Cool tuto ! It's exactly what I needed ! 👍👍

[@vvzen]

Great tutorial, as always! My 2 cents: instead of using a switch node, I’ve found out that you can just add an expression to the “Emission” > “RBD Bullet Emit” parameter in the rbdconfigure. When that parameter is 1, it will emit, otherwise it won’t. So you can set it to something like @Frame % 10 == 1. (tested in H18.0.499) (of course this only works if you use the rbdconfigure, not if you use just the rbdmaterialfracture)

i tried your tip, but idk why every 10th frame the emission start and disappear right away, it least 1 frame any suggestion?

[@vvzen]

@@andreanvfx3901 hi ! IIRC, that is exactly the snippet is doing, setting that parameter to 1 will cause it to emit, which is what the modulo operator (% == 10) does here. What do you need to achieve?

@@vvzen hi Valerio, im trying to replicate the 'inside bellatrix vault horcrux FX' which each rigid object emit 5 or more obj when hitted, any clue? I round a recursive fracturing tuts but i dont think i can achieve the result i want with that

[@andreanvfx3901]

i maybe express myself wrong, i know that the modulo trigger the emission every 10 frame 1 times, but after the trigger the emitted obj disappear instead of staying live

Great tutorail, how do i add random rotation to the emitted fractured objects ? Cubes for example.

Thanks for this great tut.How to make it in dopnet?

[@MrAvoronov]

Tnx! How I can stop emit simulation?

[@adityaambekar2610]

How You Made That Bowl Object.. Explain me plz

[@MarioSundays]

Tks for this tut guys. What if I want to emit RDB to fill a box? Imagine I want to fill a box with small Granola cereals.

Try Vellum grains for this.
