Problems Loading .x files in Irricht Engine that work in DX

[JamesCobras]

Hi i've had a quick look around and found only one post that's similar to this but with no real anwsers.

I have an .x file that i exported from Max 9 using Okino Polytrans. It works in the DX viewer perfectly. When i try to open it up in the Irrlicht Mesh Viewer it says it's loaded but nothing appears.

Here im trying to load output.x (It is in binary form)

The program '[656] 09.MeshViewer.exe: Native' has exited with code 0 (0x0).

I have some code that I will try to load it using just directx but i would love to use the Irrlicht engine. Ill edit this post when i have got it to work or not. As a beginner it would be great to have code with directions were to put it or even better a very small program showing it working.

Thanks in advance for all and any help.

James

The directx code i have is useless it didn't compile properly and loads of errors using the file that it came with.

Web address to the x file and materials.

I have an .x file

But we don't have it, and so can only guess at what the problem is. Any chance that you could make it available?

[JamesCobras]

The links to them are now at the bottom of my first post.

Index count per face not equal to face material index count in x file.

This is causing an early exit from the X file loader. It's returning an IAnimatedMesh, but it's incomplete (it has a 0 sized bounding box, for one thing). Skipping this check causes a crash, so it does seem to be a genuine issue.

Sorry, I'm not really into the joy of X, so I won't be looking into this any further. I hope there's an X files junkie who will be interested enough to give it a prod.

Thanks, thats one step along the way i hope there is an x file guru out there too.

I'm sorry, good luck fixing the problem

I think it's related to an error reported some weeks ago. There seems to be a way for a "compressed material list", which just stops putting the material list numbers if all numbers until the end will be the same. Weird, undocumented way, but hey, it's the .x format...
Maybe I can fix this.

[JamesCobras]

Maybe I can fix this.

Please, if you do i'll call you a God forever, i cannot find any game engines that load .x easily. If you can look into it it would be great and that goes for anyone else who wants to give me a hand.

[jontan6]

how about import the .X in a 3d software, and export it to another format?

[JamesCobras]

Export it to another format?

That is an option and a last resort. I'll need a good max 9 exprter. But Irrlicht should really be able to load the file if DX viewer can, don't you agree? If the Irrlicht engine cannot load this .x file it shouldn't say it can load .x files.

I don't mean to be mean or disrespectful to the programmers but i really think this needs a workaround or a fix.

[rogerborg]

Only if you define X files as "anything that MS's X file viewer loads". Standards be damned, eh?

Well it is their format so i actually do. But this is straying from the subject i just want it to load so any help would be great.

Thanks in advance for anyone who can help me.

[jontan6]

i suggest u consider workaround for the moment, so u can proceed with your project

I tried to convert the files with MView.exe, worked a little bit in that the error was gone and Irrlicht could render something. But the mesh still had some problems.
Is it possible to export the mesh in text form? It's soo much work to debug the binary files...

I'll upload them as soon as possible. Any thing else you want?
