This short post by Defold people about "empty project build size" comparison between Defold, Unity and Godot (twitter, mastodon) sparked my interest.

It is curious that Godot builds seem to be larger than Unity? Would not have expected that! Anyway.

A way more extensive Unity "web" build comparison and analysics is over at https://github.com/JohannesDeml/UnityWebGL-LoadingTest but here are just my short notes in trying out Unity 6 (6.0.23 - Oct 2024).

Default (3D, URP) template

As per gfx-rs/gfx#3716 (comment) :

macOS has a system shader cache at $(getconf DARWIN_USER_CACHE_DIR)/com.apple.metal

On my MacBookPro that is under /var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C

• System shaders: /var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C/com.apple.metal
• Blender shaders: /var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C/org.blenderfoundation

Delete all the folders in there to clear the cache.

Windows

OIIO build instructions currently just say this for Windows:

Method 1 - from source I really need someone to write correct, modern docs about how to build from source on Windows.

So I decided to figure that out.

Easiest: get Blender first :)

// Quick try at doing a "print value" node for Unity ShaderGraph.
// Tested on Unity 2019.2.17 with ShaderGraph 6.9.2.
//
// Use with CustomFunction node, with two inputs:
// - Vector1 Value, the value to display,
// - Vector2 UV, the UVs of area to display at.
// And one output:
// - Vector4 Color, the color.
// Function name is DoDebug.
