Just started working on this projection mapping project. The following are reeolutions
> 3-Side screens - 1920 x1200 each. (16:10)Ratio(Screen size 5.5mtr x3.5mtr)
> 1-Floor screen: 1920 x 960(Screen size 5.5m x 2.7m)
> And the final files to be given as four separate files

Check out this video for ref what the client is looking at:

What i have done i made a comp of 5760x2160
made spearte comps of
Screen 1: Left
Screen 2: Centre
Screen 3: Right
Screen 4: Floor

The Client wants it as four separate files to project from 4 different projectors
I am Confused in how will match the edges and give the required resolution split files.

Do i have to use any other software, any plugin..

well why dont you copy the comps into each other so that you can see the meeting edges?

then you could always place your comps as 3d layers in the configuration of the room to get a good view of how it will look like in the end.

I think the simpler method is to make 2 comps - one for the 3 walls at 5760x1200, the other for the floor as a standalone. For Comp 1's output, use the Render Module crop feature to output to the 3 files - left, centre, right. The floor (standalone) is not linked/joined in imagery to Comp 1.

A more involved method may be to comp the lot as a 3D Cube (do a search - the Cow has tutorials on this) or for Dome projection but only output the relevant parts without distorting for a dome, maybe something like this methodology may be helpful reading -

good luck!
