UV transfer between totally different meshes
bunker replied to miccetro's topic in General Houdini Questions
I had a look at your file. The UVs are still there after the voronoi, in case you didn't notice. just plug a uvquickshade node... -
UV transfer between totally different meshes
bunker replied to miccetro's topic in General Houdini Questions
you can try with xyzdist and primuv: // wrangle (run on vertex) // copy closest UVs // second input is the original geo int prim; vector uv; float d = xyzdist(1,@P,prim,uv); v@uv=primuv(1,"uv",prim,uv); -
maybe this? assuming you're on Ubuntu: https://itsfoss.com/manage-startup-applications-ubuntu/
-
you can create a subnet or an otl and add an input to that.

Linux access problems - "ModuleNotFoundError: No module named 'viewerstate'"
bunker replied to Memo's topic in Operating Systems
you should read about file permissions: https://phoenixnap.com/kb/linux-file-permissions TLDR, you can add the rights to execute "hscript" sudo chmod +x /opt/hfs18.5/bin/hscript ... and run this one-liner: cd /opt/hfs18.5; source houdini_setup; hscript does that solve the issue? -

VEX is exactly like C, variables are declared once only. You only need "@" when importing or exporting attributes (in this case point attributes) But if you call an attribute inside VEX, then you need to tell VEX how to interpret its type. hence the v@ or f@ in front for example: vector a,b,c; a= {1,0,0}; b = {0,1,0}; c = a+b; // export c as an attribute named d v@d = c; You should read this: https://www.sidefx.com/docs/houdini/vex/lang.html

windtunnelmask.hip
-
if you really want to use the wind tunnel direction, you could try cancelling the wind velocity inside the chimney for example.
-
wind tunnel direction is on the smoke object. it sets the velocity on the boundary of the vel field. so no, you cannot mask that.
-
you can still have zero turbulence outside of your range, if you set the values at zero at each end of the ramp: if you need more control, you can change the range from 0 to 100 for example.
-
The control range is used to remap 25-50 to 1-0. that's because ramps use values from 0-1 as input. The values below 25 will get the amount of turbulence you have in your ramp at 0 (left side) and values above 50 are mapped to the ramp value at 1 (right side) GasTurbulence DOP is an OTL, you can go inside and see exactly what's going on. Hope that makes sense

Search for advect particles houdini on youtube, there are tons of tutorials.
-
Save your sim to disk and use the frame 100 as initial frame for to another bullet sim with less substeps. done.
