Seeing as the discussion is leading away from the main topic, perhaps it is best moved to PMs or split off to a new development thread :)
Agreed. Perhaps a moderator could delete the discussion between Gadg8eer and myself.

After quite a long break from working on this I've come back to continue what I started on a few months ago: revamping the existing bridges to work better with NRT and railtypes. Currently several bridges are too narrow and cause the NRT road surfaces to overlap the bridge heads which looks very ugly and distracting. The only way to solve this is to widen the bridge heads far enough that the guardrails will not get overlapped by the roadset. The bridge structure itself then also needs to be widened to match, resulting in me having to redo most of the graphics, alignments, and offsets all over again :lol:

Needless to say it isn't a 5-minute job so I've been procrastinating on fixing it. My first target was the steel truss bridge, which I already revamped the rail version of for the 0.4 release to turn into a rusty white cantilever bridge. I decided not to do any major changes to the road version since it is pretty much fine how it is, but the result looks much better now that it's wider, especially when using roadtypes. Here is a comparison of the old vs new:

While I had the bridge apart for maintenance I went ahead and freshened up the paintjob a little bit as well, adding a few more high and lowlights to make it just a bit more lively, and also fixed the lighting in the \ direction (shown above) which apparently was never flipped properly :mrgreen: All in all the result looks much better and I think I'm happy with it for now, so now it's on to the next one!

It looks great!
Thanks :)

Target #2 is perhaps the worst offender of this NRT-overlapping and the one I most looked forward to fixing: the stone bridge. This bridge is pretty much completely flattened out when using an NRT road set due to being so narrow and having tall railings. The reason it was so narrow originally was to preserve the sense that it is an old bridge, and old bridges tend to be fairly narrow compared to modern ones. There was always a slight issue with vehicles overlapping the bridge heads, but that seemed minor enough to live with. With NRT though, the issue is just too obvious and ugly, so needed to be fixed :)

In order to fix it completely, I had to forego the narrow aspect and sort of "flare out" the ends of the bridge heads to prevent them from being overlapped, but while still maintaining the same overall look. I did however decide to change this into an arch bridge like the rail version instead of the flimsy-looking pillar design it was before. In that respect it looks less like the bridge I originally intended it to emulate, but I think it looks much better regardless :)

This image shows an example of just how ugly the old bridge looks with RattRoads compared to the new, along with a small bridge in the bottom right of each to compare how it looks without an NRT roadset.

Two down, many more to go! :D

Hi all, it's been almost two weeks since my last update, but I've still been (slowly) working on this. I got a bit bored with widening the existing bridges so I decided to have a go at something a little more fun:

I've been sort of struggling to come up with ideas for more "futuristic" bridges to include for the later years, especially things which can be done nicely within OpenTTD's restrictions. There's just not a lot of unique designs that look good in an isometric view with a small repeating layout. So I decided to just work with what's already there, and give a new look to the tubular bridge.

The design was pretty tricky, and not just because of the awkward curves. I tried it first with "flat" glass but it looked a bit too boring, so I had to go and make it more complicated :lol: Each piece of the tube is actually two pieces which fit together with different levels of transparency, which is how the glass looks like it's sort of wavy or ribbed (still playing with the levels). It makes working with this bridge a lot more complicated than what I normally do, since each piece has to be layered and fit together perfectly in order to get the transparency effect right. I normally just draw everything as-is in Paint and only use GIMP for special things, so it's a bit different using it for the majority of the drawing process. :)

The bridge is still very much a work in progress (I only have this one view done so far) but I wanted to share it anyway. I'm still not sure what to do with the bridge heads, since the glass railings didn't quite work out like I was hoping. And I'm still considering trying to add some kind of "stripes" or something to the main tube to try to spice it up a little, but at this point I'm just happy to have the basic design in place and working in-game :)


Meanwhile, the other thing I've been spending time on in the past couple weeks was finally diving in to the specs and figuring out how to get parameters working. After a little bit of hair-pulling-out due to conflicting with the GRM, I managed to sort it out, so the next release will have a couple basic parameters for setting speeds and intro dates. I'm still not going to make settings for every bridge individually, but both options have "Sandbox" mode so you don't have to worry about speeds or introduction dates at all, something I personally will always have on ;)

The tubular bridge already looks great, and the bridgehead railings look good as well. There is a slight problem though: it looks like there are triangular gaps where the railing meets the tube edge. I think this can be fixed by raising the outermost part of the edge a few pixels so that its slope starts at the height of the railing, not at the surface height.

Awesome! I'm looking forward to this, not a single bridge set is compatible with NRT, let alone custom bridge heads. NRT compatibility could lead to custom bridge head compatibility with the right modifications.
