Weird behavior when showing WMS layers in 2.20

[mattiatibu]

Hi, I’m using ol-cesium to add some layers to a map but in the 3d view the WMS layers don’t appear.
I’m using Angular 17 and ol-cesium 2.20

The map projection is the default epsg:3857 and the layers are in epsg:4326, so they are reprojected by openlayers, it worked very well while using ol-cesium 2.19.3 but the layers don’t appear correctly or don’t appear at all after updating ol-cesium because the library tries to obtain tiles with the wrong bounding box from geoserver. It happens with WMS layers with the geoserver default style, a custom style configured in geoserver or just raster tilesets.

I've found a workaround , by changing the projection of my layer to EPSG:3857 in the openlayers layer configuration, the layer appears correctly and the bounding box requested is right but I still need layers in EPSG:4326 for my project, is there a better solution to solve this issue?

Hi @mattiatibu , there were some changes lately in the way WMS are loaded.
In the past we only supported converting WMS using default load functions.
See #1190
It is possible to specify the load function you want used in 3D. You may want to experiment with it.
