Great to see people enjoying this bike!

Doc, no current plans to do a supermoto version yet.. I will think about it :)

NorCal, thanks mate, but I don't give my models out for people to use. I would consider selling the mesh if people wanted to buy it for MXS use or something, but it's not ready for that game. I've never played sim but I know it needs way more work on the model to be usable. Time I just don't have :(

the bikes alot of fun to ride. one thing i did notice, the rear brake pedal, when you press the button the lever animates away from the bike instead of vertical up/down. and for whatever reason i cannot enter the garage in multiplayer with it or my game crashes

тғc

Good spot on the brake lever thanks mate, I'll try and get that fixed before Thursday so it goes into the OEM update fresh. There is a garage bug aparently, I've not had it myself. People say delete setups or something? Have a look on the forum for it, hopefully it will help..

exactly. Delete your setups and it's all good. For a decent time tbh.

So far with the Alta while playing online, if you delete your setup before entering online you get into the garage to adjust setups just fine. But after a few laps and then go back to garage to make adjustments, game crashes every time.

i think i derailed lol

I think the stock bikes have the same problem.

Quote from: hvpmvp on July 07, 2018, 10:16:00 pmThe rear wheel also spins out a lot more which I like. With the oems it feels like they never spin

The electric bike has all of it's torque at 0 RPM. I wonder if TFC made it that way?
Quote from: YodaIf no mistake have you made, yet losing you are ... a different game you should play.

On the power curves ("dynos"), keep in mind the Alta is a single speed, constant ratio rotating electric engine with a built in limiting system. (at 14k rpm in their case). Which means you'll have constant torque until the limiting system kicks in (and also a linear relation between speed and engine rotations). Some documents:

Theoretical Alta torque to speed ratio, as per their blog (ICE = Internal Combustion Engine):


Experimental Alta dyno, run by Philip (an owner who published it on their user forums HERE:

(it's plotted torque in ft-lbs per mph, because fuck the metric system).

I imported the experimental curves in MXB, extrapolating for the missing data points by taking the shape of the theoretical curve. Seems to work, since using the stock primary ratio with the 14 k rpm gave a max speed of 65mph, and behaviour in games tends to match the feedback given by testers...


I think the spin out more comes from having decent torque regardless of rpm. No need to pay attention to gear or clutch, twist, it's there (plus the Overclocked map is more a 350f than a 250f).

Hi all,

Here is my version of the Alta Redshift MXR. I've called it 2018 because it may as well be, but due to lack of reference pictures I think I've based it more on a 2017 model - There aren't really many differences visually. Ever since I first saw this bike I knew it would be a really unique and interesting bike to have in MXB, so I finally made it.

Please make sure you READ THE USER GUIDE BELOW before using the bike.



The model is edge split so no normal map, and it's actually remained a pretty decent size. The model really didn't take all that long.

This is I believe the first custom bike to include an animated rear shock and front brake cable. The rear shock looks great in replays but you don't notice it so much if in 3rd person, but the front brake cable brings a lot of immersion when riding in 1st person as it frees up when the suspension is compressed. I really wanted to add an LCD panel in the barpad computer with status light around the outside, but unfortunately that's not currently possible in MXB so perhaps in a future update.

The Alta's engine and geometry were compiled by Asdrael who did a fantastic job. This bike feels like I'd imagine it would in real life - It's got a ton of go, and when using the included 'overclocked' engine map it will be very competetive with other 250F's - Can't wait to ride this online in an MX2 lobby to see how it holds up!

I've included three paints - Redshift MX, Redshift MXR and what I've called Monster MXR - the graphics kit Josh Hill ran at the Red Bull Straight Rhythm just for fun, because there really aren't that many graphics options available for the Alta right now excluding custom jobs.

I'd like to first give a huge thanks to Asdrael for taking the time to make a proper engine for this bike, I can't say enough how much of an amazing job he's done, and how well it works considering the game doesn't support electric engines right now, and of course for giving the geometry the OEM treatment. The bike wouldn't have been in game without you mate simple as that  :D

I'd also like to thank PiBoSo - Firstly for letting me bend his ear on Steam about things I didn't understand (turned out to be a Blender FBX export issue ;D), for walking me through the animated part process, and for allowing me to use the stock transmission on and off load sound samples for the Alta's engine. These sound files are still encrypted as that's the way I used them, so nothing in the Alta is ripped or hacked.

I'd also like to thank Vortex_Damien, RC4187, HFR610P, Pacopastor, Geofanatec, Mace-X and anyone who I've forgotten who's helped me learn to model in Blender.

Hope you all enjoy - over to Asdrael:

MXB Alta user guide

  • Neutral ("N") is off. First gear ("1") is on.
  • There are no gears - stay in "first".
  • There is virtually no clutch. Turn off all clutch and shifting assists or it will bug out.
  • The bike should never stall.
  • The engine picks up only when at a complete stop or moving forward. If you go backwards, it won't run! (best done by light press of the front brake when going from a full stop).
  • All engine maps have the engine breaking equivalent of a 250f.
  • Depending on the map used, the "battery" should last between 45min and 2h.
  • The engine is capped at 65mph max speed with stock gearing (equivalent to 14000rpm from the engine).


Alta OEM process for anyone interested:

All geometry and values were taken from the Alta spec sheet and data given by Alta owners on their own forums (in particular, the dyno of all 4 maps of an MXR - thanks to Philip there!). The geometry was no particular issue, the engine is... electric. The only engine model currently in game is a combustion engine with gears and a clutch. This was heavily modified and tuned to accommodate an electric engine, which means there are some caveats.
  • There is actually a fuel tank of 0.2L with an ultra high fuel efficiency. So fuel weight shouldn't be an issue.
  • Normally, you can combine each power map with an engine breaking map (from no engine breaking to 450f equivalent). I just used a 250f model for all, this could be expanded on.
  • The clutch is still there (you can't remove it). It's just set as an on/off clutch. Don't use it ever, it makes no sense.
  • The hard cap of 14000rpm for the electric engine has been replaced by a silent limiter. Should function the same way.
  • Since there is no gearbox IRL, there is also no gear ratio. Since I had to use one in game, I put only 1 gear with a ratio of 1 (25/25 for thermal reasons).
  • The engine should never stall because stalling torque is 0 and every other standby value is at 1.
  • For the curious, the engine maps look like this: https://gyazo.com/4e84932b551c1b262234dea490d086ca (that's map 2 - Sport-,  0 to 15000rpm, 40hp max).


So to summarise the key points:

  • DON'T use Auto Clutch

  • If you roll backwards, BRAKE before you can throttle

  • Make sure you explore the ENGINE MAPS in the garage - Overclocked is best match for 250F

And remember, I get requests sometimes for this so I started including it - Feel free to Buy Me a Beer if you want to.

Enjoy all  ;D


is this something new? it's an old post but for some reason it's at the top of the "bikes" section so is it new or am i good if i have the newest oem pack?

тғc

It's at the top because someone commented on it today and I replied..

It will be included in the b10 OEM pack by Asdrael but it's not released yet. The old pack works but it's not configured for b10 changes.

TFC, i wanted to personally thank you for the Alta bikes. Im new to this Sim and am having the usual learning curve issues. Today I downloaded the OEM bikes pack and tried the Alta 250 and MAN.... its awesome. In fact, after 3 laps at Club MX, I improved my lap times. The bike just feels to handle better stock and the throttle response is amazing with linearity set to 80% and my xbox controller. I'll send you some beer money shortly.
Currently learning how to mod so that I can add value.
