Hi !<br>
<br>
I am following the mailing list - and more experienced with OpenGL
than when I wrote this plugin - but actually too busy the next
months to look into this or to add vertex shader support as
requested... Sorry !<br>
<br>
If you dont need realtime, maybe as a very ugly (and slow)
workaround you can try to gldownload ! glupload between shaders :-(<br>
<br>
Cheers,<br>
