Lets say I have Micheal 4 in a space ship reconnaisance mission in space then he gets dismembered by lasers, blown out of the cockpit and DIES.

He is wearing a very cool marketplace skin texture that makes him look so alive but now he is dead, how can I tweak it to make it look like he had died recently? Maybe like a ghastly gray/white looking complexion?

I would imagine that floating in the vacuum of space would affect things - who knows.

On earth apparently the color is green, at least according to:

Unfortunately now, thanks to google, I'll probably never be able to get the thought of the "song" by the "band" annibal Corpseout of my mind.

Vacuum does all kinds of interesting things to a pressurized body suddenly introduced into it.  A great deal of useful internal organs - and their associated bodily fluids - will be forced out of the nearest available orifice.  So, think brains coming out of ears, nose, mouth, eye sockets (after the eyes, in this case), stomach and what's in it, and a good deal of the digestive tract out of the mouth and rectum, followed by...

Oh, I'm sure you get the idea.

Anyhow, apart from all that, since there'd be major blood loss involved - and I'd just love to see that cloud of blood added to all the other biological stuff in the render - I reckon poor old Mike is going to look very, very pale.  And bloated.  Until all the air's gone, at any rate.

HTH.

OK.. let me preface this by saying BBs way is most likely more correct so this fall along the lines of a short anecdote about something I had fun playing with.

Here is what I did by mistake one time and it made a pretty good corpselike skin.  I just happened to put a mathnode into the SSS shader in the wrong spot (hooked up to the texture map)  mathnodes turn texture maps to greyscale.  It was pretty corpselike but I wanted to play with it a bit to get a little colour into it so I played with the scatter node a bit.  Checked use skin colour and adjusted texture detail a bit.  For the lips I added a bit of extra colour into the colour box of the scatter node....

anyway.. hows that for some extraneous information...

I was hoping there is already a material pose for that.

This new space death info is a really interesting. 

I still have the desire to leave M4's pretty face intact after death so that massive vacuum damage shouldn't be there at least on the realm of fiction. But for grotesque sake I will only leave the chest up to the head intact inside a cryo-coffin.

Thanks for the info.

I'm really disappointed now.  I was looking forward to a render of explosive decompression.

Spoilsport. :(

Vacuum and freefall complicates things. In air and gravity, the skin gets tinted light bluish/grey as blood settles to the lower parts of the body, which themselves become dark and "bruised" looking. I've seen it often enough.

As for that "vacuum damage" description...won't happen. People have been killed due to sudden decompression and it didn't turn into a scene out of a horror movie. Sudden massive compression, such as failure of a pressurized hardhat diving suit at depth in the ocean, will do that, but not decompression from 1 atmosphere to vacuum.

In fact, there's a cinematic version of what would actually happen: you've seen 2001, right? The scene with Bowman getting blown out of the pod into the airlock is entirely accurate (well, he shouldn't have held his breath, but other than that...). The human body can survive decompression physically (with some relatively minor internal physical damage) just fine.

no exploding body parts etc.... you freeze dry and suffer the Bends basically.

more realistically

Thanks for the article Khai. As Twain said, "What gets us into trouble is not what we don't know. It's what we know for sure that just ain't so."

Depends where you are when you find yourself in vacuum.  You will decomp in a very unpleasant way if you're left out there for longer than a few minutes, provided you're not in a particularly cold place.  Decomp somewhere relatively warm and you're in deep shit.  Probably not the spectacular explosion I suggested earlier but definitely not pleasant at all.  Air would pretty much make a mess of any soft tissues it encountered on the way out.

One of Niven's stories makes use of the idea you can survive vacuum in a cold place and use it as a survival method - basically a form of suspended animation. 

Bowman's exposure to vacuum was realistic in that he was exposed for a relatively short time and therefore lived to tell the tale.  I did, however, expect him to be deaf (ruptured eardrums), have bloodshot eyes and a bleeding nose.

BTW, I am perfectly sane.  My psychiatrist said so, shortly before I was signed off her books as being a fit and worthy human being.  Yes, I am serious.  :) 

OTOH, I have very little respect for most mental health "professionals". 

you did'nt read the article poseted? with information from NASA who's dealt with this...? they have dealt with Vacuum Exposure in warm temps ... it's even mentioned!

*to quote from the article -

"In 1966 a technician at NASA Houston was decompressed to vacuum in a space-suit test accident. This case is discussed by Roth in the reference above. He lost consciousness in 12-15 seconds. When pressure was restored after about 30 seconds of exposure, he regained consciousness, with no apparent injury sustained."

Yes mate, I did.  In fact, I read that - or another one about that incident - some time ago.

Still, it's a different set of circumstances from what I had in mind.  I was thinking more of someone being blown into space out of a ship, whilst wearing ordinary clothes, so the exposure would be immediate and total.  Even freeze drying in such circumstances would leave a lot of air inside, which has to go somewhere.

again in the article...

Have to confess I only skimmed it; I'll read it again.

Anyhow, I stand corrected.

Still it's a shame; my answer was a lot funnier. :)

BTW, you back in Blighty yet? 

i got a good vaccum pump out in the garage , i know where theres an old boiler tank..... lets settle this once and for all..... whos with me??

I could suggest one or two candidates but the Mods would have a fit.  ;)

I believe Khai would agree with my choices, too.

Vacuum has no temperature... ;)

I don't see the connection.  Infra red radiation can travel through a vacuum, otherwise all the planets would be frozen.

A vacuum near the sun is a pretty warm place to be.

I have a list....

We should compare notes.  :D
