So today I was doing roto and had a meeting about silhouette rendering. I also had a meeting with using silhouette itself. So you would set up the plate as you would in nuke and put in a silhouette node. For the input the node system is like Houdini and you pipe it in to the green part of the node. So what it was doing before is rendering out each layer which took forever to actually get it. So instead of that we are going to put all the roto into one master layer instead then copy out each individual layer for its own copy. Then with all the different layers you would put them into a output multipart which is an node for multichannel of roto. So you break up the different layers of roto to objects and delete the ones it's not apart of and make sure to label each layer of roto. Then, on the multipart output you right click to add more inputs for each layer. Then, when you render make sure it's on alpha and you put it in the right file. Once rendered you and read in the rendered version but it would look like nothing is there but you can just check that all the different layers are there by checking the layer break out node or you can get the layer contact sheet node to check as well. Then, you shuffle out each layer and then merge it altogether. To duplicate nodes in silhouette you press CTRL + D but to paste it's the same as CTRL + V. Also to align nodes in silhouette you just drag and right click then click arrange then align to make the nice and neat. You plug the plate into the foreground and output for the node is underneath the computer icon in the grey. For now we are having to create our own folders and you have to make sure you are using #### for it to render properly. Now for the actually silhouette training you would open exactly as much make sure if you are doing paint work you put it on paint or if you are doing roto you put it on roto. You would pipe the plate into input and not into source 1 or 2 as this acts like the paint tool and brings in the sources into silhouette. So when you first open the node it will come up with a new project window. It's best to go into nuke and get the script name and copy it into the folder and manually put the name in. So you make the silhouette folder and in this folder you have images, render and scripts. Select the scripts folder so it will create everything in that folder. The object list is like the layer list in the roto node in nuke. It's best to cache the plate by playing through it once. The blue screen is what I am viewing. 1, 2, 3, and 4 is different views like in nuke but for foreground E.c.t. It's best to always view everything in foreground. Pressing T cycles through all the transformation tools you can use in silhouette. Once you click the point transformation after selecting points you can move it around more flexible. If I'm output and moving shapes it will be more laggy. When viewing alpha it needs to be viewed in output otherwise you won't be able to see anything. Press A to see a blue overlay. 4 is a colour composite is like using a inverted premult node so you can see what's inside of the roto shape. If you press O you can see or hide the overlay. CTRL + Click + drag changes the brush size in the brush reshape tool. Select layer + shift + T to bring up tracker in point track is exactly like the tracker in nuke. Planar tracker is drawing a shape to track a bit like mocha. But you can also use mocha tracker as well. The transform matrix is like keyframes in nuke A.K.A. Node graph/curve editor. Shift + Click and delete to deleted tracks. Motion blur is actually in the node setting. You can change the shutter angle or phase. 16 samples is best for working as it won't lag that much but for rendering its best to use 64 as it looks cleaner. But for the shutter angle or phase it's best to ask your supervisor what it is. To enable it on the object go to the object list and click on the 3 boxes icon. Invert it in a new layer if you wanna cut off part of a shape if it's not what you want to see.
