how can I get several layers into  the picture viewer ?
like the multi pass  tools do.
i tried  something like  this
 
for (LONG n=0;n<20;n++)
{
bmp->AddChannel(false,false);
}
ok there seems to be a limit on a bitmap of  5 alphas which show up when i do ShowBitmap(bmp) ,  this is not really  what im after.
Multipass sends a specific channel with a name , which can also be toggled on/off , so id like to know how i can do the same kind of thing.
if this is not possible , is there any way to find out how the parts of muilt pass are put together (multi layer display) so i could maybe put the image together myself ?
also , if i start ther picture viewer from a video post plugin , cinema will freeze.ive tried all sorts of things to stop this , even built my own dialog and try to launch that , but it seems not possible to launch a dialog from a video post plugin. Is this correct?
 
thanks for any help.
 
cheers
 
Paul

You should check out how the videopost examples do it. Look for VPBUFFER_ALPHA and AllocateBuffer().

From the inner loop? No, that is forbidden since that part of the code is threaded and multi processor enabled.
