Shade with vertex attributes creates out of range color values

Bug Reports
1

Steps causing the bug to occur

  1. shade lots of objects with vertex shader set to normals
  2. use a render scene to image
  3. render movie making sure there is a fade up or fade down of image
  4. during the fade up, out-of-range color values can be seen like static on edges of objects.

Have you found a workaround?

No

Other notes

  • Vuo version: 1.2.1
  • macOS version: OS X 10.9
  • How severely does this bug affect you? It’s annoying but I can work around it.

I hope that this is a problem with the way I am using Vuo. PS: resolution intentionally reduced to highlight issue. Bright dots can be seen on bottom image during the fade up. I would expect this to be a uniform fade up - not some areas with super bright areas? Also uploaded high resolution render with edge supersampling set to 8x-issue is still present. Arrows show issue.

Hey, do I need to provide any more detail about this?

Nope, sorry, just hadn’t replied yet.

We tested Shade with Vertex Attribute with 3 different graphics cards, reproduced the problem on one (AMD 7970) and not the others (ATI 5770 and NVIDIA 650M). It was actually fixed as a side effect of fixing Save Image node doesn’t clamp out-of-range color values.

Now, how can I get that update? ;-)
