I am a Newbie to Blender.
My dilemma is that l have four sets of stairs as individual objects in a scene, with various other objects and when l combine all the objects into one scene/object, the stairs are integrated into the other meshes and disappear.
Is there any way of combining the objects without losing the stairs?
Screenshots of before and after joining objects. I have applied textures using Cycles render before joining the objects, is that the problem?
