Extract texture map from TyFlow simulation

[jaseemharry]

Hi
I was creating a condensation effect based on this (www.youtube.com/watch?v=wccOSFz-CeU) tutorial. But I want to generate a map based on the movement of particles so that I can use it as a mask for the glossiness map. Is there any way to generate a map based on the movement of particles?. 
Please let me know. Thank you.[url=https://www.youtube.com/watch?v=wccOSFz-CeU][/url]

Ummm... how about this:
(if you're using Vray)

You create light material, (apply to the bottle), and within it's map, you place a Vray distance map, and choose Tyflow (make sure your mesh operator is set to triangle, and uncheck "render only"), or Tycache. Then in the distance map settings make sure you set up it that way, so where the Tyflow "touches" the bottle it's pure white, and on the rest is pure black.
Now, just go to render to texture, but before that, make sure you set io "range" (so it renders animation in the render setup.

Haven't tried above, but in theory, it should work
-------------------
And yeah, you can also directly create mask that way (with distance map) for your glossiness map.
-------------------
If you need something like real "wet maps", meaning that the trail will remain, even the particles are gone, then discard the above and try this:
Make sure your bottle has many (enough) polygons, and add to it Tyselect modifier. In Tyselect go to the mesh mode, and pick your Tyflow.
Enable additive selection, and check out so it bakes it in Vertex colors.
Use vertex colors as a mask in your glossiness map.
