Great Work! And A Request Please -> .hadd Format

 Hi all! Great work guys with the engine. Muchos gracias!

I'm would like to write .hadd file format exporter for a Lightwave but there's no specs of .hadd file format.
Could You provide it please It would be easier for me than trying to guess from example models You provide with the engine.

P.S. I've noticed that You are also have light data inside .hadd. Hmm ? Why? I've guessed it is model only file .... Guess I'm wrong.
Please help.

Thanks in advance!

 It would be great to see a .hadd format exporter for Lightwave!  (genial)

 Fantastic! We will give you all of our support.  (ole)

You really must create a .prehaddd file. This is the file exported from MAX. The engine when loads a .haddd look at the head, and if it's a prehaddd it transforms and save on it a .haddd

We have no docs about .haddd yet, as we think it's very easy. You can try it exporting a simple textured cube on MAX, and then take a look at the .prehaddd. Or you can export directly to a .haddd , the way you think is better.

If you have doubts, problems, please contact with me, i will send you the code ...

 Are you guys planning on making a Haddd editor that imports 3ds/.x files etc?

[Haddd]

 We have no plans on it. We are working hard, and the comunity starts to help us on creating new tutorials  :P , for the final 2.0 release with full source code.

We always believe that the comunity will help us writing this kind of exporters, thats why the .haddd format is so easy  <_<

This is a cube:

I thinks you should ask for:

 Do need a light defined in the haddd file? If so, why cant it just rely on scene lights?

When I add multiple tanks (HImport.Haddd.Load("tank"); ),  the materials get a little messed up, every time you add a new tank, the materials of all get a little brighter and uglier.

Do need a light defined in the haddd file? If so, why cant it just rely on scene lights?

No you don't. You can have only geometry, or light, or particles....

When I add multiple tanks (HImport.Haddd.Load("tank"); ), the materials get a little messed up, every time you add a new tank, the materials of all get a little brighter and uglier.

That's why the tanks has lights on it. So when you load it, you are loading more lights at the same position...

But if you want more tanks, you only need:

HMeshObject newTank;

newTank=tank.Clone("Newtank");

The problem about cloning the tank is that you must do it for all the objects that forms the tank...We need to save the hierarchy to avoid this problems.... :(

 I've played with Max a bit (Max8) to try to export a model in a research to do a Lightwave exporter.
Even for a basic scene I get .haddd without poly info in it. Something like this:

Anyway the model viewer that You have provided crashes on loading:
System.Exception: ERROR: file "", line 0: Couldn't load file:

 ... blah blah blah

This is a model with Multi-SubMaterial applied. On every submaterial there is a standard material with a bitmap as a diffuse map.

After that I've tried to simplify the test and created just a box(without mapping and textures). Exporting went well ... file looks like this:

But when I try to load it into a Viewer, it crashes and erases the whole .haddd file (0 bytes).
This is the exeption:
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

blah blah ..............

On a third attempt I've added UVMap modifer on the model, added texture to as a diffuse map in the material and applied that material on the test box. Exporting went well, and loading this model into the viewer didn't crash it, but the scene black. There was no model and also grid hasn't been drawn(I set it to draw grid in View menu). After that I've noticed that the viewer has changed the .haddd file (there was the polygon info).

Am I missing something here? Plaease help. (I've seen the export tutorial video and done as in it)

Thanks!

 You need the texture coordinates on the mesh. It's a must.

I don't know if you have seen the video exporter created by our webmaster. It's on the web... ;)

If you look at the file, there is not face information.....Strange, very strange...

Anyway, please send me the .max file, textures and the Prehaddd file if you find some more troubles.

 What if you want to load a mesh for collisions only?

[Haddd]

 Physics are not yet integrated on the loader. You must do all the job coding... :(

You can load, and hide a mesh, of course...

 It was my bad ... I didn't set units to meters, so exported box was either too large or too small to see.
Anyway, I was performing a new test trying to use few texture layers and I've failed.
I looked somethign like this(Max material setup), here we go:

- I had main material as Mult-Sub object material with 2 materials
- Each of these two materials is Standard material.
- Each standard material has Composite map on a diffuse channel with 2 Bitmaps

Reason of this test was to try to export multysub materials with layered bitmaps on each sub material.
Exporting failed in MaxScript exporter like this:
---- Unknown property: "coords" in Map #1: Composite.

I suppose that composite materials are not supported in exporting script?

Can You tell me how to export material with texture layers from Max?
And can You tell me how .hadd looks the having a material with layers.


Question #2:
- Does HADD supports skeletal animations, if so how it looks in .haddd file. Or it imports MD5 anim files for animated characters(models).

Thanks!  :rolleyes:
