read
  10. Alembic export and Textures

    Thank you for idea ! I solved it I set up my node tree as same with before, but just one thing different. I wanted to assign object's own uv&texture. so get into each object's unpack node and transfer 'path' attributes. and then transfer 'path' attributes again at pack node which is under the unpack node. finally, each objects could have there own path attribute and so It can be connected with each's path Thank you for your idea again and have a good day !!!
  11. Hi ! I have some problem with export :S I imported alembic file from C4D to Houdini and simulate some props. then, I cached that simulation and export with ROP Alembic Output node. and when I import that abc file at C4D, All textures gone T_T Where Do I have to add Rest position and UV texture nodes ?? It is too difficult to me Help me ! I set up my nodes like this. Imported alembic file -> blast props -> unpack each prop, add rest position and uv texture node -> pack -> simulation(DOPNET) -> file cache -> convert node (If I didn't add this node, Houdini get fatal errors) -> ROP Alembic Output. At the pack level, I added ROP Alembic Output and export it for test. and It works ! but when I finished simulation and cache it, use convert node and ROP Alembic Output nodes. Its Textures are gone T_T How Could I do ?
  12. Alembic export and Textures

    Thank you for reply ! but If I add unpack node, use ROP alembic output node, Houdini gonna be crashed down and I don't know why ...
  13. 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
  14. 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
  15. 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
  16. 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
  17. How could I render wire at Redshift ??

    Thanks for help, I looks nice
  18. 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
  19. 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 !
  20. 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 !
  21. Random shooting box

    sorry .. but I can't understand what you meant T_T I'm so beginner with sort of wrangles , vops like ...
  22. 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
  23. 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
  24. 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 ?
  25. 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)
