LineBatcher only draw 1 frame

Well. it seems that no matter what we do, our LineBatcher only draw one frame at a time, even though we supply it with positive life value.

LineBatcher->DrawLine(x1, x2, FColor::Red, 0, 1.0f);

Any clue how to fix this?

I, too, would like to know the answer to this.

Bump. I have the same issue
