Author Topic: AC3D ver 5 (021) c file format changed? (Read 614 times)

Hi

Here againg I'm spending my AC3D trial time and trying to figure out wtf is wrong with these darn simple objects

There is something odd with new AC3D ver 5021 file format OR some default settings must change to gain new OB compatible ac-files. OB crash everytime with new shapes when "Convert AC3D file" function but old ones goes just like that.

When I'm checking files with Notepad, I find that the "loc" infoline is in now several time in hierarchy tree? My old shapes have it just ones.

Oh S! if this is some classic RTFM thing...

Hello,

Looks like it was RTFM stuff so far.

I forget “zeroing” those additional polygons, which I was using for hierarchy tree building. I just need to set zero Loc position every time before grouping operation. The Hierarchy tree and object properties look correct. Ok, lets convert it in OE… The OE Crashing every time.

After few careful rebuilds I check the ac file with Notepad and find out the Loc info line missing totally. So far all exported original AH2 ac files contain Loc info.

If I modify my ac file with Notepad and add missing “loc 0.000000 0.000000 0.000000” info line, it converts nicely in OE. I Need to say, these new shapes still don’t appear in TE… Oh my.

Un-modified shape and modifiedshape

I use original AH2 FENCE texture for these both shapes.

Any help?

IIRC, there is somekind of definition in the files on how many text lines each object or group includes. So if you just add a line in a text editor, it may screw up everything that comes after that added line.... I experimented with this several weeks ago, so I do not remember for sure. Text editor is a nice tool for checking the locs though, especially since they cannot be edited from sub groups (since sub groups cannot be selected separately) in the ac3d hierarchy tool.

Hi Blauk,

I find more info about AC3D file format from here
http://www.ac3d.org/ac3d/man/ac3dfileformat.html

Check "Data" definition

I need to fix both Data infos to match them to object properties character lenght. The second Data info seems to count in also "loc" as a three character.

I luv this AC3D>OE>TE>Crash Mambo number 5 so much

Actually I'm beginning to wonder if this is a TE problem.

I've got a nice pine tree that just won't show up in the TE no matter what I do. I've tried an individual tree, and a tile with a forest of them with no luck at all. The object shows as present and is editable in the TE, but if you change pitch or zoom in there's nothing there.

I've even double checked the BMPs used to be sure they are 256 color 8 bit. So, I'm at a loss here myself. But that doesn't say much since this is my first serious venture into AC3D and the OE.

Hi

I made some tests and this appear in TE:

"AC3Db

So, is that loc info really needed anyway?

I would need some help from AC3D license owner.

Below is simple 2D fence object made with AC3D Ver. 5.0.21:

"AC3Db

Please, could you build a object Property Tree for it and post it here?

TY
