This is probably a noob question, but I can't seem to get it to work.
I'm trying to have an instance of a material; I.e., let's say i'm having 3 blocks of stone, all of the same material. I hit one of them, I want that block's material to change (somehow, doesn't matter). As I am using a MaterialPtr to set the blocks' materials nicely, they all point to the same material, so when i change one block object's material, all of them change.

Now I played a bit with material = new Material and other attempts, but I didn't manage to solve anything.

If possible, I'd like a solution on how to create a new instance of the material in the block's create method from the global MaterialPtr.

//Game class:
MaterialPtr mtrl=<some UID>;

//Block class:
void create(...){
super.create();
material = mtrl;
}

This is what I currently have. I want a way to create a new instance of that meterial.
material=new Material; material=mtrl; didn't make any difference.

Can someone tell me how this is done please? I know it's basic, but apparently I'm that bad.

The meshes/materials are pointers to a single object to save memory. Either you need to dynamically tell it which material to use each draw, or have a second mesh set up with the new texture that you can swap with.

I guess the first option is what I want; dynamically choosing the desired material; so how would I do that? How do I create a new separate material for each of my objects?

So I'm thinking about this < New(TYPE* &data) > function.... I have no idea how to use it though. Can't someone please help me? I'm damn frustrated here, I was hoping to send my friends some demos tonight for testing and now I'm stuck with this one last issue.

Bump your head into the wall long enough and it will eventuall break I guess. So after tons of blind tests I found the solution. Here it is in case someone else is having this problem:

void create(...){
super.create(obj);
Material *mat=new Material;
*mat= *mtrl;
material= mat;
}

so yey, I'm going to steam greenlight concept tomorrow

I think what you are looking for is MaterialLock

Well I got no answer, that's what I found and worked.

If I'm not mistaken, the MaterialLock will use less memory-something you can keep in mind for optimization.

Good luck with the Green Light!

Thanks. Well I have no idea how to use MaterialLock. It's comment isn't enough for me to understand what it it is, what it does, and most important, HOW to use it. Honestly I like the way Esenthel is built, with the tutorials and explained functions, but sometimes I really wish those comments were better or had an example too.

MaterialLock = material;
//Draw
...
MaterialLock = null;

If I'm not mistaken.

Rubeus is right

it's in render cycle
i use/draw for kimono other material and for body i use default material
[code]
void drawunit()
{
MaterialLock = Materials(UID(2390851165, 1317256765, 1535852195, 3501406879));
chr->mesh()->parts.first().draw(cskel);
MaterialLock = NULL;
chr->mesh()->parts.addr(1).draw(cskel);
}
[code]

Add to your object's class attribute of material id and use like this:
Now if you want to change material, you only need to change this attribute.
