View Full Version : Multiplying two arrayMapper outValuePPs?

Hi there,

is there any way to multiply the outValuePPs of two arrayMapper nodes?

Following problem:
With a ramp and an arrayMapper I scale the particles radiusPP over time. That is fine!
With another texture and arryMapper which gets the parentU and parentV values of the particleShape I give the particles a basic scale value, so where it is darker particles stay smaller - where it is lighter particles get bigger.
Both methods work fine for themselves, but I would like to be able to mutiply their outValuePPs! As these values are doubleArrays you can not use a node like multipyDivide!
Is there any other way to do this or has some genius maybe wrote a custom node for this??

Thanks a lot!

You can multiply them in the particle expression, why do you need to do it outside, when it's going to be used in the expression anyway?

Hey Azrail,

you are totaly right. I just solved it by doing it in the expression! Thank you!
