[help]Painting color/texture problem

before : many thanks for previous help... i did check the forum for related topic and i did find some.. some been helpfull.. other didn't but i still got a problem..

now : the problem that i'm having is that i can't paint color/texture to my terrain with the setOption("PaintCenter", &hit ); i dont really know why nor how and that what i would like to know to eventually make this work...

here's the code i do for the painting



std::vector<Ogre::Real> rgba;
rgba.reserve(4);
rgba.resize(4);

rgba[0] = 1.0f;
rgba[1] = 1.0f;
rgba[2] = 0.0f;
rgba[3] = 0.0f;
graphicSupport->GetOgreGameSceneMgr().setOption("setPaintChannelValues", &rgba);

brushArrayWidth = bsi*2;
brushArrayHeight = bsi*2;

delete mBrushArray;
mBrushArray = new float[brushArrayWidth * brushArrayHeight];

for(int i=0; i<(bsi*2)*(bsi*2);++i)
{
mBrushArray[i] = 1.0f;
}

graphicSupport->GetOgreGameSceneMgr().setOption( "BrushArrayHeight", &brushArrayHeight );
graphicSupport->GetOgreGameSceneMgr().setOption( "BrushArrayWidth", &brushArrayWidth );
graphicSupport->GetOgreGameSceneMgr().setOption( "BrushArray", mBrushArray );

graphicSupport->GetOgreGameSceneMgr().setOption("PaintCenter", &hit );


bsi = brush size...
before i go any further... this code work... how do I how? well simple enought.. when i change my cfg file to any of the TextureFormat from the demo it work.. i can paint color... ( did not tried texture ) but the not working part is when i take my cfg and change the TextureFormat to mine that is PLSM2Splatting ( oh and btw Splatting dont work but other do (other being base, instantbase, etc ) )
now for my cfg, material part

some SS to show how it's not working..
the working one but with not working painting...

the painting working but not the texture... with Base or instantbase set in the material file... ( hard to see but the painting is there, white on left side )

the painting working ( see the green painting ) but you see what's not working...


thanks in advance...
