Converting 2D into 3D and decorating the icy model into vivid and realistic objects, the function of model mapping is quite powerful. To say the highest level of model mapping, it should be the photo level. So how can I post a realistic model work like a photo?
Metal textures can be said to have a large weight in conventional textures, and are one of the textures that we use very often and are relatively easy to produce. Although there are many types of metals, our means of expression are limited, so we must have a clear idea to express the properties of props.
First, we categorize the metal properties that are often produced in production:
1. Warm and cold, light and heavy metals. In the production, some instruments or spaces that are more high-tech feelings often choose metals with a cooler color. Among them, the proportion of light metal is large, there is no dirty rust, the texture is smooth and delicate, and the details are expressed by some precision parts. Heavy metals give people a feeling of being bulky, such as engineering machines, factories, heavy weapons, etc. These have more common tone performance, such as militarized things use more green; civilians tend to yellow. They can all make more fuss about the old, because of the long-term stripping, large dirt and so on.
2. The relationship between paint and metal. Metals and paints are inseparable integrals of our metallic properties. Unpainted metals such as stainless steel, aluminized, gold and silver, we are more aware of the whole and reflection. The metal is covered by paint, and because of age, wear and tear are the details we have to master.
Here, two things can be separated: the first one is paint peeling off, the metal is exposed, the wind starts to rust after the sun is shining, the iron rust red to yellow can be changed, and the copper rust is greenish. The nature of the metal itself. We don't need to master everything. As long as we master the basics, we can make the details natural. The second type is paint shedding, but because of the short time and uninterrupted wear, the metal is not corroded and the performance is very bright.
3. Intrusion of other element materials. The other elements here can be everything, such as the paper scraps left after the poster is torn off; the dirt on the bottom of the vehicle; the blood on the edge of the knife, and so on. In addition, Logo and text are also important parts. Different logos, the atmosphere of the text and the use of the production items, etc., are all applicable in the specific production, and they should be considered as elements for all textures.
Next we will make an example that takes into account the above situation.
First find a suitable texture, do some basic adjustments, do it in the middle, and then find a lacquered texture. Note that in combination with the model observation, if the texture is not suitable, it is necessary to perform the scaling process, find a suitable superposition method, adjust the color gradation, transparency, and the like.
Start making changes, adding details, all using existing resources to merge processing. The method is still the same, copying the desired details, multi-layer overlays, modifying the excessive edges and paying attention to the effects.
The rust is now messy and needs to be sorted out. Imagine this is outdoors, and the rust should have the same effect as the water flow after prolonged exposure.
We only need the white area, select it with color, then copy the rust map correspondingly, select the overlay method, and give a suitable inner shadow in the layer properties, so that it looks like it has the effect of being wrapped by paint. Some details have been adjusted.
Add some icons or logos to show the effect or personality of the object. If you want to make a poster on the object you are doing, you can do some torn paper scraps next to it, which is more convincing.
Pay attention to the edge of the poster, you can use some black and white mask to make the tear-off effect, which is more real than using the rubber, of course, some details need to be repaired by the rubber tool. Pay attention to the layer's retention, because you will need to modify the details when doing highlights and normals later.
It's not hard to see that if you want to make a texture that is very realistic, you need to observe life more often, as well as patience and care.
In order to let everyone have more reference, the following is a review of the work of the blue pencil advanced game model class. The teacher Tian Peng is a senior CG model teacher, an expert in animation, specializing in professional 3D software such as MAYA, ZBRUSH, UVLAYOUT, etc. Teaching students the essence of 3D model creation, teaching students to analyze effective methods of model making, so that students can independently model and improve work efficiency.
Teacher's comment: This work is not very good for the rust, you can be more delicate.
Teacher's comment: The rust in the middle of the gas tank is too regular, and there is no rhythm change. Gas tanks in normal life should not be so regular during use, and the bottom of the process should be dirty and stained. The rust is only in the middle part, and the treatment is not very good.
Teacher comment: Although you put the teachers' avatars on, but some small places are not very good, for example, the texture of the aluminum material at both ends is not very good, the other overall is not bad, the effect of specular reflection is too strong.
Teacher's comment: The production of this seamless texture floor is still very good.
Teacher's comment: The overall feeling is good, no matter the effect of specular reflection and the effect of aluminum products, the only downside is that the aluminum products on the color map lack texture.
Teacher's comment: The edge of the banana is too strong, the handle on the pear is too big, and the overall should be slender.
Teacher's comment: The top surface of the oil barrel is too strong, the rust rhythm at the bottom is too small, too regular, and the other overall feelings are not bad.
Teacher comment: The model part is good, but the layering of the texture is not very rich, and the details of the texture can be more abundant.
Teacher's comment: The overall view is good from the texture and effect, but the scratches of the shell can be more abundant, and the wear of the box mouth and the wear of other parts should be significantly different.
Teacher's comment: Some wear on the edge of the box can be more abundant, the texture of the shell is well done, but the effect of specular reflection can be slightly weaker, and it will be better to modify it in this respect. Overall it is still a good work.
Teacher's comment: Some details on the color can be more abundant. The color in the middle of the worn place and the place where the paint is too much is not very good. The place where the paint is worn off is not very good, and it can be done better, but inside. The texture of the shells is very good and works well.
