Sorry i steel not looked at you scene in MAX, i just go through the source code of Loader and Irrlicht.

The lightmaps are loading ok, but if I chek the log screen I get this warning every now and then:

"could not load texture: ./data/lightmaps/xxxx.jpg"

as if I were exporting my lightmaps apart. I export my lightmaps embedded with RLE 24 bit compression. Does it still look for a "lightmaps" folder?

Hmmm! Its strange.

Post your log here

Try to do following:

Find in file CMY3DMeshFileLoader.cpp the line

Code: Select all

if ((sub == LightingMapStr || (Name[pos2-1]=='m' || Name[pos2-2]=='l' || Name[pos2-3]=='_'))
&& 
!GetLightMap)
{
...
}

And patch it with

Code: Select all


if ((sub == LightingMapStr || (Name[pos2-1]=='m' && Name[pos2-2]=='l' && Name[pos2-3]=='_'))
&& 
!GetLightMap)
{
...
}

I think the loader don't like your textures with some names (and he think that its a lightmaps)

After that everything should be ok.

here's a screenshot of the log:

I'm going to try the fix you suggest in the cpp file and return. Thanks again; I'm glad we're being able to track several things down

great! it worked!!!

what was the error then? The only missing texture warning I'm getting is this one:
"could not open file of texture: data/(null)"
"could not load texture: data/(null)"

but this one doesnt have to do with My3d, right?

thnx again.

let me know of any other patches

Try to do this:

Find this line in

Code: Select all

if (texFName!="null")

and replace it with

Code: Select all

if (Name.size()>0)

There is 3 such lines must be in file CMY3DMeshFileLoader.cpp

Well!!!
I dont want to update My3DTools with such small bug fixes, so i'll do folowing:
I create new donloads links on my site (to CMY3DMehsFileLoader), and everybody can download the freshest version of loader (with all bug fixes)

See http://my3dproject.nm.ru

I changed the 3 lines but the null texture error still shows up.

but anyway, even with the other error it's working very nice!

let me know if there's anything else to try.

ZDimitor. maybe you have clue. using your gile(s) exporter and loading it to IRR while running DirectX everything works fine. running the same MY3D using OPENGL, I experience the following strange problem. whenever the camera focuses a MY3D-gile(s)-lightmapped-object, all GUI elements (2D pics, fonts etc.) turn black. as soon as the camera gets out of the focus of these MY3D-objects all GUI elements turn back to normal. as I said, the problem arises only, when using OPENGL. it is not an issue for DIRECTX. any idea ?

2wolfsb:

Its a Irrlicht 0.8 bug (in OpenGL driver), read some posts above, how to fix it.

ok. I will. thank you.

well, ZDimitor, I tried what you suggested. it didn't really help, as far as my special problem is concerned; though your bug-patch might be very useful in a different context. I played with my problem for a while and solved it in a rather bizarre way - maybe you have an explanation. I have a total of 9 "my3d-lightmapped-objects" (gile(s) exported). the problem mentioned earlier does no longer occur, if (only) one of these objects is set to E_MATERIAL_TYPE -> "EMT_LIGHTMAP_ADD". in that particular case everything is fine, also when using OPENGL. as I said, I do not have an explanation for this behaviour, but I can live quite well with the idea of assigning one of 100 objects E_MATERIAL_TYPE -> EMT_LIGHTMAP_ADD, if that resolves my original problem that all GUI elements turned black when the active camera was focussing a lightmapped mesh/node ....

Very interesting! I dont have explanation of this right now....

I can't get dynamic lighting to work, do i need to do something special?

edit: figured it out,
also, transparency maps for trees look chromish, and aren't transparent, do i need to code the leafs etc in?
