(SOLVED) Flickering hair in animation Tweet

[Whispermode]

Hello!

I think this is more of a Blender thing than specific to Octane...

I have a head with some hair that's been combed/styled. When I animate the head, the hair flickers at a fast rate.

It's not a texture thing from what I can see, but looks like the hair is changing position/shape per frame.

Anyone seen this before and know a solution?

Thanks in advance.

Fixed - I had a turbulence field hidden in the scene.

There was a little more to it as well.

In Octane Hair Settings, I had the 'Tip thickness' set to '0'. This was causing shimmering/fireflies.

I changed it to 0.0002 and it's now fine.

Also... it turns out you can't have hair dynamics on a mesh that is shaded smooth (?) - it has to be flat shaded or the simulation breaks. You can then smooth shade after it's baked.

From looking around the web, seems like this has been going on since 2.8 and persists to 2.91. Crazy.
