vents problem

[budd]

hi all, i've got a question - I have a set of vertical vents on the roof of a building, but when i render far away the vents go like this

but when i'm zoomed in they look fine with no distortions
like this:

- and the shader is a standard solid colour, no textures etc..
i've tried subdividing the surface and also extruding the top planes slightly but am a bit stuck, anyone got any suggestions?

hi
you may want to adjust your Dist thresh ... try 0.5.. or something like that... try to refine your sample's and increase your AA to 1.. / ..3 see if that helps..

cheers Natty (again! ) you've got me on the right tracks, I'll start having a little play about
