What I am trying to do is have two cup models with two liquid models for a desk decoration. The problem is that the liquid models aren't displaying their textures as they did in Blender. Open the included file in GZDoom/Doom2 : "liquid model not displaying.zip". Jump on the desk to see the top of the liquids. The model on the right is the liquids themselves only. The liquid models were created using the boolean modifier in Blender.
