Hi.

I tried creating a sofa based on the ultra popular Nyan cat. When I placed it in game, it looks fine when you zoom in, but when you move the camera and zoom out, it's texture is replaced with the original.

I used Object workshop to clone a sofa, then recoloured it and pressed "Import" and commit.

Did you right click on the texture in the TXTR and select the "Update All Sizes" option? If you are using the NVidia DDS Utilities, you get better quality and the sizes are updated automatically.

I mention this just in case, but make sure every OBJD has a new and unique GUID.
