Problems emitting from multiple positions stored in an array

[angelous4x]

Hello all
hope some one could help.


i have created an array of positions so i could randomly choose to emit particle from. so i get the data i have set and then plug it into an "select in array", and plug it into the "emit from position" node.

works fine but. once i plug in a "randomize" node into the index or a "module". or anything in to the index of the "select in array". nothing emits. it only works if when nothing is plugged into the index. I feel that it should work with a "randomize" node plugged in.

any reason why the randomize node plugged into the index of the select in array stops the emittion from working? and is there a work around?

Yes, there is a reason why Randomize Value by Range does not work in that ICE tree. Take a look inside the Randomize compound. Hint: ID

Thanks steve Blair


works fine. so simple

i think i understand why it didn't work. it was looking for the point ID to randomize the value per point vs just randomizing the index.

Right, and the point ID did not exist at that point. You just need to use something else as the ID, like maybe NbPoints (except that you are deleting points later on) or maybe even the frame number.
