The first half of this year is shot, the second half of the year will be like waking up out of deep sleep.

I'm advecting the particles by a volume but the problem is the particles are not sticking to the geometry as they were with the RaySOP. The points are hovering over the geometry, how can this be fixed ?

I figured it out

I'm importing the hit attribute and that seems to do the Job.

Another way to put it is this; How can I create an attribute for the Ray SOP which will project those points which the attribute has applied to the target geometry based on an attribute on the geometry ? haspointattrib() may be what I need for the geometry.

How can I delete points where there is not a float point attribute. For example, I created a float point attribute on the geometry and where that attribute doesn't exist on the geometry the points \ particles are deleted; or better yet, using the raysop, ray cast particles only where a float point attribute exists on the geometry when the particles go outside of this attribute on the geometry, the particles are deleted ?

I'm having a problem, particles are emitting from both my scattered points and a cube; how can I split the two meshes so I can have the particles emit only from the scattered points ?

How do I delete using one of the hit attributes the particles in this case which are ray cast on a surface and that surface is planer (flat) and only those particles which are on a planer surface, if the surface is not planer the particles remain ?

How can I run an expression on the group rename sop that runs over a parameter within the sop ?

I have it figured out, I had to make some adjustments to the ray casting.

@Librarian Except when I attempt to use a Ray sop, along with a point sop, the point doesn't cast onto the attribute from your scene ? @anim Similar issue, I'm getting values using the measure sop, set to gradient; but, the ray sop doesn't case what I want to the geometry in this case for example, a point ?

How do I create a direction vector attribute from color (Cd.r) ?

If anyone has any suggestions, I created an integer attribute and whether it be the Intersect vop or the Ray SOP so the points cast only on the integer attribute, rather then a vector attribute. I've tried binding an integer attribute and using that in an attribute vop but it doesn't cast ?

That isn't working as I want. I give the vector attribute direction but the points are not casting to that attribute.
