Thin point cloud problem

Thin point cloud problem


I am evaluating UdStream and I have run into two problems. I want to create a fly-through video in the point cloud environment. Unfortunately, during navigation in the point cloud, other floors are visible while points closer to the camera are thin and transparent. I tried changing settings but with no effect. 

This is an example area in Recap.

This is the same area in UdStream. As you can see, the points creating the interior walls are decimated for the sake of the exterior walls.

Second problem: while being on the ground floor I can see the basement. I don’t want to remove it completely because I want to make a smooth transition between levels later.

I will be grateful for any tips on how to make UdStream work differently.
