I am in the process of trying to work on some shaders for my thesis project. I have created a pinball machine. Everything has gone well up to this point. I created a glass shader using different methods and ended up with a Mia_Material_X. I feel the glass is feeling realistic and I realize that glass has some bluriness, yet when you look through the top into the machine there are blurry areas where I feel it should not be blurry. For instance, over the typography at the top of the machine (see image). I realize I can increase the samples in render but I think that will really bog the machine down.
Also, I created a pinball. The ball was also created with a Mia Material X. Only problem is it needs some scratches which I attempted to create using a bump map. Doesn’t work. I was thinking of trying an anistropic material and using the recipe for brushed metal where I could possibly turn down some of the scratches and maybe increase specularity? I am also uploading an image that shows my progress thus far. I am thinking if I cannot get the scratches to work in Maya I may have to produce them in-post using Nuke.
Any suggestions would be very helpful Suzanne
