Final answer:
A 3D animation expert should ensure their new computer has a powerful processor, sufficient RAM, and a dedicated graphics card.
Step-by-step explanation:
To handle demanding software, a 3D animations expert should ensure that their new computer meets certain requirements. Firstly, they should make sure that the computer has a fast and powerful processor, such as an Intel Core i7 or i9, to handle the complex calculations involved in rendering 3D animations.
Secondly, a sufficient amount of RAM, such as 16GB or more, is necessary to store and process the large amounts of data required for rendering. Lastly, a dedicated graphics card with good performance, such as an NVIDIA GeForce RTX or AMD Radeon RX, is essential for real-time rendering and smooth playback of animations.
