<p>Hey Rob!</p>
<p>I guess I read David say somewhere that this frustrating color problem was an issue with the current release of rhinoCommon, so I came up with a quick and dirty hack for the time being.</p>
<p>The trick is to make a new mesh and replace its normals with the color from the old mesh, and then evaluate that. It will make an invalid mesh, but will do its job for this purpose with no problem.</p>
<p>Check the attachment.</p>
<p>Cheers.</p>

<p>Hi David,</p>
<p></p>
<p>any chance you could fix this in a future release? my rhino still crashes on some cases. couldnt really find out what the driving factor for failure is.</p>
<p></p>
<p>in another case the mesh eval just gave wrong results it seemed.</p>
<p></p>
<p>see attached file!</p>
<p></p>
<p>thanks a lot,</p>

<p>another thing regarding the eval Mesh component - the color output yields null for my colored mesh, the others work fine.</p>
<p></p>
<p>both for my karamba mesh, as well as an arbitrarily coloured mesh plane.</p>

<p>Hi David,</p>
<p></p>
<p>this seems to be broken for unwelded meshes, I just forgot to tell until I tried again today.</p>
<p></p>
<p>Rhino crashes with a 'Send Error Report' Message, nothing else, as soon as I plug in the parameter into the eval component.</p>
<p>If I weld the mesh before, it works.</p>
