Hi
Try creating your fog in the App process and pass a pointer to that fog into the draw call back.
I don't think you can create a fog instance in the draw process, you probably go away with this on the O2 as you would be running single
process APPCULLDRAW while on the Onyx you will be running multi process APP_CULL_DRAW

Subject: multipipe fog
I have some trouble getting my fog to run.
On a single pipe linux machine, and on O2s it works like a charm. But on
our
three-pipe ONYX2 it doesn't work. The program runs, but the fog is
nowhere to be
found. I've put the fog in a draw callback, to ensure shared memory
access.
Any help would be acppreciated. My fog code can be found in the bottom
of this mail:
/Gorm
BTW. Thanks for the help with pfTexture::subLoadImage in a previous
post.
int pfFogPreDraw(pfTraverser *node,void *data)
{
static pfFog * fog = NULL;
if (fog==NULL)
{
fog = new pfFog;
fog->setFogType(PFFOG_VTX_LIN);
fog->setRange(1,8);
fog->setColor(0.0f,0.35f,0.5f);
}
pfEnable(PFEN_FOG);
fog->apply();
pfOverride(PFSTATE_FOG | PFSTATE_ENFOG,PF_ON);
return PFTRAV_CONT;
}
