Hi I am wondering if someone could help me with whats going on below. The model on the right is the model from Zbrush I exported. I started with a shape in Maya goZ it to Zbrush, sculpted a high poly, then duplicated, and projected etc. I exported both Hi and low from Zbrush to bake my normal in Substance and texture. I then exported it and imported to UE. After importing it looks all faceted. I'm wondering how come?

On the left is the same lowpoly from zbrush just GoZ'd back to maya and auto UV'd and exported. I just put the other material on to check the model and its all smooth with out and facets showing. Can anyone explain what is happening. Thanks for your time. Have a great day!th

    I believe this is something to do with normals, like almost every irritating issue in game art!

    I think... if you import your model into maya and select all the edges and set them to smooth instead of hard and then export, it should fix your problem. (Mesh display - soften edge).

    Zbrush does not read or write vertex normals.

    if you want something out of zbrush to have soft normals you need to use the FBX pluggin and make sure to select the soft normal box. I would recommend passing the mesh trough maya before going UE4 tho, as you will want to name your materials and UVs and those tasks cant be done on zbrush.
