<p>I've fixed it by recomputing, then unifying the normals. You can recompute normals by baking the mesh the running the rhino command "rebuildmesh"</p>
<p></p>
<p>Or in C# script editor you can make a little component to do it:</p>
<p>mesh.Normals.ComputeNormals();<br></br> mesh.FaceNormals.ComputeFaceNormals();</p>
<p></p>

<p>I made a Rebuild Mesh component which has a bunch of mesh options I found useful for cleaning this stuff. Try it out to see if it works. (the first option on the component is rebuild normals)</p>

<p>If I use rotate instead of mirror, which in my case works, as the front and back is the same, so i can rotate them 180 degress "front to back", then everything works as expected and it renders fine.</p>
<p></p>
<p>So mirror is definetly at fault here.</p>

<p>If I bake and click and drag to select a mirrored and unmirrored one, it shows as "2 closed meshes" though?</p>
<p></p>
<p>It seems like its messing up the geometry though. Do you know how to correct the geometry issue? Like is there a flip UV command in GH? I couldn't find anything..</p>

<p>My suspicions are that you have twice the geometry on the mirrored ones, but I cannot tell by pictures alone. Although that last shot would suggest my theory is correct</p>

<p>Oh hey again Danny.</p>
<p></p>
<p>The definition of the cull pattern? Its just based on largen than and smaller than of a list of values.</p>
<p></p>
<p>I just baked everything though and it looks like the actual geometry gets mangled when mirroring. Was thinking before that when mirroring maybe UVs get flipped too? like being turned inside out?</p>
