CameraMapGemini is a new camera map modifier that makes your 3ds max projection work more flexible, more stable and easier to manage.

It overcomes the limitations of all currently available camera projection modifiers and finally allows you to use projections that do not rely any longer on having the same resolution and/or image aspect ratio as the rendered output image.

Features
* supports up to 10 individual projections ( = camera & map channel ) within 1 modifier, good for complex projection setups
* projection resolution settings are independent from render resolution, more flexibility for aspect ratios that differ from rendered output
* all projections can be toggled on and off individually within the modifier
* projection camera names clearly visible in separate scrolling text field
* projection cameras directly selectable in the modifier panel
* acts like a WorldSpace Camera Map modifier, takes object and camera transformation into account (this means if an object is moving through the projection it will update every frame), projections will always stay “live” and recalculate on the fly if the camera or the projected object is animated
* is in fact a regular ObjectSpace modifier, so other modifiers still can go on top
* more stable than 3ds max’s default Camera Map object space and world space modifiers, no more lost connections to cameras or mapping channel numbers when cloning, no reassignment necessary
* works properly as instanced modifier, many objects can share the same projection setup
* all parameters exposed and controllable via MAXScript
