Bug Shader error in 'TextMeshPro/Mobile/Distance Field': Couldn't open include file 'TMPro_Properties.cg

This error is usually the result of some importer issue where the .cginc file gets messed. As you have done previously, re-importing the TMP Essential Resources or just the shaders themselves will resolve this issue.

What version of the TMP package are you using?

Note that the location of the TMP shaders has changed over the years where the shaders used to be located in "TextMesh Pro/Resources/Shaders/...." and are now located in "TextMesh Pro/Shaders/...".

Please make sure that all of your TMP shaders are located in this folder as well as the .cginc file.

It is possible that somehow, you have some shaders located in a different location where they would not be able to located this .cginc file.

Let me know if you do find that you have some TMP shaders perhaps contained in some other location in the project and if any of the above has helped you resolve your issue.

 

Do you still get the error on the mobile shader or still on both "TextMeshPro/Mobile/Distance Field" and "TextMeshPro/Distance Field"?

What happens if you manually re-import the "TMPro_Properties.cginc" file?

Can you search the project to see if there are perhaps other versions of those shaders in other folders? Maybe a duplicate somewhere?

What happens if you create a new project and import the TMP Essential Resources? Do you still get those errors?

 

The above error is either the result of a corrupted "TMPro_Properties.cginc" or the shader compiler being unable to locate this file perhaps because the shaders that are referencing this file have been moved.

Note that TMP Shaders used to be located in "Assets/TextMesh Pro/Resources/Shaders" but were moved several releases ago to "Assets/TextMesh Pro/Shaders" to avoid having every shader always included in builds.

Can you look through your project and report the location of the TMP shaders.

Here is a screenshot of these shader files which should be located in "Assets/TextMesh Pro/Shaders" along with this "TMPro_Properties.cginc" as seen below.



Maybe this behavior is the result of having these shaders split between these different locations but the "TMPro_Properties.cginc" only being present in one of them. If that is the case, please move all shaders in the above location as per the screen shot.
