For DEM as displacement texture, I have no error.

Did you try to reexport the tif to a new one with QGIS or GDAL? sometime it can help. Can you share the file for testing it on my side?

[Rob-Lop]

Yes, it works with QGIS and I can open the file after doing an export. BlenderGIS could open any kind of GeoTiff files or are there certain cases where this does not work ?

[domlysz]

Tiff is a very versatile container, it's not surprising that some files does not work depending of the option used to it's creation. Should be useful to have a list of non supported options.

Hi there. I am having this same issue. Was this ever resolved? I'm assuming there's an issue with the format of my geotiff. Does anyone know of any guidance notes on the format of the geotiff for input to BlenderGIS?

Have the same problem with a jpg DEM. It worked with the previous one but reexported it in ArcGIS Pro in highr resolution. Now I get the bitmap load error when trying to import as displacement texture in BlenderGIS. Was this ever resolved?

I have the same problem. I exported from ArcGisPro. When I try to import with the gis plugin it looks like this I tried to export as 16Bit unasigned but only get a black output. Any ideas how to export from ArcGisPro so I can import it correctly with the blender plugin!?! Any solution is welcome :)

确保CRS为WGS 84 / Pseudo-Mercator，我使用QGIS导出，得到正常结果。

确保使用可正常识别的坐标系（CRS),比如：“EPSG:3857 - WGS 84 / Pseudo-Mercator”。这可能会有用。但我使用arcgis10.5导出仍然会报错，QGIS则不会。
