Manual

System requirements

To use Bakery you'll need:

• Windows (7 or higher) PC.
• Nvidia GPU. Minimum supported model is Kepler (GeForce 6xx or newer. For Quadro cards check the specs).
• 64-bit Unity editor. Bakery was tested on all versions from 5.6 to 2019.1.

Prerequisites

• Make sure your project does not have any script compilation errors, as it will prevent Bakery scripts from compiling as well.
• Make sure you have the latest GPU driver. Update it if needed.

Installation

1. Import Bakery to your project via Asset Store.

2. Unity will show a list of files to import. If it's your first time using Bakery, it is recommended you just click Import. Experienced users may want to untick the examples folder for a more lightweight installation.

3. Unity will then import Bakery and compile the scripts. It may show a window like this:

In which case you should click "Go Ahead".

You should now see Bakery menu added to the editor:

Quickstart

1. Add some model or primitive and mark it as Static.

2. Select Directional Light (the one Unity created for you) and add Bakery Direct Light component to it.

Bakery and Unity use separate light source components.

3. Bakery Direct Light has many options to tweak, but you can easily match it to Unity light. Click Match lightmapped to real-time. Now Bakery light should have the same yellowish color as Unity’s default Directional.

Direct Light component may complain about project not using linear light intensity. The problem is that by default Unity applies gamma correction to light source colors incorrectly. Correct mode can be enabled by scripting, and that’s what the “Fix” button does. If you already have many light sources set up in non-linear intensity mode, and you don’t want to change them again, you may skip fixing. Even if you press “Fix”, you can always revert the change anytime.

4. To get shadowed ambient lighting, create Skylight (Bakery->Create->Skylight).

5. Select Skylight, give it some bluish color and click Match scene skybox to this light. This will make scene skybox match lighting exactly.

Matching Unity skybox to Bakery skylight is optional but useful for correctness, as to ensure that visible environment and in-engine reflection probes match baked lighting.

6. Click Bakery->Render Lightmap. By default, Full Lighting mode is active. It will bake both direct and indirect contribution from all lights. If you want to combine real-time shadows with baked GI, change it to Indirect.

Bakery may complain that you are using old gamma mode and suggest to change it. If you care about quality of lighting, using Linear mode is highly recommended. You may ignore it if you already have a big project set up with incorrect gamma and don’t want to change it or when shipping to mobile devices that don't support it.

7. Click Render.

8. Done! You should now have baked GI:

Render settings

All render settings can be accessed via Bakery->Render Lightmap. Settings are saved for every scene. The topmost option in Bakery window allows you to switch between Simple, Advanced and Experimental settings, each succeeding mode revealing more tweakable options. Simple mode is enough for most scenes and a good way to get started.
