Problems adding elevation data

Question

Hi everyone, I am just starting to use ArcGIS Pro, and I am trying to create a local scene.

I exported a DEM model from Agisoft Photoscan as a a GeoTiff Elevation Data. I also exported a high quality JPEG that I want to drape over the elevation data. The problem is that when I add the .tif as a elevation source it says "an elevation surface needs to contain supported elevation information and the data source needs to be accessible". The .tif displays fine as a raster, showing a black and white contrast image.

I assume it has something to do with how I export the DEM from Photoscan. I do not understand what the no-data value is, I tried it as -3.40282, I found that value on a different forum regarding ArcMap.

Any help would be appreciated, I am trying to figure things out as I go. Thank you

My ArcGIS Pro (v3.3.1) was telling me the same ("An elevation surface needs to contain supported elevation information and the data source needs to be accessible") when I tried to add a DEM raster as an elevation source in a Local Scene. It appeared OK as a 2D layer in the scene though.

I fixed it by defining spatial reference with the "Define Projection" GP tool.

Solved now, I just had to run the raster to tin tool, and use the tin file as an elevation source.

It is a 32 bit tiff. I tried that no data value, but now it doesn't work even as a raster image. Metsa2.tif is the one with -3.40282 value and that displays properly as a raster. Nothing works as an elevation source.
