New Materials using "Image" Type Maps?

XeonXT · 01-17-2010 06:21 AM

Hello,

How can I create a new material on-the-fly using diffuse maps and such from Image types that have already been created? In other words, can I "directly" assign a diffuse map to a material object rather than load one from file? I see that the maps within the material object are pointers, and I cannot figure out how to simply assign an image object to the map.

Thanks in advance!

It is suggested to use Material::methods and import images from non GFX images
however you can use just pointer assigning:

Image image;
Material material;

...
material.diffuse=&image;
...

Thanks, sadly, I am still unable to figure this out..

Exporting and then loading doesn't seem to work (even when I save directly as GFX):

Code:

Image LandTex;

LandTex.create2D(128,128,IMAGE_A8R8G8B8,1);

LandTex.lock();

REPD(y,LandTex.y()){

    REPD(x,LandTex.x()){

        LandTex.color(x,y,Color(255,Random(255),Random(255),Random(255)));}}

LandTex.unlock();

LandTex.ExportJPG("LandTex.jpg");

Material Land;

Land.reset();

Land.importDetail("LandTex.jpg","LandTex.jpg","LandTex.jpg","");

Land.validate();

mesh.setMaterial(Land);

Pointing to the image creates a completely black landscape:

Code:

Image LandTex;

LandTex.create2D(128,128,IMAGE_A8R8G8B8,1);

LandTex.lock();

REPD(y,LandTex.y()){

    REPD(x,LandTex.x()){

        LandTex.color(x,y,Color(255,Random(255),Random(255),Random(255)));}}

LandTex.unlock();

Material Land;

Land.reset();

Land.diffuse = &LandTex;

Land.validate();

mesh.setMaterial(Land);

What am I missing?

Thanks for the help smile

Bah! How stupid, I forgot to make the Image global. That fixed the problem, using pointers now works flawlessly. That's all I needed.

Thanks for your help, and congratulations on a simply outstanding engine.

I look forward to purchasing a license in the near future grin

Are you declaring your material and image 'Land' 'LandTex' locally inside a function?

If yes, then they get deleted when the function returns, please define those variables globally.

how can i access materials settings by code?
if i have already saved material in an object and the object has been loaded trough WE.
things like glow or rgb lighting.?

if(Material *material=obj.material())material->

Yes, that is what was happening.
