[Bf-committers] Weights range in vgroups

[Bastien Montagne]

Hi all,

Today on irc, Campbell pointed out an important point about current 
WeightVG modifiers code : they allow weights to be out of the standard 
[0.0, 1.0] range.

So the question is: does those modifiers have to clamp the weights to 
that range (which would reduce their flexibility and power), or do we 
accept that weights can have lower/higher values ?

This is obviously a quite important decision, which needs advices and 
thoughts from all blender devs. :)

As for me, IMHO, the later would be the best solution – if a piece of 
code really *needs* weights inside a given range, it’s easy to clamp 
them at that moment… It’s a bit like floating point rgb values, in 
pictures : it’s best to clamp them back to [0.0, 1.0] at the end, and do 
compositing with full ranged values!

Regards,
Bastien
