X-Muscle System

by k44dev Software in Scripts and Addons

X-Muscle System is advanced, physics based tissue simulator for Blender.

What is X-Muscle System?

X-Muscle System is an add-on designed for rapid muscular system, tissue and other organic object creation and their physical simulations. Its main purpose is to help visualize better skin surface deformations according to volume preservation of the body muscles, fat and even skeletal bones. Add-on lets you focus on the design, creativity and to significantly speed up the workflow with extremal learning curve. 

With X-Muscle System an artist is free to focus on the artwork and use effectively his time to create even more realistic, complex shapes and animations of characters and creatures. With its simplicity and integration with Blender's native tools, X-Muscle System is powerful, easy in use and ready to start straightaway. X-Muscle System has been designed and written from the scratch and completed with the functionality you always wanted.

Build high quality, realistic muscle structures with ease

Thanks to flexor and extensor muscle types creating biceps and triceps for your character was never that easy.


Work smart and fast - X-Mirror with single click

With powerful X-Mirror option there's no need to duplicate work. X-Mirror will guarantee excellent symmetry for tissue's shape, properties and behavior saving your effort and time.


Achieve the most complex shapes with Muscle Pinning and Bendy Muscles

Now, with muscle pinning and bendy muscles, tissue shape will follow the bone chain of your rig. Thanks to that, you can create the most advanced and realistic muscular systems.


Inspect your character with provided tools

X-Muscle System provides dedicated Display Tools which allows to work and inspect with ease.


Improve all your existing scenes with the dramatic touch of realism

X-Muscle System works straight away and does not require any preconditions or additional setup so you can start adding great visual experience without reordering your scene.


Start your work with Anatomy Bundle

X-Muscle System comes with rigged human male skeleton model which allows you to immediately exercise your skills.


Bring your digital art back to life!

  • dog
  • horse
  • human male V1 and V2

Standard add-on version includes one rigged model - human male V1 skeleton

I already have X-Muscle System Standard, can I upgrade to XL variant?

Yes, for upgrading the add-on contact X-Muscle System support and Blender Market team.

What license is the skeleton model?

All skeleton models are included under Royalty Free License

I made a purchase some time ago but I can not update the add-on because I don't have an account!

In this case please contact Blender Market support. They will help you and instruct step by step how to download the updated files.

I want to update! Where are the files?!

Each new version is available for download on Blender Market. Old files are always replaced by new ones. To download the update all you have to do is to download the same files. Add-on as well as documentation are always versioned so if you have any doubts just look for the version numbers in downloaded files.

What is the difference between Blender Muscle Tools and X-Muscle System?

X-Muscle System is advanced system for creating character's musculature. It includes multiple automation tools, which can not be find in Muscle Tools. Making the rigging time down from days to minutes allows to focus only on the creative part of the work. The most important exclusive features X-Muscle System provides:

  • Advanced and intelligent X-Mirror
  • autobind feature
  • auto-weight paint feature
  • powerful renaming system
  • multiple muscles control system 
  • easy switch from flexor to extensor muscle type
  • intelligent dynamics cache update
  • intelligent Vertex-Groups Manager
  • intelligent modifiers and drivers management
  • designed for freestyle workflow (symmetrical pose is not required)
  • micro skin Controllers which improves deformation quality and precision
  • supports mesh models with shape-keys and drivers
  • muscle pinning with x-mirror support
  • anatomy bundle included
How long I will receive new updates?

X-Muscle System customers will be supported for the whole product life-time with all the documentation, video-tutorials, software updates, new features and bug fixes. All future updates and new content are free.

Can X-Muscle System export its muscular system for game engines like Unity or Unreal Engine?

At the moment there are three ways of exporting character's mesh with muscle deformations. First of them is NewTek MDD exporter, which will export shape-keyed animation keyframes. The second one is done via Corrective shape keys. This second method allows to control specific muscle behavior within game engine via bone-driven shape-keys. Both add-ons are provided with blender and need activation in User Preferences. Third one is done by baking displacement map.

Is Blender Muscle Tools the same as X-Muscle System?

No, Muscle Tools and X-Muscle System are not the same products. They're different projects and they're not even compatible.
