  1. hi Andrea! Thanks for your reply. I'm beginner to Houdini so don't know how to use gas linear combination, calculate etc. But I tried to use gas field wrangle and detected that if velocity is zero, collision doesn't work. Anyway I found a way to stop smoke using drag force assigned animation key in Activation. Thanks for your help again and I will use your tip someday!
  2. Hi all ! I'm trying to make a cloud collision effect using pyro solver. so I need totally stopped smoke simulation but drag force in dopnet doesn't work normally. It works very slightly. Smoke spreading speed get slower little bit but that's it. I tried another way to using timescale in pyrosolver. It looks like worked but collision effect doesn't work in slow time scale. How can I get a stopped smoke simulation with collision effect? thanks in advance!!
  3. Hi all, as far as I know, Houdini Engine in Maya could import HDA files for making volume. is it possible in Cinema 4d too? or not? I guess there are no vdb container in standard Cinema 4D so maybe it seems impossible Thanks!
  4. fuel doesn't follow emitter

    Thanks soooooo much guys!! Your tips make work normally!
  5. Hi guys, I need some your help. I'm making torch effect but there is some problem. My fuel doesn't follow emitter and remain in place during few frames. So flames don't be connected, as you can see at my attach files. How can I fix it? I adjust substeps value but it doesn't work. I would appreciate some help. Thanks!!
  6. Hi, can I set all particle's pscale in same size in Filp solver simulation? I wanna get same (or almost same) distance between particles, but there are random distance and I can't control it. any helps or tips? Thanks!!
  7. I have volume with Cd field and want to render this in Redshift. But when I hit render button, it appears just in grayscale and can't see any color. I case of rendering in mantra it works fine. There is a option capable of 'Use Smoke Color' in mantra shader but don't in Redshift Already I saw https://www.redshift3d.com/forums/viewthread/13007/P15/#103643 this page and .hip files but these things are not Volume but VDB. This solution don't include Cd filed. so in doesn't helpful to me. Anyone know what should I do? Please give me any answer of tips. Thanks in advance.
  8. wow.. I missed important thing! Thank you so much!
  9. hi everyone, i'm trying to get a position attribute of particular point in wrangle but i can't. for example, i wanna know point number 1's position attribute. i found 'point' function in vex but this reveal not all(@P.y, @P.z, @P.x) but @P.x only. how can i get a position attribute of point1 separately? is there a another function in vex? please help me Thanks!!
  10. hey, Thanks so much! I really appreciate your help. It works very well!!
  11. How to Stop Jittering Particles

    Hi everybody, Do you know how to stop jittering particles in flip simulation? I wanna make water splash in puddle. I mean splash that made by car on the road. So, I set up initial data as below. but, in Dop network, initial particles shake(jitter) continuously. I simulated to 1000 frame, but particles still shake. How can I stop that particles and start simulation in stable. please tell me whatever you know Thanks so much!
  12. Hi all, Do you know how to remove tiny water drops in fluid simulation? As you can see below, there are many water drops in the air and these are looks weird. I wanna kill that particles, but I don't know what I use among the various attributes. I tried remove points by vector speed, but it's not good result. Is there any way to kill the particles? or should I remove them manually by @ID? or should I simulate until particles looks good? Thanks in advance!
  13. Hello everybody!! I have some question! I want to export my attributes to cinema 4d but I can't. Also I know, when I export mesh object, attributes are moved to cinema 4d successfully. But when I export edges only by alembic, edges are works well in cinema however there is no attributes. Please help me! Thanks in advance.
