I ran into a problem previously. There was a nice tweak to work. I was getting material artifacting if near clip was zero or to low. I left a issue of it at https://github.com/urho3d/Urho3D/issues/1920 and http://imgur.com/a/yyP7q
When I set the near clip of the camera to 1.0f it helped solve the problem. Ideally I would like to move the camera for example 1km from a object and still have it show visibly okay. At minimum a near clip of 0.1f or lower, to 8192km far clip. It might be a little extreme.
Ideally I would like to model objects full scale as 1.0 equal to 1 meter.
Any thoughts or help appreciated. As I’m not sure what internal Urho3D updates is needed to make that possible.
