Disable envMap effect while blending

Hi.
I've managed to draw dynamically generated texture over the "base" skin on DTS object, but can't make it apply "as needed".

It draws texture over the base, but I can't find out how to disable "envMapping effect" on it.
I'm doing it in TSMesh::setMaterial():

if (needSkinMod)
   {
      PROFILE_SCOPE(TSMeshSetMaterial___SkinMod);
      glActiveTextureARB(GL_TEXTURE0_ARB + TSShapeInstance::smRenderData.baseTE + 1 );
      glEnable(GL_TEXTURE_2D);
      glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_RGB, GL_ADD);
      glBindTexture(GL_TEXTURE_2D, th.getGLName());
      // set default texture unit...
      glActiveTextureARB(GL_TEXTURE0_ARB + TSShapeInstance::smRenderData.baseTE);
   }

This code I've placed right before " // emap texture...".

Here is the result of what I see in game:

I'm not fully understand rendering stuff there, sorry. What I do wrong? Any hints?
