I recently discovered that when you want to add a font asset reference to the “bold typeface” field of another font asset, you cannot drag-and-drop the asset reference. This is because the Property Field is too small, and has been crushed down beyond its minimum width required for drag and drop interaction.
This is what the panel should look like in the more recent version of TMP.
Please make sure you are testing using the more recent version of the TMP package. The latest package release for Unity 2018.4 is version 1.5.0-preview.2. Preview 3 should be available over the weekend.
Thanks for the reply Stephen. Good to know that there is a fix in future versions.
Here’s some additional information about the problem.
I am running Unity 2018.4.0 (not the latest point release of 2018.4) on OSX. The TextMeshPro version experiencing this issue is 1.3.0.
I downloaded 1.5.0-preview 2 to test it out and see the following error in the console: Library/PackageCache/com.unity.textmeshpro@1.5.0-preview.2/Scripts/Editor/TMPro_FontAssetCreatorWindow.cs(11,19): error CS0234: The type or namespace name 'TextCore' does not exist in the namespace 'UnityEditor' (are you missing an assembly reference?)
