Technical Discussion » render frames backward from end to start

Hey demonsd_miles17,

no that is not possible. Why do you want to do that? Each image gets a name assigned based on its frame in the timeline. So if you render backward the sequence would always play forward in any editor. If you want to reverse an animation, do it on the Geometry level via a timeshift node or with the rendered images in Post-processing.

Cheers
CYTE

Damn,
Anyway thanks for the reply. I don't need to reverse the animation.

I want to render the same scene with 2 different machines in order to speed up the process.
The first one rendering in a normal way and a second one rendering backward.
Then i will stop both of them once they meet each other halfway at the same frame.

Hi guys
Someone know if is possible to render frames in a reverse order (with Redshift)?
From end to start, goin backward.

Thank you.

Hi Guys.
Maybe this is a stupid question but i was thinking about it recently.
Wich file load faster from the file loader?

I have an extremely heavy file with just a couple of attributes (Cd and uv) and i am trying to optimize the scene with a faster file format.
Thank you.

You can still use Fuse for this, and uncheck Fuse Snapped Points, which will effectively just transform them.
damn buddy, thank you !

Hi guys
I have a problem that i think can be easely solved with vex, but unfortunatelly i'm not an expert on it.

I have a curve and i want to copy the last point position (150) on a different target point position (149) without fusing the 2 point.
Point simply should have the same position but have to live separately.

Somoen can help me?

Thanks

Hi all.
I have a switch node with 3 inputs and i would like to switch the input evry 140 frame.

0-140 input 0
140-280 input 1
280-420 input 2

How can i achieve that?

HI guys.
I'm trying to create an uniform nurbs curve started by labs spiral that will be used as camera path for a looped animation.

The issue is the start/end point at the bottom that is not connected and fused and as result the start/end of the animation is not working properly.
Someone knows a way how to solve this problem?
Thank you.

hip file and screen attached
please ignore multiple edits that works for shaping the spline.

Technical Discussion » assign different stifness in a vellum simulated object

Hi all.
I'm trying to figure out how to do an apparently very easy task in a vellum sim.

Basically i would like to assign 2 different stifness in the same objebect, driven by a color.
The object should be soft and hard at the same time, but in different painted area.
i've attached a screenshot.
The red part should be hard (let's say as a wood stick) and the white one soft, as a jelly.

Any help how to solve this?

Thank you.

Hi guys,
i'm trying to create a vellum sim with an object that is changing topology over time.
Do you think is possible?

The object is growing and expanding with a solver, and i would like to simulate it in a vellum sim.

ok, so
i ended up with this and it's working for my purpose.

If anyone have a better solution i will be really greateful.
Maybe for fixing the smal gab between the 2 mesh.
But probably the issue is due to the subdivision level of the first meshes

More the first mesh is detailed, less will be noticeble the gap and the issue.

Thanks

Hi guys.
Hi have 2 different objects, each of them with its own uv.

I would like to convert them in VDB, fuse them with a combine and than convert back in a single mesh.
Now the problem are the uvs…

Is it possible to combine them and obtain a single new uv for the new geometry?

Thank you

I have an easy smoke simulation located really close to a wall/surface.
I would like the smoke will be attracted by the surface, in order to let the smoke “slide” along it.
Is this possible ?

I attached an example file

I prefer to set copy stamp attributes on the points/particles themselves and reference that in the copy SOP, it's more controllable and predictable. Also, a lot of the erratic motion you're getting is coming from the transforms you have on your copy geo, but I'm not sure what you're after. The enclosed file is how I would go about it, I hope it's helpful


It works !!!
Thank you so much Andy !

Hi guys,
I'm trying to copy stamp a bunch of different object on points created by a particle simulation.
Unfortunatelly the particles dies during the simulation, and this cause a change in the particles number.
The result is a glitchy and randomic change in the object copied on the particles.

I know that probably the solution is the use of the @id attribute, but i can't really figure out how to use it in this situation, inside a copy stamp.

I attached a .hip file explaining my problem.

thanks in advice for any help

Hi guys,
I'm recently stucked into this problem… i can't really figure out a solution.

I'm trying to create UVs on an animated geometry, creted by a vdb convert node.
My setup is something like this.

- i create an animation with vellum hair (i need these hairs to be the source of my vdb polygon)
- vdb from particles on that hairs
- vdb convert into polygon

I atatched a jpg

Obviously, every frame the polycount change and also the UV. Results: the entire UV for the animated geo is a mess.

I guess i should create the uv on the hairs, or something like this, before the animation starts… am i right?

If someone could show me a solution i'll be really greatefull.

Thaks

Hi guys,
Hi have a cached simple growing geo done with a solver.
Let's suppose a sphere…
It's possible to animate it with the vellum solver over time?

I would like my geo grow and at the same time simulate with vellum tetrahedral for collision with other objects.
When i start the sim the vellum solver animate only the first frame of my geo and then stops.

Thanks in advice

It's possible to break or fracture an object simulated with the new vellum feature “vellum tetrahedral softbody” as the FEM “fractured solid object”?
I tried with the method “edge fracture” + “vellum weld” but it seams doesn't work.

Thank you in advance !
