Place Blocks
Choose the Cell type and placement mode in the editor. Plane mode targets a grid plane. Face placement targets an existing voxel face. Start with a floor and a SpawnPoint. Test the scale before building a large area.
Paint and erase
Painting changes the selected surface values. Erasing removes Cells. Check the current mode and brush size before applying a large change. Use selection and range tools when you need to work on an area rather than one Cell.
Materials and textures
Import a texture through the project texture controls. Imported textures belong to the project. Missing textures use a fallback when rendering.
Test changes
