Rotation Matrix Assistance for Class Light Hoods

[PullmanCar]

Hello,

I am able to attach child objects and rotate "solid" turns, such as 90 and 180 degrees, but how would one trial say a 45 degree rotation, and handle minimal horizontal rotation?

Many overlook the small hoods Illinois Central locomotives had (dating back to the steam era, my office has 2 from a passenger engine).

These hoods were included on the E units, and therefore pointed to the direction of the E unit nose. Might someone be able to provide some rotation assistance.

Let TS calculate that for you !

Make shure that random twist is not set in world editor :

Create a freeroam.
Place an asset on the ground (it does not matter which one, but you should better see a front or back)
and turn it while angle is locked:

Open your file manager. Goto the scenario with your scenery asset (just sort the scenario folders by date)
Inside the scenario you'll see a folder "Scenery\". Enter it.

Serz the bin-file and open the xml with your editor, here in Notepad+++ :

You can now use the entries in the box for your matrix. Just write it from left to the right, line by line one after the other :

Code: Select all

0.7071068
-0
0.7071068
0
0
1
0
0
-0.7071068
0
0.7071068
0


These are the first 12 values of a matrix. Below would be the position (the very last entry is always 1).

An example :

Code: Select all

<Matrix>
   <cHcRMatrix4x4>
      <Element>
         <e d:type="sFloat32">0.7071068</e>
         <e d:type="sFloat32">-0</e>
         <e d:type="sFloat32">0.7071068</e>
         <e d:type="sFloat32">0</e>
         <e d:type="sFloat32">0</e>
         <e d:type="sFloat32">1</e>
         <e d:type="sFloat32">0</e>
         <e d:type="sFloat32">0</e>
         <e d:type="sFloat32">-0.7071068</e>
         <e d:type="sFloat32">0</e>
         <e d:type="sFloat32">0.7071068</e>
         <e d:type="sFloat32">0</e>
         <e d:type="sFloat32">0.45</e>
         <e d:type="sFloat32">3.41</e>
         <e d:type="sFloat32">-5.345</e>
         <e d:type="sFloat32">1</e>
      </Element>
   </cHcRMatrix4x4>
</Matrix>

Thank you very much Kris. Thanks to your help I give you a proper IC E8 (4023 and 4033 survive, plus fictional 4044, and possibly a fictional 4045 in the future). The headlight and visor alignment are thanks to your help. Drangus (of the Illinois Central Route: Iroquois Prairielands expertise) did the visors.

Yet again the helpfulness of RWA and this forum knows no bounds. Thank you.
