3dmax is mostly used in game modeling, parts design, real indoor renderings and other industries. Through modeling, adding materials, mapping, rendering and other processes, a realistic scene is produced. The use of 3dmax software is also difficult. If you want to teach yourself 3dmax, you can see Yutu. There are various tutorial courses on the use of 3D software. Learning from teachers can help you get started and master this software faster. For this reason, many professional 3dmax courses are provided, including indoor rendering, the use of VRay renderer, the introduction of basic knowledge of 3DMAX software, the use of 3DMAX software and other professional courses. If you want to teach yourself 3dmax, you must not miss it.

3DMax's tutorial on simulating sunlight and skylight with VRay illumination.

Next, use the idea of lighting to operate. First, arrange a skylight.

Then press the F key to enter the front view, and we will create it with reference to the size of the area.

Simulate lighting from the outside, enter the creation panel, then enter the lighting, and select VR lighting.

Now it's a spherical lamp,

Change the type to plane,

Then create a light with reference to the size of the door.

At this time, press the T key to enter the top view. Let's see if it's in the right position. We use the move tool to adjust its position, and then mirror it along the Y axis. After mirroring, we will adjust it to enter the modifier. Let's look at its parameters. Multiplier 30 is too strong. Set it to about 2. Of course, the settings here should be adjusted according to the size of the surface light and the needs of the scene. If it is small, you can set the multiplier value to be small.

This lamp simulates the skylight, so it should be blue. Just give it a light blue. Check one or two invisible ones below, and uncheck Affect Diffuse Reflection, so that the reflection effect inside will not be affected, that is, it will not be reflected inside. We can check Affect Mirror Reflection and Affect Reflection.

Next, by copying, hold down Shift to copy a copy to simulate the surface light of this place. The advantage of copying is that the parameter does not need to be adjusted repeatedly, and the multiplication is unchanged, but its size can also be changed by scaling.

We click F to enter the front view, and then zoom out from the Y axis, thus forming the effect that the light comes in from the outside and gradually weakens.

This is more in line with the laws of nature. We need to simulate sunlight. We adjust it with a faint warm color. If the mediation is not accurate, you can write down the parameters.

This part of light is set.

We press the c key to enter the camera view, and now we can render. When we actually create a light, we have to perform a rendering test every time we create a light. Suppose the rendering test is turned on. This is to simulate a skylight. If we want to see the effect quickly, we will set its size a little smaller, and the ratio will be set to about 1.05, so that the whole picture will be more complete and coordinated, and the conventional picture ratio is 65438.

Where the rendering is good, it is obvious that the whole scene is illuminated. This light has a state of cold and warm contrast, and this light is still relatively natural. However, we can see that although there is ambient light, the lighting at the top of it is still not enough, and the visual center focused on it is not very rich. We also need some light embellishment and main light irradiation. If these lights are not enough, we need the main light for lighting, so that we can turn on the lights.

That's why some people don't understand why we want to create a daytime state and why we want to decorate it with lights. This is our skill in making renderings, mainly to enrich the effect.
