Depth map edge issues

Posted in: NUKE from The Foundry
I’ve been given a z-depth map for a 3D model along with its render.
The image is applied to a card and I’m using the DisplaceGeo node with a 3D camera and piped thru a scanline render. all of that works fine but the depth map has some anomalies around the edges that show as long spikes. There’s an alpha that should be clipping this but doesn’t. Eroding the alpha still doesn’t cause the spikes to be clipped. Any suggestions?

Other depth map questions:
1. The depthmap values range from 5 to 45 in this particular case, relating to real world measurements. The default DisplaceGeo is scale of .1 If I want to make sure depthmap creates true z in a world to match xy units are there specific settings to make sure that happens or will i have to manually scale until I think it’s right.

2. Should histogram work with these types of values? Doesn’t really seem to even when changing the input range.

Thanks.

city elevation

Posted in: Case Studies
Hi mates, I’ve got a doubt and may be one of you found a trick for it before.

I’ve got to model a volume elevation for a industry zone in barcelona, and I found most of the buildings done in google earth, but I can’t download them, just a few ones.

Does anybody know how to get them all at a time, or even one by one (a pitty option but… usefull)

Thanks everyone!

coloroverlay value set

Posted in: NUKE from The Foundry
Hi,

How is it possible to change colorOverlay of rotoshape using python. I tried the following. Although it works fine with tile color, gl_color and also as a matter of fact with the script too. However, it does not show the change in GUI. How do i get the change reflected in the GUI.

Nuke version : 6.6

Code:

col = nuke.getColor()
if not col == None:
    for n in nuke.selectedNodes():
        n.knob('tile_color').setValue( col)
        n.knob('gl_color').setValue( col)
        n.knob('colorOverlay').setValue( col)

Brgds,

kNish

Node issue

Posted in: NUKE from The Foundry
Hey folks,

I’m trying to build a gizmo based around the MarkerRemoval node – however i’ve found that it has a problem. If it’s given an alpha where there’s multiple points on the same horizontal line it appears to take it’s source for replacing anywhere on that line, rather than just adjacent to the individual alpha areas.

Kinda hard to explain, but I’ve included an example below.

Just wondering if anyone’s come across this before, or if anyone’s ever made their own marker removal style tool, with offset plates?

TIA

export nuke point cloud to ae

Posted in: NUKE from The Foundry
I ran a search but couldn’t find a thread on this, but does anyone know how to get a nuke point cloud track into ae?

I’m used to doing a track in synth eyes and then exporting to after effects via .ma and wanted to know if someone has written a gizmo for doing this from the nuke camera tracker and point cloud.

any help would be greatly appreciated – i need an emoticon here 😀 there we go

i know its silly….

Posted in: The Pad
Guys i am an artist with 3 years of exprience in vfx, i know that i can rip the shots from DVD for my showreel but i am not at all interested to do that, i have fallen for a shot in a French movie, so my query is can i use that single shot and work on it to show my skills and add a huge watermark of that movie name on that shot with credits. Is it legal doing this…I know asking this is a bit silly but before i go ahead i wanted few suggestions of experienced artists. Thanks in advance
