Controlling Droplet Movement | FLIP Sept. 26, 2025, 5:56 a.m.

Hello everyone,

I’m working on a beer can animation and want to simulate condensation water with FLIP particles. The idea is that most droplets should remain almost static on the surface, while only a few slowly slide down.
What would be a good way to control the individual speed of the particles? Could attributes like mass or stickiness be used for this?

Any technical suggestions would be greatly appreciated!

Motionblur on Nurbs Curves | Solaris July 16, 2025, 2:46 p.m.

I fixed the motionblur node inside now. I changed the Cache Behavior to "Cache Current Frame Only". That works correctly though it causes a hell lot of data for my vram.

Motionblur on Nurbs Curves | Solaris July 15, 2025, 7:05 a.m.

Hello,

I'm working on some threads blending in. This is a preview:

There are still two problems in that shot:
First, the points generated by sweep on the original curves are not consistent. So I have some flickering and gliding effect.
Second, I didn't know a way to render this with correct motionblur.

So I changed the algorithm to having the complete curves right from the start with consistent point numbers. They are not trimmed anymore, the blend-in effect is entirely controlled by pscale now. Also I use Nurbs Curves to have the shapes interpolated automatically. The curves are imported to Solaris correctly. But when I try to add motion blur, the attributes are not updated anymore, neither P nor pscale. However it seems, checking/unchecking "Always Include Frame Sample" on the motionblur node forces a refreshing of the cached attributes.

Do you have an idea how to make it cache correctly on every frame of the animation?
