Blend shapes - Multiply/divide the results without changing the weight value?

#1

Hello guys,

As you know, if I created a blend shape and for example put 2 in the blendShape weight attribute, it will multiply the end result by 2.
The question is, how I can multiply/divide the result without changing the blendShape weight attribute?

It sounds stupid, but I need this function, because I have automation system just takes a range of (0-1) from the weight attribute.

Any idea guys?

Thank you in advance.

You can make a copy of the result (with weight 2 or what ever) then delete the blendshape and make it again with the new target.

Have you tried setting the Envelope on the Blendshape node to 2?
It depends on your shapes but usually this works as a good multiplier for most blends.
fingers crossed.

Hi!

Its very simple with a expression as the connection between the two.
If your controllers name and attribut for the blendshape is:
masterBlendController.blendvalue

And the name of the blendshape node and attribut is:
blendshape1.shape1

Then you can combine them two and just multiple by one.

blendshape1.shape1 = masterBlendController.blendvalue * 2;

See my point?:slight_smile:
