Deletes all or picked projection objects, which represent the placement of projective textures in the scene.
Delete Projective Texture Options
All – Deletes all projection objects in the scene.
Active – Deletes only those projection objects currently picked.
Every projection object is part of a texture map. (The projection object controls the texture’s placement.) When this box is checked, deleting a projection object also deletes the corresponding shader and texture map from the Multi-lister.
If the shader is in use (assigned to geometry), only the texture map is deleted, unless Delete Shaders with Connections is also checked.
When checked, the tool will delete shaders even if they are in use.
