While compiling job:


It cuts off there.

The Package Manager thinks it’s successfully installed. All dependencies are installed and enabled.

On clicking Muse → Chat:

Also, is my trial period being wasted while I try to resolve this? Feels pretty unfair to start that timer before the installation is even verified to work.

Unity 2023.2 is not supported as it is missing some required API that are part of 2022 LTS and Unity 6.

Sorry for the inconvenience. I will ask about what we can do for your trial!

Thanks for the heads up. Where can I find the list of supported versions? I didn’t see one.

Hey - thanks for the feedback! It’s a good idea to publish our supported Unity versions - I will escalate this with the engineering team to find a good place to list these .

I’ll send you a DM about the trial. :email:

attempted to install w 2022.3.22.f1
got an error saying muse is not compatible before 2022.3.19f1 or after 2022.3.26f1

attempted to install w 2022.3.6f1
seemed to install but muse not appearing in menu
console error says
Library\PackageCache\com.unity.muse.chat@1.0.0-pre.10\Editor\Scripts\MessageUtils.cs(378,47): error CS0117: ‘AssetDatabase’ does not contain a definition for ‘GetMainAssetTypeFromGUID’

a list of compatible versions would be handy

Muse is being replaced with Unity AI and all Muse experimental packages are now sunset. Read more about Unity AI here: Unity AI: AI Game Development Tools & RT3D Software | Unity
