View Full Version : "venom-like" symbiote type effect? like a fluid that consumes something?

imagine a simplified version of the symbiote effect from Spiderman. venom's symbiote, a black dark fluid that "consumes" an object.

in this case.. just imagine a sphere, in the middle of the scene.

from the top, black fluid "pours" onto the sphere, but the fluid sticks to it and slowly cover the entire sphere.

what you're left with is a totally black sphere coated with the fluid.

now, im not actually looking to ANIMATE this, necessarily, but more like produce 3-4 really nice keyframes of this type of effect, so i suppose some sort of animation is "necessary".

assuming i create a sphere.. easy part, hehe... how do i go about creating a fluid type effect like this, one that can stick to my sphere and coat it as it touches it?

and i mean doing this strictly with C4D, i dont have realflow or any external high-price apps.

because of this, is there some clever way to "cheat" this effect, since im just doing keyframes? it still needs to look convincingly enough like a liquid that is slowly engulfing the sphere...

blender fluid (free!) to animated displacement map with suitable shader?

plus I'm pretty sure Blender has a new fluid control option which may well be exactly be what you're after.

You could use TP and metaballs to get something like this: http://www.3danvil.com/tutorials/sploodge.c4d

I did this like 5 years ago with TP and metaballs (like Adam mentions)

I would imagine you could draw a web of splines all over your sphere and using the aixsponza plug "spline on spline" you could grow the web, and put that in a metaball.
If you want something more spindly.


EDIT: WOW--great minds think alike!
(hadnt looked at Adams file till now :) )

If it doesn't need to be an animation, you could also maybe pull off a few convincing stills with Cloth.

I'd use Realflow and have an invisible sphere around the sphere for collision. It would have a hole in the top to pour the liquid in. You're not going to get good results with any other app (maybe Houdini).

i found this on CGsphere
its ALMOST what im talking about (just not "violent" or sticky enough looking)

nevertheless, it says he used 3d studio max for this. but this doesnt look like meta balls or anything. what method do you think is best used for this?

I would guess that he modeled the slime.

Yes, looks modeled. Not a biggie.

1. Duplicate your geometry and make sure the duplicate is selected
2. polygon mode
3. select polygons where slime should NOT be later
4. Structure -> EXTRUDE and make sure CREATE CAPS is selected
5. Select hypernurbs, drop 'outer shell' into hypernurbs
6. tweak till happy.
