Syflex on animated geo

[sant0s]

Hey

I made this algae here and wanna let it decompose:

Nudity warning: [ Show ]

Nice ICE job I thought.
So a kollega gave me a scene where he animated the plant with a lattice.
Problem now is, that I cannot add any simulation on top.

I had that problem once, but dunno how I solved it. To long ago ^^
Is there a way to add syflex on an object thats animated with a lattice?
I wanna add some simulated peel effect/syflex and let parts of the leaf sink to the ground, but the plant itself needs to bend in the same time.

Thx alot!

Have you tried putting the lattice deform -after- the simulation? (in the "Post-Simulation" stack)

PS: AAH!! A completely nude Algea!! Good thing there was that nudity warning

oh man, dude... thank you so much!
I was moving everything in the stack - but not the lattice...

hehheh, yea - I though that green, slimy, salty could make 3d guys grrr , so better put a warning ;)

It's actually pretty neat, light transmission looks good,
yet perhaps it could use less specular reflection? (if any at all especially under water)

For light at glancing angles if you multiply an illuminatiuon shader (using diffuse only)
with an (perhaps gamma-ed or exponent down) incidence
(getting exponentially instead of linearly lighter towards edges)

and then screen or add the incidence multiplied shading result to your current shading,
it should more closely reproduce how "speculars" look & behave undewater


For the subsurface light tranmission which looks good but peraps slightly flat,
you could re-use the gamma-ed incidence alone except inverted to modulate subsurface light transmission

It would reproduce what refraction of the transmitted light would look like, while accentuating the impression of thickness

Nice job though! and well balanced, looks dreamy

Wow, great infos here!
Will try that tomorrow - right now I get the syflex peeling done for a first night run. amazing ICE
I still dont get over it, that SI is kinda "dead"...!

But nice to get more infos than expected, thanks for that!
Ill give an update on that.

[FXDude]

No prob! cant wait to see it!

good morning

just realized, that I get another problem now.

The Lattice is doing a good job and also syflex is working.
But the syflex get simulated, like there is no Lattice - means, the gravity is following the bended lattice...
Just uploading a video to show the problem, vimeo needs stome time to converte ^^

The lattice is being applied after syflex, so that's bound to happen. It fell down , then You warped "down" to be across and down.
Syflex has no knowledge of what happens after its applied.
If you want syflex to be affected by things in the scene then you'll have to use things like mimic, pin and your ingenuity.
I often use mimic to affect simulations.

[sant0s]

hey pooby - will try that, thx!

[FXDude]

Could you also perhaps have an independent cloud to emit flake particles or "falling leaves" (perhaps progressively with states) from the deformed geo, then only affected by it's own forces?

Cause even if syflex would keep underlying deformation animations, wouldn't point positions (along with gravity) also be bound to the lattice deformation field?

cheers,

[sant0s]

hey dude

actually my goal is, to get some kinda decaying - similar to that fantastic animation here: https://www.youtube.com/watch?v=w9A1eQIWc-c

I just started to work it out with a mix of hand animation and ICE Shape defomartion like here: http://caffeineabuse.blogspot.pt/2012/0 ... image.html

The problem with syflex and mimic/pin is, that the plant has not so less points - and controlling that with another geo drives me crazy

So for now I am deform, delete polyons and emit waste/bubbles by an growing weight map, that seems do to the trick and I have much more control!
And its not having problems with lattice.

Ah, before I forget, maybe someone has an answer: The biggest problem with syflex I have is, that the leafes are not connected to the stem. Its one geometry, but its like merged without the points are merged (dunno how to say that ^^ http://abload.de/img/plant0flwk.jpg).
So when simulated with syflex, the leafs just fall down and that looks shitty... Is there a way to realy connect the leafs to the steam? I started by hand, but that realy depressed me ^^
I made that plant with forester, btw.

Have you tried booleans to merge the meshes? there's also Oleg's implosiaFX (for shattering) that contains a reliable and fast ICE boolean compound.
