It is done; the post production of Snowblind is finished and so is this task!
Maximum Kudos go to Hannu, who single-handedly rocked this show! Thank you Hannu for your great work, and have fun with those little playthings you got in return ;P
We'll stay in touch :D
My fellow Wreckers,
This call to arms goes out to all those who know their 3D and Roto tools!
To add the last finishing touches to Snowblind, we could damn well use some help in the VFX department.
One area is that in some shots, we didn't have the time to set up a keyable floor so the shots have to be rotoscoped - in our pipeline, it works best just to paint the floor green frame by frame, this can even be done in Photoshop CS3 or CS4.
The other challenge is for those who know how to set up a particle system - in our case it's all about snow particles. Obviously we have a lot of shots where characters walk or drive around in the snow and this would look much cooler if there would be little splashes of snow (or even fountains, depending on the shot) :D In some instances, we could also use fluid work - for BLOOD of course ^_^
We have now decided to put some shots up for download. That way, everyone can try stuff out and get direct feedback from the group. To keep the videos small, they are in anamorphic pal. Please resize them to 1280 x 720 (including a bit of black cache because the output ratio is 2:1) and then just put your particles on top.
For now we have two types of shots, "bike" shots and "walk" shots. In the bike shots we already animated a cloud of snow dust created by the wheels but it looks really bad ;-) So your task is to make something better - if you want you can also make exhaust smokes that may be a bit greyish.
For the "walk" shots we assume that the ground is frozen ice and there's just 3-5 centimeters snow on top which is rather damp. So what happens is that when actors lift their feet, just a bit of snow lumps is kicked up and falls to the sides. We don't need gigantic clouds of powder snow but for example in shot 4, the snow is definitely deeper so feel free to experiment!
Have fun,
Kalle-Max :D
Ok, this went as far as to version #4 before I even wanted to start asking any corrections in public. :) My biggest gripe I have with this is the feeling she's floating with the bike, and it is very hard to get rid of it. Then there's some other stuff like correcting the clipping of the trees and such. Also, would like to add some variance to the road with maybe some bigger chunks of snow. The scene should look like foggy dusk. More fog maybe?
I guess the final color grading & camera shake will be done by Kalle & co so won't focus on that now.
This is a lower resolution clip due to the 20MB limit. Would be nice if the limit could be a bit higher. pokes at WaM staff
Update: 05.mov, better bg track, more speed & fog.
Here's the first version. Now some good night sleep.
Update: ..02.mov, gave slight transparency for the cloud & shadow + new cloud shape.
Ok, here's the first upload for this shot. Tried to make them hit at some small pile of snow so some debris flies on top of the hood. Let me know what do you think.
Update: .._03.mov, removed the hood popcorn, added more flying stuff to the side.
Didn't do much here yet as I'm not sure where to go with this, so there's quite some hard edges and such. The snow in this version looks quite thick and even though the foot goes down quite fast, it still feels that hardly any dust would move from there. Any ideas?
Update: ..03.mov, better tracking, more stuff.
Update 02: ..04.mov, better texture for piles, some more tweaking.
Update 03: ..05.mov, more dust & more tweaks.
Update 04: ..06.mov, smoother particles, got rid of the fog "blobs".
100% recycled material, contains minor additives.
Boy was this a pain in you-know-where to get to this stage. Lots of fighting with older Blender version's particles, collision trouble.. weird physics.. and most of the time I was the error in the process. But, I think I found one bug too actually.
Aaanyway.. now I'm too (snow)blind to see if there's anything wrong here. So, lemme know, thanks.
Update: lap popcorn
Ok, some close up stuff here. There are some keying artifacts in the bike material so focus on the snow. Does it look like they're sliding downhill?
Update: _02.mov, corrected clipping and keying issues, added tracks & shadows.
Same thing here than in the last. The focus is on the particles & snow.
Used most of the time working on wheels' snow, but still it looks a bit weird. But this is very short shot so I think this might already do. ?
Update: 03.mov, more subtle amounts of snow on the wheels.
Hi!
Couple of tricky shots in progress.
This one's overall colors, atmosphere & camera movements are not in this clip, it focuses on particle effects only. I'm wondering, should the snow flying from the back wheel be more thick or is this thin(ish) dust & fog ok?
Update:
..04.mov: fixed some, added some.
Update 2:
..06.mov: more crumbs on right side and no "popping" when hitting in snow.
A version is ready.
Couple of things:
1. The easier, obvious part: splashes on the lens need to be rendered as a separate layer as the snow fall can't be on top of it, like it will come on top of the particle/dust/track layer.
2. A bit more complicated part: I've tried to do all these shots so that particle layers can be composited with normal color mixing mode, without any effects. But now, I think the snow on the lens looks better with displace as it gives it more wet look. However I can't render the layer with displace as the displace needs to bend the background, particles & snowfall for it to look realistic. There's a render without the displace too so you can see the difference and decide which is better.
Anyway, what do you guys think as overall? I like it already, but does it need more? I already tried to hide the front wheel with one splash. Also, I think the splashes at the right side take the eyes away from the wheel for a moment. By the way, I didn't add any rotation to the wheels as I'm not sure if they need it. Directional/radial blur might be enough.
Update: Bike07b.mov, edited the track and added some snow dust close to camera.
Update2: Bike07c.mov, tires have some snow now.

If that bike is unavailable I think I can use any other bike too if it is somewhat similar to the Biker Girl's bike. Turbosquid has one free but I don't have max by which I could convert it to 3ds or obj. http://www.turbosquid.com/3d-models/motorcycle-max-free/213158
Well the guys who did that model have stopped working on Snowblind due to conflict with paid jobs, but I can try and ask them... And yes, snowflakes are always welcome here ;P
Great to hear this, thanks!
