Hasta La Motion!

Hi Vfxtalkers, I am nowdays getting flooded with lots of roto work and i have a little question,will a pen tablet will speed up the roto process and should i buy one of those ? If yes then what model and manufacturer ? I have a budget of $200.Your urgent reply will be a life saver.Thanks 😀

So we are working on several night time shots so I needed some specialized tools to deal with dark frames.

first up is:

We had to work with dark backgrounds with lots of lights…so i needed to be able to brighten and harden the lights in a defocus. So this is matrix based. Due to the current matrix limitations this is as big as i had the patience to make…lol, I was told this issue is fixed in Nuke 6, at that time I might go back and make a larger range.

Here are some examples.

And a new light wrap node…since I can’t stand nukes stock lightwrap. It works pretty much the same as the standard wrap, but it just deals with colors a little better and isn’t so uniform that you get wrap around dark areas. Enabling glow doesn’t just mirror the lightwrap effect on the outside it actually glows the hot areas based on the edge, so it can bleed hot areas into outlying bg colors. So far I’ve only used this on a dark scene with bright lights in the bg…works well. Give it a shot and see what you think 🙂

Does anyone know how you could convert a grayscale hightmap image into a normals pass using nuke? I want to then use the normals on a relighting tool. This would basically allow me to have a really nice emboss in nuke that gives much more control than the built in emboss.

Basically you would have to compute vectors based on gradients in the image. At first I thought maybe a matrix filter could be used to create a hacked normal map.. but I just don’t know enough about it to make it happen.

Any nuke wizards out there? 🙂
