Simple Light Probe Placer
About
Simple Light Probe Placer it is simple tool for Unity3d
and it help you easily place Light Probes in your scene.
It's provides two new components: Light Probe Volume and Light Probe Group Control,
on which you can read below.

Light Probe Volume
Light Probe Volume it’s important part of Simple Light Probe Placer
and can help you easily place your probes all over the scene.
Provides simple volume (or bounding box) with density settings,
which you can use for determine where probes should be.
Create
You can create new instance, just using create menu on top of
Hierarchy tab or add new Light Probe Volume component to your
GameObject using Add Component menu.
 |
|
Path: Create > Light > Light Probe Volume |
 |
|
Path: Add Component > Rendering > Light Probe Volume |
After when you add in scene new Light Probe Volume, you should see this (without 3d gimzo).
Yellow squares it is handles for changing size of volume and small white squares
represents places in scene, where it will create Light Probe.
Note: If you want hide 3d gizmos see here.

Inspector

| Name |
Description |
| Volume |
Parameters for volume (or bounding box). |
| Origin |
Position of center of volume. |
| Size |
Size of volume. |
| Type |
Type of density, which can be: Fixed or Float. Possible values: Fixed 1-100, Float 0.1-50. |
| DensityX |
Control density by x axis. |
| DensityY |
Control density by y axis. |
| DensityZ |
Control density by z axis. |
Note: Volume parameters almost the same as in another components (like Collider).
You can manually change origin position and size.
Density
Light Probe Volume has two types of density: Fixed and Float.
 |
| Type of density. |
Fixed
Fixed density depend on how much it should divide space inside volume by specified axis
for placing probes. And density always will be fixed, regardless of volume size.
 |
| Example of different fixed density settings. |
 |
| Example of how is changing density with fixed type, depend on volume size. |
Float
Float density depend on distance between each probe in specified axis.
It will fills space inside volume, so density always will be float and will depend on volume size.
 |
| Example of different float density settings. |
 |
| Example of how is changing density with float type, depend on volume size. |
Light Probe Group Control
Light Probe Group Control is second part of Simple Light Probe Placer and controls Light Probe Group,
attached to the same GameObject. It will finds all Light Probe Volume and using them settings for creating
Light Probe positions, for future scene baking.
Note: Light Probe Group Control require Light Probe Group component.
Create
You can create new instance, just using create menu on top of
Hierarchy tab or add new Light Probe Group Control component to your
GameObject using Add Component menu.
Note: After add new Light Probe Group Control component, it will automatically add Light Probe Group to the same GameObject.
 |
|
Path: Create > Light > Light Probe Group Control |
 |
|
Path: Add Component > Rendering > Light Probe Group Control |
In scene it will looks like this (without 3d gimzo).
Note: If you want hide 3d gizmos see here.

| Name |
Description |
| Delete All Light Probes |
It will delete all Light Points positions in Light Probe Group attached to this GameObject. |
| Information |
Provides some information, about how many light probe position you have and how many positions was merged. |
| Create Light Probes |
Create probe positions using all Light Probe Volume found in scene and merge closest positions, depend on merge distance option. |
| Merge Closest Light Probes |
Merge closest positions depending on merge distance. |
| Merge distance |
The minimal distance between probe positions for merging. |
| Point Light Settings |
Provides settings for Point Lights. |
| Use Point Lights |
Determines whether it will use Light Points for creating probes positions. |
| Range |
Distance from Point Light for create probe positions around. |
Point Lights
Using this options, you can create Light Probes around Point Lights
and control distance to it, using Range option (see above in table).
 |
| How it’s look like in scene. |
 |
| Worked example. |
Example usage
It is example how it's worked. Scroll down to see steps.
 |
| Step 1: We have scene without any baked data. |
 |
| Step 2: Now we should place everywhere where it's need Light Probe Volume and set up size and density for each. |
Note: Don't forget add Light Probe Group Control.
 |
| Step 3: After you finish setup all Light Probe Volume, in Light Probe Group Control press a Create Light Probes button. |
 |
| Step 4: And finally bake you scene data. |
Also
If you have some problems with annoying 3d gizmos of all Light Probe Volume, it's help you.
It is very simple, on the top-right corner of Scene tab, will button with name Gizmos, here you
can find list of all gizmos for showing in Scene window. After open it, you should see something
similar with what shows in first column on image below and you can just press on icon of what you want to hide or show in Scene.
That's all and Good Luck!
