I was lucky enough to help playtest Rift Riff and I loved it.
It releases tomorrow, I’m keen for my third playthrough!

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:

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)

Check out these bloom effects
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!

Hundreds of errors in Visual Studio, we meet again!
After refactoring shaders to support hot reloading (which is awesome) I realised the way textures were bound to shaders wasn't great.
So now, I'm refactoring shaders... again...

Shader Hot Reloading is working!
If the current shader string is different to the last, the shader gets recreated and its uniforms are reconnected.
Also if the shader string is invalid (e.g. syntax error), it will revert to the last working shader.

The shader refactor is complete and the project is building again. Now it's time to fix all the runtime bugs 😅
The codebase is much leaner though:
157 files changed
4860 insertions
8485 deletions
Net: 3625 lines deleted

Working on a huge shader refactor today, with the goal of being able to hot reload shaders.
Each shader used to be two large strings (one for the fragment shader and one for the vertex shader), but now they are constructed from these 5 strings.
This keeps uniform and varying names consistent too!

Why can you hear sounds above + below you in games, when your headphones only have speakers on the left + right?

What do you think of these "Dissolving Triangle" animations?
I'd like the triangles to change to a wireframe view first, and then subtly shrink + fade out

Check out these raytraced audio animations
- White lines are the rays cast outwards from the player
- Blue lines are the reverb rays returning to the player
- Yellow lines are the rays that have discovered a sound source

Game devs constantly restart their game when working on it, and I found I was spending a lot of time waiting for my game to start up
