Hi,
what is the difference between additive animations and blending animations ?
thanks
Hey phil123456,
Additive animations are used to blend animations. When two animations are added together, the average of both is kept as the final result, depending on the weight assigned to each animation. Picture an animation of a person walking upright, and another animation of that same person but bent over at the waist. If these are added together, you will be left with an animation of the person walking over and bent at the waist. Animations can be blended by weight and can be managed by blendspaces which allow you to determine when and how to blend animations automatically.
I highly recommend you look further into Animation Blueprints and blendspaces, as they will be very important to many Unreal projects. You can read more about layered animations here.
I hope this answers your question!

I know blendspaces and mixing anims but I dont understand why is there additive animations
I can do the same with blend nodes so… I just dont get it
A blend occurs to the current state as to what has come before and after. UE4 calculates a number of frames into and out of the current state so that the final result blends instead of the animation popping between state changes.
As a practical application an additive pose can be used as a corrective pose so lets say your base animations uses a rifle by default. Using an additive you can use the rifle base idle, usually aiming forward, with the aim forward of the player holding a sidearm as the additive with in the migration stream and all of your animations will adjust to the sidearm and still make use of the rifles animations with out have to create a unique set.
Additive poses can and is confusing as it has a number of different applications.
