P40
sketchfab
I'd love to help you out. Let's focus on downloading a tank model that's light enough for your needs. Since textures can be quite heavy, we'll stick with the basic model for now. Have you checked out the group VK at vk.com/sere7? They might have some great resources available. And if you want to connect with me directly, my profile is on VK at vk.com/miunodev.
