I don't know about all the rendering issue with LuxRender but I do have an idea what Daworm may be talking about with the pipes.
I'm assuming that one of the Xenomorphs must have pushed it's way through that hole in the ceiling or something very heavy must have fallen through that patch. I'm inclined to believe the former as this is a Weyland-Yutani colonial pre-fab construction at work here. Yes it's true I am an ALIENS fan of super geek proportions.
So if the Xenomorph pushed it way through the those pipes, maybe trying to get at a colonist under them. They would either be rolled back more and almost none of them would all be rolled in the same angles Next, those pipes wouldn't look as if some machine had bent them that way. some would be flattened out at their stress points where it's bent.
Next the ends, the ends are too cleanly broken. Yes I see that the ends are all jagged and sharp. but they are perfectly rounded. "If" some thing that strong ripped those those pipes like a beer can, those pipe ends would be flanged and torn through, some area's flanged out and stretched whole other pulled inwards towards the inside of the pipes. the most stretched areas and the most flanged out area would be the opposing side of the direction the pipe had been moving to get that way in the first place as that would be the direction that game the most resistance to the force moving it in many cases.
Lastly, We all know that the Xenomorph has a highly corrosive form of acid for blood. this is what makes them so darn deadly to kill. you may not get caught in the splash of blood after killing one of these things but if you happen to also be in space on a ship and kill one on board your ship. that much acid would eat it's way right through your hull and then your screwed as the vacuum of space would suck almost everything out into the void. Can anyone say Explosive Decompression with a chance of instantly freezing the Giblets of body part that was once you? yeah gross huh. It's one of the factors that make Space travel so dang risky as just about anything can still punch a hole in the space shuttle and kill a whole crew in a matter of seconds. thank god that hasn't happened. yet...
I bring up this fact for a reason. If a Xenomorph was to tare that patch of pipe open, it would likely also have to slice itself open doing so. IE it will bleed all over those pipes and anything else it in that tight area. how much entirely depends on how badly and how much fury it laid into those pipes to get through. We know that the Xenomorph is a primal yet intelligent creature, it may have even cut itself intentionally to make getting through those pipes all the more easier. thus we can assume that many of those pipe ends as well as the pipes them selves are melted like a McDonald's drinking straw in a cigarette lighter's flame. this would not just effect the ends of the pipes but rather maybe even the whole section of pipe itself and deform it is a rather wildly random looking shape maybe even fusing a few chunks together some how.
As the PH value of the acid is burned off, it will start eating less and less until eventually the PH is totally naturalized.
In the film Alien (Ridley Scott, 1979) there was a scene where they tried cutting the Facehugger (Not my term, please don't give me crap for it) off of it's first victim, A crew member of the Nostromo named Kane (Played by John hurt) and is so attempting to cut the fingers of the Xenomorph Facehugger to get it off of Kane's face. a little bit of blood squirt off and spills onto the operating table, through the operating table, through the floor, out the ceiling below that through the next floor down for I don't remember how many decks, a few for sure I remember, Maybe three or four visually, and maybe five or six in subsequent conversation afterward. the fact is it ate through a lot of we can only assume specially tempered steel and god knows what else between before finally unbalancing the PH and coming to a stop several floors below the medical bay.
How much blood was that? From as far as I can tell, about a 1/2 to 3/4 teaspoons worth of gritty yellow acid blood. Yeah imagine what a whole fully grown Xenomorph worth of that stuff can do if it bleeds out unchecked. they would have been screwed over most ricky tick.
Let me ask you something, Is this a scene from LV-426 (the planet's astrological name from James Cameron's Aliens in 1986) and if it is, At what point does this scene take place? I'm assuming it's after Newt's family, follows Carter Burke's instructions about how to get to the Derelict, comes back to the colony with a facehugger in tow. but I do not see any signs of the Colonial Marines having even landed. So I'm going to have to assume that this scene takes place between Initial discovery (or rather rediscovery) to the point in which the marines orbital to surface with Ellen Ripley and Carter Burke along for the ride.
If you ask me taking them all down at once and having a single squad was universally, and tactically stupid. surely the Sulaco is capable of taking upwards to 4-8 units at a time. the average Unit being anywhere from 12-16 people...
