hello to every one

I want assign Displacement to high res Pyro .

I active rest field in the pyro solver.
set Displacement's Parameters in the Shader and enable displacements in shading tab.

but when I render scene pyro does't has any Displacement effect !

I don't know why !

please check my scene

thanks Smile

hi!
You need a normal field for displacing the volume.

thanks my friend.

but do tou know how I can create normals for pyro ?

[Pazuzu]

You can use a 3d noise from the pyro shader as a normal field, or calculate the density gradient in sops to then reference the vector field as a normal field in pyro shader.

appreciate   the  file,  but   i  make  the render,don't   find  the  displacement yet..... why?  and  if   i  already   rop output  the   sim  bgeo  file   in   low  res,   anyway  can add  noise  to  fill   the  details?like  this...

Hi - I believe this vex function smight work in the displacement field field - it will give you the normals based upon density

N (Volumes) = gradient(density, "extrapolate", 1, "smooth", 0)
