Ok, the DH2 is a pusher plane. Yesterday I decided to get rid of the non textured engine and add a new textured one it. Well it turns out the prop on the FokkerDVIII is exactly the same as the DH2 one so I droped it in. I hid the REAL engine on the Dh2, deleted the prop and copy/pasted the new prop in. I added the DOF and everything. Now when I get in the game and turn on the engine the plane goes backwards! So I checked all the properties on the origonal DH2 and the new one with a new rotary engine thats textured. The propeller properties are exactly the same! So I looked in the Open plane readme on the SDOE disk and it said something about a engBackwards and propBackwards. I tried both of those and got the plane going foward but it doesnt control the same. The plane want to tilt to the left or right TOO much and the rotations with slow and fast prop dont match the real prop direction. So I ask you now how do I fix this!?!?!?! The origonal DH2 prop had no problem and it was a pusher and did not have the engBackwards or propBackwards settings. How do I get the plane goin foward with out using the propBackwards or engBackwards!!!IP: Logged |

If you search for shinden on the forum I have a japaneese pusher prop plane you can download an look at. TS ------------------

Tailslide. I'll look at this. One other problem Im having that I forgot to mention. When I turned the prop around and put in the propBackwards property so the plane could be a pusher; when starting the plane in air the prop spins..slows down and then starts spinning the opposite direction. But as Ive said I dont want to use the propBackwards property.IP: Logged |

I can't remember if the shinden had this problem it might. TS

Could this be due to the airfoil on the prop itself? Or is that what engbackwards and propbackwards does? Is flip the foils or does it just make the engine run backwards? I am curious too.

Ok, I think I have this problem somewhat solved. The propeller from the origonal Dh2 was JUST the propeller, NO rotary engine polys attached to it. BUT the propeller I got from the DVIII has the engine polys attached to it but it is all called a propeller. So, when Nuum put the propeller in the DH2 he did not have to worry where or how he put the propeller in because it does not have the engine polys attached to it. So in effect it is a normal propeller just pushed in back of the plane. My problem: Since I am using the DVIII propeller with the engine polys attached to it I have to worry because if I simply install the propeller in back of the plane the engine polys will be behind the propeller instead of infront of it. And since its already a foward facing propeller, when I flip it around to get the engine infront the propeller airfoils also flipped with it... thus causing me to go backwards. BUT, If I enable propBackwards I get some wierd torque on take off causing my plane to tilt AND if I start out in mid air, the propeller stops, and then starts agian going the opposite direction. So how do I fix these problems when using propBackwards or engBackwards?Second part: I have found a 'fudge' around to this. If I simply remove the Propeller Properties from the propeller with the engine polys and install a propeller with NO engine polys and make the now useless propeller with engine polys a child of the new propeller and line them up very precisely I can solve my torque and wierd prop spinning problems. BUT, I have NO fast or slow prop graphics for the rotating engine polys. Thus the engine poly turns really fast and doesnt switch. This is no problem because it looks kewl. But the useless porpeller attached to those engine polys also does the same thing. So it never switches to propfast or propslow. AND I also have dammage model issues to now worry about. BUT there is a solution if this can be done. Solution???: Can a object that is not a prop have propfast and propslow graphics on them? Can any object that rotates be told to switch to propfast or propslow after it reached a certain rpm? [This message has been edited by ArgonV (edited 06-19-2000).] IP: Logged |

You can just rotate the propeller around inside a 3d editor, that way you can have the prop face the opposite direction but the sim will still think its facing forwards. Then you can just use it like a normal prop (dont rotate it in OPS). TS

Yes, like TS said, the prop/engine object needs to be rotated in a 3D app. I will send you a rotated one if you want.Also make sure the weight and inertia boxes are the same as they were witrh Nuum's. The best thing to do would be to replace the existing prop LOD with the new rotated DVIII LOD. This lets you keep all properties the same while just changing the visual model  ------------------

Sv, as I have no 3d program I would love you to death if you rotated it in AC3D! Please send it me as soon as you can. Thanks! Oooo, one more thing. Dont forget to flip around the Fok8propFast, Fok8propBent and Fok8propSlow other wise when the engine gets going the engine polys on that will be on the wrong side of the propeller.P.S. In Nuums version, the prop weighed 307 lbs! and the engine only weighed 2! I changed the prop to 40 lbs and the engine to 300 lbs. The heavy prop ment that the engine start up was REALLY slow.

