Nice! Renders look really clean and crisp.

Thanks Adam! Learned a lot from you throughout the years!

Thanks guys!

3. ### Age on points

Been trying to figure out how to add age attribute on points.
Anyone got an idea how to do this?

4. ### Deforming geometry

Glad you like all my work

Here's my (6 months?) of explorations with Houdini for people who is interested https://www.behance.net/DFMN

AND also a BIG thanks for the odforce community that help me a ton!

5. ### Triangulate (remesh) based on gradient

6 hours ago, acey195 said:

you can give target edge lengths as an attribute in the mesh

See the help file for more information, I don't know the attrib names from the top of my head

Yeah I saw that but I couldnt figure out how to get it to work really. Need to experiment a little more today!

Thanks!

6. ### Triangulate (remesh) based on gradient

Hi peeps!

I'm trying to figure out if its possible to triangulate with either the Remesh SOP or any other way based on a gradient.
So just like the Remesh SOP's visualize size function but with your own gradient. If that makes sense.

Any ideas?

7. ### Move Points

@f1480187 wow!... Thank you so much sir, this is amazing. Gonna try to recreate it in vops so I can understand how it works!

8. ### Move Points

@f1480187 is it possible to give each point a little delay before they start moving again? something like this:

I can just do it by hand, but I also trying to learn get better at houdini so this is very good learning for me!

9. ### Move Points

For vertical line with several points it is as simple as:

```
// Point wrangle.
@P.y += max(0, @Time - @P.y) + @ptnum / 10.0;```

Ask, if you will have problems with actual, more complex setup.

wow thats amazing! Thanks!

10. ### Move Points

I'm trying to figure out how to move lets say point0 90% in Y towards point 1. When it moved 90% then move both point0 and point1 90% in Y to point2.

What im trying to create is theater curtains and I gotten pretty far, but I want to make a lil better.

I drew a picture which might make it easier to understand. You can also check out the file what I got so far, of course I would need to have better settings etc.

Any idea highly appreciated!

11. ### Simulate FEM cloth with GPU?

Is it possible to simulate FEM cloth with GPU?

12. ### Convert Outline Edges to Nurbs

5 hours ago, f1480187 said:

By using Houdini 15.5 new Dissolve. Two ways, actually.

Also, on Houdini <15.5 or instead of Dissolve you could use Divide with Remove Shared Edges turned on, since your edges are geometry border edges.

wow thats awesome! Thanks!

13. ### Convert Outline Edges to Nurbs

Hey guys n gals

Im trying to figure out how to convert my outline edges of a voronoi fracture to nurbs. I got the edges selected but I dont know how to go from there.

Any suggestions?

Thanks!

Check out my file

14. ### Soft bodies help/tips/tutorials

AWESOME, thanks guys!

15. ### Soft bodies help/tips/tutorials

Im still struggling with this.

So what I figured out so far is that you can't just copy a bunch of spheres and then use a tissue object, that will just make the whole thing to one object.
Been trying to find a way to do this and I check the files from the post that Juraj posted and they're all good but none what I saw used FEM.

This is what I got and its clearly not working

https://dl.dropboxusercontent.com/u/10345256/copy_fem_test.hiplc

Not sure if this is hard to do or if its just me.

Any help is appreciated

Thanks!

16. ### Soft bodies help/tips/tutorials

Hi,

also check this tutorial.

As described in tutorial, you can use also wire solver for soft bodys. It should be faster but you may not get volume preservation (not 100 percent sure).

Alse I have seen great example here on forums which uses bullet solver and constraints.

Juraj

Awesome! This cleared a lot up!

17. ### Soft bodies help/tips/tutorials

Hey guys/gals!

Been trying to find a good tutorial or tips on how to use soft bodies in houdini but with no real success.

What I wanna do is quite simple but not sure where to start.

I wanna copy a bunch of sphere and they just fall and bounce around.

Basically this

So if anyone got any good tips or a tutorial on how to do that I would be very happy!

Thanks!

18. ### Random Extrude Distance

Matt you're the man!

Thanks!

Yep, the new polyextrude uses attributes rather than local variables. On the 'local control' tab you'll find toggles to enable attribute overrides for various properties. To randomise the distance, turn on 'zscale', and make sure you have a randomized @zscale attribute on the primitives feeding the extrude.

Attached 2 ways to do this, one with a prim wrangle, the other with an attribute randomize sop.

19. ### Random Extrude Distance

So I'm trying to figure out how to do a random distance on the PolyExtrude but with no luck.

I thought it would be simple with just a rand(\$PR) expression...

I found some old example files and they use that expression but the polyextrude is different so I guess its an older version of the extrude.

Any one that has an idea how to do this in H15?

Cheers!

20. ### Random Effector

Thanks Matt!

I've been going thru most of the files you've been posting here, awesome resources!

Gonna see if I can understand what you've done.

Thanks again

Here you go...

21. ### Random Effector

Hey!

This is my very first post here and as you'd expect I'm fairly new to houdini.

I bet this has been asked a million times on this forum before.

So I'm trying to understand VOPs and how to recreate the random effector from cinema 4d in houdini.

Random Scale, Rotation and Position and be able to control it with noise so you could get movement as well.

If anyone has tips on how to do this or know a good tutorial/tutorials on VOPs

Thanks!
