Create Extrusion Along Strands V2

[Mathaeus]

I've fixed this flipping by using 'From custom vector' and plugging YourPointcloud.StrandNrm into UpVector slot. afaik strandnrm was set by 'Knit Strand Prepare MT_Extrusion' compound in my case...

yeah, whenever strand is parallel with NURBS surface, it seems somehow logical to use point normal as an up vector. Nice that these compounds still works, they are 2 years old

I will try this, thx for the tricks

[Ramon]

Thanks for compound!
1) How can get a flat mesh from strands(for grass), when NB subdivision is 1 or 2 I get a flat mesh but with duplicate edges
2) Don`t understand how get e textute projection, Auto UV not give a clusters with projection!
Thanks in advance!

i looked at your examples but i just don't understand how you achieved the tapering on the extruded mesh... ??? ... (question related to first post)


EDIT: got it! it's in the modelling stack of simulation_pointcloud.
oh yeah, that's so cool!

1) in the example he plugs a curve circle as a custum shape into the extrude compound. seems to work, although i had no luck with that...
2) on your polymesh connect "this.StrandToMesh_Texture_Projection" to "this.cls.Texture_Coordinates_AUTO.Texture_Projection.UVWs" (or whatever projection you have. you need to have one already and then overwrite the UVWs). don't know if this is the official way, but it works for me...

Is it possible to create interactive extrusion with % of strand length?

Sorry to revive an old thread, I have a problem may be someone else has also experienced. Maybe not but it's worth a stab.

I have meshed some dynamic strands using the Generate Extrusion along strand. All good works fine. I then add a weightmap filter to the strands and the extrusion ceases to work. Has anyone else got around this problem? If there's no solution I'll stop using weightmaps and find another way.

If anyone knows anything about this, even to just tell me there is no solution I will be very gratefull.

Fingers crossed.

And the solution? (of sorts)

Just use Polynoids deform by strand compound instead.

Onwards!

Hi, sorry if I bother you but... how do you connect those attributes? In the ICE tree or whatelse? I can't get the texture projection...

Been playing with this great compound today. How did you get the taper in the strands from the first picture in the thread? Is there way to use an fCurve to define the shape along the length of the extrusions?

[druitre]

How did you get the taper in the strands from the first picture in the thread?

Look in the example Kristinka scene in the first post, and then in the simulation pointcloud's ICEtree. It has a calculate strand ratios + fcurve that's doing the tapering.

Can someone go into some detail on how the automatic UV's work? It doesn't seem so automatic.
