We have been generating a fair few 3D fly through videos of our city and whilst being a very effective way of communicating the information, there is something that happens which detracts from the experience for our viewers.
When exporting a 3D animation to a file, the renderer seems to generalise the DEM after what appears to be around 500(ish) metres away from the camera. I understand that this is likely a design decision to allow performance when rendering, but having the ground reshape itself as you move around isn't a very good look on a pre-rendered video!
Ideally, having an option/tick box that allows us to accept terrible performance when rendering (or a slide bar for distance) but drawing the DEM in full would be very handy. Perhaps then once ticked, each frame can be allowed to fully render prior to it being saved to the export file. Yes, it will take forever to run through the model and save it, but this can be run over night and would be fine.
