UVWs incorrectly streched after GBX Model Upgrade

I've upgraded at least 100 models for use in Halo 2 Vista by using the GBX Model Upgrader:
http://h2v.halomaps.org/index.cfm?pg=3&fid=2177


The app converts the GBX Models to the H2V .render_model format. Using it so much I know that it is crash-happy and must be used in the correct order to get optimal results.


Now occasionally I run Halo 3 models (I extracted and fixed) through it. Many of them come out fine, some require the apps built-in UVW fix. Other H3 weapon models such as the Missile Pod and the Battle Rifle come out with stretched UVWs such as the following pic:

I tried contacting the author of the GBX Model Upgrader (Jahrain) but never received any response.


So my question; does anyone have any idea how I could get around this issue, or what is causing it?

I know for a fact that the UVWs are retained if the model is part of the BSP or if it is used in HCE, the problem is happening during the upgrade process, I've tried rotating and flipping the texture to no avail...and that is when I noticed that the texture is being stretched incorrectly.

reset Xform

edit: 'no' to the question you're gong to ask, and google.

I definitely tried that and there was no change in the UVWs. I also repaired the few remaining errors but the texture continues to fail, and recall I stated it does appear correctly in H2 Sapien (as part of the BSP) and it looks fine in HCE, the issue is with the GBX Model Upgrader, which I do not expect anyone to have much experience with. :(


We've got a nice BSP of Valhalla and I was hoping to get all the weapons together, have most of them besides this damn Missile Pod. I would map/mod in HCE but I prefer the H2V engine, just not its lack of awesome tools.

I had a tool called Poly Cruncher which may have helped, unfortunately its already expired.

I ran into the same issue with the H3 AR, luckily I was able to get one of the models to work (either FP or TP) so I just duplicated the one that was working and changed it accordingly. If I could just put my finger on what the Upgrader doesn't like about certain models, be it errors, too many polys or what not. I've tired many permutations, not the type to give up easily.


Thanks anyways.

here's a nifty trick not many people know about, but often fixes 'weird' problems.

make a new box. just a regular box, nothing special about it.
convert to editable poly
hit attach
attach your existing object to the new box.

magic.

I have no idea if this is fixed or not, but incase it isn't:
At the .render_model file, at the top is "Compression information", add to the first 3 values -1 at the left, and 1 at the right. Then for the primairy texture co-ordinates add 0 to the left, and 2 to the right. This did fixed it for me once!
(I only really used the program once :p)

Upon further testing I have established that the problem is still with the Upgrader. Usually I import a .GBX_model or .OBJ into 3DS Max 8 and set it up for upgrading.

Halo 2 models usually come out right and if not can usually be UV Fixed in the upgrader.

Halo 1 models usually work as long as they originated from Halo 1's tagset.

Halo 1 models that are from other Halos (such as 3, ODST or Reach) are much trickier even though they look fine in Max and when put into Halo CE.



So I started upgrading the original (unmodified by myself) .GBX_models and still the error (bad UVWs) is there after upgrade. Thus the problem is not the model exactly, it is how the Upgrader handles them.

Game dead, have fun...

Can you maybe give me one of those models that don't work properly in the upgrader?
I'd like to have something to work on too!

Sure, here are a few retail H3 weapon models (hopefully you have 3DS Max 8).

The problematic models are the BR, Missile Pod and Spartan Laser. For the AR I had the problem with one model but was able to get the other to work (don't recall if it was the FP or TP) so I used that working model for both and changed the frames/markers as need be.

I've found it, look at the picture below:

After I've had good results, I tried to replicate what you had, and I found that too.
In the upgrader there is an option called "UV Fix", what it does is multiplying the texture co-ordinates by 2, meaning, you get the results like you had. (stretched)
Without this option, it works splendid!

Now, I don't know the correct way to change things within the .render_model file for weapons. But I do have the .render_model of the fixed splazer(fp) here:

If you want me to do your other models too, then please ask!
I hope, this time, I did helped :D
