1. Voxel Sprite Editor
2. Voxel Landscape Editor

Before painting use F11/F12 to resize up to 32 x 32 x 32.

• Arrow keys - move cursor up, down, left and right.
• Page Up/Page Down - move cursor forwards and backwards.
• Shift + (any of the above) - resize cursor.
• Ctrl + c, Ctrl + x and Ctrl + v - normal clipboard functions
• Space - paint voxel.
• Tab - delete voxel.
• 1-0 - change selected colour swatch.
• Delete - deletes the current frame.
• Home - copies the current frame to end.
• End - add blank frame at end.
• Insert - insert copy of current frame.
• Numpad 4/5/6 - previous frame / play and stop animation / next frame.
• F2 - Save
• F5 - Load

Set up some colour swatches (you can use the mouse for this). Painted voxels are not limited to swatch colours (ie. you can change a swatch colour and the sprite will be unaffected). HOWEVER: if you hold shift while changing a swatch colour, it will re-colour all voxels in the sprite that are the same colour.

THERE IS NO UNDO FUNCTION BECAUSE UNDO IS HARD. SAVE OFTEN.
