Tilt Brush, Tilt Brush, えもこ, チルトブラシ, 使い方,

This time, I introduce basic operations of a VR paint software, ‘Tilt Brush’ (for htc VIVE).
Please don’t be scared even if you are new for VR illustration or you gave up it because you found it ‘difficult’ before.
Let’s learn the basic operations of Tilt Brush by drawing a ‘flower’.☺️

Tilt Brush is very handy software to make VR space, as you can export your drawing to STYLY easily.
As this is just an introduction, I will explain how to use Tilt Brush with ‘Beginner Mode’ as default.
I don’t use any difficult tools! Let’s enjoy drawing (^o^)/

Set Environment

Firstly, change the backdrop (Environment) to suit to what you are going to draw.

背景ツール

The tool for Environment

Leave it ‘Standard’ if you didn’t decide what to draw.
Let’s adjust it after you finish drawing as you can change it anytime.
I recommend ‘Black’ to reduce eye strain.

背景を選択

Select ‘Environment’.

Select Brush

Next, select Brush.
Roughly speaking, you can classify the brushes into ‘oil painting brush’, ‘flat brush’, ‘brush for polygon’ and ‘brush with effect’.
Since there are too many brushes, taste a new brush little by little while drawing a picture.
Let’s be familiar with drawing in VR space by a straightforward “flat brush” as a starter.

ブラシの一覧

The list of brushes

Select colour

Next, select a colour.
It’s handy to save the frequently-used colours to the palette.
(Note that they will be cleared when you start as new).
As the colour sometimes look different under a certain condition of brush or light,  adjust it while drawing.
I have chosen yellow as I draw from the petals this time.

Let’s draw

Then, let’s start drawing a flower.
At first, adjust the width of your brush stroke by sliding your thumb from side to side along the brush-side(※1) trackpad.

線の太さを変更

Change the width of your brush stroke

You can draw a curve by pulling the brush-side trigger. Now draw with a dynamic stroke by using body motion.

線を引く

Draw a curve.

※1++++++++++++++++++++++++++++++++++++++++
Hereinafter, I call the controller used as brush ‘brush-side’ and the controller with Tool window ‘palette-side’.
They can be swapped by getting the bottoms of both contorollers touched.

Draw petals

Firstly, we draw the petals.

花びらの例

An example of petals.

In the case for ‘Whoops! I made a mistake’ situation, use ‘Undo’.
To take a shortcut, you can press the left side of the palette-side trackpad for ‘Undo’, and press the right side for ‘Redo’.

消しゴム、Undo、Redo

Eraser, Undo and Redo

You can also delete the curves you don’t need by ‘Eraser’.
With Eraser selected from the palette, touch a curve by the brush-side controller with the trigger pulled to delete it.

Draw a stalk

Draw a stalk next.

茎の例

An example of a stalk

Let’s try to use the ‘Straightedge‘ tool.
Select the set square icon to draw a straight line.

定規ツール

‘Straightedge’ tool

You can rotate the line with 45-degree step precisely by holding the brush-side trackpad while drawing it.
Use it when you want to draw a precise straight line vertically or horizontally, for example, when drawing a building.
Release your finger from the trackpad to deactivate it.

直線のスナップ

Rotate a line with precise 45-degree step

Press the set square icon again to exit from Straightedge tool.

Draw leaves

Next, draw the leaves.

葉っぱの例

An example of leaves

Let’s draw the leaves by ‘Mirror’ tool.
A cross line is displayed when you select Mirror tool.

ミラーツール

Mirror tool

Hold the box at the centre of the cross line by holding the grip of the controller and then move it to the centre line of the stalk.

ミラーツールを茎の中心に移動

Move Mirror tool to the centre line of the stalk

Now, when you draw a leaf on one side, the same leaf is drawn on the opposite side.
Remember it to save your time.

ミラーツールで左右対称に描く

Draw symmetrically by Mirror tool

A final touch

To finish it up, draw the veins of the leaves.

葉脈の例

An example of leaf veins

When you draw finer details like this, scale the picture and move it closer to make drawing easier.

【Scale】
Narrow or stretch your arms with the grips of both controllers held down.

絵を拡大縮小

Scale a drawing

【Move】
Move your arms together with the grips of both controllers held down.

絵を移動

Move a drawing

【Rotate】
With the grips of both controllers held down, move the right hand forward to rotate counterclockwise and move the left hand forward to rotate clockwise.

絵を回転

Rotate a drawing

By 3D nature of VR illustration, you often find your drawing misaligned with what you meant when viewing from another angle.
Check frequently from various angles by those operations.

Don’t forget to save your work whenever you completed your drawing or suspended your work.
You can find ‘Save Sketch’ below the palette.

保存ボタン

You can open the saved sketch from ‘Sketchbook’.
You can also open the sketches by other people from the same place so let’s learn by viewing various drawings.

Take a photo and share it

Let’s take a photo by Camera tool and share it with other people by SNS.
If you want to take a photo in a long shot, you can move far by Teleport.

A finder appears when you select ‘Cameras‘. Now, pull the brush-side trigger with the drawing kept in the finder.
