Upgrading from V8.x to V9.x
Poiyomi Shaders received a plentiful of improvements and updates for 9.0. While most of everything may not look much different when compared to 8.0, it's worth noting that many areas have been significantly reorganized.
This page covers all the information you need to know when updating from 8.0 to 9.0.
Poiyomi 9.0 is specifically made to work with Unity 2022, as that is now the version required by VRChat. To see which specific version VRChat is using, please refer to their Creators Documentation.
Automatic Upgrade
Once you have installed the latest version of Poiyomi Shaders and are ready to upgrade your Materials from 8.x to 9.x, change the shader to .poiyomi/Poiyomi Toon or similar. You should see this Green Button appear in the UI. Press it to Apply the Upgrades.
This function will automatically convert any of your existing properties to be 9.0-compatible.
Do keep in mind not all will be converted perfectly, so we highly suggest you make a copy of your Materials before going forward with this.
Older Versions
All previous versions of Poiyomi Shaders are located underneath .poiyomi/Old Versions now. They are provided so that you can upgrade seamlessly.
Please do not use Old Versions for new Materials other than to upgrade them.
Important Changes from 8.x to 9.x
RGBA Color Masking
The entire Module has been redone completely from scratch, resulting in a better user interface and workflow.
Please take the time to go over everything if you use this feature.
Rim Lighting
The Rim Lighting Blend Mode Name was changed due to it having incompatibilities with lilToon naming. Therefore, the default mode may have been adjusted.
- IF Upgrading from 7.3: The Default was set to
Replace. - IF Upgrading from 8.1: The Default was set to
Add.
Matcaps
Matcaps have introduced Gradient as a new UV Mode, which works similarly to Iridescence. Use the Matcap Slot for your gradient texture, or click the wide-open field next to the slot to use Thry Gradient Editor to customize your own gradient.
Matcap AudioLink
For the first time ever, all Matcap slots now have AudioLink options available for you to use. This was added to accommodate those who are transitioning from using Iridescence.
Outlines
In previous versions, you would have to select a separate shader variant in order to use Outlines. This is no longer the case.
All Outlines features have been reintroduced to the main shader variant .poiyomi/Poiyomi Toon as of version 9.0.
Iridescence
Iridescence has been removed to save on compilation time. It has been replaced by Matcaps with the usage of the new Gradient UV Mode.
This is because Matcaps can technically do the same thing as Iridescence.
To compensate for this change, there are now 4 Matcap Modules for you to use. In addition, all AudioLink options that were available in Iridescence has been introduced to Matcaps.
Known Issues
Alpha Maps
You may have to re-assign your Alpha Map because the name was changed to better align with other Shaders. This may have been fixed already. But just in case it disappeared, simply re-assign the Alpha Map you were using.
Opaque Rendering
It's possible that a Material set to use Opaque may have "holes" in it after upgrading. To fix this, simply click the Rendering Preset dropdown and re-select Opaque.
