PHOTOSHOP and seamless texture

Whether three-dimensional design, or web production, or advertising printing, the use of seamless mapping is clearly more broad. Some filters are designed specifically for mapping, but I always feel inconvenient to use. With a filter of any special tools or other disadvantage is that I lost control of texture. Making a map, you always some specific considerations, especially when the raw materials used to make Tietu can not have Tietu conditions, is likely to make people know what to flawless.



In fact, when considered carefully, making a seamless texture, is not difficult, can in Photoshop in hand. Let us consider the time when the application of a seamless mapping, site maps will be seamless in the vertical and horizontal, with the right image on the left butt, and below and on top butt. This is obvious. The problem is just butt on them. Do you think a problem? Not at all difficult. Look at the picture above, we will cut the left part, then move to the right, then the rest will be left to the right edge of the natural post-docking on the narrow edge completely. The remaining question is how to make the move to the right of the narrow and the whole image fusion.

To let you see clearly, I put the right point that narrow slightly raised, and made a shadow. They certainly are not the same level, the narrow pressure over the entire map, and a considerable part of the overlap. First to narrow and align the whole map, if necessary, to enlarge these images.



Now let's look at this piece of partial image is above the right half of the entire map. But has been aligned. The middle vertical line is clear. The reason for a considerable part of the two images overlap, is to now be able to use the eraser tool to erase. But you have to be patient, choose the right size rubber edge virtual technology and transparency, do not click on the rub, according to the specific circumstances of images, carefully remove the unnecessary parts. I suggest you just erase the top layer, which has just moved over from the strip. Remember that the entire map layer below the edge position, the eraser will not leave it too close, otherwise this edge will be more clashes. Some places, very close to the color, it is simply removing a little sideline.

Sometimes, the images left and right or up and down is not the same bright. You may need to adjust prior to the image as a whole, with a mask to make the transition options, and then adjust the brightness, contrast and hue saturation. Can sometimes still can not move over the narrow harmony with the whole plan, especially the seamless, it is easily seen. It is recommended that you use Photoshop on the toolbar that black mask, looks a bit like a magnifying glass, but black. It could be used to clean the place to light up. Press and hold the button pressed, will pop up tools, there is also a hand-shaped pattern of the button, the role of the contrary, it makes images darker. Of course, you have to pre-selected brush size, edge virtual technology and transparency.

Seamless production of about completed, will merge two images, then use the same method of making a seamless whole production.

Do not be too care about the details, seamless texture, in most cases is used for shading, completion of seamless treatment is often adjusted to a very shallow level, details are not important. Even as a three-dimensional maps, not to their tune very shallow, you have to take into account the texture map should not be detail design is to prevent an overall sense of three-dimensional objects. Mainly to note changes in color can not be too obvious, is not a strong feature of the change, or will cause significant duplication of flu.



If you do not trust the work yourself, you can try. Is to select it, Copy, and then implementation of the Edit menu of the Define pattern, then, to a new plan, bigger, do Edit>>> Fill, and pop-up dialog, select the Use Pattern option.

Shading your attention to this page yet? Is to use the site map for, of course, I put it up too shallow, and added a point of filter effects. Used here is not beautiful, just an example Bale.

3DS MAX and some basic materials and practical examples of parameters

The following are some I use the max material in some of the understanding, here for reference only, imperfections like to point out, though not comprehensive, but I believe you have to help.

Material types explained

Start MAX, press the M key keyboard, in the Material Editor dialog box pops up, in the lower left corner of the window material ball get Material button click, pop-up Material / Map Browser dialog box, shown in Figure 01.



Figure 01

1: advanced lighting override (high light material) - this material is generally used with light transmission, rendering time can be well controlled light transmission and reflectivity between objects.

2: blend (fusion material) - two different materials together, according to the different degree of integration, control the display of the extent of two material can be produced using this material deformation characteristics of animation, also can specify an image as a fusion mask mask, using its own gray value to determine the degree of integration of two materials, often used to produce more sophisticated texture objects, such as polished marble, Poqiang, dirty floors

3: compositors (synthetic material) - his function is to add together a number of different materials, including a basic material and 10 additional material, by adding, removal, and mixed to create a complex and diverse material objects, often used to production of animal and human skin, rusty metal, rock and other objects of complex materials.

4: double side (double-sided material) - positive and negative for objects or surfaces inside and outside the two different materials are specified, and they can control the transparency of each other to produce special effects, often double-sided display objects in a number of different needs material animation, such as playing cards, cups, etc..

5: ink'n paint (ink, paint or cartoon material) - cartoon material, black and white over gray is not so soft.

6: matte / shadow (hidden projection material) - it is the role of hidden objects in the scene, rendering can not see, will not block the background, but can also produce other objects block the acceptance of its projection and projection effect, many only see the projector can not see the animation object can use it to make.

7: morpher (deformation texture) - with the morpher modifier to use, resulting in material deformation animation integration.

