rasterise attributes points volume from points

[90okm]

Hi ! trying to set up a source for smoke sim. i use volume rasterize attributes and get strange results. 

please see what's happening

i have a bunch of points distributed across the space. its bound box is rather big (arounb 80x80x80 units)

then i use volume rasterize attributes and get this :

 

as you can see it is very jaggy. of course i've played with pscale or voxelsize/sampling...but i have not managed to get smooth volume

then i deleted lot of points and left only one group of them:

 

the same SOP (volume rasterize points) with the same settings gave me different result (nice and smooth volume)

 

and the question is - why i got different results keeping the same settings both for points and "volume rasterize attributes" SOP ?

the same pscale and the same voxelsize

the only thing that changes is bounding box of my points...

and of course it affects the simulation... i also get ugly jagged volume inside DOP....

i can not understand what is wrong....i thought it is just viewport optimization or something like that....but the simulation also goes wrong and i see this voxels in rendered picture as well.....

how can i get smooth volume for all of my points ? 

thanks in advance

Uhm ! sorry guys!

although it looks ugly in viewport - it renders normal....it seems that it is really only viewport representation

i dunno what kind of bug was it on my first render

Use volume visualiser node to set the max resolution to visualise it properly....

wow thanx!!!

i've never used this option before....now it's fine...
