Colored smoke in 19.5 with redshift
Sepu replied to Alfred_dupont's topic in General Houdini Questions
Merge the Cd field with vdb vector merge node. -
You can use the particle age attribute and divide it by the time increment. i@myattrib = floor(@age/@Timeinc);
-
Grab the bottom of your geo, group it, or blast it then you can ray it onto the collision geometry (the sphere in this case), then use Point Deform which will wrap it into position.
-
if you look at the second screenshot your ramp has a value of zero. Play with it outside of the VOP network.

Difference between vector and 3 floats vector?
Sepu replied to archz2's topic in General Houdini Questions
https://www.sidefx.com/forum/topic/21036/ -
You can do vector h = point(1, "P", @ptnum); f@height = h.y; or with opinput f@height = v@opinput1_P.y;
-
by default, the flip solver has age off so you have to turn it on by checking this box. viscous_flip.hipnc
-
is because the find shortest path is killing the attributes needed by the attrib interpolate so just use the attrib transfer them after the find shortest path node.

you were overcomplicating the setup. Don't need to ctp, etc the path deform takes care of that. Pathdeform.hip

transform Move Object Along Camera's Depth Like Maya's image plane
Sepu replied to Max_Steven's topic in General Houdini Questions
Not sure exactly what you mean, you have a screenshot here showing some track footage and an image plane. You can move the image plane in space with the depth setting in Maya. Is that what you want? moving the image plane in Z? -
Objects deformed on chain SOP in vellum sim
Sepu replied to edversicherung's topic in General Houdini Questions
delete the @pscale attrib coming from vellum -
You can use the emission attrib for that. Or you could scatter pts and use the density attrib and then just emit from those. Different ways to accomplish the same
-
use the Polyexpand instead
-
Do not need anything of that anymore btw. Just use Bifrost Graph and export them as pts from H. It will bring all attributes, etc.

Working fine here .589. Try this package 00_Redshift.json
