Let's make our own models (and maybe even animations)

In this context, I distinguish between level designers and modelers/animators/texture artists for the reasons mentioned above. Once again, briefly and simply: you can develop and demonstrate the skill of creating interesting and playable levels (level design skill) by creating interesting playable levels using assets created by others (models in this case). However, you cannot develop the skill of creating these assets by working only with materials created by others. To develop the skill of creating your own models (and, in fact, to become a modeler), you need to, surprisingly, create models. Why am I even explaining such an obvious thing?
