Hi guys, I'm struggling a bit with the examples in the docs. I have a node
where I'm processing for RGB but in order to do so I need the depth of each
sample.
The pertinent parts of my code look like this:
virtual void in_channels(int, ChannelSet& channels)
{
if (channels & Mask_RGB)
{
channels += Mask_RGB;
channels += Chan_Z;
}
}
virtual void processSample(/* args... */) const
{
RGB attenuation, inscattering;
bool processed = false;
foreach(z, channels)
{
if ((z == Chan_Red || z == Chan_Green || z == Chan_Blue) &&
channels.contains(Chan_Z))
{
// do stuff...
}
else
{
output.push_back(deep_pixel.getUnorderedSample(sample_no, z));
}
}
}
My trouble is the channels I'm given never seem to contain the Z channel.
Trying to access it anyway causes an abort (obviously). How do I tell Nuke that
I absolutely need depth along with the r, g, b channels?
Cheers,
Anders
