Accessing one object in a whole my3d scene ?

[eviral]

Can i access to an object in a .my3d scene ?

I have a my3d scene (a temple) and i would like for exemple to change the texture of one wall (i have a lot of walls in that scene but i want to change properties of only ONE object in that scene).

Is it possible or a whole my3d scene is just one entity (one big object) ?

Thanks

No you can't.

One my3d file - one lightmapped mesh.

ZDimitor,

do you plan to release a new version of my3d file format with the support of bump, detail, normal, or parralax mapping ???

It would be soooooooo nice

Only when i'll upgrade my system, to support any shaders features.

I've never used My3d, is it like a model format (like 3ds, ms3d, x, etc..)?

If so, yeah, you should be able to edit quite a few of its parameters at runtime.

To edit material information:

node->getMaterial(index).Whatever = WhateverYouWant;
node->getMaterial(10).Texture1 = driver->getTexture(t_path.c_str());
node->getMaterial(4).EmissiveColor = Color;
etc.. etc...

Note that in your example, if multiple walls use that material, then all of them will change. I recomend using a specific texture on the wall that you want changed, I noticed Irrlicht combines mesh buffers that share materials in ms3d so this may be the case with my3d as well.

What, i cannot change materials at runtime with my3d? Why not? Apart from that i can have several lightmaps in one my3d. Would be nice to replace them at runtime faking light off/on.
Again, why not?
