terrain-volume-invalid

Since 0.7

A volume.shape or volume.cliff op cannot be built. The message gives the reason: a voxelM not in 0.25, 0.5, 1, 2 or not dividing the terrain's sampleM; a terrain with detail regions (a volume needs one sample spacing); mask or strength on a volume op; a keep part with no add before it; or a number out of its range.
