Top Tip Tuesday! - xpCollisions

In the second episode of Top Tip Tuesday we'll show you how to set up particle to particle collisions inside of X-Particles.
We'll show you how to use xpConstraints and xpPPCollisions for simple, fast collisions. We'll then guide you through setting up xpBullet for more sophisticated collisions.

great video, please keep these coming. been using XP for 8+ years now, and still learned from this quick tip. ty

[@salraz_mg]

Very Helpful, keep posting such informative videos, Thanks

Can I use the bullet system with Particles as custom objects/geometry?

[@ArgoBeats]

+1

[@IIIusescrtIII]

+1

[@holgi3115]

Yep, i did) But it'll be really hard for your pc, if you have a large number of particles...

[@ArgoBeats]

@@holgi3115 How did you do? With a xpGenerator?

[@iiDiiOZ]

@@holgi3115 Yeah, I can imagine. Thinking more of the possibility, even with just around 50-100 particles

[@cr0ucherrr]

Any news on when will be new update of content repository?

[@JosephWraith]

Awesome!

[@helalsstudio1843]

Excellent! I have a problem my x-particles colliding objects very far from the surface, what settings should I need to change, so particles are colliding close to the surface. Please advise me, thank you.

[@animatex]

Great information, that collision questions come across often! But what do i do with f.e. Sand particles. Lets say 500k particles consisting of 5 irregular particle shapes? Its too heavy for bullet from what i know.

[@INSYDIUMLTD]

You would either have to use the particle display objects for collisions like Bob has done, and use an xpGenerator or instances for the custom geometry onto the particles. Or you could use the generated geometry for the collisions, by adding the bullet collider tag to the xpGenerator, this will give collisions accurate to the geometry but at 500k particles it will be very heavy. If you have more questions or need more help, please head to our Discord server here: discord.com/invite/X2zYY7qEyr -Thanks

[@ariaperdana24]

for things like sand how about just using the sph fluid solver? Should be much helpful than depending on bullet or even particle collision.

hi bob. thanks for the tip. I have off the topic question but i think i am not the only one that has headache .. well i have cached emitter and i want to emit particles from it. the only "laggy/lame" work around it was via xp trail .. is that possible at all. many thanks.

[@INSYDIUMLTD]

Hi, Could you please post this question to our Discord Server? discord.com/invite/X2zYY7qEyr Thanks

[@vladan.Poison]

@@INSYDIUMLTDJust posted it on discord. hope there is a solution .. thanks bob.

[@doom9344]

Let the ship make waves and bubbles like Houdini !!!!

[@daskydesign846]

All very nice but........ the cache still doesn't work with Bullet or am I wrong?

[@zoYoo-fz1xc]

hello! Why can't my X particle recognize nexus and use GPU emulation

Hi, Could you please send a message to Technical Support here: insydium.ltd/support-login/ They'll be able to help you with this. Please give them as much detail as possible to speed up the process. -Thanks

who had installed insydium bridge to cinema 4d 2023.1.2 version?

[@simontrickfilmer]

is there bridge for that?

[@proma8]

Amazing collider but... for some reason it does not collide with the floor... at first it does and eventually all particles are falling through.

[@INSYDIUMLTD]

Hi, the issue you describe is usually solved by changing the scene scale and/or increasing substeps. However, it's difficult to say without looking at your scene file. Could you please head over to our Discord Server to ask the question and attach the scene file. We'll take a look for you. discord.com/invite/X2zYY7qEyr -Thanks

[@proma8]

Thanks, I have changed the scene scale and it solved the problem.@@INSYDIUMLTD
