I have the same problem. If I run the application using the OpenGL renderer, it works... but with the D3D renderer it closes itself automatically.
Here is the error in the Ogre.log file when running with D3D renderer:

What can it be? I need to use the D3D renderer...
Thanks in advance

Debug, debug, debug - the only way to know.

I'm using Code::Blocks with Visual C++ Toolkit... there's no a debugger...

I think the problem is in the mesh.

BTW: there is a way to test if the mesh is good formated or something like that.

What's the way to test the mesh?

A friend of mine have been trying the map in the scene with Direct3D renderer... It works on his system... How this is possible?

Some drivers are more tolerant than others. Some will choke on things that others let through, like zero-sized arrays.

sinbad: Thanks! Now I know that I will release my game with only one renderer (unfortunately I don't have much time for testing

)

But... So what do you think? The problem is in the mesh? I don't know how to resolve it...

i have the same problem... this giles exporter is unusefull

go superwalaber, we're calling u, fix that problem

If you don't have debugger well at least you can use NVidias PerformanceHUD (i don't know if it works on non nvidia cards)
you get a debug spew there and you have aadvanced renderstate view.

Also you can set DirectX9 to debug mode and turn up warning level and
check Ogres log files.

Well hope this helps.

I solved the problem... I was using the DirectX debug mode.. Now with the retail mode it works. However thanks!!!

I've downloaded Falagard's mod of walaber's exporter and found few small issues (well, maybe even small bugs):
1. scale is not handled properly. If I scale scene in max, then export it to 3ds and import this 3ds in gile[s], and then export into ogre, scene is not scaled, everything seems to be like in original max file, that is before aplying scaling. So I added PLUGIN_MODEL_GLOBAL_SCALE to LoadSingleModelData and store his scale in model's info. Then in LoadMeshData, just before CheckBoundingBox(...), I scale vertex by this value, so that model is properly sized.
2. so we get to the CheckBoundingBox. Well, it seems, that it should work ok, however it looks like variables mesh_max and mesh_min in model's info are _not_ initialized, resulting in enormous bounding radius. I changed this function a bit, and now it looks like this:

Code: Select all

void CheckBoundingBox( Ogre::Vector3& vec )
{
models[modelIndex].bound.merge( vec );
models[modelIndex].max_radius = (models[modelIndex].bound.getMaximum() - models[modelIndex].bound.getMinimum()).length()/2.0f;
}

and of course ExportOgreMeshes:

Code: Select all

exportMesh->_setBounds( models[modelIndex].bound );
exportMesh->_setBoundingSphereRadius( models[modelIndex].max_radius );

3. also, because we do like quaternions in our .scene format, then it may be better idea to handle PLUGIN_MODEL_GLOBAL_QUATERNION than PLUGIN_MODEL_GLOBAL_ROTATION.

Those are my little tips, maybe someone will find them usefull. Anyway, thanks guys for doing this exporter, I wouldn't even where to start

cheers

Because gile[s] is (even very low cost) commercial, I would like to ask what the status for the exporter is. Is it usable at the moment to use a prelighted scene in Ogre without big efforts or where is still work needed to be done?

Hangman · Post by **Hangman** » Thu Jan 05, 2006 2:05 pm

No it works well

SunSailor · Post by **SunSailor** » Sat Jan 07, 2006 8:12 pm

Sadly, I can't access the CVS for the addons at the moment, but is it true, that the exporter only supports exporting the geometry as one mesh? Isn't there a 64K border? We'll have some very complex scenes, isn't this a drawback there or is this really the better solution?

walaber · Post by **walaber** » Sun Jan 08, 2006 4:55 am

yes, that's true. my exporter will probably not handle very large scenes that way. in this thread (back toward the beginning), a modified version that exports to the .scene format was posted, you may want to look into that.

otherwise, you will need to make your Gile[s] scene up of several objects, and when the scene is complete, delete all but 1 object and export 1 at a time.

Hi, Walaber,
I've been using your exporter to produce lightmaps for environments made for the Blink 3D viewer. It used to work great. Now Blink 3D has been updated to use Dagon 1.2.0 (from Azathoth 1.0.6) and the material files produced by your exporter no longer make it through the material parser. Instead I get errors like these:

Code: Select all

23:31:10: Parsing script nakht.material
23:31:10: Error in material Gile[s]_MatTex_1_1lar 0 0 0 0 at line 3 of nakht.material: Expecting '{' but got scene_blend alpha_blend instead.

These errors are caused by extraneous characters in the material file (they appear to me as little squares at the ends of certain lines). Azathoth seems to have ignored these characters. Dagon doesn't and produces errors. As a result, the material fails and the environment appears with no textures. Can you look into this and see if you can correct the problem?
Thanks.

walaber · Post by **walaber** » Fri Jul 28, 2006 8:54 am

i believe I fixed it... and updated CVS... but I should check again. I'll repost once I have checked. the download on my website *should* be up to date though

ggunhouse · Post by **ggunhouse** » Fri Jul 28, 2006 6:44 pm

I downloaded the version currently on your website, but the exported material files still have the extra characters (line-feeds?) after every material name and texture name.

Hi!
How can I get exported mesh to receive shadows?

I replaced ground plane with my exported mesh in basic tutorial 2, but I can't get it to receive any kind of shadows. I have tried differend things I have found from this forum and wiki. I'm just learning to use Ogre, so there must be something I've missed.

I have also those squares in the material file, but after I removed them the mesh works (except shadows).

What's the lower button in the Gile[s] OGRE Exporter Options -dialog? I have only question marks in it.

I'm trying to find the gile{s} exporter, but Walaber no longer has it up on his site. Walaber oranyone else have it? Thanks!

It was put up on the Sourceforge ogreaddons repository also, AFAIK.

thx, I actually found it on one of my hard drives and posted the .rar archive to the wiki.
