(I've moved this to bugs, I believe it's a bug).

Additive animations with weight 0 are still applied because of this line in egModel.cpp:

Code:

// Ignore stages with a blend weight near zero
if( curStage.blendWeight < 0.0001f && !curStage.additive ) continue;

I changed this to:

Code:

if( curStage.blendWeight < 0.0001f ) continue;

I don't understand why that condition was there.

Actually it is not a bug but was done deliberately. The weight determines the importance of the stage relative to other stages for interpolation/blending. Additive animations are just added on top of the rest, without any scaling with the weight factor. But there is no strong argument that it was done like this. If it makes sense it could be changed, will have to reflect about that a bit.

You got one vote in support of weight options to additive animations.
