Importing Images - midspace/SEToolbox GitHub Wiki
Import an image allows you to create a photo realistic sheet of block armour.
Try to stick to small images, as large ones (> 400x200) take ages to load in Space Engineers.
Both Small and Large grids are supported.
Can be generated in either Light or Heavy armour.
If you have a .GIF or a .PNG with transparency, no block is created, allowing for complex floating images.
