Justin113D @justin113d.com · 11/09/2026Unfortunately, due to throughput and packet loss, connecting to the Pico via bluetooth is not suitable for when intending to use gyro. Here my PC is communication with the Pico via a USB-TTL serial adapter, which is connected to the Picos GPIO0 and GPIO1 pins 131
Justin113D @justin113d.com · 11/09/2026Finally managed to get the gyro working! It took some researching to figure out how the gyro data and other related parameters are formatted, but it's finally working like i intended it to! The mouse translation is not absolutely perfect, but very much usable! Just needs some getting used to... 171
Justin113D @justin113d.com · 04/08/2026I got a new little toy~ I've always loved the idea of programming hardware stuff, and now i finally got a reason to! Specifically, i wanna see if i can translate keyboard + mouse controls to switch 2 controller output, send that to the pico via bluetooth, and then pass that to my switch 2 150
Justin113D @justin113d.com · 14/07/2026I have finished my Sonic Adventure 2 Chao World #MecchaChameleon map! steamcommunity.com/sharedfiles/... Been quite a ride figuring out the best way to get this into Unreal Engine! 0195
Justin113D @justin113d.com · 05/07/2026Small thing i am working on; Custom map for Meccha Chameleon Still very WIP 172
Justin113D @justin113d.com · 08/06/2026What just occured to me: "Man, I hope the rumors about a nintendo direct next week hold true... lemme look up what rumors are saying" [picture 1] "haha, that looks like one is taking place tomorrow! how funny!" "..." "WAIT" [picture 2] "THEY ANNOUNCED A DIRECT A COUPLE MINUTES AGO, FOR TOMORROW?!?" 181
Justin113D @justin113d.com · 20/02/2026Just released HedgeMatEdit version 1.1.0! Now sporting multi-file editing, with which multiple material files can be opened and edited at the same time! github.com/hedge-dev/He... #SonicModding 0183
Justin113D @justin113d.com · 04/02/2026Me channeling the power of the stars to summon a Dragon Quest IX remake announcement 040
Justin113D @justin113d.com · 02/02/2026More than a year after starting work on this, it's finally here: The full release of Hedgehog Engine Blender I/O! github.com/hedge-dev/He... 33817
Justin113D @justin113d.com · 31/12/2025After an insane amount of work, i can finally publish both my silksong supercut (which had to be split in 2) and my new update video! youtu.be/GJXOyVFw75Y youtu.be/5_rnxwwa9Ak 081
Justin113D @justin113d.com · 01/12/2025After 2.5 months of nonstop work, it's finally done: My #Silksong Supercut is basically ready to see the light of day, with a runtime of 14 hours! I know this is something completely different than what I usually make, but I am super proud of this and hope everyone has fun watching this! 190
Justin113D @justin113d.com · 22/10/2025Editing gameplay footage is a much more time consuming effort than i anticipated... but i now went through my 72 hours of #Silksong footage! Now, 16 hours is a bit too long, even for a supercut, so i'm gonna have to go over everything again and find ways to save time lol. 020
Justin113D @justin113d.com · 13/09/2025I completed #Silksong 100%, and did so 100% blind. Absolutely game of the year, 12/10. 070
Justin113D @justin113d.com · 04/09/2025It took me 2 and a half fucking hours until i could finally purchase it, but nothing can stop me now! 010
Justin113D @justin113d.com · 04/09/2025See y'all in a few weeks. #Silksong (original video: youtube.com/shorts/882pZ...) 170
Justin113D @justin113d.com · 02/09/2025I arrive at work after 2 weeks pto and first thing I see is this lmao 0240
Justin113D @justin113d.com · 25/08/2025I realized that i probably should have made the vertex color and blend factor linear before displaying, whoops! Did that now, here is the correct graphic: 040
Justin113D @justin113d.com · 25/08/2025Working on #SXSG shader docs, just finished writing hedgedocs.com/index.php/Sh.... By using RenderDoc and my decompiled shaders, i can make fancy example graphics showing how advanced shaders like these work~ Hopefully this will help newcomers understand how to use these shaders for their mods! 2121
Justin113D @justin113d.com · 17/08/2025It appears there exists no proper standalone editor for Hedgehog engine materials... until now! Spent a few days putting it together using my Avalonia libraries. Right now it only does the bare minimum but will receive more features (like shader templates) in the future! github.com/hedge-dev/He... 0287
Justin113D @justin113d.com · 10/08/2025I've been doing more #SXSG shader reverse engineering, reached the shaders that blend texture sets now. One of them, DirectionBlend_dpnndpn (used in kingdom valley), has a bug that incorrectly applies the third normal map. I checked out how it looks when fixed, and it does make a difference! 0155
Justin113D @justin113d.com · 27/07/2025Alright, i finished reverse engineering the common vertex shader from #SXSG! This means i now have all major boilerplate code done to ramp up shader reverse engineering next week! As a bonus, have a vibrating Shadow (he accidentally hit his elbow): 3303
Justin113D @justin113d.com · 27/07/2025Update: It was immediately recognized as the special warping effects shown in the recent autodesk interview! (area.autodesk.jp/case/game/so...) 1160
Justin113D @justin113d.com · 27/07/2025Been reverse engineering the #SXSG vertex shader, and found something referred to as "deformers". I could not find these used ingame so far, so i replicated the effect in blender using geometry nodes! (If anyone saw something like this used in SXSG or frontiers, please inform me, thx) 1497
Justin113D @justin113d.com · 10/07/2025I have finally fully reverse engineered the #SXSG deferred rendering shaders & the Common_dpn shader. Took almost 3500 lines of HLSL code, but now i can start working on other shaders too! Big thanks to @skyth.bsky.social again, this would've taken forever without him! github.com/hedge-dev/Ne... 0327
Justin113D @justin113d.com · 01/07/2025I finished reverse engineering the SXSG deferred rendering combiner shader! So much cool stuff happening in there, i hope i get to apply much of what i learn while doing this in SCR or other projects in the future! I still got a lot ahead tho! Also, have an inverted Shadow~ #SXSG #SonicModding 1243
Justin113D @justin113d.com · 25/06/2025Testing the local-lights part of my reverse engineered shadow generations deferred shader. Makes for some neat pics! #SXSG #SonicModding 030
Justin113D @justin113d.com · 16/06/2025So i guess this is gonna be my life for the next few days 2331
Justin113D @justin113d.com · 14/06/2025Finally got a major portion of the common shader code in SXSG reverse engineered... which means i can do stuff like this now! #SXSG #SonicModding 2233
Justin113D @justin113d.com · 12/06/2025Hmmmm... Something isn't quite right, but i can't pinpoint what exactly... 061
Justin113D @justin113d.com · 10/03/2025I was able to replicate the Sonic Unleashed fur shells in blender! Gonna put this in HEIO one way or another. (Big thanks to @skyth.bsky.social for providing the shader from unleashed recompiled) 14714
Justin113D @justin113d.com · 18/02/2025Artemis decided it's time to sleep on my arm while i am programming again 1141
Justin113D @justin113d.com · 05/02/2025I've come to make an announcement: HEIO Finally enters the 1.0.0 release phase! This means that all features and the manual are complete! Now all that is missing are SXSG shaders, which i will get to right away! (also, bug fixes, if any are found) (I also finally got around designing a logo!) 29429
