New version of the My3D tools for the Irrlicht released!!!

[ZDimitor]

Intro:
This tools allow you to exporting lightmapped scene from 3DMAX directly into Irrlicht.
Read more about this tool in this thread
http://irrlicht.sourceforge.net/phpBB2/ ... &start=150

New features in My3D v.3:
- lightmaps integration in my3d file - very, very easy to use exporter
(now you don't need to converting images into 'jpg' format and to copy them into 'Lightmaps' directory);

- two methods of compression of the embedded lightmap data
(simple compression and RLE compression);

- 16 bit and 24 bit format of the embedded lightmap data;
(for 16bit more effective to use simple compression, for 24and - RLE compression);

- lightmaps as standalone image files also possible
(but i don't use it any more in my project);

- GUI interface for the exporter;

- transparent materials support.

The My3D tools:
1) My3D Plugin (source and binary included);
http://zdimitor.nm.ru/MY3DPlugin.zip
1) My3D Example (loader for the Irrlicht and test scene included).
http://zdimitor.nm.ru/MY3DExample.zip

Usage:
1) Create lightmapped scene in 3DSMAX;
2) Use My3D plugin to export it into *.my3d file;
3) Load scene into Irrlicht with this class
(CMy3DMeshLoader included in My3D Example);
4) Enjoy!

SceenShoot (My3D Example with Irrlicht 0.7.1):


P.S.:
I test it only with 3DSMAX5, if you want to use it with MAX6, you must recompe my3d plugin with maxsdk6.

wooooooooohooooooooooooooooo!!!

great new version. downloading and trying immediately!!!


thnx Zdimitor!

[afecelis]

can't download the files. I'm getting the following message:

What that means??

Already found how to download the files!!!

thnx Dimitri!!!

whoa! helluva job with lightmaps included in the file!!!

works like a charm!

It just keeps getting better and better!

Great!
Have someone got this with max6?

Hi to all!

Last night i made some improvements to the CMY3DMeshLoade, in the createMesh function.
Here the source.
You can just copy/paste it into you project.
After this patch you'll have more pleasure to work with transparen materials.

[ZDimitor]

I have updated My3DExample with new patch!
http://zdimitor.nm.ru/MY3DExample.zip

@afecelis mirror it please.

Good luck friends!

[etcaptor]

I've compiled ZDimotor's plugin for max6.
Here is the link:

http://etcaptor.f2g.net/public/my3dmax6.zip

[afecelis]

done!

same DL link. thnx for the update!

http://www.danielpatton.com/afecelis/Zd ... xample.zip

@etcaptor: I'll try to compile a max6 version and upload it for testing purposes

[etcaptor]

By some reasons?? getSceneNodeFromRayBB function not work well with my3d.
Only works, if coordinates of node and camera are approximately zero.

[Bryan Abrams]

make sure to recompile one for max7

[Tyn]

Would it be possible to compile with GMax? Would mean people wouldn't have to 'aquire' Max 5 or 6 to use it.

[afecelis]

@Tyn: you need Max's render-to-texture feature to use lightmaps attached to Zdimitor's My3d format. Gmax (max4) lacks of it; it even lacks of an internal renderer (you have to render thru Yafray) so I don't think there's a chance for it.

@etcaptor: thnx for the max6 version. About source compiling; it compiled with no problem in My office computer, but at home I'm getting errors, so I'm beginning to think it's one of my system vbles. screwing up the compilation process.

cheers guys!
ps. I uploaded a very brief video showing the potential of the format here:
