I meant using the OGL preview shaders: http://groups.google.com/group/grasshopper3d/web/ColourPreview.png
I noticed there is a bug in the Planar-Surface->Plane conversion, I'll fix this for the next release (available hopefully sometime later today). Also, in the next release you'll be able to plug a colour directly into the Preview Component, no need to specifically create a shader first. -- David Rutten [email protected] Robert McNeel & Associates On Apr 10, 11:55 am, hypertriangleman <[email protected]> wrote: > I tried doing as you said, although there are still some issues that I > have resolved.
