Draping imagery in ArcScene

Question

I am working in ArcScene 10.3 trying to drape a MrSID image over a DEM.  It is not draping properly (the two layers overlap instead of SID appearing on top) and when I add vertical exaggeration it is different for each layer (the DEM appears to float above the SID image).

I believe your DEM has course resolution compare to SID. It happens because SID image is draped on the DEM.

Thank you for response.

Turns out I needed to reproject the SID to match the data frame.

However, my SID image resolution is greatly diminished.  Can I improve it?

* In the table of content keep the SID on top of DEM
* Right click on the DEM > Properties >Base height > Floating on a custom surface = DEM
* Right click on the SID > Properties > Base height > Floating on a custom surface = DEM
* Scene properties > Vertical exaggeration > Calculate from the extent or set it manually.
* Right click on the DEM and Zoom to layer.

Hope above steps are helpful.