I think all the models you mentioned need to be created, right? When the enigne spins up you should see a blur where the motor is, what do you see now? Also the bent prop needs to show the engine mesh as well, right?-Sv IP: Logged |

Sv, the Fok8propFast, Slow and Bent you have in you FokkerDVIII plane. All that would have to be done there is taking them and flipping them around in AC3D so they will match the flipped FokkerDVIII prop I will use for the DH2. Now there is one small problem. The Fok8propBent does not show the engine mesh. So when the prop gets bent the propeller just shows and not the propeller and the engine mesh.Right now I have the 'fudged' engine (read what the 'fudged' version is on a above post) on the Dh2 so I can get the thing off the ground easily. The propFast, Slow and Bent Im using for that has no engine mesh and the useless FokkerDVIII prop mesh I have as a child attached to the actuall propeller has no propFast, Bent, and Slow at all. The effect that all this produces looks kewl, but it presents dammage model problems as I have said. IP: Logged |

So this is what we need:A prop with engine
A fastprop with fastengine
a Bent prop with engine. All orientated the correct direction, right? -Sv IP: Logged |

That is correct Sv. And dont forget a slowprop with engine. I think the slow and fast prop with engines are on your FokkerDVIII? But we definitly need a bent prop with engine. And yes all in the correct direction.IP: Logged |

Hey guys, I modeled an engine! I was gonna use it on my Bristol Scout, but it didn't work out, heres a pic!  ------------------

Aladar, why didnt it work out? And how do you get the textures to show up in OPS? All this time Ive had to do with grey as the only colorIP: Logged |

ArgonV,That is because Nuum never textured it. You should use Aladar's engine, but you may need to add a texture reference to your aircraft. I just add it to the ASC fiel generated by Hippie's extractor. Then rebuild the aircraft. Aladar, looks sweet! The prop looks real nice -Sv IP: Logged |

Sv, when you do the engine flipping, just use your FokkerDVIII engine. It is just about the same as Nuum's Dh2 engine. IP: Logged |

If you want the engine textured then I need to map it... My DVIII engine is mapped to one of the FVIII skins. I can remap the engine to a individual engine texture file, but you will need to add the reference to that texture in the ASC file. Do you just want to send me the DH2 minus the engine and I will add the engine? Or just add another texture to the ASC file for a 64x64 tif... call it engine.tif or something. If you do that then I can send you the engine mapped to use that tiff. -Sv

Sv, I'll try adding it to the ASC file. That saves upload and download time. I dont know exactly how that is done but I bet it will be easy.IP: Logged |

Sv, it appears you need a workable AC3d. At this point my AC3d is not regestered so I will have to send you the SM. I'll JUST send you the sm file because including all the rest like textures and stuff takes longer to upload and download. When you are done adding the new engine, send it back to me.IP: Logged |

Heya, I used the excelent texture from the SopPup. It didn't work out because I had to completely remodel the cylinders to co-ordinate with the texture, and after that it was too much of a hassle to place in the plane. Your welcome to use it if you'd like.------------------

Aladar, could you flip it around in AC3d so it becomes a pusher and then send it me. Id like to see it. Sv, I sent you the Dh2, I hope you got it.IP: Logged |

Seb...AladarThat's a real nice looking engine you have there! How long did it take you to put that together? The Dr.I could definitely use a new engine, but I don't have AC3D, MAX, or any modelling knowlege whatsoever.
And right now I'm working 60 hrs a week so I don't have time to be learning it. If anyone decides they can make the Dr.I better, go for it! When you zoom in close there is a strange texture where the prop is. I don't know how to get rid of this!
It needs a radial engine!
The texture-mapping needs to be redone! Hmm now I should be able to afford AC3D but I won't have the time to play around with that and OPS... ------------------
