Based on Baneling Concept Art from Starcraft 2: https://starcraft.fandom.com/wiki/Baneling/Development
This is a zerg egg I made while playing around in ZBrush. I retopologized and unwrapped the uvs in Maya, textured it in substance painter with my mouse (because my drawing tablet broke), and then rendered the low poly model in Unreal Engine. I would have liked to tweak the green "egg sack" portion of the texture to make it more transparent, but my hard drive died and I lost the files. Remember to make backups!
