Simon, below are two screen shots of the bouncing aircraft problem. They both are from, "Royal Air Force - 1916_Confrontation - ACE07"


One is front left burning and bouncing wing over wing and the other is on the right of my aircraft that is just bouncing straight up and down...




Just off the rear tail is a plane I just shot down that is burning and flipping tail over nose...

I've experienced the same issue as described by dpteters95 several times.
It usually happens with very light and slow planes. I figure it is something related to the flight model used for that planes.
In fact it is rather annoying, because it makes rather difficult to shot down planes, and it looks rather ridiculous to see them bouncing over the landscape.
Sorry I cannot suggest a solution, I was only reporting that I've observed the same behaviour in two different computers.

Knowing some inner workings of other games (not IL2) I would imagine it is a series of issues that cause the effect.
  1.  Collision points in the 3d model let the sim detect interaction with the ground.
  2. When parts take damage and "break off' in some models the collision points are now missing and the model does not interact properly with the ground.
  3. the model is 'hitting' the 'ground' with a determined speed.  In real life the part would crumple and absorb the energy, in the game if there is no such energy ablating effect the sim physic's calculations make the part 'bounce' but does not reduce the speed and the part falls back with the same energy and bounces again.
  4. Airfields use a 'friction' effect to slow a landing plane (same reason you have to apply throttle to 'unstick' a plane on take off) without this effect in open terrain the part never will reduce speed until it collides with something the game is coded to apply a 'friction' effect or apply a 'crash' type effect.

  I have alpha tested other games where a bug in the code would allow broken parts to retain their 'lift' ratings and the game engine would still have the broken parts flitting around the sky long after the plane was on the ground.  Mostly flaps and ailerons but i remember one time when a whole wing kept doing a loop-de-loop while the rest of the plane spun in.

  Something needs to tell the sim to kill the speed of the plane when it crashes into the ground but the parameters would have to be precise enough to apply it in only that situation.  it is easy for a sentient human to know a crash from a landing but it is more complex in game code.

Am enjoying all aspects of CUP and have started on DOF.    Have flown several missions and they are spectacular!   Question for the group:  DOF in comparison to the other modules takes an inordinate amount of time to load (7-8 minutes)  eventually it does load and seems to play normally using the campaigns.   Other modules load in 2-3 minutes or less.   Is the amount of time DOF takes for me normal?  I have reinstalled it and meticulously followed the install instructions with no change in load times.   Any suggestions for me?  I will include any relevant portions of the logfile in future post.  It does show some graphic errors, but they don't seem related to DOF.  If I abort the load at some point, the last entry is always loading an aircraft flight model file, usually a Bregeut

tom petersen, I cannot find the post but somewhere on this forum the long load time for DOF was explained and I think it involved maps and airfield or object detail.

My DOF takes awhile to load too, way more time than required by the other modules.

[tom petersen]

After looking at the logfile text I can see that the flight models are being loaded multiple times for each aircraft.  I stopped counting at a dozen for the Dr1 alone.  Dont know what to do at this point except wait for the load time and play.

[EHood]

Forager is right, and I'm still getting used to the slow loading time. When my own installation reaches 60%, it seems to stall for at least 2 - 3 minutes. Once 70% appears, though, the remainder loads very rapidly.

It does take a while,  but it's certainly worth the wait.

FM & Hook problem, light weight and slow speed in the FM makes the plane less likely to explode and sometimes when it breaks up a (invisible) hook in a mesh causes the bouncing around behaviour, imho. Finding the culprit hook is very difficult. I noticed this with the Fokker E.III, Fokker D.II (made out of an E.III via hier.him editing) and the older frankenplanes. Unfortunately theres even a bigger problem to solve first: namely that many planes can take extreme amount of damage. Thats the one which annoys me the most.

Cheers

Do,nt seem to have any problems with loading times for DOF on this old rig.. Loading time in @90 seconds to 2 mins maximum.
 Only have CUP Forgoten Countries activated.

Thank You Monty!!!!!!!!!!

As Istvan has explained, Flight Model/Hooks issues affect some modded aircraft.  Everything in 410 based DBW1916, and its 412 spinoff Dawn of Flight, is built from scratch.  These collision behaviours are known (I have always considered them very minor issues) and improvements in those areas are on the table.

For me; the amount of stuff going on in these missions, the beautiful maps, aircraft and effects, makes it worthwhile.  The later campaigns, and the later aircraft, are also very much improved with regard to all flight and damage models.

Simon,
   I definitely agree the missions and maps are beautiful and are worthwhile but to say that this is a very minor issues would (to me) only apply if this was Flight Simulator X.  In a combat flight sim like IL2, where the main goal of most missions and campaigns is to kill the enemy, not getting credit for kills because they are bouncing across the landscape is a major issue.  Sorry, I'm not trying to ruffle anyone's feathers (I know a LOT of work went into each of these CUP modules) and I certainly don't mean to imply that the fix is easy (if it was, I would do it  ), but I think this should be a big concern.
