First of all, the most basic and important thing is photoshop. There is no doubt that this software is essential as long as you are engaged in this industry. Even if you are engaged in 3D work in the future, drawing maps and other work needs to be done in it. Another is Illustrator (or CorelDrow), which specializes in drawing vector graphics. In addition, what we have learned is comprehensive and miscellaneous. We also learned Dreamweave (the person who makes web pages); Flash (for two-dimensional animation); 3D MAX (can do 3D animation, interior design, etc. . Very powerful); AUTO CAD (it is more convenient to draw architectural drawings and do some decoration effects with 3D max); Premiere (video clip); After Effect (video special effects production) and other software.
In fact, we mainly study photoshop, 3D MAX, PR, AE, AUTO CAD and so on. . Personally, I think it is promising to learn 3D interior renderings well, and I hope to earn more money and find a good job, which will help you.
In addition, we attach a screenshot of the software we have learned for your reference.
