Hi, heres a simple povray exporter- I cant get the camera rotation working- see line 30-
file.write(' rotate <%s, %s, %s>
' % (euler[0]*-1, euler[1], euler[2]*-1))
Im interested in a simple povray exporter that dosent need to be configured like Povanim- just ‘Render my scene’!
I know its never that simple but I can be idealistic.
Problems I have-
*Smoothing (currently all smoothd)
*No vertex colour support in Povray???
*Generaly fiddling with converting matrix objects into povrays user friendly values.
Havent even looked at materials yet.
