Mount & Blade II: Bannerlord Modding Kit now has a "Beta" version which can be enabled in the same way you enable "Beta" for our base game. IMPORTANT: The base game version must match with the modding kit version in order to work properly. For example, if you have your base game on the latest Beta, then you must also switch the modding kit to the latest beta. You can enable beta by right-clicking on Mount & Blade II: Bannerlord Modding Kit in your Steam library -> Properties -> BETAS -> Select the beta from the dropdown menu.
We've added 3 skeletons (human, horse, camel) to the latest Modding Kit Beta. You can find them in the "ROOT/modding_resources/skeletons" folder.
