I took a screen snip of the node and blend mode in question. I have a blendshape in my skeletal mesh and would like to use this node to control my BS. It works fine with the default apply mode Blend.
My understanding of the WMA mode is that if I put a value 1 into the BS pin and 0.5 into the alpha, it would be 0.5 at the first frame, 0.75 at the second frame, 0.875 at the third frame, etc. Eventually, the weight should be infinitely close to 1. This would be an easy way to get a simple fade-in effect.
However, my test result is, when I use WMA mode, it doesn’t work at all. No matter the BS and alpha value, the BS simply doesn’t change.
My question is just how does it work? What’s it for? Can I get a simple example illustrating the function of this apply mode?
Hi I just encountered this and even aftet a year though it still doesn’t work. It is for example used in the Face AR Example where they use it to “denoise” the ARKit input but no matter what WMA param you set it doesn’t do anything. Is this intended? If so can anyone confirm that this changed and why since 4.20?
