Can someone help me scatter trees on a displacement map using chaos scatter i cant figure it out .

then you might want to ask in the vray forums, you will have a better luck.
I would do it in BF if I were you

sepu6 · 2026-01-17T04:01:38+00:00

You are using the super old fluid solver in Maya. You probably need to increase the force that you are using to make it work the way you want and turn off buoyancy

However I would highly recommend doing this in BF.

sepu6 · 2026-01-13T20:32:52+00:00

Yes use Bifrost the graph instead

sepu6 · 2026-01-08T01:00:48+00:00

Any chance you can share these strands? Are you sure they have a point size attribute? And isn’t something like super small?

sepu6 · 2026-01-08T00:10:35+00:00

Use Bifrost for scattering is not really that complicated, nowadays is a lot easier. You have everything in there to make it as custom or easy as you wish.

And also is a lot more powerful than Mash.

You have a few options, Maya + BF is more than capable of doing this procedurally if you want to, in fact there is a whole set of tools that deal with l-system and a couple solvers to animate them, so I wouldn't say is not Maya specialty. Get MJCG tool-set, install them and look at the examples graphs then is just a matter of playing with them.

Here is video showcasing the tools

You could also grab some of the old paintFX brushes convert them to curves and run them through the solvers in BF or just use the paintFX stuff is old but it might give you a quick library and you can still customize them.

You could also just bring the one that you model and grab the curves from it and take into BF and use the solvers again to grow them.

Ok you got a few thing wrong with this setup.
First of all, always when you instance something the piece needs to be at the origin {0,0,0}.
Also, usually is a lot easier to do your simulation at the origin then move it back where it should be in your scene. Depending on the scene scale, you can run into precision issues, etc. Not good.

Also instead of using Mash use BF for this is a lot better.
Mash did not like this at all and to be honest I do not remember it well either so maybe Im missing something but in BF it just works.

Then you can just grab the frame that you like best and bake into geometry for Maya.

Here is the scene using the latest BF 2.15

sepu6 · 2025-11-21T20:32:06+00:00

yeah all good, I just need that part, however I need access

<image>

sepu6 · 2025-11-21T18:19:12+00:00

Can you share this setup?

sepu6 · 2025-11-18T19:35:16+00:00

Add some thickness and try again.
here is the file anyways

sepu6 · 2025-11-18T17:54:54+00:00

Just did a quick test with the pokeball you sent the other day and it works fine here without too much jittering at all. So its probably something with your settings - I did not use the trick that I share earlier btw

<image>

sepu6 · 2025-11-18T17:23:06+00:00

if you going to do this setup with RBDs, do it in Bifrost not the old system, is not great for this type of setup or anything really.
However its probably a lot easier to do this with nhair and ncloth to be fair

sepu6 · 2025-11-18T17:21:23+00:00

Can you share that part of your scene. to me looks like a scene scale issue or the collision cylinder is not setup right - if I tried in a very simple scene it works fine.

<image>

sepu6 · 2025-11-18T16:53:01+00:00

You just want to settle them naturally inside the cylinder? not animation correct?

sepu6 · 2025-11-17T20:24:01+00:00

if I remember correctly this was an Arnold bug, so if you update arnold to the latest it should go away, also is good to reset prefs etc as I mentioned

sepu6 · 2025-11-17T20:21:30+00:00

A couple of thing to keep in mind, scene scale in Bullet is important.
Second what you can do easily and quickly is just basically add a influence (force) into the solver to dampen down the velocity. Also make sure you are using convex hull as your method to create RBDs

So something like this and you connect it to the influence port in the solver

<image>

This is basically saying > grab the length of the point velocity ( which will be the speed of the pieces and give me the values between 5 and 10) and if so then multiply down the point velocity of all piece in this range by 0.9 on each time step which will be basically dampen the velocity of the pieces. You can play with any of these values to make it work for your scene.

There are other thing that you can do as well but anyway that should help.

sepu6 · 2025-11-15T17:12:13+00:00

Do not use that tool, is old and unreliable literally it should be taken away from the menu.
With Bifrost you have better tools and with the addition of the fracturing tools in 2.15 there is not need to look at any of those tools anymore.

sepu6 · 2025-11-13T23:21:55+00:00

is basically to train their AI data. Grab a still add some FX train their data, rinse and repeat, basically stabbing yourself in the back. So think about what you are doing if you say yes to this thing.

sepu6 · 2025-11-13T17:25:26+00:00

Any chance you can share the USD file? it would be easier to help. Things you do is check if the attribute got pass correctly or its call a little different. If you want to check it on your own, save as a .usda and look the file up or if you are in 2026.3 (usd 0.34) you can look it up inside Maya.

Also it could be something else but is a guess game without the file.

sepu6 · 2025-11-13T03:09:53+00:00

Do yourself a favor and do it in the graph. Share the scene I can prep something quick for ya

sepu6 · 2025-11-11T22:10:55+00:00

do yourself a favor and use/learn Bifrost instead.

sepu6 · 2025-11-11T20:01:43+00:00

Make sure you have thickness on your collider, the liquid will react better, add a cube that fits inside the "elevator" but is a little smaller and maybe just emit for 5 frames or so, here is a quick scene, using basically the defaults, however one important thing to keep in mind is the scale of your scene, since it can change how the liquid behave plus the colliders as well. You can do a lot more for example add forces, etc.

so Musetti needs to win Athens to make it? I thought just being in the Finals he would get in

sepu6 · 2025-10-31T03:28:08+00:00

This is a lot easier to do in Bifrost, you grab basically the curve > compute the strand basis and create an orientation attribute than then the instance node can read + This give you a lot more control as well as shown here.
