V-Ray Fur

[psanitra]

I would love to have and option to be convert viewport representation of Vray fur procedural to polylines. Ideally if we can just drop a convert SOP and we`ll get the default 8 knot to 8 points per polyline. That would be amazing, thank you!

I've enabled unpack support for fur node and added "Max. Preview Knots" control.
Nurbs curves will be unpacked so you could convert them to polylines later.
Will be available in the next nightly.

Perfect, will give it a try when the new build is up.

bdancer Tested it, works great.

I would push my luck a bit more here, but would it be possible to inlude UV attribute from the surface it was generated on?or a field to list attributes to pick from surface?
Why i`m asking, is because doing attribute transfer after the conversion does not work great, because individual hairs might be far away from the hair root and will pick wrong uv/color/or what ever i`m transfering. So i have to work that with some for loops, picking hair root, then promoting up etc. Long story short, it would help to have uv transfer directly if found

Hello psanitra , I've added your request as HOU-1799.

Hello again psanitra , I don't know when this will be implemented in VFH , but manage to build a simple setup to sample attributes form mesh to V-Ray Fur unpacked curves. It is based on Entagmas knitting tutorial. Check if this work for you.

[psanitra]

thx, i know how to do that, was just saying i prefer not to. If that can be sampled with your plugin directly, it means less nodes, less work/worry for users. My whole point was - we want to avoid what you just did there

[chakarov]

I manage to shrink the whole setup to just single primitive wrangle which is a lot faster, and it is just two nodes.

On this topic, can you think of any way to make the unpacked hairs render with a taper without building tube geo?

[chakarov]

Hello Dubbie99 , I am not sure if you ask for this kind of solution, but here an example of sampling uvs and color from mesh, and a taper. Be sure V-Ray Hair Properties are assigned at geo node and with Width Mult = 1.

Sorry missed this post Chakarov. Thanks for the sample file!
