Metallic Paint Pour - Flake Movement and behaviour Tips?

[dbakewel]

Hello there.
I'm trying to figure out how I could achieve a metallic paint pour like this real world example:-

I should mention that we're currently using Maya 18.3 and Vray 3.6 and PhoenixFD 3.10

my main problem is i haven't figured out where the PhoenixFDtexture would slot in to this material setup to try and simulate it and get the flakes to flow and interact with the liquid.
I'm looking to try and get the paint swirls to behave like the example.

How could i fix my shader to incorporate the flakes in to the pour and flow? Have i even gone about this the right way?

Hey,

In order for the texture to flow with the liquid you will need to transport the uv coordinates as well.

I'm afraid that this would not work with Phoenix 3.

In Phoenix 4 we have implemented the TexUVW channel which allows you transport uv data along with the fluild. You can take a look at how this works in the tutorial here - http://phoenixfd.cgrecord.net/2021/0...th-texuvw.html
The tutorial is for 3ds Max but the same setup would work in Maya as well.

Cheers!

Thanks for the reply Georgi.
I had previously seen the lava flow demo/tutorial, but hadn't figured that it was for PFDv4.
Until we upgrade later in the year, I guess I'll have to put this test off until then.
Thanks again, though.
