Virtual Mapper v2.3.1
Available for macOS and Windows.
About
This tool is basically a utility tool for non-planar video making such as 3D mapping and installation. It renders your composition on the video production software projected onto a surface of a mesh object and enables you to preview how the image will be projected in 3D space. You can transfer image from your software via Syphon or Spout (ex: After Effects, VDMX, Arena). Built on openFrameworks.

Instructions
1. Export FBX Scene
Virtual Mapper will interpret a scene file with following rules:
- All meshes whose names begin with
screen
will be interpreted as screens and the software will replace their surfaces with a texture specified in Source menu. - Screen meshes must have UV coordinates.
- All meshes whose names begin with
guide
will be interpreted as guide objects. - Other meshes will be interpreted as stage objects.
- Cameras will be imported and users can toggle them. (Orthographic camera is not supported currently.)
- The software supports only diffuse and luminance color of the material.
- The software does not support animation, light, spline, and embed texture in FBX format.
Example: Cinema4D
Setup scene such like this:
Then export FBX from File > Export > FBX (*.fbx).
