Hello,
I am having trouble loading in bathymetry tiles into unreal. I think the tiles themselves are correct, but all the tiles load in completely white. Is this a material issue, and how can I fix this?
Also I have both the bathymetry and the Cesium World tiles loaded as having the coast is a nice visualization. Is there a way to only get the underwater bathymetry part of the bathymetry tiles, and not the parts that go onto land.
Currently, the tiles are completely white as they don’t have a raster overlay. If you’ll look on your Cesium World Terrain tiles, there’s probably a CesiumIonRasterOverlay attached which layers satellite imagery over the terrain, which is itself blank and textureless. You can attach a new overlay to the Bathymetry dataset to give it a texture by adding a new component. You can add a Cesium Ion Raster Overlay and specify an asset ID, or you can add a Tile Map Service, Web Map Service, or Web Map Tile Service overlay to use an external source.
For example, you can add a CesiumWebMapServiceRasterOverlay and set the Base Url field to https://wms.gebco.net/mapserv? and the Layers field to GEBCO_Latest which will overlay the GEBCO shaded relief imagery over Cesium World Bathymetry.
Hi, I’m finding these instructions a little difficult to get working. Could someone do a quick demo or something? I guess I’m doing something wrong..thanks
Hi, TheExcelExperts,
1. Add a CesiumWebMapServiceRasterOverlay component to the terrain’s Cesium3DTileset actor.
2. the Base URL is set to https://wms.gebco.net/mapserv?
3. The Layers can be set to the following values for GEBCO_2024 Grid - with ice surface elevation information:
(1) gebco_latest: the global GEBCO Grid displayed as a shaded relief image
(2) gebco_latest_2: the global GEBCO Grid displayed as a ‘flat map’ image, colour-coded for elevation
(3) gebco_latest_3: the global GEBCO Grid displayed as a ‘flat map’ image, colour-coded for elevation, showing areas based on measured data only
There are other WMS layers on the GEBCO WMS | GEBCO website. You can just click the GetMap link and find the Base URL and Layers for CesiumWebMapServiceRasterOverlay in the http URL displayed in the web browser.
thats great thank you
Having this problem with wanting bathymetry and cesium world terrain on the same image. DId you find a solution?
