This was a really fun vehicle to make! Loved making the rig and had tons of fun just playing around with it and recording for it! I'm going to try using a dedicated account for Sacrilege and see how it goes. If you are interested in Sacrileges content make sure to follow @playsacrilege.bsky.social!

Sacrilege had problems with explosions being pretty inconsistent--Going through walls (bad LOS), not affecting things right next to the explosion, weird physics, and more. That's all been fixed! www.playsacrilege.com #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

Just learned what opengraph is. Basically its web tags that determine how your link appears when posted on Social Media. I added those tags for Sacrilege and I think it looks a ton better! www.playsacrilege.com #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

Have they become too self-aware? I wonder what they are thinking... 🤔 #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

I definitely feel like this "gibbable parts" system is going to be a headache to setup and is going to take some thinking, but im starting to get somewhere I think? #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

I think I'm finally understanding quaternions, which has made things like physics-flying vehicles possible for me. The Hornets are much more stable, anddd I worked on the AI for it! Download: www.playsacrilege.com #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

What are your favorite vehicles throughout Halo? What do you think would be a cool addition for me to add? This is what currently exists in Sacrilege - Mongoose - Gatling Turret - Gauss Turret - Warthog (And turret variants) - Transport Warthog - Scorpion - Ghost - Spectre - Wraith #Halo #gamedev

Do any other game devs just routinely feel lost in the job field? Have a degree, experience programming in game engines... but most places hiring want professional experience. Super confusing, just sending out tons of applications and just hearing nothing. Looking for advice! #gamedev

Forgot to ask, but if any of you have any free sound library recommendations, I'm all ears (especially like sci fi or things that fit the objects in this clip)! My Hard drive died alongside my built-up collection of free sound libraries 😢 #Halo #gamedev #indiedev #UnrealEngine #UE5

One really small thing I did yesterday was add hitbox-based damage multipliers, and adding physic reactions to headshots akin to Halo 2. Much more satisfying to score headshots. Download (free): www.playsacrilege.com #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

Cranked out a minimap/radar system yesterday. Not a lot of info on creating one, but wasn't that bad to make. Satisfied with how it came out (will get polish) (Radar enlarged for dramatic effect) #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

Making things a more reactive to physics forces (even more chaos!). Characters get launched by strong forces, and vehicles can get launched too. Next up is to affect projectiles too! #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

Refactored my grenade system and HUD. Made an editor tool that allows me to take screenshots and make icons really quickly, which helped to flesh out the UI a lot. (Shameful repost due to outage right as I posted) #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

I LOVE JIGGLE PHYSICS. I really wanted my Warthog to feel a bit more lively, so I added some bouncing/moving parts. Using 1 bone each which doesn't look as good as it can be but keeps performance costs low. #Blender #B3D #UnrealEngine5 #UE5 #gamedev #Sacrilege #Halo #indiedev #rigging

By far my favorite weapon prototype I've been working on this week, the Needler from Halo. Came with a lot of challenges (which included a lot of crashes) but it's so chaotically, ridiculously fun after all the work. #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5

Started a basic Warthog model and couldn't resist making giving my AI the ability to drive wheeled Chaos vehicles. I think the Grunts are having a little too much fun with it but are also terrible drivers 😂 #Sacrilege #Halo #gamedev #indiedev #gaming #games #UnrealEngine #indiegame #UE5
