first small tests for a tram simulator

I've increased the framecount to 5000... .
(0-5000)

but it does not help... .

while I don't know a word of coding, I know quite about the art side of formats... the frame rate thing may force it looking as static...

Just in case you increased the frame count, as your words suggest, but not the framerate, which is often referred to speed, FPS, or whatever. Just in case there was confussion.

B3D Pipeline Exporter was not my preference for characters, while surely for levels is the total solution..dunno, imo for characters seem to work great in all cases Unwrap3d. I guess you don't have it, but just to eliminate possibilities, if you download the free max plugin here:

I can simply do a test conversion for you, if that helps in determining the problem, and pass you the b3d file. You can upload (the *.u3d file, with the plugin copied, when save as, will appear this new format) to filesend.net or anyother. A character you don't mind if ppl see/open, of course, or pass me a zip password by PM. As u prefer.

However, imo is a coding issue, some setting like the one hybrid just told you. I just mean you may wish to have this additional test. I am somewhat interested to see if is a prob with b3d format when exported from max, which I doubt.

so, does it mean that there will be some way to grab spline interpolation how it was made from the package (curves in max, ipos in blender) and use that instead fo that trick? Or maybe is other type of trick...

i don't even know if b3d support carrying spline interpolation(for every joint) from the 3d package... Would be great for natural walks, and lighter files in hard disk/download....maybe more cpu, I dunno.Or maybe not, as processing for whatever every frame...I dunno.

Hi,

many many thanks for all the input I've got so far... .

I've uploaded an animated object

here

This is the most complex animation, I've done for my tram... . If this will work, anything will

(This one works flawlessly in Blitzbasic)

it displayed something strange in my unwrap3d...dunno is if I havent updated my b3d plugin to latets u3d version...

or maybe is just i sthat strange structure, looks like those things for the rain in cars...

animation has displayed...

maybe prob is you are doing a b3d with separate meshes and that messes a bit the irrlicht loader...

anyway, I exported as b3d from u3d, here you are

maybe prob is there's no material and testure...

many thanks,

YES IT WORKS... !!!!

I guess, I have to look for another exporter, or invest 50 $ into ultimate unwrap...

btw, this is a wiper and it should look like this (screenshot from Auran Trainz)

I tried to export a simple rotating cube with the pipeline exporter and even this dosesn't work... . So I had been wrong with some options, or it simply does not cooperate with the irrlicht importer... .

Blitzbasic is able to load the models without problems (but it's a bit overhelmed with smoothing groups I would guess)

many thanks again... .

You can always contact Luke and send him b3d files. He's an expert with b3d fles and will improve the loader once he knows about missing things.
BTW: Will this project be used in an academic setting or is it just for fun? I met a guy from Braunschweig several years ago in Copenhagen where he presented some train simulations (not 3d, but scheduling of trains).

Looks really nice, looking forward for a demo!

Hope you have no more problems with animated models. =)

Hi,

building the modells was a part of my exam work (building a training sim for tram drivers, based on a low cost railroad simulator (trainz 2004) 2 years ago. This was done in cooperation with driving school of a bigger german light rail company in Hannover. The overall result was great, but afterwards, the money was to short to really bring the system into service (and finish it beforehand, since the goal of the work was to show that it could be done, not to do it completely)... .

If someone is interested here is a Video of the project focused on road traffic... .

Unfortunately TRS is great in some things (really powerfull script framework, not to bad graphics) , but it's a bit limited in functionality and so I try to bring the stuff into a framework with a more open approach

. But today, it's just for fun... .

I will try to contact luke, perhaps importing can be improved a bit... .

I'm glad it worked, man

Just a clue...

this is formed, it seems, by several meshes...

also, is untextured, probably with no UVs...

my bet is the different pieces, though. But is a shot in the dark, Luke would know.
