Nice theory/thought but I doubt it simply due to the lack of situational awareness and feel that are missing from GPB.

I recommend you take a look at some tutorials for getting height data into 3D apps....

This should help: https://www.youtube.com/results?search_query=Getting+DEM+height+data+into+3D+applications

Sweeeeeet. Will look into these. Is there a lot of places mapped, as I did find a few sites but they seemed to be NA/Mainland European Mountains etc?

Most of the USA you can get hi-res(Lidar) height data from the USGS site for free.

Unfortunately the governments of Europe and UK prefer to protect the industries that have invested money to provide a paid service to obtain this kind of data, so we don't get the same freedom of information that the USA does with data like this, even though they have accurate lidar data sets that have been paid for by the public.
However, on some of the open data sites, individuals have posted good lidar and satellite data of certain areas of Europe and UK and other parts of the world that can be downloaded for free, so it's not all bad-news.  :)

You can also use Google Earth pro to download height data, but Google offset their data by 2 arc sec(to discourage piracy of their data), so their data is not particularly accurate for representing a real-life topographical 3D model.

And where would Piboso get the data from for this new tyre model you suggest?  :)
Probably there where Scawen Roberts got the data for his? :) More than 15 years ago, might I add...

Tyre model data is strictly protected by teams and tyre producers.... The chance of getting hands on real data for such a thing is practically zero.

The "Magic Formula" tyre algorithm is the most efficient and comprehensive model available; it's just all about the accuracy of the data to put into it that can be an issue.  :)
You are contradicting yourself there, Hawk. How come Pacejka's model doesn't need any "strictly protected" data, but brushes and other models do?
If you really suppose that the "Magic Formula" is that comprehensive and efficient, why even for cars you prefer rFactor 2? Though I might be wrong, but I'm pretty sure I saw you promoting rF2. I fully agree that it's a great sim. Mostly because of its tyre model.

I never said it was an easy feat to develop a new tyre model. It would take a lot of research. But judging by all the odd sideways sliding that still exists in GPB, I can't help but wonder if Pacejka's model really is suitable for bikes. I mean, it's not perfect even for cars.

In a way, a deformable tyre model should be easier to implement for a bike than for a car. Also it should be less taxing to compute real time.

I think your misunderstanding passerby..... The Pacejka's model is an algorithm that needs data to give a resultant action; that data needs to be accurate to give an accurate action, you see what I'm saying? :)
Basically if someone puts guess-work data into it then it's likely you'll get unrealistic action from the tyre physics; that doesn't mean that Pacejka's model is inaccurate or not suited for the task.
Any bike author has access to alter the tyre physics data to suit what they feel is best.... hence some tyre-physics are not as realistic as they should be because it's mainly guess work and not based on real data cause real data is almost if not even impossible to get hold of..... so we do our best based ideally on real-life racing experience, a lot of testing, and feel.  :)

You can even try altering the tyre physics data yourself and see if you can come up with a better reacting tyre model..... would be interesting to see what you can do.  :)

May I add that the tyre deformation would be even better coupled with a completely new tyre model? Are we going to use the "Magic Formula" to death?

Setups / Re: Schwaben_m2_18 Setup
« on: February 27, 2019, 01:33:42 PM »
I think you'll probably find that a setup won't help much at all..... The problem is very likely to be with the bike geom, tyre physics or maybe even the virtual rider settings and only Piboso can fix that.  ;)

After a quick test; Used (as usual but with the new fbx2edf) the export script and in this new version not works well, because the bikes textures importated have a flat black texture (with shaders ON). Without the script looks all good also with hdr enabled.

It is possible have a full bike example for 3ds max, so we can use the same "official" exportation way for any modded bike?

Personally speaking, it makes sense to only have the FBX format for exportation purposes in my opinion..... As well as saving Piboso time and effort in serving both exporters, the FBXconverter(when Piboso gets it working properly) would serve all good 3D apps rather than just 3dsmax users with the 3dsmax edf exporter alone.  :)

Jeezus, just realised this.

Why in hell did the mura (and the varese) get removed ?!?!?!?!?

I can only think Piboso felt he didn't have time to update them before he wanted GPB released?  ???

Bikes / Re: Beta15 updated bike list
« on: February 16, 2019, 12:00:20 AM »
As the mod bikes need to be updated it may get very confusing and hard to track which ones have been updated and will lead to many bike mismatches online, so maybe a thread could be started where there is a clear list of bikes updated by the modder who made it to keep things in order. New members would benefit from this too.

That's what the BikeMOD database is supposed to be for, ie: One place to get all the up to date mod-bikes to save any confusions, or am I missing something?  ;) ;D
