Overt the summer holiday I built a photo emulation software for high-end photo emulation on iOS and Mac OS, can be used directly in Photos in image edit mode. Super quick, easy! All feedback welcome! You can download the app for iOS and Mac OS in the following link testflight.apple.com/join/2zP3PKz5

The GI bounces affect everything in the world from vegetation to props and vehicles

050

Jussi Kemppainen @jkemppainen.com · 26/06/2026

GI probes being recalculated in realtime to match shifting light scenarios. The probes could update every frame for ultra smooth look, but the game hardly needs that and I want this to run on the steam deck without issues!

Jussi Kemppainen @jkemppainen.com · 26/06/2026

I also build a tech I penned GI stamps to allow meshes to bounce their color to the GI probes. It is a very subtle, but noticeable effect

130

Jussi Kemppainen @jkemppainen.com · 26/06/2026

probes in shadow suppress the ground bounce and dim the sky away from shadow caster, creating nice occlusion. the suppression uses the occluder distance, letting more sky cast and bounce come trough in shallower shadow.

Jussi Kemppainen @jkemppainen.com · 26/06/2026

vehicles in this game get hijacked mid-battle and thrown across five different biomes. each one has a different sun angle, sand color, and sky. baked GI is useless here: the world is fully procedural and randomized.

Jussi Kemppainen @jkemppainen.com · 26/06/2026

day 608: ! built a fake real-time GI system for my game and it cost almost nothing to run! The warm sunset light wrapping under the car is not baked, not a probe volume, not a reflection capture. here is how it works 🧵 #buildinpublic #indiegamedev #unity3d

jkemppainen.com/ruupeli/ I built a free web-app for parents with kids with ADHD or difficulty with executive function regulation. It has a timer and a can break repeating daily routines into easily digestible pieces with gentle weekly gamification. #neurodivergent #adhd

bonkers vehicle combat game dev day 420 & 421: small things. I added pooling to the bullet trails effects and made them fade out gracefully and added support for water impact VFX for the bullets.

Jussi Kemppainen @jkemppainen.com · 07/10/2025

dev day 401: The boring machine can now finally bore! Thank you all for your great feedback 🙏🏻 I did spend day 400 just replying to you all! now, what cool gameplay could there be for this VERY overpowered worm? Now is the time for suggestions!

Jussi Kemppainen @jkemppainen.com · 05/10/2025

dev day 399: mock-up of the look, feel and motion of the boring-worm-machine. Thanks @cohhcarnage.bsky.social for the inspiration on the design 🙏🏻

Dev day 396: Hovebike first pass. Flotation, propellers and kick-off VFX added! Hoverbikes will not be common in the game, but there will be some by the end! (And other weird s***t) #solodev #IndieGameDev

Jussi Kemppainen @jkemppainen.com · 01/10/2025

vehicle combat dev day 395: I implemented wheel-less driving to prepare for hover bikes/craft, flying units and something even cooler down the line. I am honestly surprised at how fun the gameplay is with a floaty hover-unit! #IndieGameDev #gamedev #hoverbike

Jussi Kemppainen @jkemppainen.com · 30/09/2025

vehicluar combat solodev day 393: I may have turned the deformation value too high on the new school bus vehicle type :D What has not been talked about too much is that the project now has had a writer on board and we have been writing the story in earnest #realtimeVFX #solodev

Here is my game's mesh blending feature in action #indiegamedev #gamedev

Jussi Kemppainen @jkemppainen.com · 16/09/2025

Dev day 382: I ported mesh blending to Unity 6 The effect has been making its rounds online for Unreal and I WANTED IT FOR UNITY! and Finally I have it in my game. It is so nice to get rid of the nasty seams in my procedural mesh based world! #wishlistwednesday #VFX #UNITY

Jussi Kemppainen @jkemppainen.com · 07/09/2025

day 379: Many play testers asked "why does the car I just jumped away from keep fighting me?" Well, because the original driver is there with you all the time! The animation in this clip is all procedural, no keyframes! #solodev #unity3d

