Simple move-to-center python scripts change packed geometry shape...
bunker replied to biller's topic in General Houdini Questions
seems like a display issue, try creating a new sceneView or use unpack SOP after the blast node. -
very rarely, last time I did that was to grab a useful VEX function from the old Pyro1 Shader (SoftClip) PS: did you completely replace your original post?
-
you could just separate the 2 pieces before the rbdcluster SOP: Cluster_Problem_2.hiplc or you can make your own clusters: Cluster_Problem_3.hiplc

Which VEX noise function is suitable to create cellular noise?
bunker replied to Masoud's topic in Scripting
float dist1,dist2; wnoise(@P * chf("freq")+chv("offset"), chi("seed"), dist1, dist2); @Cd = dist1; -
if you use a attribwrangle and plug the bounds in the second input, you can do this in vex: vector bmin,bmax; getbbox(1,bmin,bmax); if(@P.x>bmax.x || @P.y>bmax.y || @P.z>bmax.z || @P.x<bmin.x || @P.y<bmin.y || @P.z<bmin.z)removepoint(0,@ptnum) is that what you want to do?
-
the solver is expecting an SDF so you need to use the 2nd output of the collisionsource1 SOP.
-
Here is an example if you're interested. for the lowres sim, I had to change the "color" Enable Solver DOP, it required Alpha, and I didn't want that. for the upres, I just added "Cd" in the gasAdvect. As a bonus, I added a scalar field name "cdl", it's used to store/set the length of Cd on every frame, it keeps the colors visible for much longer. left: div size=0.2, right: div size=0.033 (6x upres) advect_Cd_bunker_001.hiplc
-
the upres solver hasn't been updated for a while, you'll need to add 3 things: - resize the Cd field - source into Cd - advect Cd (inside the upres solver, the advect_density1 node) hope that helps.
-
you can use a sopnet inside DOPs volumemax_in_dops.hipnc
-
there isn't anything in vex to do that directly but you can reference the hscript output value in vex, eg: float maxvalue = chf("maxvalue"); create a spare parameter, then you can enter your hscript expression there: volumemax("/obj/geo/myvolume", 0)
-
hscript volumemin() and volumemax() if you open the Textport, type: exhelp volumemax
-
change the gasmatchfield1 rank to "Vector" instead of "Scalar"
-
you need to remove the '@' symbol vector pdir=point(0,"P",7);

Installing latest Nvidia drivers on Ubuntu
bunker replied to RoaringDog's topic in Operating Systems
I tried so many ways to get my 1080ti to work with Ubuntu 18.04 but no luck (it worked a few months ago), anyone got it to work recently? or any other linux distro actually, I don't mind... found the solution here, in case anyone's interested: https://www.youtube.com/watch?v=GljujCLixzE I got the Drivers Version 430.40 working on Ubuntu 18.04 LTS -
I had the same issue before. you're probably just running out of IDs since it's only a 32 bits integer (2,147,483,647 max) It's going back to zero after that max value. it seems like a lot of particles, but after a few hundred frames it's likely that 2 particles have the same IDs. One solution is to add a secondary integer attribute to extend the range of IDs, you'll need to edit the FLIP solver's part where is ID is generated. hope that makes sense
