X-Muscle System 4.0

by k44dev Software in Addons

Will it work with old Blender 2.8?

Starting with 2023 X-Muscle System support for older Blender versions than 3.X has been dropped. The add-on gets support for its product life-time and the latest Blender it supports is 4.X.

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.

Also Alembic with its pros and cons can be used.

What is X-Muscle System XL variant?

X-Muscle System XL variant is deluxe edition of the add-on including high quality Anatomy Bundle rigged models and Exclusive Early Access to Beta Features.

Current Anatomy Bundle content:

  • cat
  • dog
  • horse

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.

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.

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.

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.

My skeleton model is responding very slow when I move it.

Each model has Subsurf modifier enabled by default. Disable the Subsurf for the Viewport in Modifier's section or use the Simplify in the Scene section to simplify the whole scene.

I want more freedom in movement of my model!

Some control bones transformation may be limited by default. If you want more elasticity of your model just unlock transform for Loc Rot or Scale for particular control bones.
