What is the production process of commercial effect? Who knows?

First, modeling.

Example of scene model: room/living room/dining room/study room/doors and windows/ceiling/wall, etc.

Product model example: desk/desk/cupboard/chair/stool/sofa/coffee table/etc.

Examples of decorations: curtains/tableware/candlesticks/pillows/photo frames/paintings/pendants/porcelain/household appliances, etc.

Examples of lamp models: chandelier/wall lamp/downlight/spotlight/desk lamp/floor lamp, etc.

Second, the material/map

Material: Each model has its own surface properties, such as reflectivity, gloss, transparency, concavity and convexity of metal/stone/leather/cloth/glass.

Texture: the texture of surface properties, such as stones of various colors/fabrics of various textures/wood grains, etc.

Mapping coordinates: controls the rotation of the texture according to the direction of the physical texture, such as the direction of the wood grain is horizontal and vertical.

Description: The above part defines the surface properties of the product model, such as wood color, gold and silver foil, weathering, stainless steel, etc.

Third, lighting.

You can see the final renderings. Lighting is a very important part. Without lighting, it is black. There are many lights in a scene, such as desk lamp/wall lamp/chandelier/ceiling lamp/lamp belt/floor lamp, and moonlight, sunlight, skylight and TV screen lighting at night. These can illuminate the whole scene space and simulate the real space environment, light and shadow.

Lighting has directionality, intensity and color.

Fourth, the camera

A camera is equivalent to a person's eyes, and each rendering from different angles represents a camera, which is equivalent to a person standing in the position of the camera to see the whole scene.

Verb (abbreviation of verb) translation

Test rendering: When all models are set up and placed, the lighting layout is debugged, the materials are adjusted, and the camera settings are completed, the rendering of the low-effect thumbnail is called test rendering, and the purpose is to check whether the whole space is wrong, whether the lighting is in place, whether the materials are in place, and whether the camera angle is in place.

Global debugging: it is to adjust the test rendering results as a whole. After the mediation is completed, the test rendering will be performed, and the test rendering and global debugging will be repeated many times. When you are satisfied, you can render the picture.

Render a picture: draw the final large-size, high-pixel, best-effect picture of the test and debugging scene. This drawing process is generally slow, ranging from 2-3 hours to 5-6 hours. It depends on the hardware and software of the computer. (Hardware: The better the hardware, the faster the calculation speed, and the corresponding drawing time will be shortened. Software: Because 3D software and renderer plug-ins are too expensive, most of them are pirated. Pirated software has limited functions, unstable operation, and often shuts itself down during rendering, resulting in the previous work being wasted. For example, the renderings of Shanghai Scissors and Stone Cloth Shop, in the production process, the software shut itself down more than three times on average. I don't know whether it is hardware or software. ).

Sixth, post-production.

Graphic software is mainly used for color matching. In the early days, ornaments and flowers were mainly added to the renderings, and trees and sky backgrounds were added outdoors. Now full-mode rendering technology is basically popular. It is difficult to achieve real three-dimensional sense, depth sense, surface texture and light and shadow projection in plane processing. However, full model rendering can solve this problem. The plane software needs to process the material map in advance, and sometimes it can't find a suitable map or color, and the size is not suitable, so the plane software needs to process it first. In addition, if you don't understand, find a wise way.
