[TEC] Pack3D and SH4...
 

Hi, I´m starting to learn how to modify/create ships and 3d objects for SH4.

OK, I´m making some tests on the Yamato, I exported the model from the .dat file using Pack3D, imported the .obj in 3DSMax and created a simple cilinder to attach to the bow of the original mesh (just for testing purposes). So, I applied the Yamato material to the cilinder and attached it to the original mesh. I´m not trying to modify the texture, it´s just a geometry test. Ok, then I exported the modified .obj and repacked it to the original .dat via Pack3d.

I created a mission with the Yamato in front of my sub and when starting it, at first, everything seems to be fine (the modified mesh is correct and the texture seems to be OK), but as soon as I approach the camera to the Yamato (F11) it just turns into this:

It happens when I approach the camera (arrownd 500m more or less) and then stays like this even if I take the camera back...

Also I noticed a difference between the default and the modified version before the texture turns into that alien thing:

As you can see the modified version is much more "clean" or "white". I think the problem here is that the modified version is not loading properly the Specular map (the "..._O01.dds)

Any thoughts on how to solve this?


Thanks a lot!

No fixes I'm afraid, but you've got more problems than the ones you mention...the flag is now 'hanging' upside down and look at your rear gun turrets!

I had the flag/turret problems when I tried to mod the Yamato.dat file and had no fix for it :(

Hi, yeah, you´re right, I didn´t notice those problems... the back turret is missed :o
mmm... maybe it´s flipped, like the flag.... that can be the cause....

The flag flip is a very common result in pack3d
but I havent seen it do that as such

Here is a closeup of the affected area:

Both back turrets and the flag are upside down. I have also found where that funky alien texture comes from, it´s "Caustics_new.dds" texture. It seems that when I get close to the ship the program tries to generate caustic and, instead of that, changes both color-caustics textures :o

Just for fun I shot some fishes to the ship and look what happened:

as soon as the torpedo hit the ship the texture turned into this :o:o:o I think it´s the normal map applied as color map...

Well it seems that Pack3D is no getting well with the new normal/specular/caustics maps...

Is someone else having troubles like these?

I have the same problems....

It is a disaster :down:
Hundred of tests and hundred of failures :down:

I think TMAP section is responsable of this.
I hope in future... Continuous to try...

As I understand it different versions of pack 3d are better for different
functions, aircraft ships etc. Not my forte yet but maybe a different
version might do better, you need some more expert advice than I can
give.

MM

There is the MAP of damages, I dont understand.
...and 10-1 and 6 chunks is different.

.....?

Section TMAP does not come imported from pack3d and the file become smaller.

Yeah, you may be right, I´ll give it a try and post results. Thanks:up:

I seem to remember that the DAT files edited by Pack3D become smaller than the original DAT files, so maybe there are some lines of data being missed out.

I tried most (if not all) of the Pack3D versions and couldn't find one which worked.

Incidentally, I managed to get the flag and turrets the right way up again by modifying their rotational axes, but then the turrets were swiveled as far towards the bow as they could move. Odd!

Version 2 is best so as not to " flip " objects

Yep, with pack3d v.2 objects do not appear flipped but the texture problem persist...I guess we have keep on trying :damn:

Pack3d
 

Hi,
Is not a problem of flip...
Pack 3d, any version, alters data in all file, and for the main .obj, it import only to the point TMAP. Change the total amount of byte.

In the first, file the .dat file after import .obj.
I the second file, the original...

I search a solution from much time...
I hope to find one solution... But is Hard! :damn:

Hey there,

pack3d doesn´t alter the data. It depends on your export settings of your 3d programme whether the data match to the smallest detail or not. The TMAP is not part of the *.obj file. And I don´t know whether pack3d would be able to import TMAP data if they were in the *.obj file.

I know how you feel man, this is driving me nuts too... But it´s possible: a few weeks ago U-5000 did a mod of the Yamato with the Imperial Emblem:

http://www.subsim.com/radioroom/show...ghlight=yamato

It´s perfect. I downloaded it to analyze what he did but actually I have no idea how he did it... :huh: If he is over here it could be great that he could give us some tips ;)

As for what I´ve doing I think there is a problem with Pack3d and SH4 it seems not to manage the normal/specular/caustics maps correctly when repacking (well, it´s normal since it was designed for SH3 where this maps weren´t used...) But then, I have no idea how U-5000 did it...:damn:

Pack3d
 

Hi DD,

I have try:
1) export 3d obj with Pack3d.
2) I have imported the same object, that I have exported, without to touch or save with software of 3d design. The original file exported, and it causes many changes and the result is that one in the previous image.

It import only to point TMAP. But it changes also other data...

...and I dont have a solution... :oops:

I have this file for Yamato, but have the same problem. This dat is more small compared with the original... And have the same problem. It CTD my SH4... :rock:

Hi UBOAT,
Pack3d doesn´t export this TMAP section. When trying to import your (original/altered) file back to the *.dat you have to do this by hex too. That´s how I did it with all the uboat interior files while working on open hatch.
Import to a dummy.dat file. Open the file and search for the object data, just the vertex coords. Triangle coords and texture coords don´t need to be touched. Copy these data and paste them before the TMAP section. Keep in mind that triangle and texture coords are located between vertex and TMAP. After all check/alter the size information for the data block.

I´m not at home. That´s why I can´t give more detailed info. Hope to be back at my desktop pc tomorrow noon.

Regards,
DD

Many thanks DD :sunny:
