LeftSkidLow 1 Posted December 22, 2007 I'm wondering (if I can figure out how in 02) if I change the attitude of the UH-60 to slightly tail low, how it will affect the ground contacts. I want to make the arma UH-60 a bit more realistic and easier to see out of. A real UH-60 hovers with the tail at least a few feet lower then the nose. In arma, the tail and nose are level in a hover, but the real problem comes when the flying the arma UH-60 in forward flight, because it hovers level, it flys at speed with the nose excessively low, which puts that stupid crossbeam in the window blocking the pilots view. Here a few examples of what i mean, look for the tail low attitude in a hover: Crappy video, and nothing happens until 5:10 so just let it load and jump to that time, you will definitely see the tail low. Fast forward to 1:15 to see the hover Share this post Link to post Share on other sites
LeftSkidLow 1 Posted January 4, 2008 I was able to get the mlod into o2 and put and rotate the model 7 degrees where I wanted it but it wont load in arma. I used someones UH-60 retex, and just replaced their uh_60mg.p3d with my edited mlod. Arma crashes and says "cannot open file blablabla/uh_60mg.p3d" Any help would be appreciated.

[aps]gnat 28 Posted January 5, 2008 You will be able to change the whole setup to hover as you want, but this will mean a 1) complete new UH60 2) Chopper that takes off movin forward early 3) Chopper that contacts ground tail first and "falls" forward on the front wheels. You might be able remove some of the visual effects by using dampers so it looks like almost 3 point touch down, but I think the amount you want to tilt is too much. There is another way except its a little complicated. I have discovered you can animate the WHOLE model/vehicle (havent found all the side effects yet, if any) If you "trim" or tilt the whole model at say "Altitude> 5" it will appear to hover as you want until just before it touches down. Using this method what it will look like cruising I'm not sure but you are likely the "un-animate" the trim with another overlaying animation linked to something like "speed > 10" Beware that this method *may* make the chopper much harder to fly.

First, thanks for replying Gnat, I thought I was all on my own. I'm not sure what you mean by #1, but if you mean I will have to change all the LODs, I already did that. #2 and #3, are actually part of what I'm trying to achieve (especially 3), as thats how they really fly. I'm not set on the amount of tilt yet, but the tail can hang as low as 8 ft below the nose in a hover in a real UH-60. Right now though, its like it doesn't even know its a helicopter, it wont takeoff or move or anything, none of the animations or textures work. I don't know what to do for it to fly again. Btw if anyone is interested here is a video of my latest sound modding from real UH-60 sounds. http://files.filefront.com/h60armasoundwmv/;9380909;/fileinfo.html Share this post Link to post Share on other sites
max power 21 Posted January 7, 2008 I don't have any advice to offer to help, but I'm following your project closely. That video is excellent. The interior noise of the uh60 is superb- just consider VON and other commos. Where did you get the rotor noise for the uh60, btw? Share this post Link to post Share on other sites
LeftSkidLow 1 Posted January 7, 2008 Thanks plaintiff, the rotor noise is from youtube actually, from a US Customs H-60 (this video to be exact )The engine volume on the inside was definitely too loud in the video, I've turned it down some already, but nothing is finalized yet. I just uploaded another video to filefront with all my heli sounds, most of them you have probably heard before in my other threads, just a few changes, the littlebirds and cobras have internal sounds now and a few other minor things. I'm going to post in addons asking for someone to write me a config and then release, I guess I'll release them standalone and if guys want to integrate them into fdf, modwar, chammy, etc. then thats up to them. I personally just use an FDF config. Share this post Link to post Share on other sites
Guest RKSL-Rock Posted January 7, 2008 Im not sure if this works in ArmA but in OFP you used to be able to adjust the neutral pitch using the Rotordive command: BIKI - Config_Reference...RotorDive <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE"> minMainRotorDive = -9; // CH47D maxMainRotorDive = 15; neutralMainRotorDive = -5; minBackRotorDive = -15; maxBackRotorDive = 9; neutralBackRotorDive = -5; Share this post Link to post Share on other sites

RN Malboeuf 12 Posted January 7, 2008 ok, i get it. there's animation source "rotorHDive". if i understand you corectly with this animation we can achieve that only rotor will pitch forward not the whole helicopter body ? Share this post Link to post Share on other sites
Planck 1 Posted January 7, 2008 Yes, the model.cfg entries are needed to make it work, but, if the entries in the config are not there then the AI will fly the chopper without changing the rotor angle at all. The rotors will remain at a steady horizontal attitude to the chopper body.The chopper makes large nose up and nose down movements to slow down and speed up. With those lines in the config you can actually see the whole rotor assembly change angle when the chopper speeds up or slows down and the chopper doesn't need to put its nose down or up at quite such a large angle I just tried it both with and without.

RN Malboeuf 12 Posted January 7, 2008 And if define maxMainRotorDive = 90; or smth ? Will helicopter body stay horizontal in flight ? then a solution for that MV-22 is found  Gnat, you only need to define those engines for rotorHDive animation )) Share this post Link to post Share on other sites

[aps]gnat 28 Posted January 7, 2008 then a solution for that MV-22 is found Gnat, you only need to define those engines for rotorHDive animation )) Well the solution i have works quite fine. I'd suggest this solution is less effective (for the v-22, not the uh-60) because i have LESS control over the hows and the whens of the tilt etc. Share this post Link to post Share on other sites
LeftSkidLow 1 Posted January 8, 2008 OK I tried changed the rotordive config values and it seems to only change the angle of the rotor as far as animation is concerned, it doesn't have any influence on where the thrust is vectored or how the attitude of the fuselage in a hover. I did finally get my edited model to fly somewhat, I guess I needed to add weight to the geometry LOD, as everything there said 0. Now I have to figure out how to make animations and textures work, these configs are so freaking confusing, I don't know how people do this. I copy and paste stuff but It always gives me errors and won't load Share this post Link to post Share on other sites

RN Malboeuf 12 Posted January 10, 2008 minMainRotorDive=-90; //'accelerate' dive forward. Higher (modulo) value means less pitch maxMainRotorDive=10; //'brake' dive. Higher (modulo) value means less pitch I guess it's quite the same about rolling with two other parameters. But as i said it only affects ai -there's no way to change rtorDive with player controls Share this post Link to post Share on other sites
