  1. pyro colliison doesnt work

    Hi Arrev,thanks for your tips.i have been looked your file and the smoke moving nice at the begin ,but when the collision object stop or something else force in there,that made hard to control it. I think the smoke will inherit velocity from the collision object(add its own velocity) and spread around.(maybe i was wrong) I will keep trying on it and any advice is useful for me,thanks.
  2. pyro colliison doesnt work

    Hi jayden,thanks for the reply,but when i disable correct collision nothing has changed.i dont know why the smoke doesnt collide with moving object,it looks werid. sorry, i found another "correct collision" in the relationship tab,and when unable it the result had a better motion,but the smoke did not keep up with the collision object.I dont know how to fix that.
  3. pyro colliison doesnt work

    hi, i work on pyro collide with a moving object now,and i found some posts about the pyro collision on odforce,but no matter i use static object with PCG or collision volume with multigrid,pyro just like be "eated" by the moving object ,as a sink field.i try to increase the supstep but it doesnt have a right look . sorry for my bad engligh, here is a file what i want to say,anyone have some tips? pyro_collision.hip

  11. Hi,guys I'm trying to displace the fracture objects,I want to displace only the inside pieces,the edges between outside and inside keep stretch along the outside face,I used point cloud to define where the places influenced by displacement,but now the edges does not displaced along the inside parts,thanks for any help!

  15. Hi, I have a ocean plane with the displacement shader using hot tool,I want to deform the plane but the displacement texture can't changed with deformation.I don't use the hot toll with sop because it needs a large subdivide for rendering. How should I do this?please give me some advise, Thanks. there is my file. deform_ocean.hip
