Tyflow Motionblur

Hi,

Is there any chance you guys could have a look at tyFlow again? I understand its very difficult to add motionblur to geometry that changes topology. But when the topology is the same it should be able to load and render a tyFlow particle system. Corona hangs on parsing the scene for no apparent reason. Octane is almost just as picky when it comes to changing topology, but it renders these scenes fine. I would prefer to use Corona.

Example TyCache that crashes Corona: Unique Download Link | WeTransfer

Animation begins at frame 750.

I would love for this to be fixed too.

Got the exact same problem here with Corona 6 Daily Build.

@nagboy can you please re-send the scene on wetransfer or host it using our uploader: Chaos

Hi,

Ive uploaded a new file through the link you provided.

I really feel this is a typical example where motionblur should have worked. The tyflow configuration has been tailor made for corona acceptance criteria - no change in topology, still it hangs at “Transforming Vertices”.

  1. All particles are simple spheres.
  2. There are no particles birthed / killed during the entire animation (no change in topology)
  3. Particles are scaled to zero instead of killing them - so they are still in the scene, just infinitely small.
  4. All particles are birthed at the same frame (frame 0) (the animation is reverse direction so they are all actually birthed at frame 500, just playback is in reverse).

Is there any workaround for this, i.e. generating motion blur for TyFlow?

yikes

Guess there are no news… even TyFlow forum says is not “officially supported”… I switched from Vray to Corona and now my motion blurs are gone!!

Let us know any update pleaseeeeee!!

8

A workaround for now is to birth all the particles at once, corona dont have motion blur for particles created spontaneously on the timeline.

9

Yes this does suck. The motion blur issues with Corona are getting tiresome.

10

Don’t ask me how, but in a recent rendered animation I managed to get motion blur working… seemingly without any tricks…

See the example; the book pages are a tyflow object (not tycache or tymesh).

What am I missing here?

Could be a rendering artifact that looks like motion blur(?)

12

Must be pretty beneficial artifact :]

13

lol yeah, super beneficial. I don’t know what’s going on in that setup, but it would be pretty wild to have stumbled upon a workaround for motion blur that shouldn’t exist yet.

14

It’s definitely motion blur, it becomes obvious when I tick the ‘motion blur’/‘geometry’ in the camera settings.

15

If that tyflow is not spawning new particles you can get motion blur.

16

Ya the problem comes from particles being born over a duration of frames. That book scene has all geo spawned at one frame and never changes its count.

17

That would explain it, thanks for clarifying

I am too having problems for this for a long time now. Even if I would love to be able to have motion blur within TyFlow and Corona, at least being able to turn off motion blur on selected objects would help a LOT. Because now, you have to turn of geometry motionblur on everything to even be able to render particle animations, or try to set up the scene so that particles are rendered separately, which none is ideal. This has been bugging me for a long time.

In TyFlow there’s support for Render instances, which is supported by V-ray. Maybe Corona can make support for that, since Corona now is part of ChaosGroup?

19

I agree, it will be great if Corona will support TyFlow motion blur and also, finally, motion blur of topology changing geometry. This is the main things for animation of products, advertising, etc…

We already have multiple issues / feature requests for tyFlow + Corona.
