Coloring textures?

[Reiko]

Hello

I think the answer to this is very simple but I am not sure what I am doing.

I have a mesh with a monochrome texture. How can I apply something similar to a "Color balance" sort of thing, which exists in graphic programs such as Adobe Photoshop and GIMP, to the texture to change the color?

Basically, all my characters have a black-and-white hair texture and I want to be able to let the player choose an RGB color for their hair color. So rather than having 10 different textures that are coloured differently to choose from, I want to use the one black-and-white texture for everyone but be able to apply any different color to it.

What is the best way to go about this?

I'm not sure if it matters, but I dont have any lights, I just got the EMF_LIGHTING set to false on the node for the hair.

Thanks in advance.

See the DiffuseColor method of SMaterial, just get the material and set the colour to something other than white.

Hey again (forgot the pass to my other acc >.>)

I tried your suggestion, but I must be doing something wrong, cause the texture still shows as monochrome like before. (nothing changed)

This is what I've got.

Code: Select all

mesh = smgr->getMesh("data\\malehair.x");
node = smgr->addAnimatedMeshSceneNode( mesh );
node->setMaterialTexture( 0, driver->getTexture("data\\malehair.jpg") );
node->setMaterialFlag(EMF_ANISOTROPIC_FILTER, true);
node->setMaterialFlag(EMF_BACK_FACE_CULLING, false);
node->getMaterial(0).DiffuseColor.set( 255, 255, 0, 255 );

Is there something else I've forgotten to do?

Maybe you have more than one material?

I know this is pretty old now, at the time I couldnt solve it but I was trying just now, now that I know my way around irrlicht a little better, and I figured out a way to do it.

I just did

Code: Select all

smgr->getMeshManipulator()->setVertexColors(nodeHair->getMesh(), SColor(255, 0, 0, 255))

or whatever color. Pretty simple. This way was better cause I didn't have any lights, I think the diffuse color and such will only work with lights or something.
