At present, designers of decoration renderings generally use professional software such as 3dmax and vray. If there is no foundation, you can use Aifuwo online decoration design renderings software, which is very easy to use anytime and anywhere. Very convenient, you can also switch 3D views and make renderings, wallpapers, floor furniture and so on in minutes. You can use it by dragging it to the floor plan. It's very convenient, and there will always be satisfactory results if you try more.

If you are making a decoration renderings, then I think three points are very important:

1 The light is very important, and the exposure of lighting and reasonable renderings of doors and windows will be normal.

2 color matching is very important, and it is best not to exceed three color systems, except for small ornaments.

The angle of "photographing" is also very important. You can make up some photography. Sometimes shooting the same scene from another angle is very different.

To achieve the above three points, I don't think the renderings will be too bad. Good luck.
