I have created this coastal defense proof of concept to see how AI reacts to it or any enemy. I have saved the game. Feel free to use it and comment if you want. It is done with the Roman civilization.

Hi @Mar.x, welcome to the forums. My only guess would be to try Vulkan as renderer. Your logs could be of interest. https://gitea.wildfiregames.com/0ad/0ad/wiki/GameDataPaths

I just installed 0 a.d. and have a problem with the graphics. The units are practically see-through, only their weapons and headgear are visible. My system: Lenovo Thinkpad T450s Video card: Intel 5500 I searched this forum and didn't find any hints, I also tried different graphics settings, but nothing helps. Any advice?  

@Duileoga Here is some interesting info for your mod. This is from the Wiki page about South Slavs, not sure how accurate "Jordanes (fl.  6th century CE), Procopius (c. 500 - c. 565) and other late Roman authors provide the probable earliest references to southern Slavs in the second half of the 6th century. Procopius described the Sclaveni and Antes as two barbarian peoples with the same institutions and customs since ancient times, not ruled by a single leader but living under democracy, while Pseudo-Maurice called them a numerous people, undisciplined, unorganized and leaderless, who did not allow enslavement and conquest, and resistant to hardship, bearing all weathers. They were portrayed by Procopius as unusually tall and strong, of dark skin and "reddish" hair (neither blond nor black), leading a primitive life and living in scattered huts, often changing their residence. Procopius said they were henotheistic, believing in the god of lightning (Perun), the ruler of all, to whom they sacrificed cattle. They went into battle on foot, charging straight at their enemy, armed with spears and small shields, but they did not wear armour."

Duileoga is working for a mod. Don't worry, there is little chance they would be integrated in the main game. The Chernoles culture disappeared a long time ago, around the 6th century BC. The Milograd culture existed in northern Ukraine and southern Belarus for several centuries. But it was replaced by the Zarubintsy culture, which represents a bit of a cultural break. There are elements of the Zarubintsy culture that originate from Germanic cultures. This culture of Zarubintsy appeared around 200 BC and existed up to the 1st century AD. After that, there is a transition period when the culture of Zarubintsy decays and a sharp reduction in the number of settlements. The Kiev culture is a reemergence of a Balto-Slavic culture which appeared around the 3rd century AD. The question of the Slavic origin is tied to how the Kiev culture appeared.  If you want to portray the Venedi/Veneti, they are probably further in the North. Pliny and Ptolemy locate them near the Baltic sea region. So we can suppose the Venedi/Veneti were a confederation of different Balto-Slavic tribes. Generally, the Brushed Pottery culture, the Milograd culture and the Dnieper-Dvina culture are seen as a continuum of similar populations. So if you want to suppose the testimonies from Pliny, Tacitus and Ptolemy are also valid for a more ancient period, then you can suppose these cultures were related to the Venedi/Veneti. Like this you can use evidence from the Milograd culture, Dnieper-Dvina culture and Brushed pottery culture.  And you can add Germanic mercenaries from the Przeworsk culture (Lugians) and from the Zarubintsy culture (probably the Scirii). You can also add Sarmatian and Scythian mercenaries.
