Correct way to smooth particles?

[GreenDK]

Hi all.

Just goofing around and making a Fall setting with some leaves.
I wanna add thickness and smooth out the leaves.
But what is the correct way to achieve this?

I see the Turbosmooth gets added in viewport, but it does not affect the render?

Using 3DS Max 2025 and Arnold render.

Change mesh operator to triangle mesh, turn off "render only" and you should be able to see turbosmooth in render.

Still as jagged as my ex-wife teeth :/

Try a proper render instead of ActiveShade maybe?

I tried that too.
No same problem.

I see the leaf getting smoother in the viewport, but the render does not pick up in it, for some reason.

The file is here if you wanna look?

Always save max files in earlies max version you can, so more people can access and help you.
I can not open it with my max 24.

We don't all have latest max release with latest patch.

Affirmative!

Try Meshsmooth instead of Turbosmooth.

[d4rk3lf]

hmm.. indeed it won't work
I first switched to production rendering mode (from active shade), and I gave it default physical material.

Then, of course mesh operator I switched to triangle, render off... and whatever modifier I added, it just ignored modifiers (both turbo smooth and mesh smooth, I even tried adding edit mesh bellow meshsmooth), and it just rendered raw particles (it ignored modifiers)
I haven't rendered in Arnold in years... so I might miss something in it's options.

However it works if I use Tymesher in combined mesh mode, and hide TyFlow.

Same problem, I tried that

Thank you for your time, dark3lf.
You get the same experiance as me then.
I will remember this workaround. (I guess texturing the leaves will be different?)

Maybe I should mention the problem in Autodesk forum?
Seems like an Arnold Render problem.

Ps. When I use tyMesher combined mesh, like in your screenshot, the particles dissapear.

[tyFlow]

Oh...Arnold. It's possible Arnold is forcing tyFlow's particle interface and rendering as instances, regardless of whether you have a modifier on top or not.

Try this:

Use a tyMesher in "combined mesh" mode and input the tyFlow object. Then put the Turbo/meshsmooth on the tyMesher and render that instead.

[GreenDK]

Combined mesh makes particles dissapear for me.

For anyone interested I used a simple solution to bypass the problem.
Since I just wanna make a single frame, I used Tools - Snapshot and applied Turbosmooth to the mesh.

Still an annoying problem tho

[tyFlow]

Oh, it's cloth...I missed that.

When using tyMesher you'll need to turn the particle interface off in the tyMesher settings or else it won't generate the mesh (because the particles have no mesh and a cloth mesh isn't a particle).

aah, that works.
Thank you
