The **Pressure** setting is for the graphics tablet pen. ### Size Parameter ID: `MDATA_DOODLE_SIZE` · Range: [0.00..+∞] ### Pressure Parameter ID: `MDATA_DOODLE_SIPRESSURE` The **Size** option defines the diameter of the Doodle brush. The **Pressure** setting is for the graphics tablet pen. Note that the radius of the brush tip depends on the **Size X/Size Y**setting (Doodle object: **Options** tab): The internal bitmap will always be scaled to the Viewport size. ### Hardness Parameter ID: `MDATA_DOODLE_HARDNESS` · Range: [0..100%] ### Pressure Parameter ID: `MDATA_DOODLE_HAPRESSURE` The **Hardness** setting defines the hardness or softness of the brush edge. The smaller the value, the softer, more transparent the edge. The **Pressure** setting is for the graphics tablet pen. ### Spacing Parameter ID: `MDATA_DOODLE_SPACING` · Range: [0..100%] This value defines the intervals between color application during painting. Lower **Opacity** and **Hardness** values make the effects of this option more visible. ### Auto-Add Frames Parameter ID: `MDATA_DOODLE_AUTOFRAME` If active, a new Doodle Key will be created (if none already exists) at each new frame in the animation where doodling takes place.
