Tire tracks, the 'railroad way'. C&C welcome.
Veeery nice Ulco, this is really cool!
The tracks look terrific, very convincing.
I suppose the profile is also procedural?
The shallow flat water is a very nice touch and exactly the same thing I would do when I would have something as nice as this in my hands :)
Great work!
Cheers,
Martin
Really good!
Would love to see this animated.

Thanks, guys. Here's another one. And no, the tracks are not procedural, but a repeated mask. It could well be possible to find some math to get this profile (inside a simple shape), but I'd rather use a small mask, which is much easier than all those blue nodes. It would probably need a bunch of semi-overlapping simple shapes to contain the different patterns anyway, too much work.
I'm not pleased yet with the wet sand edge, the wet tracks, the sand itself and such, but as usual, this grew from testing my mask.
Looks very good. I remember trying to do a scene with water-filled tire tracks many years ago with a very early alpha, before the Technology Previews were released. This is much better than anything I managed. ;)

The Technology does all the work ;) Some muddy water-filled tracks in a plowed field would also be nice, indeed.
A better version. I added a RT reflective shader to the car, set at refraction 1.5, which is quite nice, IMO. And it might seem that the tracks are much wider than the car 'gauge', but they exactly fit!
Excellent! This could easily be mistaken for a photograph
I've made another (tractor) tire mask. Now for some decent landscape....
Wow. That looks extremely good!
These are really looking very good Ulco.
But this one is better, and the next one will even be better, rendering now.
awesome work, the first thing that comes to my mind is the famous Escher woodcut http://en.wikipedia.org/wiki/Puddle_(M._C._Escher) (http://en.wikipedia.org/wiki/Puddle_(M._C._Escher))
Nice one, I was indeed thinking of making footsteps as well. It all works the same.
QuoteI really have nothing bad to say about them
That's a pity; I was hoping for something really bad ;)
I made some new dirt, and quickly grew some maize stumps, although they are not too good yet.
I seem to remember that wet dirt tends to curl where it has been squeezed out of the tire ruts.
It's the only real bad thing I can think of. Sorry Ulco. It's really very good. :'(
Looks very good , Dune :)
You know it too , but i think the only thing you could add is some soil patches (broken ,fallen ones) in the middle on the tracks .
( Couldn't quite understand but this is the same what Njeneb says above maybe)
And while you're at it you should change the tire pattern,that smooth/flat
middlepart looks soooo wrong ;),to me at least.
It's like when a kid uses a Play Dough factory. The mud gets squeezed up the tire sides, clumps, then falls off into a sort of solid tube shape. Pieces do end up in the track itself also.

I was sceptical on that til I looked closer. A bit more colour correction and that genuinely is a superb bit of terragen work.
I know about the tire profile. Who'd know I'd be studying tire tracks :D Here's another version, but I get the impression the stalks don't really follow the sinus rows, have to check that more careful. And the loose bits of squeezed mud are an interesting challenge as well.
I'm sure you'll get your graduation in tiretrackology soon. ;D
The latest render is really awesome! This reminds me of being a young teenager and working on various farms.
Looks really awesome Ulco. Very believeable.
Still have to change tires, and get the stalks on the tops instead of in the 'valleys', but the rotation is a fact. The displacement is a bit too much on the tops.
Specular on the vehicle is too rough. If you're going for a dirty/dusty look on the car, dirt doesn't increase roughness of the specular, it masks its intensity. The specular itself should have a very low roughness to create a very tight highlight.
Very realistic work Ulco, I really like it!
Nice fence model too. Did you model it yourself?
Cheers,
Martin
great job Ulco, also reminds me of the years i spent working in the Bollenstreek near the dunes...great scene!
Thanks guys, and you were just in time, Matt, I was just starting another render, but changed the reflection roughness from 0.1 to 0.02. It's an added reflective shader (RT) after which some dirt PF. Next one will also have better tire tracks and puddles of water.
@Martin: self modeled, indeed.
Somehow this render took ages (3x the last one), and it might be the water, although masked out (but slightly curved with the soil). It may also be the more reflectiveness in the lower parts...
Cool stuff Ulco :-).
Ulco, the things you do with terragen are just awesome to watch!
Stunning work
Awesome Ulco. It's a thought provoking stuff. Both visual and procedural wise
So real. Yet, I would be tempted to not have the crops look like crops (in rows); but, rather go for random patches of weeds. In all, this is an extra special piece.
Just another thought; I would like to see a Mars scene with the tracks of the Rover plowing along the terrain (or should I say the Marain).
QuoteMars scene with the tracks of the Rover
No problem ;)
I made some other maize stumps, with dried leaves on it, might just do another one, although I'm busy again with my trains now.
Well, you supplied me with an idea. Does this look like Mars a bit? With reference picture in the next post.
from the internet, I liked the 'vulcanic' looking rocks.
Insane details. Great mud shading. ;)
Ulco, this is exciting ... the colors; atmo, surface and rocks are right on. - and, those tracks are amazing. Sure wish you could teach us how to produce them.
Here's a better render. I read that the Mars atmo is kind of dusty. Plucked a Rover from the web, but I haven't changed the glass and such yet. Just dumped it on the surface. I am thinking about how to make the 'flakes' that stick out in the reference photo....
The tracks are a photoshop painted square mask, set to 0.6m wide, repeated Y-wise, fed through a transform shader to get the second track, and then warped. This whole set is duplicated and the warping fractal (or Perlin 3D for smoother effect) slightly changed, so you get front and back wheels slightly different in corners (like in real life). Then merge it all together. This should get you on track ;)
Very nice. It's difficult to tell if this is rendered or a photo. It looks very much like the test area photos from JPL.
Thanks Ulco for this explanation. This iteration of your image is very good. I can visualize an image where the Rover is at the edge of a deep crater with tracks behind.
Always on the outer reaches of breaking the reality barrier, Ulco! Great stuff over the last few weeks!
