‌Alpha Creation Controls

Low. Spinner. Sets the (smaller) RMS level that corresponds to an opaque pixel.

High. Spinner. Sets the (larger) RMS level that corresponds to a transparent

pixel.

Sharpness. Spinner. Gamma-like control that affects what happens to the alpha

for RMS levels between the low and high limits.

Shadow Maker. Button. Brings up the Shadow Map Maker script. From a light and mesh, it creates a texture map that is the shadow cast on the mesh by the light, from all shadow-casting meshes in the scene. The UV texture coordinates of the mesh are also set (to coordinates "as seen by" the light). To save the texture, turn Create Texture on (even though it is already created), then Set (filename), then Save, and finally turn Create Texture back off (so a texture extraction won't be run later).
