3 screens side by side

Hi all,
We have a cube with 3 sides. Each side has 1280 x 720 pixels, totaling 3840 x 720 pixels.
We did:

  1. Turn left the camera’s character.
  2. Add two new cameras to the character, with front and right views.
  3. Via blueprint, added two new characters and associate the front camera to the first and the right camera to second.
  4. Download the source code to change the placement of the screens so that they are side by side.
    Surprisingly, with little work almost everything was working as expected. Missing hit the alignment of screens.
    We try different parameters for FPerPlayerSplitscreenData as:
    [FONT=Courier New][INDENT]0.33f, 1.0f, 0.00f, 0.0f
    0.34f, 1.0f, 0.33f, 0.0f
    0.33f, 1.0f, 0.67f, 0.0f

0.333f, 1.00f, 0.000f,0.000f
0.334f, 1.00f, 0.333f, 0.000f
0.333f, 1.00f, 0.667f, 0.000f

0.34f, 1.0f, 0.00f, 0.0f
0.32f, 1.0f, 0.34f, 0.0f
0.34f, 1.0f, 0.66f, 0.0f[/INDENT]

But the result was the central screen or a bit higher than expected, advancing on the side screens, or the central screen much smaller than expected.

Anyone have any suggestions?

(sorry my poor English)

Photos of the 1st test, where the width of the screens were set to 0:33, 0:34, 0:33.

Photos of the 2nd test, where the screens were 0:34, 0:32, 0:34. In this case, the total image width was smaller than the previous test, as can be observed in the second picture.
