Graphic Issues with Large Models

I am trying to use Rhino to show the view from a room to a mountain range. I have imported a mesh from a DEM file and have nice landscape BUT when I position a rhino camera in the room I cannot see all of the landscape and sometimes the walls are missing. I just need a shaded screenshot showing the mountain through a specific window. Is there a setting I can change? I’ve already tried to increase the rhino mesh display from “jagged” to “smooth”.

If you alt+scroll to zoom doss that help-

thank you for the advice but it doesn’t really help. Sometimes it works slightly better but other times it just glitches and has the same issues.

The size of the z-buffer has been stretched too far. Video cards sort objects into depth layers. There are a limited number of these layers. So if something is large and one piece, but you are concerned with a view that needs depth accuracy to properly hide in small area, there are problems. To test this try and hide the landscape. Do a zoom extents and see if the hide comes back properly. In the past I have fixed this by breaking up the landscape into parts. This can allow better sorting. Or for a rendering, render the landscape from the view and them use that rendering as a backdrop.

Thanks Scott, this sounds exactly like the issue. I didn’t realize it had a name! I will test this later and see if I can reproduce what you are explaining here. Do you think a newer and fancier graphics card will solve the issue? I have a work computer with more horsepower that I can VPN into to test this


Hello - I would test before buying… I am not 100% convinced yet that it is due to the number of depth sorting slices… it looks like the camera near clipping plane is too far forward - the cause may be the same I don’t know, but I would try hiding as much of the scene that is behind the camera as possible - preferably everything, even if just as a temporary troubleshooting measure, any of the landscape mesh that is outside the camera view - does that make any difference?
