Why can t the 3D rendering be black?

There are several reasons for this:

There are no lights set. At the same time, the default light is turned off when rendering.

If you're rendering an interior, you have to set up the lighting, even if you have a default light, which is usually not available in the renderings you need in an interior design (mainly because the default light is only for the outdoors).

The rendering angle is wrong (the rendering angle, if it is not set correctly, it is easy to render black, you need to choose the right rendering angle, it is best to set the camera to render).

You use any 3D software. Such as 3D MAX, MAYA, XSI. Modeling, adding materials, lighting.

What is displayed on the screen is the effect of hardware rendering. It's the effect calculated by the graphics card. But there are a lot of software effects such as fog, glow, bump, particle cloud, caustics, subsurface scattering, etc., that are the features of the software.

These effects are not visible for hardware vertex rendering, pixel rendering. Therefore, software rendering is required. The renderer is a piece of software in its own right.

It can be the default renderer that comes with 3D software, such as Maya, or it can be embedded in the software in the form of plug-ins. Such as Maya's mental ray, 3D Max's BrazilIt can also be stand-alone software such as Lightscape.

You chose the wrong view, or you chose the wrong camera angle.

Lighting issues cause 3DMax to render black, and all the lights in the rendered scene are turned off, including the default lights;

1. First open the software and enter the page.

2. Pull out two cubes at random

3. Find the render settings.

4. Find the common one and specify the renderer.

5. Select the V-Ray renderer.

6. The renderer was replaced with a V-ray renderer.

7. Find the global switch under vray, the default light under lighting, select tick, and choose to turn on global illumination.

8. Finally, click on Select Render, and you're done.

The 3D rendering is all black because there is no rendering light. Workaround:

1. First, select the object that is displayed in black.

2. Then add [Normal] to the object on the left side of the page.

modifiers. <>

3. In the parameter panel, it is displayed as [Unified Normal] and [Flip Normal], and select [Flip Normal] <>

4. After the setting is completed, the 3D rendered picture can be normal.
