A little video I made with Google Earth Studio to have nice reference imagery of eroded mountains full of branching gullies.

It's particularly interesting how flat the pre-eroded terrain must have been. Most of the steepness comes from the erosion.

In contrast, here's another recent game discovery tool I found much more useful: The Thinky Games database. The big focus on filtering is what makes it work much better for me. I can search for what I know I like, instead of wading through tons of cruft.
thinkygames.com/games/

When I stopped, I'd been presented with around 20 games I already loved, hundreds I'd discarded, and not a single new game I wanted to check out. So I think my existing means of discovery are just more efficient than a new one that wants to learn about my taste in the most inefficient way possible.

Ok, so you can flip a card to see short descriptions and genre tags, and I gave it a bit more time. But the fact I can't filter out genres I know I have zero interest it, combined with the fact the interface often bugged out, performing actions I didn't intent, made me lose my patience fast.

Ok, crucial functionality being both hidden and unexplained seems bad. But ok, giving it a bit more time now, based on this.

Tried to give Ludoscene a go, but the absolute reliance on game trailers got very tiring very fast, given how little information is often present in trailers. Trailer after trailer of just characters walking, cars driving, people talking, without indicating genre or mechanics at all. Had to pass.

Can totally see where you are coming from.

Some large scale voting based competitions devolve into popularity contests. People with large followings can encourage their followers to vote on their entries. And people may give top marks in all categories to their faves. Hoping it won't happen here.

Right. My comment was in reply to @theseahorse.bsky.social‬ . So now, for a given category, you'd only need to be in the top 100 for that category for a 1% chance to win in that category. Self-evident, I know. See the comment I replied to for context.

Being in the top 100 gave you a 1% chance of winning the jam before, and that is still the case now?

Around one cycle per month? Very close to a 25 hour day it seems.

Lovely indeed, but what I really notice in the picture is the intense commitment to pedestrian crossing signs. :)

1st image is without erosion.

2nd image is applying erosion naively. The high-frequency details confuse the erosion filter and creates lots of little spikes.

3rd image is applying the erosion to low frequency parts of the terrain only, and adding the high frequency details afterwards. Plus some parameter tweaks to make peaks less sharp and add a third erosion octave.

I managed to apply the erosion filter to my game's terrain.

Erosion Filter I ran into a nice terrain noise post from Rune, showcasing an analytical noise that behaves a lot like erosion, but without any simulation! The original seems to be from clayjohn, with improvements…

Super cool! I just had to port it to Houdini as well :)

Yeah, kind of! It can actually be used like a filter, on top of any arbitrary existing height function (with derivatives). But every point can be evaluated in isolation.

Erosion noise implementation in C# Erosion noise implementation in C#. GitHub Gist: instantly share code, notes, and snippets.

My implementation is on the CPU rather than GPU (since I need the results for further processing on the CPU).

Here's my C# one-to-one port of the heightmap and erosion noise function (making use of the Unity.Mathematics package):

The terrain above is based on an erosion noise implemented by clayjohn and Fewes in this Shadertoy:

It's really impressive, more people doing terrain generation should know about it!
#ProcGen

I learned of a cool erosion noise function from 2023 (link in reply) and wondered how it would feel in my game. First impressions:

1) It's fast for erosion, but quite slow for a noise function.
2) It looks nice from afar but doesn't make environments more satisfying to explore.

YouTube video by minutephysics The Physics Of Dissonance

Really cool video that made me understand sound harmony and dissonance at a more fundamental level:

That is somehow much better.

Weird procedural NPC names: "Beef Taat", "Is Cute", "Healer Rafu", "Lifesoy Ronap"

On one hand I should probably make my NPC name generator more name-like. On the other hand, I kinda like having a chance of weirdness like this.

I have just the thing

But it’s very possible I didn’t get it right. Gotta listen to some videos of forest walks.

Yep Bluesky normalizes the sound, or at least my videos with subtle audio are consistently way louder here. :/

It’s very hard to balance different sounds that should all be subtle. Like, it’s not supposed to sound like a windy day at all, it’s meant as ambience you “feel” more than hear.

Haha, you’re not the only one to comment on that. :) For some reason I don’t particularly take notice of it myself. The problem is, I want to evoke walking, not sprinting, but realistic walking speeds are agonizingly slow for getting around. I find it hard to assess what other calm games do.

I tried to implement the sound of rustling leaves using the same point cloud sound system that I'm using for the water.

Right! I’m interested in conveying a walk, not a sprint, but realistic walking speeds are agonizingly slow. I wonder how others have tackled this. I find it hard to assess when playing a game.

Same screenshot as in original post, but with HUD outlines dimmed to dark gray, and most of the light beige HUD elements dimmed slightly as well.

Quick mockup. Unsolicited feedback of course, feel free to completely ignore.

The layout is nice, but it’s very bright compared to the game content above. A lot of the white in it is just outlines. How does it look if those are reduced to gray, keeping the white only for the things where it really matters?
