T21s on NAM wide radius curves

[Magneto 316]

Hello everyone!

 

I'm currently developping a T21-based road signs street mod as I feel the urge to remove those ugly maxis signs out of the game

I decided to choose japan road signs, to me they are a good blend of US and Euro counterparts... If this project is ever released, I hope people out there will like it.

Anyway, I digress.. Progress is going good, but I need help for the smooth curves of NAM.

 

Here, the infamous 4x4 street curve    I just want to put a sign at the entrance like pictured here...

 

 

 

...and at the entrance of curve on the other side, of course.

 

 

 

As you can see, no problem of prop placement here.

But if I rotate the curve before placement, look what happens (red arrow): the prop is missing.

 

 

 

On the other side it's even worse: the prop is misplaced, and it's supposed to go in opposite direction:

 

 

Please note that I kept the same orientation for the 2 curves: they both follow the north-east axis. Only difference is the first hasn't been flipped before.

 

And here, the T21 entries corresponding to the "entrance" and "exit" of the curve:

 

 

 

Anyone has some insight on this issue?

 

Thanks !

In this case, you need two exemplars, one for the non-mirrored version and one for the mirrored version. Set FlipsAllowed to 0x02. Copy the exemplars and set the FlipsAllowed 0x01 and move and rotate the props around. See if that works.

Thanks for your reply Marteen. At first, I thought it was only dependant to RotationsAllowed but now that you speak of it.. if I had to guess, I'd say the piece has 2 possible rotations with its mirror counterpart, thus making  4 different orientations.

 

So yah I tried just with mirrored and non mirrored exemplars (and checked the used prop exemplars had their RKT1xm) as you suggested, the result was worse: absolutely no prop was correctly placed, and a lot were missing. much better! I forgot to generate new IID for the exemplars. No more misplacement, just one prop that will disappear occasionnally but only in a specific orientation*see edit 2.

 

To make it 100% work though  I suspect I have to fiddle with both Rotations and Flips properties

 

My idea:

 

1 exemplar with Rotation 0x01 Flip 0x01

1 exemplar with Rotation 0x01 Flip 0x02

1 exemplar with Rotation 0x03 Flip 0x01

1 exemplar with Rotation 0x03 Flip 0x02

 

And of course another 4 exemplars for the other tile, so 8 exemplars to cover 2 tiles in their 4 respective orientations. I could be very wrong in my assumptions though. I'm not even sure how mirroring occurs (horizontal or vertical flip?), so finding the good set up for Rotations won't be easy

 

Am I barely correct or...?

Edit 2: did some more tests with same setup, results are very inconsistent. There's some invisible trigger lying somewhere, can't put the finger on it

No, I suggest you should keep Rotations allowed to 0x0F

Pieces are often mirrored horizontally. However, in some cases, that screws up the orientation of the object in question, in this case a sign. You might want to fiddle around with the placement and the object rotation.

Thanks for your reply Marteen.

Now I understand how the flipping occurs, so I don't have misplaced props anymore or wrong props, such as left turn signal before right curve.

Good point.

Still, the results are very inconsistent: for a given position of the curve, sometimes the props won't show up at all , sometimes only on 1 tile...very rarely on both, I don't understand why.
