how does pBounce work??

Hi,

Im trying to make the particles bounce to an image plane in a 90 degree angle but everytime i do put the pBounce the particles just tresspass the image plane


Where do i have to connect the pBounce to in other for it to work??

thank you and have a nice day :)

Basically you have to make a region in the pBounce that coincides with your image plane.

Can you post the comp you have now? That makes it easier to troubleshoot.

Here is what i got so far in the workflow

you may notice that i didn't put the p bounce in it because it will not work, but i also guess that i may have something wrong during what i got so far

you may notice i didn't put the pbounce and its because i can't connect it unless is connected in between the emitter and render particles and it still does not work

I FINALLY ACHIEVED IT

it worked with a Shape 3D> Plane

if the pbounce region is defined as "Mesh" it works perfectly

but when i tried to use a Background Image plane 3D it would not work...it just trespass it

i guess that it must be defined as something else but i don't know what it is??


also the shape 3D must be linked to the pbounce otherwise it doens't work


(WHAT I POSTED WAS KINDA OBVIOUS TO SOME, BUT FOR NOOBIES LIKE ME I RATHER POINT IT OUT ANYWAYS I JUST WANT TO HELP TO :D )

Edwin, one way to post your comps that is really useful as well is by selecting all your nodes, pressing CTRL+C and then going into this forum, click the 'code' button and then pressing CTRL+V.
This way we can get a working copy of the comp you're working on, so we can see more clearly what it is you're doing. This is more useful than screenshots most of the time.

What do you mean by this? An Image Plane 3D is basically the same as a shape->plane, so I don't know why the results should be different.

Hi Sander,


Thanks for letting me know about the copy and paste, like i said i am new here so i'm still figuring out how everything works :)


about the image plane 3D----> yeah i still don't know if i did something wrong in the particles or something

but it works easier with a Shape 3D> Plane

than a BG> Image plane 3D

but whatever works i guess :)

Edwin,

This is the way you copy and paste from the forum:



I hope it helps.
