  1. Control stiffness for constraints

    Hi Guys, I would like to understand how it is possible to control the stiffness for constraints. I know for FEM there are extra attributes and also for Wire objects. But if I want to create a piece of metal with hard constraints(or other constraints) it is not that easy .Currently I simply control the rotational stiffness on the object.But I would like to control it in the hard constraints. Is there a good way to fake the stiffness in the constraints, with a sop solver for example? Thanks for your help guys
  2. Artifacts in Volume

    @iamyog thank you very much. i heard about it. But i forgot it. In mplay are the same problems. I have to use the depth map for a task thats the problem. Have anyone an other idea?
  3. Hi Guys, i have a weird problem. When i render a cloud with depth map shadows everything looks great in render view.But when i render about mantra node to hard disk there a some artifacts. fThe Light setup is a sun light and a shadow map of 4k. I changed every settings in the shadow tab, like bias,blur,quality... But nothing happen.When i change the light position, the artifacts appear on a other place. So i think there is something wrong with the light. Has anyone an idea what the problem is?? Here a both pictures: Left: Mantra Node Right: Renderview
  4. Hi guys, In DOP i use a cone twist constraint and a sop with angle and torque for break the constraints. The Problem is at Frame 2-3 the angle value jumps to an value like 4.18879 or to value like -1.#IND . The Object doesnt move in this Time. Has anyone an idea what i do wrong? Here is a Example Hip. I hope anybody can help me. Walltest.hip
  5. Viewport Volume Problems

    thanks for your idea but its turned on and nothing happen.
  6. Viewport Volume Problems

    mmmhh No ideas? Are there any settings for the Viewport quaility for Volumes?
  7. Hi Guys, when i create a Cloud Setup from Shelf. I get this Viewport Problems. If i create a new Scene View it works for a while.But after some mouse cliks i get this problems again. Has anyone an idea how i can fix it?
  8. Hi Guys, can anybody explain me, how i set my goal_twist_axis in sop?? I use houdin 15 I create a attribute vop and for example i connect a "parameter node" with a "add attribute node".i call the attribute "goal_twist_axis" ,the Local variable name is GOAL_TWIST_AXIS. Attribute class is primitive and type info is normal. The parameter node output is vector. In the spreadsheet everthing looks good.But it has no effect for the constraint in the dop. I hope anybody can help me.That would be great.
  9. How switch active attribute in dop

    Hi Guys i have a simple scene. I have a fractured object and i set the active attribute to 0 . A sphere fly through the fractured object and every touched pieces switch his active attribute to 1. In sop it works fine.But the problem is in dop nothing happen. So no piece fall down. I tought it works with "Overwrite Attribute from Sop". What do i wrong? I hope you can help me Thanks in advance
  10. Cloud Light Help

    Does anyone have an idea?
  11. Cloud Light Help

    Hi there, is there any tutorials for the cloud light? I want to use the cloud light as a replacement for scattering.The problem is i use a cvex for displacment and want to implement the cloud light data in cvex or after cvex. Does anyone know how i combine this together? I am grateful for any help
  12. Hi Guys, Is there any way to export Fluid with color attribute to modo? With Rf mesh export in Houdini and emreader in modo it works very well.But I can't get the color attribute. Has anybody an idea?
  13. Emit for 3 Frames

    mhm ok.But how can i create a global variable in a pop .I create a pop wrangle and write : addvariablename(1,"age","AGE"); and in a pop vop Activation field i write: if ($AGE>0.2,0,1) thats for an other example but the same problem.It doesnt work.
  14. Emit for 3 Frames

    ^^thank you,thats the simple way.The problem is i build an digital asset and in every scene the collision is on a different frame.so i want detect the collision frame, start emit and 3 Frames later it should stop.
  15. Emit for 3 Frames

    Hi Guys, i have a question.how can i realize that 2 objects after collision emit particles for 3 frames and then stopped. i started with an if statment in the impulse activation but i cant use any attributes.Hope anybody can help me. Many thanks in advance for your help.
