These buttons can be used if you want to archive Stamps with individual settings for later use. Your Stamps (as well as all other Cinema 4D presets) will be saved to a library in your user directory under MAXON/Version/library/browser/user.lib4d.
In the Content Browser you will find the presets (to download, delete, etc.) in the Presets/user/Sculpt Stamps Preset directory.
Enables or disables the Stamp function.
Load the bitmap on which the Stamp function should be based here (white=min. effect; black=max. effect). In the Content Browser under Presets/Sculpting/Stamps you will find numerous stamps you can use (simply drag your selection into the Image field).
You can use either bitmaps with gray scales OR bitmaps with alpha channels - mixing the two is not possible.
Here you can define the rotation for the bitmap used by the Stamp function.
At the right is an fx button that works similarly to the Effector function in BodyPaint 3D (note in particular the Random setting with which you can randomly vary the rotation per impression).
If this option is enabled, the Stamps of mirrored brush strokes will also be mirrored.
Mirrors the bitmap horizontally or vertically.
Whereas the Grab brush, for example, raises (bitmap region lighter than Gray Value) or lowers (bitmap region darker than Gray Value) the mesh, the Gray Value defines the null level at which nothing happens. This can be accurately controlled by enabling the Show Depth option. This will display regions that lie below the null level in red and those above in green. If Gray Value is set to 0, black regions will remain unaffected by the brush, brighter values will cause the corresponding regions to be raised.
Note also the Sculpting presets Use Top Left Pixel For Gray Value, which do not always set this value correctly.
Enable this option if you want the stamp to be oriented in the direction of the brush stroke. By default, the stamp image should be oriented vertically (but can also be adjusted usung the Rotation setting).
Enable this option if the Falloff tab’s settings should influence the stamp image. Normally, a falloff is already included in the stamp image, in which case this option must not be enabled.
If the stamp image contains an alpha channel (which is nothing more than a grayscale image), this option can be used to decide whether only the alpha channel will be used (option enabled) or if the image’s RGB values will be used (option disabled; the alpha channel will be ignored entirely). If the image does not contain an alpha channel, this option will be grayed out.
If enabled, raised regions will be displayed in green and lowered regions in red (in the preview window below). Black regions are those that are unaffected. Except for the stamp image, this can be influenced by the Gray Value setting.
If you use stamp templates, the abrupt transition between, pixels’ can be softened by enabling this option.
Because bitmaps are square and brushes are round it has to be determined how the square stamp image can be fitted into a circle. This option determines this in the following manner:
