This is what chaos looks like before handling the traffic
I fixed the issues in the editor and removed the ortho<->perspective coordinate translations, it’s now purely perspective. It’s stable enough to finally start working on traffic handling.

Meanwhile, @piro is having a hard time designing the scene because the editor becomes quite unresponsive(I know it is a known issue). As more people start using 3D with Defold, the editor’s model handling performance is becoming a real issue, even with the low-poly models we’re using.

Added a very quick and dirty Depth of Field with different blur implementations:

1. Circular - 8 directions, most complex (I think this one looks the best though)
   

   

2. Two passes (separate vertical and horizontal), so more like cheap Gaussian:
   

   

3. One pass, one direction, simplest, looks more like “smudging”, so most awful, but I bet it’s fastest (I did not benchmarked them yet though):
   

   

Definitely the strength for screenshots 2 and 3 are too high, but I wanted to use in all the same settings, just compare methods. It’s screen space and the blur messes with shadows.

Nice!
In the #2, the two-pass, it looks like only one pass (Y)?

@Mathias_Westerdahl

Yeah, looks like, but maybe it’s because Y is second? It’s a very dumb implementation. When I make it in the other order the smudging is more visible horizontally:

[selimanac]

Aha nice work. I also planned to implement Depth of Field if there is any time left

[ackle]

Are you implementing the separate passes with the same material/shader, and using a uniform to set the blur direction? I’ve tried the same, and I think there may be an engine bug where the second draw call overwrites the first. I haven’t had a chance to make an isolated test case and file a GitHub issue though.

[ackle]

@Mathias_Westerdahl @Pawel I’ve filed this issue, which I believe is causing the problem observed in the 2-pass blur. I’ve linked to a repro, and have been working around this issue for some time now in my own 2-pass shaders.

I want to creat a 2d sci-fi office environment that has some people working（mess around）like patlabor hahaa

[Pawel]

Awesome idea!

Here’s my progress, added sky box, played today with city building. A little trick to make medieval scenes more interesting - put off-grid and rotate everything a little bit!
I believe there weren’t any strict city planning rules back then

cartoon version kindom come deliverance

GTA 1 level traffic

Mostly a brute force solution, but I guess it is enough for a project like this. There are a few small things to fix, like rotation based on speed, and then I’m done with it.

Eventually, accidents will happen and traffic will jam

I don’t know why the cars are jittering in the video. They look very smooth while running. I couldn’t figure it out.

[Pawel]

Nice @selimanac! But looks like cars are aware of each other and stop to pass others through!

I’m not a driver but this is how the traffic is supposed to work, right?

[Dragosha]

Are these all bmw drivers? I don’t see anyone showing a turn signal.

[selimanac]

Someone has to teach them the rules, so I added the traffic lights to stop those bmw drivers

[NaakkaDev]

Haven’t had as much time as I would like, but its getting there. Good thing there is still 11 days left!

Small teaser.

[selimanac]

I think I got the depth of field too

[Pawel]

@NaakkaDev

Atmospheric!

@NaakkaDev

Yeah, there is a lot of time still!

@selimanac

Looks great! Coming along nicely!

[selimanac]

Kind of starting to look like something. I found a terrible issue with the new DoF and I do not know how to fix it yet. I guess I have to take a look at it for a few days. But it looks good I guess

I have no idea why the video is jittering. I tried to record at 60 and 75 with many different settings but no luck

The newest 1.12.0 beta introduces an improved scene view rendering performance in Editor when models are in it - so, it’s a great opportunity to check out your scenes with it and tell us, if it is better in your cases
