In the Makie v0.10.0, plotting 3D mesh is not as good as before. Here is minimal working example using Makie v0.10.0,

```julia
shell> wget https://github.com/libigl/libigl-tutorial-data/raw/master/bumpy-cube.obj

using Makie, FileIO

shape = load("bumpy-cube.obj")
im1 = mesh(shape,color=:red,shading=true)

```

However when I use Makie v0.9.6, the result is:

What parameter in Makie v0.10.0 I need to tweak to make nice 3d mesh plot?

That happens, because MeshIO doesn’t calculate normals by default anymore, if they’re missing in the obj, and in Makie, I haven’t calculated the normals explicitely when shading is on.  
I pushed a fix to master… Note, that master is not super stable at the moment, but hopefully, we’ll get tests back in shape and can tag a stable version soon!  
You’ll need:

```nohighlight
]add GLMakie#master AbstractPlotting#master

```

Btw, if you don’t want to checkout master, you can also do this, with the newest tagged version of GeometryBasics:

```julia
mesh(normal_mesh(shape) ,color=:red,shading=true)

```

You can also tweak the lighting qualities in the latest AbstractPlotting and GLMakie. See [the docs](http://makie.juliaplots.org/dev/lighting.html) for more details.

```julia
using Makie, FileIO
meshfile = Base.download("https://github.com/libigl/libigl-tutorial-data/raw/master/bumpy-cube.obj")
shape = FileIO.load(FileIO.File{FileIO.format"OBJ"}(meshfile))

# we will manipulate shininess here
shiny_node = Observable(1f0)
im1 = mesh(shape; color = :red, shininess = shiny_node)

# we give the mesh scene a title to see what the shininess is
scene = title(im1, @lift "Shininess\n" * string(round($shiny_node; sigdigits = 4)))

# now record
record(scene, "shininess.mp4", exp.(LinRange(0, 11.5, 300)); framerate = 30) do i
    shiny_node[] = i
end

```

Thank you, the GeometryBasics way is better in my case

@sdanisch - has this change been released in the latest tagged version of Makie?

Actually, using WGLMakie, I’m still seeing this issue, even on master, whether or not I use the `normal_mesh` function.

```julia
[276b4fcb] WGLMakie v0.2.9 `https://github.com/JuliaPlots/WGLMakie.jl.git#master`
[537997a7] AbstractPlotting v0.12.18

```

Although it seems that `WGLMakie` pins `AbstractPlotting` to v0.13.6, so I can’t use `AbstractPlotting#master` - not sure if this is related.

```julia
pkg> add AbstractPlotting#master
