Installation#

Download#

Get the Plugin on Fab.
Install it to your project or engine from the Epic Games Launcher in the Unreal Section. See the official documentation for details.

Setup in Engine#

Without this you cannot use Tab to toggle between the normal selection mode and the Blender mode.

This step is technically optional but recommended: Go to your Editor Preferences under Edit and search for “Viewport Context Menu”. Rebind the shortcut of “In-Viewport Context Menu” to Shift+Tab instead. Alternatively, you can rebind “Toggle Blender Operators Mode” to Shift+Tab if you prefer that.

Standard Operations

Standard Operations#

Axis Constraints#

All operations allow constraining the axes on which the operators operate. Press X,Y or Z to only use that axis. Inversely, use Shift + X,Shift + Y or Shift + Z to constrain to all axes BUT the respective one.

During any operation the mouse will be constrained to the viewport and will wrap around the edges if you hit the edges.

All operations also support Type to Transform.

Global vs Local space#

To switch between global and local space press the constraint shortcut again. For example, when you constrained to rotating around the Z axis and you are currently in global space, press Z again to instead rotate around the selection’s local Z axis.

Type to Transform

Type to Transform#

During any operation you can start typing in numbers and math operators to exactly define the operation parameter.

Formulas#

Unlike blender, the input supports math formulas. For example, entering 40+3*20-10 while translating will result in a translation by 90 units.

Units#

Unit conversion only applies for grab/translation!

In the Editor Preferences > Blender Operators Editor Settings > Translate you can define which unit is used to interpret the typed input. The default is centimeters which usually corresponds to the WorldToUnit scale in most unreal projects. If you prefer to use meters like in blender you can change the setting to any of these:

Control Rig

Control Rig#

In Control-Rig mode everything is the same except that the mode is a sub-mode of the animation mode. You can toggle it on and off via the toolbar button.

Splines

Splines#

Transforming spline control points is fully supported. Duplicating existing points requires some getting used to, however.

Duplicate Point#

Prefer to use RMB and select “Duplicate Spline Point” in the dropdown menu to duplicate spline points for now.

The other less nice way is to first select it and then press G to translate it, then while moving the point press alt to duplicate it in its current positon. The downside is that it is very hard to duplicate it in place because you have to move it first.
