Well why didnt you ask that in firstplace.
which oscillates at a frequency to match the frame rate
Means make a displacement map thats for with any procedural 3d texture that repeats itself each frame, in other words its keyed to do animation cycle in one frame.
One 360 rotation per 25 frames?
one rotation per 1 frame. Tough it hasnt got to be a rotation it can also be a spatial shift just as long as it repeats.
For example make a volume noise, key roation of it to be 0 at frame and 360 at frame 1 then set the curve to post infinity cycle.
Also his 'procedural bump map' is with what texture? I
Depends on what effect you want in this case it looks to be a u stretched perlin noise, they dont say. What they want si a texture that looks like grooves in some direction to make it look like theres brush strokes.
I'm not sure how to apply the other settings that he talks about, to get the brush strokes. Luminance gradients in Maya?
Its called a ramp, you can use a any of the ramps or then you can use the ramp shader.
Now motion blur sampling in maya works a bit different form lightvwave... so you need a bit different workflows.
Hardest part is normal maya shaders dont animate displacement frame form frame, thsi is where it gets tricky. YOu will nee dto make the displacement in cgfx shader and use maya hardware to render this. Or you can chaage the mentalray shader a bit. However the far easiest is to render the animation with 0.2 -0.1 frame increments and in comp average the sub frames toghether.
Or you can bake the mesh out and blend your choice really.
I know I could play around with the various built-in options within
Mayas materials, but I would really rather not waste an awful lot of
time playing with things like that. Playing only gets you so far
Playing gets you very far, if you never play you will never be able to crack your own ideas open. Thats the only thing that counts, even a halfbrained 8 year old can follow step by step instructions, only people who are willing to play can do the rest*. Rather the real trick si to adapt data, and fast. YOu can only get there with certain amount fo practice and philosophical thinking into your art or rathter gongfu.
I mean i know how to build my own electronic devices, but i dont since it takes me ages to get anywhere, a experienced electronics designer and tinkerer literary gets in day where i get in month. Does not mean i can not do it, or havent done it, but in the gneral sense of thins people would call me not able to do it because i'm so slow at getting there its next to useless.
^the problem si that in conversation poeple usually dont have time for the full explanation. So you need to be equally knowlegeable and fill the blanks.
