maya材质最常见的莫过于金属材质和金属材质，今天再来学习一下用maya打造金属材质，希望朋友们喜欢本教程！
creation of a shot.
texturing
spending time in a story saves up work. letacute;s do it step
by step. first of all, weacute;ll do balance of which elements will appear on
the shot. i think a good way to begin is to define the position of the camera,
the elements that go in and out of its field of vision and the distance from
them to the camera. when the project gets more complicated with the construction
of several shots, a good method to be organized is to draw a story board. the
storyboard gives us the advantage of having a sketch of all the work that is
going to be done. in this case itacute;s not necessary as we are dealing with
only a shot, but it would be convenient to draw a sketch of it, even if
itacute;s just mental. one of the main reasons of having a sketch before doing
anything is to know what exactly we are facing, i mean which things have to be
created and which not. this is very important at work as that way we avoid
creating elementsortextures that are too detailed that afterwards are not going
to be appreciated because of the motion blur, depth of fieldorsimply because of
directing reasons (it even gives the chance to reach an agreement when the
result depends on several people). because of all that, is good to take a pencil
and a sheet and spend a few minutes to decide roughly which is going to be the
initial point to develop.
compositionorphotography of the shot. once we have the sketch of the shot, even if itacute;s only in our mind, itacute;s time to bring it to the screen. itacute;s at this moment when weacute;ll determine the compositionorphotography of our shot, by the placing, in our case, of the character in first term and the orb and columns of the background. there are some rules that make a composition effective and one that i often take in account is that normally we begin to examine an image from left to right. another important rule is not to place the main element of the shot in the center of the composition.
in my opinion, this composition, even without being too complicated, is effective. our sight goes from the left and come across the vertical and impacting figure of our character, to go on towards the right and relax with the orb and the blocks that form the background, that contain more horizontal lines on its shape. it is very useful to allow the software show us the resolution gate and the safe action frame of the camera, so we can decide in a precise way which are the margins of our shot. (in maya we find it in panel - view - camera settings) lighting is very important once we are moreorless satisfied with the composition of the elements, it would be good to do a study of the light . this is a fundamental step, because by it we define which is going to be the motif of our shot. personally, i have always taken into account that lights have the quality of modeling our environment, that's why i think that not paying attention to this step could decrease the aesthetic quality of the result. for example, in this case, the model was done in a very limited time, and was mission of light in that moment, and textures after that, to give it more consistence. with the lightning study is decided, among other things, the points of the composition from where light will flow and hit the objects giving dramatism and volume, hardness of the shadows of my sceneorwhich objects will shine themselves taking protagonismorweight on the composition. as the process goes on the result can de depured. the color is defined partially throw this step and it's a very important factor at the time of, for example, giving depth to the scene. there is a rule that works visually well when we establish the color theme; it consists on using hot colors at closer distances and cold ones further; it's just a rule but its orientative when we're producing our shot .
i chose, at that moment, a moreorless classical lighting, using three points of light: a main one (at right), a fill one and a backlight. as i had my character clearly separated of the background, i decided to use advantage of that situation by establishing by hierarchies, lighting for the background with its own set of lights, and another for the character. a technical advice : facing the light study in first place makes it less complicated later. the fact of having all the elements of the scene under a neutral color, such as gray, make light and its color take protagonism they demand at this point. also, lightning the scene with coherent intensities from the beginning allow to avoid problems later; i mean, with a so open software as maya, the range of different results that can be obtained is very wide, that's why constraining the values of some determining attributes such as light, makes the elements depending on light be under more control
working with layers : separating our scene in different layers and joining them together with a digital composition software has huge advantages, such as fine tune in separated parts the elements of the scene to get them integrated and look for the desired look.orhaving everything modulated so we can change anything if the client requires (in my case the glow of the orb), so we have not to render the other layers again. organizing a work in layers is fundamental if the look is complicated, as the 3d softwares don't allow many types of actions with objects ; for example, layer transfer modes.
