The best thing about FLIX3D is its user-friendly interface & easy navigation through different tabs. I've been using this software for years now & have never faced any technical glitches or issues in my continuous work flow while working with this tool. It's definitely worth it! There are no downsides as far as i'm concerned. This product has helped me tremendously in improving myself as an artist. As mentioned earlier, the most useful feature about FLIX3D is that there are so many options available under one roof which makes your job easier than ever before. You can use tools like color picker etc., without having to download additional plugins separately. Also you don't need to learn another coding language such as HTML5/CSS3 as FLX3D offers all those features within itself.