One interesting image I saw here at WaM: http://www.wreckamovie.com/system/shot_medias/0000/2250/Clayton_riding01.jpg. Any change to have that model? It would help tremendously in matching the 3d scene. Also it would help in masking the fog in 3d around the bike.
Oh, one more thing. Should add snowflakes? I wanted to keep them away as I wanted to see if I can create a scene with a feeling of moving fast without them. Flakes would definitely add some motion & detail.
Congratulations from Bastian and me, this really looks quite sweet :D
The only thing that should be changed is the fact it would probably look much better to froget about the zoom and instead move the camera towards the bike! Because now, it looks like the trees would stop moving. This is optically correct of course but it looks weird and also, a "dolly movement" looks more expensive than a zoom ;P
And a liiiiiittle detail is that I think at one point it's pretty obvious that the same tree appears on both sides of the road, only flipped. Maybe you have an extra tree or just exchange that with the other one you used? Or maybe better yet, slap them both on top of each other and you have a third one ^_^
So but overall I must say that this really is much better than I expected! It may not be up to Michael Bay standards yet, but it definitively has very solid production quality, and that on such short notice... really impressive my friend :D
The composition is getting heavy as it takes now an hour and a half to finish rendering just in AE only. Update (#05) is uploading right now.
KMH : I've been watching the clips and I get the grindhouse feeling. The thing is that when you see it all the time, it'll be ok. In a single clip it stands out.
Good luck with your project. Great material.
Hannu, the zoom was done "in camera" with a zoom remote... So the only thing we could do is add a second digital zoom in post on top of that... which would be a vote for the option that we do all the zooming here, later...
And yeah about the speed; of course I didn't think of the fact that then the landscape has to be double the size ;P Well I dunno, maybe 150% speed will also suffice? Or we speed the whole thing up in editing...?
Hi Sami, yes of course you are right in all points! In Snowblind we do this stuff all the time to give a campy "Grindhouse" feeling. So everybody is driving around in the snow with bare arms, people don't reload their guns (do they ever?), shot wounds to the chest aren't anywhere near lethal and so on and so on... oh yeah, and of course riding a motorcycle in the snow without spikes or anything. This is just our idea of creating "seventies bad" with contemporary means ^_^
The only "explanation" that is given for this is a corny intro speech that states that this is a parallel universe where people's bodies have "adapted" to the cold... hehhe... this will probably put some people off but if you accept this "comic book reality" it should be fun =)
The motion is great, the boom/dolly (?) camera smooth, and the animation of the background is fluent. The expression on her face means business as well. With audio you'll have a great shot.
What worries me is not the appearance of the shot but the concept: Is the girl a superhuman and the bike a superbike of the future? Because a normal human couldn't do that for real. This might not be a problem when you see the clip in context in the film. Right now the appearance of "studio made" is hard on the clip. The details plus the following.
I don't know how much this means to you but...
- A normal person can't ride a normal bike in snow that steady - > super bike/person
- A normal person can't move that fast with open eyes in temperatures less than 0 celcius without her eyes filling with tears. Her eyes would get wet and close from time to time as a reflex -> It happens to me on a cycle in less speeds.
- A normal person can't move that fast without a shirt and keep the normal skin colour in her hands.
I have first hand experience : try downhill ski in a blizzard without your goggles. I did, it ain't fun.
Solutions: glasses, jackets, mystery powers, contact lenses, she is a terminator, skin transplants..
Of course the rules of physics can be broken (Renny Harlin's Cliffhanger. He should have known better). But I was just wondering if there is an explanation.
Well I have done lots of 3d / vfx, not just these kind of movie effects, so feel free to hammer my try to pieces if it is not good enough, I can take it. :D
The side image for shadow is a great idea, never would've thought of it. More detail to landscape should be easy to do as it is just a noise displacement. Making her move faster would be easy to modify too, but it will need some hidden gimmicks (maybe looping separate models instead as now it is just a long array) to the 3d scene as the relative sizes of the 3d objects will kill the raytrace accelerator as it is running in limits on the current setup already. I'll see what I can do.
About the zoom. In the raw file she winds the throttle but the zoom comes a bit later and smoothly. Should the zoom be synced with throttle somehow so that it looks like she's accelerating? It won't be real 3d movement towards the camera, but if the added zoom is subtle, it shouldn't be noticeable. About matching the zoom, I'll make one better match for next version and if it still "floats" I'll hand it to you guys. :)
Especially considering you having never done anything like this before, this result is pretty marvellous! I think the "floating" feeling is mainly caused by the shadow - it goes down WAY too much and is so diffuse, that it creates that land speeder feeling ;P If you move the shadow up so its level with the wheel or turn it off altogether, it should look better. I can also provide you with a side shot of the bike - oh no wait, you already have that! So use that, then it doesn't have to be so blurry.
The next step to make it all work better would be to introduce really thick ground fog, like the dry ice stuff used in 80s rock shows... make the bike sink in almost to the headlight and we have one less problem :D
The landscape is so detailed now it allows me to nit-pick... hehhe... I'd try making it all a little flatter, but with more random bumpyness. So the hills are maybe only half that high, but have many little dents (if this isn't totally hard to do)...?
Oh yes and one major point is: make her go faster, I think it can be twice as fast to give more excitement to the viewer :D
And lastly, and this is a factor that also plays into the "floating feeling", is that the zoom doesn't really match. But I'd suggest that you render the whole thing a bit bigger without zoom and then we track it on... Or I can try and export some tracking data, maybe this can be made to work...?
Thanks,
KMH =)
