Important
For drawing to work it's important to enable Support UV From Hit Results in the project settings under Engine -> Physics -> Optimization.
The drawing system has the three following classes:
- BP_DrawingBrush
- BP_DrawingBoard
- BP_DrawingEraser
These can be found in the content folder under: LIFVR Content -> Blueprints -> interactions -> Drawing.
You can use these classes by creating child classes of them or duplication.
BP_DrawingBrush uses the collision solver component to track the collisions on the drawing board to draw the lines. It also shows an example how to use the collision strength from the collision solver component for intensity and color changes.
Set you're custom brush mesh and set the DrawLocation component to the position where it's possible to draw with.
The DrawBrushLine method in the BP_DrawingBoard drives the actual logic to draw on the board. It requires the correct draw location. Additionally you can setup :
- Brush size
- Brush color
- Intensity
