The latest release of Echo dot.
PBR textures include: One baked texture map for Bump and Transparency ( for the object called 'up', which is the part of the model with little holes)
PBR texture size:2048 *2048
format: FBX, OBJ and DAE(Mesh only, but they all have corresponding materials that you can easily replace) and also Cinema 4d project file(with the same render setting as the thumnails)
For the texture to work, Please make sure to connect the texture to both Bump and Transparency, and the color of the base model is also very important
Only the part with little holes is UV unwrapped
