# Welcome to Blockbench 5.2 - The Screen-Space Update!

## Highlights of this update:
• Screen-Space Brush
• Layer Groups
• 3D Plane Reference Images
• Movable Reference Models
• New Color Wheel
• Better Inverse Kinematics

**Update Video:** [Blockbench 5.2 is out! All new features - Youtube](https://youtu.be/9MET5-wH5uw)

## Screen-Space Brush
The Screen Space brush (#1384) is a new brush preset that lets you paint on the viewport as if it was a flat painting.
It does not snap to the face your are painting, and is ideal for painting and blending together the edges between faces.

Like most brush options, there are two ways to enable this:
• You can use a brush preset. Press the small down arrow next to the brush tool and use the built-in "Screen Space Brush" preset. Or click "Brush Presets..." and create your own preset with the "Screen Space Brush Projection" option enabled
• Use the "Screen Space Brush Projection" toggle and add it to a toolbar or a keyboard shortcut. This is useful for toggling the option on the fly without switching to a different brush.

## References
• Added the new view mode "3D Plane" for reference images. This lets you place your reference image in the 3D space of your project, it will move with the model as you move your view.
• Added new "Add Reference Image" dialog. This provides basic options when adding a new reference image, such as selecting the view mode.
• Video reference images now have a video controls UI (#2800). This lets you skip to a certain part of the video, control the sound, etc. It has the following options:
* Play/pause button
* Video progress bar and timecode
* Audio toggle and volume control
* Full screen toggle
* Additional options (on desktop app and most browsers)
• Reference images now have better support in the 2D image editor, including support for Locked Blueprint mode
• Added new reference model "Minecraft Crafting Table"
• Preview Models can now be toggled individually from View > Preview Models
• Preview models can now be transformed from the same menu and will remember their position after a restart (JannisX11/hytale-blockbench-plugin#83)
• Skyboxes are now rendered in orthographic view (#3702, thanks @ewanhowell5195!)
• Disabled preview scenes in the GUI display slot (#3703, thanks @ewanhowell5195!)

## Inverse Kinematics (IK) upgrades
The IK System has been improved. Thanks @PROMETHIA-27 for their contributions!
• Added IK Poles. These are positions that can be placed via Locator or Null Object and determine in which direction an IK chain bends. This is useful for animating things like legs.
• IK compatibility with armatures (#3339)
• IK options and target elements can now be controlled in the Element panel
• Improved IK rendering performance

## Texturing Tools
• Added Layer Groups
• Added brush aspect ratio slider

• Fill faces and elements via Paint Bucket in UV editor (#3739, thanks @Kannoma!)
• Added setting to switch opacity sliders between 100 and 255 range (#3404, #2254, JannisX11/hytale-blockbench-plugin#182)

• Color picker now allows picking on locked elements
• Face selections are now kept while switching to Paint mode and painting

Welcome to Blockbench 5.0!
This update introduces multiple new elements, a new design, armatures, and much more!

Armatures
Armatures introduce a new way of animating models. Attach an armature to a mesh to create a rig, then animate the rig.
Rigs can bend and deform meshes, allowing greater flexibility when setting up a model for animation.
Alongside armatures, the new tool "Weight Brush" has been added. This tool lets you control which parts of a mesh are affected by a certain bone.
Select the tool, select a bone, and then paint on the mesh. A black area on your mesh indicates that the bone has no effect on it.
The warmer the color, the higher the effect of the bone will be. A red vertex will be fully controlled by the bone.
You can automatically calculate vertex weights based on the position of the bones, and the weight brush lets you refine this.
- Added Armatures
- Added Armature Bones
- Added new Weight Brush tool
- Added Vertex Weight and Vertex Bone Color view modes

Splines
Splines are a new mesh type that simplify the creation of long mesh shapes following a specific path.
Splines offer a great way to model objects like cables, branches, pipes, snakes, stylized hair, and all sorts of shapes like that.
