Google 3DTiles do not cast shadows

AeliusDylan · May 11, 2023, 1:56am

Having fun playing with the Google 3DTiles in the world, but I noticed that dynamic shadowing doesn’t seem to work properly with it.

I tried plugin versions 1.25.1 and 1.26 on UE 5.0.3.

The Google 3D Tiles use the glTF “unlit” extension, because they already have lighting baked in. But you can ignore this and rendering them with UE lighting anyway by setting the “Ignore KHR_materials_unlit” property on the Cesium3DTileset.

@Kevin_Ring what would you suggest if the “Ignore KHR_materials_unlit” property on the Cesium3DTileset isn’t visible?

@bradshales It should be visible regardless of the Cesium3DTileset. The setting will appear under the Rendering menu.

If it doesn’t show up for you, maybe something is wrong with the UI in the plugin? Can you share the combination of Unreal Engine and Cesium versions you’re using?

Hi @janine , thanks for getting back to me. I’m using Cesium 1.22.0 and UE5.1.1. below is a screenshot of available settings. Any guidance on this would be greatly appreciated. Cheers.

The option was added in v1.24.0:

# Change Log

### ? - ?

##### Breaking Changes :mega:

- Removed the `GetGeoreferencedToEllipsoidCenteredTransform` and `GetEllipsoidCenteredToGeoreferencedTransform` methods from `GeoTransforms`. Because these were transformations between two right-handed coordinate systems, they are not of much use with Unreal's left-handed coordinate system.
- Deprecated the `FlyToGranularityDegrees` property for `AGlobeAwareDefaultPawn`. Flight interpolation is now computed per-frame, so this property is no longer needed. Any code that refers to `FlyToGranularityDegrees` should be removed or changed to `FlyToGranularityDegrees_DEPRECATED` to still compile.

##### Additions :tada:

- Added ability to set CesiumGeoreference Scale via Blueprints.

### v1.27.1 - 2023-06-19

##### Fixes :wrench:

- Fixed a shader compilation error introduced in v1.27.0 that prevented projects from opening in Unreal Engine 5.1 and 5.2.
- Fixed a debug assertion `!IsGarbageCollecting()` that could occur within `ACesiumCreditSystem` when flying to different sublevels.
