Can i import .Uasset files (UE4 assets) into Houdini? (and if yes, how?)
dleonhardt replied to Snappy_Darko's topic in Games
Uassets are just containers. You can unpack them with tools like UE Viewer, granted that those Uassets aren't encrypted. If you are lucky the geometry files inside are just regular FBX. -

How to move points only on Y axis using noise?
dleonhardt replied to carl45456's topic in General Houdini Questions
Click on the 'XYZ' button right of the amplitude parameter and use {0, 1, 0} for the amplitude scale. -
LabsTrees_Displacement_Test_v001_dl.hipnc The 'pos' input on Noise VOPs needs the position to be able to spatially sample the noise, not the normal. Displacing along the normal is usually done by taking a 1D(scalar) value, multiplying it with the normal and then add that product to the current position.

Problems connecting curves with the skin/loft nodes
dleonhardt replied to SnowballWar's topic in Modeling
To avoid this happening with the Skin SOP, you need to make sure that all your curves have the proper vertex order. Reversing the last curve should fix your problem. -

The reason the cubes won't move inside the solver is because the 'Prev_Frame' Dop Import doesn't reference the actual previous frame, like a timeshift with $F-1 would do, it references the output(!) of the solver from the previous frame. Which means that you have to output 'Input_1' and copy the attributes from 'Prev_Frame' in your case. movingobject_dl.hipnc

Solaris: Export USD with USD ROP - material not working for rubbertoy
dleonhardt replied to anicg's topic in Lighting & Rendering
If I had to take a guess it's because the textures for the Rubber Toy are embedded inside the Rubber Toy HDA. So you'd have to export those textures and apply a new material with the proper texture paths, as USD View most likely doesn't understand Houdinis 'op:' syntax. -

My method for calculating if there is a left- or right-hand turn requires a curve, because I am comparing the position and normal direction from the previous and next points. If you want to use particles you need to scatter them after the calculations on the curve like @ryew said. EDIT: Added a couple of lines to the curve calculation so curves with very sharp turns get correct bending ratios. curve_smoke_outwards_dl_v2.hipnc

The only thing the OpInput parameters on the Global Parameter VOP are doing is passing on the "opinput:" string. So to get your spare parameter you just write "opinput:-1" on the parameter that expects the file name.

The reason your boolean is disappearing is because the Polywire SOP in your scene is creating self-intersecting geometry at too many places.

The Volume Mix SOP has the "Blend" Mix Method which does that