Is the different textures and colors mixed treatment, so that they become a map.
(1) compositors (synthetic) - multiple textures together, by mapping their own alpha channel, or output amt to determine the transparency of each other.
(2) mask (mask) - use a map as a mask, gray by mapping the size of their maps to show the material to be masking effect.
(3) mix (mixed) - mixed with two kinds of maps, by adjusting the number of values to produce a mixed result of the fusion with each other.
(4) rgb multiply (rgb multiplier) - the main way to cope with bump mapping, allow two colors or textures multiplied color processing, to increase the image contrast.

4: Color Mods (color change map)

Figure 05.



Figure 05

(1) out put - output - designed to set up some non-output mapping type.
(2) rgb tint - rgb coloring - through three color channels to adjust the map's colors, eliminating the need for us in the other image processing software processing time.
(3) vertex color - vertex colors - for editable grid object, it can also be used to create color gradient effect.

5: Other (reflection and refraction of type map)

Figure 06.



Figure 06

(1) flat mirror (mirror reflection) - for a total simulation of the surface plane mirror reflection effect, with the use of reflection mapping.
(2) raytrace (ray tracing) - to provide real full reflection and refraction, but longer rendering time.
(3) reflectrefract (reflection and refraction) - with the reflection, refraction maps generated using reflection, refraction effects, faster, can be used for animation.
(4) thin wall refraction (thin wall refraction) - with the reflection map used to produce the refraction lens distortion effects, speed, used to make glass and a magnifying glass, produce more realistic textures.


Here are some of the production method and material parameters (this is a living)
Note: - The delivery layer

1: broken roof

Using blend materials - transition zone - the exchange of the region - by adjusting the value to control the shape of the curve, when the two values close to, the texture of black and white transition zone will have a clear sharp edge integration, otherwise the integration of a fuzzy edge

Material 1 --- diffuse - noise mapping - color1 - dark brown, color2 - dark yellow size - 20
bump - noise --------- amount - 690 - strong bump
Material 2 - fill the first of the pit, but also effects the performance of crack
diffuse - noise - color1: dark brown, color2: beige, size: 3
bump - marble - black, white --- 40amt
Fusion Set: mix amt: 70

2: The column (vertical bar with the texture and the corrosion effect of cement dust column)

compositors
Basic Materials - Cement mapping
diffuse - noise - color1: gray, color2: white size: 8
bump - noise - black, white size: 2. 3
Vertical bar textures - Additional Material 1
diffuse - noise - color1: dark brown, color2: lime green
opactiy - marble - color1: dark gray, color: light gray - to achieve exposure through a transparent texture
Vertical bar texture, while the basic materials will be displayed
Dust and corrosive material - Additional Material 2
diffuse - noise - black, gray, size :50 ---- performance of dust
bump - smoke texture - color1: black, white size :10 --- performance corrosion effect
Synthesis parameters ---
Additional Material 1 --- 98 --- 46 Additional Material 2

3: wall (with speckle texture) - carved in the wall with moss

diffuse - specle mapping - color1 - dark green (moss) - color2 (with the dust of the wall): Default color
color2 - noise - color1: Black color2: light brown
bump - texture pattern of the bitmap

4: floor (splat) on the floor covered with dust and dirt

diffuse - splat - color1 - wood texture - the basic material
color2 - noise - black, dark green - the soil dust
--- (Add a bump map to the soil part of the bulge will be more true)

5: covered with gold dust relief

Reflective mode - metal, reflective intensity - 160, smoothness - 31
diffuse - gradient ramp - yellowish - Dark Gold - more yellowish (corrosion discoloration of gold) is also used as a stone
bump - the golden image map
Since the light texture - the golden image map (better reflect the metal outline of light relief)
--- Otherwise, add noise maps can be, or variable blend material with metal scratches

6: Corrosion of metal
compositors synthetic material
Method: You hand the corrosion of metal materials there, and then use additional materials to the performance of corrosion (through transparent textures)
Basic Material: strauss, 97,20
diffuse - noise - color1: dark red, color2: light dark
Additional material: strauss, 87,60
diffuse: corrosion off a bitmap image
opaity: splat

7: The moon (which can be looming in the animation)

top-button material
top material - moonlight - from light yellow for the month
button - the transparency to 0 (to display background reflect the moonlight effect)
Adjust the edge - blend :23 - position: 46
These two parameters can be adjusted to achieve animation effects
At this time the moon is up and down direction, to read about the election should be in the material coordinates in local mode
Moon then you can rotate the scene

8: water drops

Reflective type - phong-smooth high-light area - glass, plastic, etc.
Reflective Intensity - 72
Smoothness --- 48
index of refraction --- 1.33
Specular Map - raytrace - Background color - dark green - instead of the environment, fast rendering - amt - 60
Refraction texture - thin wall refraction - refractive effect produced between objects

Some of these materials is only about the introduction, in practice, we should slowly try to integrate the scene of the parameters.
