Crash accessing textureCoord2 on scene layer RaycastHit

Hi,

I'm encountering a crash when using Unity's `RaycastHit.textureCoord2` property exclusively when raycasting against scene layers.

Example:

RaycastHit hit; if (Physics.Raycast(rayOrigin, rayDirection, out hit)) { var texCoord2 = hit.textureCoord2; // Crash in textureCoord2 access }

Does anyone have experience with this issue and have any suggestions on how to avoid a crash while still being able to raycast against scene layers and access `textureCoord2` (in case the hit is not an ArcGIS scene layer and I do need to use `RaycastHit.textureCoord2` for other potential hits)?

Note: I suspect this could be related to the fact that scene layer meshes have feature indices in uv channel 1, which consist of a single float value rather than a `Vector2`.
