What I'd like to know is, is there a pre-existing tool to turn THIS into something more like THAT?
Not necessarily with the names, but just without the superfluous variables everywhere.
I did it by hand here, and this is one of the shorter, simpler shaders in ACNH. The interesting ones are much bigger.

For #renderdoc is there no way to get its timeline to scale according to *actual time taken* rather than uniformly scaling it for every event as it does by default?

It turns out I *can* in fact brain hard enough!
Considering I started this task at 10:48 and finished around six after midnight, I'm starting to smell a pattern here. Something something best work at night?
I took screenshots of the process too in case anyone's interested.

In order to debug the vertex generation for non-full voxel path tracing I switched over to simple ray casts as the shaders compile faster, allowing me to iterate more.
Some time with Renderdoc debugging of the Vulkan compute shader has solved a few issues, and if you squint it almost looks alright.

Ah, the joys of being a graphics programmer.
I got a bug report that there are black artifiacts on every #AMD #GPU. My development machine has #NVIDIA and did not show any artifacts.
Turns out there is an asset with unspecified vertex colours. And NVIDIA defaults to white while AMD defaults to black. At least in #OpenGL. I wouldn't be so mad if this didn't take me half a day to find in #RenderDoc.

Vulkan/DirectX beginners please use #Renderdoc. It can give you more insight on validation errors (like what's the value of a flag that is erroneous). I just fixed a bug for a fiverr client that was caused by a small code mistake but so hard to find without renderdoc's insight.
Nevermind, don't use renderdoc, I need fiverr money :^) -
OK #RenderDoc is incredible.
Assuming you managed to dive through the insanity of the glslang API¹, you can actually debug a single fragment shader from their #GLSL form.
Being able to observe the exact values of everything is absolute bliss.
The debugger is basic but there is one incredible option: "Run forwards to NaN/Inf". This is going to be particularly useful to me and my gigantic shader full of nested loops.
Note: this is not possible with OpenGL.

I've been skeptic about #RenderDoc but the more I dig into it, the more I like it. Today while trying to make the shader debugger working, I found the shader editor (useful for live change debugging), and also the way to add a custom view on a texture by writing a custom shader snippet.
Typical use case, here I have a signed distance texture, and I'm using a custom #glsl fragment (the sdf debug color scheme from Inigo Quilez) to display it. I love this.

Got it working with UE5 on the weekend, so I can import a Renderdoc capture, extract the dispatches and debug it. Still pretty rough, but stepping through the UE5 Hi-Z build shader is awesome. Oh and the D3D12 capture is running in my Vulkan renderer! #UE5 #renderdoc

Just discovered #renderdoc https://renderdoc.org, I've been looking for something like this for 18 months for OpenGL debugging! 😍 #gamedev

Over the holiday break I've been tinkering with #RenderDoc, trying to add D3D12 pixel history support. It's fun to see it starting to come together, though there's a lot still to test and fix. 😅
