Group by Color
# Put a partition SOP
# type this expression on rule color_`rint(@Cd.r*255)`_`rint(@Cd.g*255)`_`rint(@Cd.b*255)`
or choose group by color

# We can point a piece attribute in the end block of the loop.
Smooth jittery animation
Smooth jittery animation
#Take a chop network , append a geometry CHOP refering to the animated mesh
#set the method to "ANIMATED"
#connect a filter node
#To get the smooth values back append a Channel SOP and set it to animated as well and point the filter node inside
For Getting Basic Facing Angle pass

#1.negate the global shading variable "Incidence" and normalize it
#2.dotproduct between normalized N and the above incidence
Or
#Use EdgeFallOff SHOP node
Loopable particle animation
Loopable particle animation
Its a kinda cheat but it works pretty cool
I was really excited to know how to make a particle animation to loop !!! Usually people would do it by offseting the time and do some magic! I was bit confused with that work flow, so I tried to achieve this in some other way and ends up with a cool and simple trick !! I was so much excited when it starts working.!
workflow:
#Make a particle sim
#create the path of the particles with the help of a solver sop and an add node connect points having same id attribute
#Create @u attribute for the curves
#move the points along the curve using primuv method
#use modulo to instantly snap the point to the start of the curve when it reaches the end
#so whenever it goes to end it snap to start so again it will loop.
This will be useful only in low count of particles. But good to know this way of cheating.
Animating Noise
Animating Noise
To animate noise inside VOP, put a 'vector to vector4' node and connect it between the position and the noise,
so that the noise parameters offset and freq will get the fourth dimension which is not a position in space,
we can animate the fourth channel to animate our noise without seeing patch of noise moving over a particular direction.

Set pivot point for packed primitives
Set pivot point for packed primitives
There is only two options to set the pivot when packing the geo one is "centroid" and other is "origin" , but if need the pivot to a custom location.
USE PRIMITIVE INTRINSICS
pivots positions are stored in primitive intrinsic attributes
so we can easily access it NO WORRIES!!!
# put a Point Wrangle store the point position where you want your pivot as an attribute
v@baseP = point(0,"P",1);// here i took point number 1's position as my pivot.
#pack the geo and transfer our new attribute using pack sop
#Put a Primitive Wrangle write these lines to set the pivot
vector baseP = point(0,"baseP",@ptnum); // get the point attrib
setprimintrinsic(0,"pivot",@primnum,baseP,"set"); // apply the point attrb to the packed prim
click on setprimintrinsic to check that vex function
we can set any primitive intrinsic attributes using this function
