But there are problems with the picture; they are bright and Viewer 1 and 2 have the same image. Let's try to understand. We need to change all the Read color space nodes from Linear to sRGB. And in the Merge node, change the operation from over to plus, which is default, because, according to the formula, these two passes should be added (Fig.26).
Now everything is arranged, and we can continue. In order to have access to the settings of any node, we must double-click on it and then on the Node Graph. Then, on the right-hand side, on the Properties tab a window for editing the parameters will appear. By default, we can simultaneously have 10 open windows. However, we can change the number by changing the number from 10 to the desired number, or close them all by clicking the cross next to the figure (Fig.26).
Here are a couple of more tips. According to the standard setting, Ctrl + Z brings you back one step, in the order that the steps have been taken. In each node, as you can see in Fig.27, there are icons that take you back a step, forward a step, or return to the settings the file had when it was originally opened.
Nuke with OpenEXR files, obtained via V-Ray, works slowly. We can resave them through Nuke in OpenEXR, which will speed up the rendering process in Nuke. Scrolling on the mouse zooms in and out, and if the mouse is pressed it can be moved in all directions.
Another useful shortcut (D) makes the selected node inactive. For example, we have applied a color correction, and we want to see our image with and without effect. Select a node and press D to make the effect inactive, then press D again to make the effect active again. Add Refraction and Specular passes, like the previous ones (Fig.28).
We do not have Self Illumination from the formula, so let's move to Ambient Occlusion, also connecting this to pass, but with the Multiply operation. I lowered the impact of Ambient Occlusion a bit with the Mix slider by putting in a value of 0.9. The slider is at the bottom of the Merge node. We must only add Reflection with operation set to plus. And with this the Pontiac is almost ready. It only remains to add RawTotalLigthing with the operation set to overlay and a Mix value of 0.6 (Fig.29).
