'HairRenderer' could not be found in 2023.1.0a7 (HDRP)

[Roland09]

When you import the project into 2023.1.0a7 (HDRP) these errors show up in the console:

Library\PackageCache\com.unity.demoteam.hair@7aa92e2cf9\Runtime\HairInstance.cs(84,12): error CS0246: The type or namespace name 'HairRenderer' could not be found (are you missing a using directive or an assembly reference?)

and

Library\PackageCache\com.unity.demoteam.hair@7aa92e2cf9\Runtime\HairInstance.cs(190,11): error CS0246: The type or namespace name 'HairRendererGroup' could not be found (are you missing a using directive or an assembly reference?)

It looks like the project does not recognize the scripting symbols. Double click on the error, you will see a conditional compilation line like this: `

if HAS_PACKAGE_UNITY_HDRP_15

Change it with this:

if !HAS_PACKAGE_UNITY_HDRP_15

` After changing the two errors you mentioned, you should see more errors but do the same thing until all errors are gone.

Same issue here with Unity 2023.1.0a6 It seems that HDRP 15 doesn't include any HairRender and/or HairRendererGroup class.

Follow the instructions by @bacimen and it should work.

Thanks for the answer. This should indeed fix the issue by excluding the HairRenderer and HairRendererGroup variables and references but I would like to try the high quality strands using the upcoming compute-based HDRP hair renderer [ depends on Unity >= 2023.1 ] mentionned in com.unity.demoteam.hair. Does this workaround enables this feature ?
