This week I had 2 meetings with KK and Giulia and one meeting with Dom, I had issues with the completing of the lighting tasks, KK asked us to match the lighting, prepare the macbeth chart and try to set the AOVs and render layers. The AOVs did not work for me, not the disabling of the image plane and skydomes.
Lighting
We began by rendering the reference spheres, which I had issues with because I could not disable the image plane nor the skydomes from the render so the result was not the expect, but KK showed us a way to set up a “button” on a new shelf in maya where we could turn off and on the image plane.
The skydomes are deactivated by the render layers which is also something very confusing to me, but we figured it out and were able to rende the spheres to get to nuke, on giulias’ machine. I kept having issues so KK fixed them during the week and got back to me on this weeks’ second session.
This now has to be imported to nuke to get the light matching.
With the spheres in nuke we can create another viewer window and match the lighting with the footage through a bounding box made on the lighter area of the grey sphere and the same process for the chrome sphere.
After this, KK showed us a cool way to solve this hdri problem, by croping the chrome sphere from the footage and with a spherical transform node get the “HDRI” displayed in it.
Ofcourse, the result was not the best but we got the idea of how to see what really is on the chrome sphere. On the second meeting, KK fixed my scene and I was able to export the spheres correctly, and he taught us how to make a projection on the geometry using the node editor in maya.

After this KK showed us how to get the Macbeth Chart ready to import to the scene and have it as light reference. On nuke, we must rotate the image until we get it aligned, crop it and use the schew setting on y and x and distort the image until it is as much as possible like a square.
While treating the macbeth chart we noticed the footage had already been edited to look like a night shot so we got the values closer to the original before exporting the final chart image.
Matchmove:
On matchmove this week, I had a meeting where he told me the best way to get the points to track on a blurry and dark image was to use image controls on black and white or with the saturation at its maximum. I had already set a few points, that Dom said were good and now I must continue to make sure I can finish every task I signed up to.
