Hello Unity3D.I have a little problem with importing models into unity3D. Everytime i reimport a model into unity it goes great for the model part.but for the prefab part,The prefabs of my models always get ruined whenever i reimport a model in unity3D.Is there a way to make it that anytime i reimport a model into unity the prefab of the previous version of the same exact model that i reimport doesn’t get ruin each time?
When you re import, you are rewriting the data that prefab is based on. So, the prefab will change accordingly, usually get broken.
To avoid that, you either will have the final version of the model and create a prefab from it, or import models with different names (preferably to different folders to avoid confusion), or create the prefab so that model (mesh renderer) does not affect its structure.
I usually do that with versioning. I had some folders called model_a_V1, model_a_V2, model_a_V3 etc. When things are being finalized, I removed first two folders and renamed model_a_v3 to model_a_final so it gives the idea to everyone working on the project.
These are basic conventions, but if you overwrite a model, it will always affect your previous work.
