This week I started the composition of the second shot and fixed the problem that appeared in the previous shot. Besides the model material has been improved.
last week Nick suggested a few thins that need to be changed in the shot. When the robot rotates its head, there are several parts that stretch and deform. So this week I adjusted it.
I used the Blend Shape and sculpture tools to fix these problem.
here is the result after I changed.
Here is the final outcome. I also added some scratches to the texture.
Another problem is that due to the insufficient number of faces of the model, the surface of the model is not smooth enough. So I increased the subdivisions of the model to make it better.
In the second shot, I rendered different channels and adjusted them in Maya.
This week I made adjustments to the shadow and skin problems that Nick proposed. For my previous version. Nick thinks the character’s skin looks too dark. Compared with the surrounding sofa, the dark part is a little deeper. There is also the wrong direction of the shadow.
Here is what the shadow looks like before the change, which is completely wrong compared to the shadow of the sofa on the right. The correct shadow should be straight down.
So I re-adjusted the light source in Maya. Take the light in the right corner as the main light source and add another light under his feet to enhance the shadow effect. Afterwards, the color and blur of the shadows were adjusted in Nuke.
This is the effect of the shadow after the change.
About the modification of skin color. I chose multi-pass rendering when exporting from Maya. Afterwards, there are more possibilities for model adjustments in Nuke. For diffuse and specular layers, I added a Grade node to adjust the contrast and color saturation of the model.
Here is the result after adjustment.
