    Hi, there is this project im starting to work on, it would require creating an emitter of particles (object particles) and upon collision of these particles with the Ground (floor object in this case) i would like it to spawn/create/build an object (pyramid shape in this case) in the spot of the collision. I am quite a newbie to the nodes workflow so hence my post here, would there be any kind soul to help me with my task? Ill add a screenshot my current state of the nodes along with my object list. There is a bunch of unused stuff in there (i was really trying to make it work on my own but my success really is not in my reach) Thank you all in advance!!

    Hi Jakub,

    If what is required, as I understand it, is to make the particles after colliding with the floor spread out in the form of a pyramid in the spot of the collision, you can create a pyramid at the level of the point of collision, then apply collision to it, and then make the pyramid hidden so that the particles collide with the floor, then re-collide with the surfaces of the hidden pyramid so you will get the effect that you are looking for.

    Please correct me if your requirement is something else, and then I would like you to post the file here so I can look at it more closely.

    I hope this helps you.

    Hi! Thank you for the quick reply, Im also sorry for not giving out clear information. The whole idea is to create an interactive scene in which there is: A mushroom with a spore emitter, when the emitted spores touch the floor/ground, a new mushroom grows in the site of the collision, eventually emitting its own spores. Now im not sure whether to use a cloner object or if there is some other way. Im a very beginner level in Nodes so i ted to get lost. Do you think i could further contact you in some sort of a Direct messaging? as not to spam the forums here 😀

    once again thank you for your assistance! it is very greatly appreciated

    PS.: the c4d file didnt save a lot of the work i did, it is very bare

    PSS.: all the stuff with the pyramid is meant as a placeholder as to do the nodes first and then to model the objects themselves

    edit:// the nodes are under the geometry modifier group

    You are welcome, Jakub! Until now, I have not been able to figure out your project idea. I hope you can attach an illustration or something similar. You can also send the file to my email if you don’t want to post the file here.

    Thanks.
