We’re experiencing corrupted/incorrect terrain texture rendering in Unreal Engine 5.4 using the Marketplace version of the Cesium for Unreal plugin. The issue is present even when using the official ‘Cesium for Unreal Samples’ project. The terrain geometry loads, but textures are applied incorrectly (appearing corrupted or out of order).
This problem does not occur in Unreal Engine 5.5 with that version of the plugin. However, we are currently dependent on Unreal Engine 5.4 due to DLSS requirements.
Hi,
I just tried a clean copy of the Cesium for Unreal Samples project in UE v5.4.4, with the Cesium for Unreal plugin (v2.13.2) installed from the Epic Launcher. I don’t see that texture smearing problem in your screenshot.
Is it possible you’ve (perhaps inadvertently) modified something in the plugin, such as one of the materials? I could be worth uninstalling and reinstalling the plugin.
Or maybe you’ve changed some setting in Unreal Engine itself?
Or maybe it’s a hardware incompatibility? What sort of system are you running on? Are you able to reproduce this problem on any other systems?
- I’m running the Marketplace plugin for 5.4, in conjunction with the Cesium for Unreal Samples project vanilla, nothing else is modified. Editor has no other plugins active. Project opens with terrain imagery displaying incorrectly.
- Cleared Zen cache.
- Not hardware, used Cesium successfully previously with Self Hosted. i9-13900, 4090, 128GB RAM.
- Tested on another machine, displays correctly.
What could be affecting this?
Can you please try uninstalling the plugin using the Epic Launcher, then delete C:\Program Files\Epic Games\UE_5.4\Engine\Plugins\Marketplace\CesiumForUnreal_5.4 (if it still exists after uninstalling), and then reinstall it. Some sort of corruption of a Cesium material seems the most likely explanation. Or at least, I’m struggling to think of another one!
