How do I enable the roughness of the models in the material settings? In Blender, you can enable bumps and valleys, how to achieve the same result in UE4?
With Physically-Based Rendering (PBR), Roughness is how polished something is. 0 roughness is reflective, 1 is matte.
You must be talking about normal maps.
You need a normal map, as stated above:
And the intro to materials:
You will need to import a special Map associated with this mesh and plug it in here:
It emulates light hitting irregular / uneven surfaces making the impression that the mesh is more detailed and complex.
That is, in a blender you need to create a normal map of this texture and then import it into ue4? And connect to normal. It is a pity that there is simply no checkbox in an unreal engine like in a blender. Why is texcoord there? I’m thinking of watching a video on how to create a normal map in blender. Thank you.
Will there be outline of the model then?
This greatly improves any model, I think you will agree with me! I am in favor of all models with normal maps. All my models will have normal maps. It’s amazing how these two automata differ, and I have been doing modeling for a long time, but I did not know about such a thing.
Can I just bake this thing into a texture in a blender?
Normal maps have been in use for a long time and they will be in use for some time to come. You will need to study them, especially if you’re a modeller:
The answers to your questions are readily available on YT:
And if this video does not work for you / you do not like it for some reason, there’s always another video, another blog, another tutorial and another forum thread about it.
it takes a very long time for me to bake 4096
And if I bake on the main texture and just overlay it on the model, me won’t need a normal map?
52% Is it normal that it takes so long to bake? CPU 97%. Complete 90%
In general, nothing worked for me
