All of this was rendering incredibly slowly, so I switched to an instanced rendering system.
This was also initially buggy, producing some strange images:

Shadows were finally working, and I also fixed specular lighting

I then enabled shadows. Initially my engine only supported Cascaded shadows, which is overkill for this.
I added a new 'Spotlight' shadow system, which only renders the scene to one depth texture.
I messed up some OpenGL calls which led to these strange glitches:

I then animated it appearing from the void below.
All these blocks were being rendered one at a time, which was very slow!
I changed to an instanced rendering system, which brought it up from 48 up to 560 FPS.

Here's a sneak peek of the animations for my next YouTube video on Raytraced Audio.
I'm using these wooden buildings to highlight issues with classic 'room-based' audio environments.
Check out the thread for the making-of:

It's not realistic but they also look great underwater.
I'll definitely need to add some underwater vegetation next

New sunset colours and shadows.
Before the world was going completely dark at the same time the sun set, when in reality that doesn't happen until after sunset.

Here's another mind bending animation about how 3D rendering works (it's all an illusion)

Performance is decent, the whole bloom process takes 0.4ms on a 3440x1440px screen with my RTX 3070.
Using a forward renderer (no more deferred rendering!) and the improved shadows from my last post, I’m at around 370 FPS on average

Previously I used separate gColour and gBloom buffers and only wrote to gBloom if I wanted bloom applied to that part of the screen.
I changed it to use one HDR gColour buffer like in this article: learnopengl.com/Guest-Articl...

It uses a HDR colour buffer, which can store colours greater than 255. If a colour is 300 or brighter, it is extracted into a separate buffer, then downsampled 8 times and upsampled 8 times
When applied to the scene at 10% strength, metal surfaces are nice and shiny:

After spending 7 years learning OpenGL, I finally have stable shadows. No more flickering!
Shadows and clip/light/view space have always confused me. And they still do.

Block select is so useful. Use Shift + Alt to select multiple lines, then Home, End and Ctrl + Arrow Keys to navigate left and right.
This refactor would take so long without it!

The TextureUnitHelper just keeps track of a counter that resets when a shader is bound, to ensure two different textures / sampler types aren't using the same texture unit.
Bindless textures would also solve this, but I'd like to maintain support for older GPUs

The best change is that textures are now bound at the same time uniforms are set.
This uniform class is the only time that glActiveTexture is called, which means uniforms and textures will never be out of sync.
