I have a few gizmos where I sample color data from a user defined layer. I haven't used them as much in the last years but every time I do I'm having trouble to do the sampling (classic Nuke sampling black instead). If I recall correctly this used to work without any problem in previous versions (6-7). But I'm not completely sure about that.
I have been doing this by having the main stream just pass through the node, and then in a separate stream (no output) I shuffle the selected layer to rgb and then use a normal color knob to do the sampling. With this setup I'm able to have the viewer connected to the node (viewing rgb) and then by ctrl+alt sampling from the selected layer. See an example setup here <http://pastebin.com/q1KkceCn>. In the attached example it seems to work as expected. But I'm seeing lots of glitches when using this in other scenarios like sampling the Position output from a 3D scene setup. Sometimes it works though. Is there a better way to sample a custom layer? I still want to use normal rgb knobs to do the sampling. I tried having the sampling in the main stream and then copy back the rgb after the sample but with the same results. /Simon ------------------------------- Simon Björk Compositor/TD +46 (0)70-2859503 www.bjorkvisuals.com
