Hello community !
I start to write an help documentation (french langage) on the blenderclan forum, and after a while, i 
a bit:
what’s about the actuals plugins devlopment ?
some of them not working anymore and close blender imediatly !!!
some of them ask for: upgrade plugin, no float !
Thanks to answer me, anyway !
Bye
A great example of a modern plugin recently developed is the greenscreen sequence. See http://wiki.blender.org/index.php/Manual/Sequence_Plugins#GreenScreen_Plugin_Effect. That page also lists the known good ones; none of them crash.
The “Upgrade required, 32bit” message is just a warning; many times they will still work well. Yes, the old ones will not work anymore and may crash Blender.
Thanx papasmurf…as usual !
so the warning is not making any problem to use. most of them working well ! (after testing all today (more the greenscreen which is excellent !), some of them like the afterglow crach my computer ! is that true ?
will these plugins desepear in the futur with the ones are in the menu “Add” ? Do you know ? it’s look like !
