I got a Unity error after I try to add my own 3DTileset from a local directory

Cesium for Unity
1

Hi my friend,I have tried to add a 3D Tileset from my PC local directory,but I got an error on the unity console window

NullReferenceException: Object reference not set to an instance of an object
Reinterop.ReinteropInitializer.System_Collections_Generic_Dictionary5Hx6c0Eu2sl__zevLSSpjKA_CallGetEnumerator_1B2M2Y8AsgTpgAmY7PhCfg (System.IntPtr thiz) (at Library/PackageCache/com.cesium.unity@0.3.0/Runtime/generated/Reinterop/Reinterop.RoslynSourceGenerator/ReinteropInitializer.cs:32197)

UnityEngine.AsyncOperation.InvokeCompletionEvent () (at <28d694a2939e4826992577f826717d3b>:0)

I have tried to fix this problem myself and I found that if I change the cesium-unity-samples-0.2.0 project’s second scene Melbourne Photogrammetry’s URL to my 3DTileset local directory url,I won’t get the error.
Please help me figure out if I set something wrong.
Think you all.

How did you create the new tileset? Did you use the “Cesium” panel to add a blank tileset? Or did you create it manually? My best guess it that perhaps your new tileset isn’t nested inside a CesiumGeoreference?

Hello @Kevin_Ring ,Thank you for your reply.
I’m sure I used the Cesium panel to add a blank tileset,and the new tileset is nested inside the CesiumGeoreference,please check out my screen recording below.

Hi @Kevin_Ring ,I’m still trying to fix this issue.
I tried to changed the version of cesium for unity plugin to 0.2.0,it helps.
I used 0.3.0 then I have this issue,maybe new version has some problem.
Best wishes.

Hi @Ember6489,

I confirmed I’m seeing the same issue with Cesium for Unity 0.3.0 as well. I’ve opened an issue on Github to track this bug. Thank you for the report!
