Decided to try implementing camera-roll when strafing without relying on broken physics. It works reasonably well, using the same quaternion spring damping as my weapon-recoil camera shake. This is more camera shake than you'd want for a casual FPS, but might suit a tactical one.

Turns out if you accidentally break some player rigidbody interpolation logic, your game ends up feeling like the game Bodycam. Maybe this was their trick all along. The accidental lean is cool tho. Windows having bad HDR capture making the game look super overexposed also helps

@Peter_shirley I think it's a temporal reprojection issue because the contrail didn't write motion vectors and the camera is panning sideways quickly.
English
Shadow of contrail on other clouds looks like a graphics bug to me 🪲🌞⛅️

(Here is the less broken version for completion. Trying to find a nice balance between root-motion/animation-driven camera/player movement, procedural effects, and control. Making it framerate+physics framerate independent is a fun challenge, this is for multiplayer+perf reasons)

@SheriefFYI It stopped happening when I updated my drivers unfortunately and this was one of the only cases where I wasn't even getting a crash dump or error message. was only able to figure it out by managing to attach a debugger before it crashed on startup. (Which is the above screenshot)

Sigh, it was a f-ing PSO cache issue. Have never had this happen before, somehow it was attempting to retrieve an invalid cached PSO. Deleting the cache didn't seem to help though, had to do a GPU driver update and a full project reimport. I love not having helpful error messages

One of the worst things about Unity people don't often mention is how bad its error and crash reporting can be and how utterly impossible it can be to diagnose an error without source code or even a coherent error message. (Or in my current case literally no error message at all)
English
@aliasedFreq Fair, Unity is usually reasonable but last few months am always getting crashes from their internal code which it just reports as a SISGEV error without any helpful info.
In the above case I was not even getting that, just a silent crash with no output to the log whatsoever.
English
@BenSimsTech not defending unity but elegant error handling is literally the hardest thing to design in huge codebases
English
@SheriefFYI Nvidia (RTX 3070). Was working fine one night, the next day, instant crash on launch. (Maybe something updated inbetween) Only explanation I can think of is that it somehow cached a bad PSO and it was then trying to retrieve it when I re-applied my edits.
English
I often see "Use a PID controller" in response to "How do I achieve a given rotation using physics/torque?"
If you know how the physics engine updates rotation, you can derive an exact torque.
This is the code for Unity/PhysX, and an example rotating in a single frame.
English
More often than not these days it comes down to selectively reverting changes until the crash stops, repeated attempts at clearing the library, sometimes attempting an engine update in a desperate hope it will either stop crashing or at least give me a bit more info or context.

@Dispatch_Graph Yes and no, quality of living is good here, game job opportunities are very limited though. Sydney and Melbourne have more opportunities, but much more busy and expensive to live in. Most successful studios here are niche/small groups, bigger studios seem to struggle long term.
English
@BenSimsTech Nothing related to silksong but is Adelaide/Aus in general nice to live in for games? Everything in Aus is around Sydney but I’ve heard it’s kind of a shithole
English
I work in the same building where Silksong was made, AMA.
(But don't ask me anything about the game or its development or the developers because I have no idea. (Though I did talk to one of them about water shaders once) Actually, probably just don't ask me anything at all tbh)

I need $1M in funding to make UE rendering better. As opposed to TI, I've already made progress by having a branch up, so you know I am legit:

@PaperMartinDev @fletter_io Half the problem with developing fundamental knowledge these days is that instead of a 2-paragraph blog post and a couple of code examples you have a 5-part YouTube series which is mostly the creators life story and favourite keyboard and IDE, plus product placement and memes.
English
@BenSimsTech @fletter_io Ppl wouldn’t have so many issues with misinformation or outdated advice if they acquired fundamental knowledge & tracked information to its source. Bad information on how to say, reduce draw calls is a non-issue when you actually know the process through which the engine
English
Tbh I'm pretty sure if we all stop talking about TI it will literally disappear. Its infamy is really the only notable thing it has going for it, and anyone who actually knows what they're doing already knows they have literally 0% credibility to their name. Its pretty simple imo

Looks like Threat Interactive RAN IT BACK. He re-uploaded his latest video and edited out the part where he told his audience to go review bomb and leave negative reviews on all UE5 games. “Our legal team has advised us to republish a slightly edited version of this video. We are not at liberty to discuss our reasons in detail at this time but we will revisit this topic in a few months. Right now we want to focus on the production of our next video”. WITH YOUR SUPPORT, we keep Threat Interactive Accountable!

@BenSimsTech agree and not in the same time.
if i got one $ each time an user tell me nanite is bad them link a TI video...
English
@BenSimsTech Or push harder and achieve lolcow status?
The boycott thing already bit him in the arse.
