I think you want an ambiente light ???
Use setAmbientLight(...) (have a look at the API for more infos) !!!

i've tried the ambient light but i don't see any change

did you set your nodes to Lighting = true ???

of course, but i'm thinking that i'm having a problem with the mesh that i'm using, can i send it to yo and you try it?

Hmm, it could be that the normals are not correct, but I don't know if this also affects ambiente light...

Of course you can send me your mesh for testing !!!

BTW, what 3d editor you're using ???

how about trying to place your light stuff in irredit so you can have some realtime feedback?

Then all you gotta do, once things look as you want them to, is save as a .irr file and load it.

yes, i tried it, and i cant see the texture in irredit, could this be the problem? also i've upload the mesh that does don't see good if you cant sugest me some 3d editing software ( actually I'm using 3d Studio ) or can make me a litle tutorial of how to solve the problem. For my game I only need simple objects like smooth cubes or something like that.

EDIT: also i did put the gold material properties to the model in irrlith and it still sees bad

Now I did not test the models, yet...
I will test them tomorrow...

But I had a look with MilkShape3D ad they look fine with it...
I exported them to .x format !!!
Try them now, perhaps they're working now ???

i've tried it, now it works a much better, now i see the model as if it where gouraud shaded instead of flatshaded, but it loaded the mesh a litle moved to z position... can it be helped? or can I use 3ds and save somehow??.

THANKS!!!!!

Well, there are some DX exporters for 3dsm avilable...
But it seems they are not really easy to handle (many posts in the forum about this)...

About the position offset:
no the position is not shifted !!!
it's because I forgot one thing when I converted the meshes:
3dsm uses an other coordinate system, so the meshes are rotated at the origins !!!
Unfortunately this is hard to see if the meshes are symetric !!!

I just had a look at the coordinate systems...

You'll have to rotate the meshes about -90° on the X-axis !!!

Code: Select all

node->setRotation(vector3df(-90, 0, 0));
