Stephane,
If you look at Lawrence's email he describes a way to install draw
callbacks for the node you are interested in. By doing this you could
the texture being used.
In the preDraw callback:
pfTexture *desired_texture;
pfTexEnv *desired_tev;
pfPushState();
pfOverride(PFSTATE_TEXTURE | PFSTATE_ENTEXTURE | PFSTATE_TEXENV,
PF_OFF);
pfEnable(PFSTATE_ENTEXTURE, PF_ON);
desired_texture->apply();
// May have to use decal env this texture will get applied
// more then once.
desired_tev->apply();
pfOverride(PFSTATE_TEXTURE | PFSTATE_ENTEXTURE | PFSTATE_TEXENV, PF_ON);
In the postDraw callback:
pfPopState();
Give it a try.