- NCO (Non-Commissioned Officer)
- Drop ship Pilot
- 2x smart gun Operators (Squad Assist Support Machine Gunners)
- 6-8x Riflemen (One of which being a Security Subversion Tech)
- Technical Adviser, some sort of liaison or the like if needed more is needed.
but that's just fluff talk right now...
Next, It seems the scene is far too clean. I mean that literally by the way.
If this is the time between Discovery and Colonial Marine touch down, then the scene could be a bit cleaner or cluttered depending on the situation. Like if this is Initial Civilian Defense Attempt it a little bit cluttered, Like it's being lived in. After all these are civilians with their families, living in a tight space trying to work and live in the same place. Things are going to be places a bit haphazardly here and there as they go about their daily lives in the Colony.
If this is moving on towards the Civilian Defense right up to the Last Civilian Stand the whole scene would become way more trashed. things are going to be flung around the hallways and rooms as the Colonist try and defend them selves in the battle(s) that ensued. Some wall panels are hanging open or even tore completely off and on the other side of the hallways. some tore off and welded into containment walls which we all know eventually failed.
Paper work, books, manuals and files where flung every where. I remember in one scene, Kinda hard to see, there was a small area where it looks as if some of the survivors of the initial attack had just gathered up a pile of papers and looks as if they had burned them making a small camp fire for warmth.
Some of the wall panels have the wiring torn out or spliced in machinery/generators. Overhead ventilation was torn down, there where signs of small arms (Hand guns and smaller caliber Rifles) fire, Servery Charges blast marks, and other improvised weapons all over the place as they desperately, and eventually hopelessly tried to defend them selves. it's almost like a hurricane of Activity and Violence blew through the place in stages.
Floors and walls showed signs of having been splashed but misting of the acid blood, some areas there are holes where they may have actually hit one but didn't kill it. One place for sure they killed one and it melted a hole in the side wall and the floor a good ways downward. Some of the rails and walls are dented severely as if something rammed it rather hard or one of the survey charges went off right at that spot pushing all the surrounding metal all over the place if not totally blowing it apart.
All and all this was a scene of a horrible and ultimately hopeless battle. It's not going to be clean like that. in fact it's going to be really rather chaotically dirty and cluttered. even if this is before initial attack, when there where only a few Xenomorph's and almost an entire Colony of Human there, the lived in clutter is a factor as well. It still wouldn't be so clean or free of clutter.
There are scenes in Special Edition of the 1986 Aliens where we see the colony in normal operation. there are boxes and Drums in the hallways as a little kid is riding his big wheel toy in the Halls. There are people working on some of the walls panels, there are some spark of them welding something into the walls I believe. Also it was a little bit grungy. Kinda smoky, I have assume from both the Welding and the smokers puffing on cigarettes or pipes. the lighting was more solid, and operational but ti still was a bit dim in the halls. Some of the wall panels where in fact opened, not many but a few. there where wires being spliced into and re directed here and there and a few hose like wires draped down from walls and ceiling. And all this was before they found the Xenomorph's if you'll remember.
Basically, it was a mess but more of a living in mess with all the hassles of living in Tight spaces with hundreds of other families and co-workers.
When I say your scene is far too clean, I really means it far too uncluttered and well, sterilized clean looking. I do understand that this is a 3D model and that it took a lot of work to get it to this state and I applaud the work you put into this making it looks as good as it does. Also I understand that the more Detail you put into this the longer it take to render it looking as good as it does already. But there just not enough clutter to feel really lived in or more visually potent, fought for their lives in. And thus it feels fake somehow.
I ask you to at least take this into account and try and bring a little more life into the scenes. You don;t have to pack the scene with a whole lot of clutter. even just a little can make a world of difference.
All and all it a pretty accurate looking scene pre destruction and even before being lived in. Keep up the awesome work.
One Last thing, Have you been Working on a Xenomorph mesh? I remember there was the tail section of one in the scene you made before. But I hope that you are building a fully modeled version with the same attention to details you've show thus far with the scene. ti would be awesome to see one maybe even for a few seconds in your animation...
