Projection Brush

is a remarkably simple, yet extremely powerful tool which allows Blacksmith3D-Paint to be as powerful as any 2D painting application that you may possess. It allows you to take a snapshot of the current viewport, load it into a 2d paint application, paint whatever you wish, then bring the results back into Blacksmith3D-Paint.

Resolution

increasing this parameter beyond 100% allows you to export a higher resolution snapshot of the viewport, which reduces the possibility of resolution loss when transferring to and from the 2D paint application of your choice.

Take Snapshot

exports the contents of the current viewport to a file that can be quickly dropped into a 2D paint application for further editing. After clicking this button you will be prompted to save a PNG file. A corresponding .info file will be created along side of it containing the viewport information in case you change the viewport (e.g. Rotate, Zoom, etc.)

Left: Take Snapshot, Middle: Paint on separate layer in 2D application, Right: Save edited layer only and reload

You can utilize any number of techniques for making the edits. If you are simply painting features on top of the current textures, then we recommenced that you create another layer in the 2D paint application, paint on it, and then hide the base layer before re-saving the snapshot file. In that way, only the new details that you painted will be present, which will help guard against resolution loss.

If you plan on smudging, blurring or otherwise manipulating the textures that are already present, then you will want to edit the base layer, or save the file with all layers visible.

Reload Snapshot

imports the edited image file as a brush image, restores the viewport to it's original orientation (in case you rotated, zoomed or otherwise changed the view) and makes everything ready to go. We stopped one step short of actually applying the updated texture here since there will be many special cases in which you will want to selectively apply the paint. So, with that being said, simply paint the changes directly in the viewport, so you can be sure to avoid areas with a sharp drop-off that will cause the projected texture to “stretch” across the sides.

It's in the Details

After reloading the snapshot, you can paint the changes back onto the model as mentioned. However, you are also free to use another paint brush to apply the changes (e.g Shape Brush) or any brush that utilizes the Brush Image, since that's all it is The viewport snapshot was reloaded as a brush image.
