This week we looked at clean up on Nuke, where you can remove things from a scene using roto paint features such as clone. Roto paint offeres more features than the normal roto node, such as clone, blur, and paint. First, we looked at adding focal points to an image. We added the defocus node on to an image of helmets, and we moved the focal point around the image as the focus changed when we did this.
We then played with the roto paint node, with the paint option, allowing you to paint anywhere on the scene. On the same node, we can select the blur option, which in it’s name, lets you blur areas of the scene.
We then looked at cleaning up a scene using some of these features. We were given a scene of a school hallway with posters and drawings on the lockers, and papers on the moving because of the breeze. We were shown various clean up methods such as the fire escape sign being taken out of the shot, the poster being taken out, and also text being added by perspective and trackers on the raidiator. The clone tool was used to remove the things in shot so I wanted to try this out.
We were asked to remove an element from the scene so I chose a drawing on the side of the locker, and used what I had learnt about the clone tool to blend in the removal of this drawing with the rest of the locker. I placed a framehold node then tracked the shot.
Work from home
We were asked to add something to the floor to this scene for homework. My immediate thought was something that had to do with school, kids and playing, and also a floor: the floor is lava! I thought this would be fitting and a fun element to add. To do this I rotoscoped the entire floor, planar tracked it, added stabalize to the roto and also corner pin absolute. I also remebered to add perspective using the grid lines to this planar roto. I then added my image in to Nuke and merged this to the original scene.
I then rendered this out.
Our next task was to finish our Balloon Festival Project. I had nearly completed this already but I wanted to add some more elements to it. I figured if I had the dragon breathing fire on the balloon I should have the balloon catching fire. I added the same fire png file and transformed this to follow the balloon using keys and also scaled it to size. I then added the dissolve node so it appeared at the correct time. I then wanted my balloon to be shown more in the project so I added another one of the balloon model coming in at the end above the roto of the mountain, in closer perspective. I transformed this and then used keys so that it moved to where I wanted it to move. I then added a low opacity filter to the background by funsing a dystopian sky png image that was transparent. I added an opacity node that someone had created online after researching, and it gives the scene a slight orange and red tint to it.
I then rendered this to upload on here as my final scene.
