Combine Mixamo Animations in Your Browser — Free Mixamo Alternative

ActionForge now supports animation layers directly in your browser. This update introduces a new timeline editor built for composing motion. By stacking clips, you can now blend movements, apply bone masks to isolate specific body parts, and fade transitions using simple drag handles—all without ever touching a keyframe. This update is designed to speed up character animation workflows for game developers and artists using browser-based tools. Whether you need to combine a jump with an aim motion or adjust posture on the fly, ActionForge allows you to preview, layer, and export your final sequence directly to your engine of choice. In this video I start with a backflip, then blend a bow aim onto the upper body only so the legs keep jumping. I arch the chest mid-jump with an adjust layer, add a shooting motion before landing, tweak the pose with IK, and export the result as a single animation. WHAT'S NEW IN THIS UPDATE Strips timeline — drag and drop animations onto stacked layers Bone masking — apply a layer to the upper body only, exclude the legs Blend handles — fade each layer in and out, no keyframing required Adjust layers — pose tweaks that only apply over the range you choose IK layers — IK edits become their own blendable strip Per-layer influence — dial back how much a layer contributes Mute (M) and Solo (S) — audition layers without deleting them Multi-select and delete — move or remove several strips at once Auto / Manual frame range Share links — send your composite to anyone, no account needed WHY STRIPS Before this update, any adjustment applied to the whole clip. If you wanted a character to aim a bow only while jumping, there was no way to say "just for these frames". Strips fix that. Each layer has its own range, its own blend, and its own bone mask, so you can combine animations the way an editor combines clips — without touching a single keyframe. WHO IT'S FOR Game developers who need custom character animations but don't want to animate from scratch. Anyone using free animation libraries who's hit the limit of what a single clip can do. Export to Blender, Unreal, Unity or Godot when you're finished.
