Rotor Problem

Rey619 · 07-17-2005, 02:40 PM

Hi all,

I am tryin to create an AH-64D. It has 2 rotors. In HVA Builder, the animations are ok but in the game, the rotor at the back of the helicopter moves to two completely different locations. There two frames, the first frame of the rotor appears on the helicopter, then the second frame appears away from the helicopter.

If there's anyone who would know the solution, can anyone explain why the animations in hva builder dont appear in the game? And can anyone give me a solution to this problem?

First, delete your existing HVA file, because it's probably crap, in that it's trying to compensate for the voxel sections. To fix them, open each voxel section in turn in the voxel editor (don't try editing them in the HVA editor). Under Section>Voxel Header, edit the transformation matrix so it looks like -

1 - 0 - 0 - 0
0 - 1 - 0 - 0
0 - 0 - 1 - 0

I would guess the last numbers on each line are some non-zero value? If so make them so they are like above. Once you've done that, go back to the HVA editor and try again.

Thx ill try that. Just wondering, would there be a way to find the approximate or exact values of the far right column of the transformaion matrix or just go with trial and error?

I have no idea how those values are arrived at. I would just use (and have used) values of zero and rely on the HVA entirely to do the job.

I left the values as zero and the back rotor is still in the wrong position. So i guess i could try to change those values. I also believe the the siege chopper has values in its transformation matrix.

I believe i might of found the slolution to the problem... adding values in the transformation matrix in voxel editors doesnt do anything to the animation... if you have created an hva file, go into xcc utilities (newest) find hva file and copy it as a .csv file. This type of format file can be opened with microsoft excel. When you open file with excel, it has values... play around with the values... once ur done, go to xcc utilities and copy .csv file back to .hva (placed in same directory as the voxel file) and open .hva file with hva edtior. You will realize that the position of ur voxel wont be the same... I have no clue what values mean what but it is something to consider to maybe fix problems when it come to alignments in the animation.

Thank you so much for bringing this topic from the dead. Honestly, are these n00bs or necromancers?

You're the only noob in this topic, toadhead.

As for the original question, afaik the HVA Builder was seriously improved since you asked, it is possible that the new version will create correct HVAs.

improved? wasn't it completly re-written?

N00b? What did I do, DCoder?
