Currently some characters of the Han civilization in 0AD do not exactly show the style of the Han Dynasty. I have made several models based on the pottery figurines and stone reliefs of the Eastern Han Dyansty (25 AD - 220 AD), as I wish to bring the clothing of the Han Dynasty to 3D based on archaeological documents. I use Marvelous Designer for designing clothing and use Blender for designing the rest. I may offer clothing models. I cannot offer human models and materials as they are restricted by licenses. For human models, perhaps you may offer base human models, so I can adapt clothing to them. I am not able to make animation or skeletons. So if you need a character to perform a specific action, I am not able to do that. Some pictures of the models I made are attached.

Delenda Est doesn't restrict itself to the period 500 BC - 1 BC. This is why I am asking where do you want to create this thread because the framework is not the same. You seem to focus on the earlier periods of the Sarmatians.  And to explain a bit the confusion about the various nomads, it is due to different interpretation from ancient and modern historians. Herodotus mentionned different tribes related to the Scythians, for him it seems they were the same ethnical group. The same for the Persians who seem to have mentionned various Scythian tribes (called Saka by the Persians) which seem to correspond to a very large area and very distant tribes. So for them, the Scythians or Sakas were related. For them, the Pontic Scythians, the Sauromatians, the Dahae, the Massagetae and other Saka tribes were labeled under the same name. In archaeology, it is sometimes called 'Scythian phenomenon' to avoid using the term of Scythian culture.

Buenos día, tardes o noches; -Me refiero a hacer un foro como este (sobre los escitas) en la sección "Delenda Est" pero para los sármatas.La información sobre las dos culturas está muy mezclada.   Disculpen las molestias*

Thank you - will give a try
