You have created a DSM with Drone2Map.
CityEngine does support import of image based terrain data.
Please follow the steps to create a Terrain Layer in CityEngine Help.
If you want to add 3D data from Drone2Map,
I suggest georeferencing the drone2map OBJs or FBXes in CityEngine.
1. use your DSM or "File > Get Map Data..." to download the surveyed area
2. import the drone2map export as static model (drag file into scene)
3. use the translation tool to fit the model into the map
CityEngine does not support import of SLPKs.
I have been able to get the two imported into CityEngine, but the Terrain and Texture keep appearing way above the grid in CityEngine. How do I move everything down to match?
Maybe LR is referring to turning off Value filtering in the Inspector as in these other posts:
Value filtering is briefly described on this help page (in the table near the bottom):
Here is the description from the page:
The filtering applied to terrain height and sampling. Choice of either none (pixelated), or smooth (linear) filtering.
