Track editing progress notes

[samsepi0l]

I always do this in 3doEd an then enter values in to ope.txt or track 3d.

Exactly - that's what I do too, but for some reason when I enter rotations in X, Y and Z it treats rotation in X as it is Z.

I found some original Papy trucks in original cleveland that I wanted to use in riverside. 

I converted cleveland so I could see them in OPE.  But these are actually drawn on their side, so I have to rotate by 90 degrees to get them upright.

Then I turn them about Z to get them pointed in the direction I want, but I want to slope them downhill slightly.  When I enter values in X, it just rotates in Z.

This 3do is called "sprttrk1".

   
   
   

It looks OK in OPE because the trucks have drawing priority over the hill. I just thin it would look better if I could get the nose to angle down a little.

DYNAMIC function has such structure:
name: DYNAMIC X, Y, Z, Z-axis, Y-axis, X-axis, scale, EXTERN "object";

Z-axis rotation goes first, then Y and then X. 3doEd program shows axis in normal order: X, Y, Z.

Yes - I remembered this. But still when I modify the angle so that it turns it in X, for some reason I get rotation in Z. Same result with modifications in 3doed or running 3d23do after modifying text file.

Very strange. I will not lose sleep on this for now since it looks OK in OPE even know the trucks are somewhat buried in 3doedit.

I tried all 3 directions and still no way to make the nose "dive" some.

Maybe because when you add 90 deg to Y axis and whole object rotates then Z axis is not vertical anymore? It's now horizontal like X, but X turns to vertical like Z.

EDIT
I think instead of using 90 deg Y rotation to place car horizontally you should use X and Z 90 deg rotation.
