Pop grain parameters advice ("bound effect")

Recommended Posts

Hi everyone,

 

I'm student in french school, and for my last year project I have to do snow. And more precisely a huge bloc falling to the floor.

I need a lot of particle because for the production need I decided to convert it in vdb and so to polygon, so I need detail.

 

My question is, What parameter should I modify to avoid the "bound" effect. My simulation  flatten on the impact and take back volume.

 

I used the shock scaling power and I played with Scale Kinetic and Static threshold but I don't really understand how this params works.

 

Can you help me with that.

 

Thank you a lot.

hi moustik :)

 

m studying Grain as well, and saw your files.

 

1. But there are lot of .abc files which you havent supplied.

2. Also, what you mean by "bound" effect ?

Oh yeah i forgot the abc file sorry

 

In the playblast you can see, just during the impact the particles compress themselves and little after they recover volume. 

 

I'm not at work today but I'll send abc and obj files this evening.

 

Thx Sultan :)

Hi moustik :)

 

i've noticed that if you turn off or reduce value of "Mass-Shock Scaling" option in POPGrains.. then you could reduce the bouncy effect you were getting.

Let me know if this helps.