Jussi Kemppainen @jkemppainen.com · 07/09/2025

vehicle combat game dev day 378: added final polish to my super simple driver dynamics + hand IK + LODing replacement. Never mind the completely off animations (these will not be Flintstones cars) the tool is now feature complete! #solodev #gamedeveloper #animated

Jussi Kemppainen @jkemppainen.com · 06/09/2025

dev day 378: In order to make these as lightweight as possible, I started to work on a simple animation controller for the drivers inside the vehicles. They do not need to do much. Just steer, hop from seat to seat and react to vehicle physics and have some emotes. #indiegamedev

Jussi Kemppainen @jkemppainen.com · 03/09/2025

Crazy-desert-grapple-gun-mayhem solodev day 374: I polishes the AI a bit to take some of the terrain into account while driving around and to be able to detour after getting stuck on a steep slope. #wishlistwednesday #solodev #gamedev

vehicular combat Drivers of the Apocalypse solo dev day 371: finally started work on the snow biome. Immediately it unearthed a host sand only features I had built and needed to generalize. #solodev #wishlistwednesday #indiegame

Jussi Kemppainen @jkemppainen.com · 22/08/2025

solodev day 364: hotspots in overworld scene always visible and describe the functions better. The game's prototype playtest is still ongoing! I am thirsty for your feedback! #IndieGameDev #gamedev #UI

Jussi Kemppainen @jkemppainen.com · 20/08/2025

Drivers dev day 364: Physics objects can now have trajectory prediction, giving a little bit better idea where the bombs will land. AI got upgrade where they can break a pattern where you chip away at their health from afar. Playtest build updated. #buildinpublic #indiegame

Jussi Kemppainen @jkemppainen.com · 19/08/2025

Vehicle combat game dev day 363: year days working on the project flew by! The play-test is still ongoing, and based on the pain points people have been encountering, I added more informative texts around the UI and reshuffled some things a bit! #IndieGameDev #indiegame

Jussi Kemppainen @jkemppainen.com · 12/08/2025

Jussi Kemppainen @jkemppainen.com · 10/08/2025

Drivers dev day 351: UI audio pass. Still nearly not done, but we added some physical sounds to the UI's. I think they wonderfully add to the feel. HDD clicking when new data is accessed and fat keyboard sounds when navigating. We still need much more PC beeper sounds! getting there! #indiegames

0275

Jussi Kemppainen @jkemppainen.com · 06/08/2025

Drivers OTA dev day 352: animated brake lights (+ day 340 varied and better engine sounds for the vehicles) I have fixed dozens of bugs and added playtest specific features. Polish polish polish! #IndieGameDev #unity3d #wishlistwednesday

Jussi Kemppainen @jkemppainen.com · 29/07/2025

Dev day 345: first steam deck test. My game ran at around 40+fps with medium*ish settings in a high stress scene. FPS locked at 40 with some more settings tweaked is a very smooth experience 👍! #indiegamedev #wishlistwednesday #steamdeck

0210

Jussi Kemppainen @jkemppainen.com · 23/07/2025

Drivers dev day 343: what! Another dev diary! It's been so long! I spend the whole day adding full controller support to the in-game store. This is by far the simplest computer UI in the game, and I need to make all of them have full controller support. Not fun work! #indiegame #gamedev #solodev

Jussi Kemppainen @jkemppainen.com · 10/07/2025

Vehicle combat game dev day 339 (contd): Support for full color stencils added. You can now upload Any image (square aspect ratio) to use as paint stencil in the vehicle paint booth. Completing the tools for maximum customization and perfecting the TTP! #wishlistwednesday #IndieGameDev #gamedevs

Drivers of the apocalypse dev day 324: randomized oil pipes snaking through the desert. As you may know I have been wading through writer applications the last week, but I managed to squeeze in some actual work and added an oil pipeline to the game! #wishlistwednesday #indiegamedev
