So you do need to highlight all the edges? Ok. All edges? Which includes the spherical part or just the straight lines going from the origin outwards like a pyramid?
The straight lines will be enoughā¦generally speaking lines on all cut edges will be perfectā¦
@Everynone Do you ahve any idea what is happening here ? Trying to visualize but not getting itā¦ 
Thanks @L1z4rD89 But why are we doing it 4 times. Is it for up and down for 2 half spheres ? and when the (-1,0,0) vector rotated by vertical angle/2, does the (x,y,z) co-ordinates change ?
4 times because:
Up and Down for 2 half spheres => 4 times
1,0,0 rotated by 10Ā° (around Y axis) => 0.98481, 0, 0.17365
1,0,0 rotated by 45Ā° (around Y axis) => 0.70711, 0, 0.70711
1,0,0 rotated by 90Ā° (around Y axis) => 0,0,1
So for horizontal cutting, we use only one plane to cut on halfā¦thats why we have only two horizontal slicingā¦? acn you also able to share what is the logic after slicing in horizontal and vertical ?
Grabbing the geometry of the sliced procedural mesh and creating a new one ?
I added some small explanations but to really see what is happening you should disconnect some nodes and watch what happens with the mesh.
I also added a small sphere so you can see which POINT I want to calculate. This point is a direction vector like the rotated -1,0,0. If you rotate this direction vector by 90Ā° you get the orthogonal counterpart. And this counterpart, the direction vector which is rotated by 90Ā° is the face normal for the SliceNode.

Thanksā¦i will doā¦i think the outlines have problem when the scale chnagesā¦i am workign with a sphere of 1000 cm and when i set 1000 in scale, the outline is so thin and canāt able to see the linesā¦
Inside the material folder there is a material called M_HemispherePostProcess. Open it and in the bottom left corner is a parameter called Thickness. Use a value greater than 1.
The sphere has a radius of 50cm. So if you want to use a sphere with a radius of 1000cm you need a scale of 20. A scale of 1000 gives you a sphere with 50000cm radius => 500m.
YEs i done that previously but still canāt able to get a lineā¦thanks for your timeā¦
It works till 180 deg of horizontal angle but more than that it wonātā¦so i thin i have to attach the Use CustomDepth for edge detection (black lines) for other branch of conditional statement alsoā¦
Yes, could be possible that I forgot that. You have to use it for TRUE And FALSE or place it before the BRANCH
Since the M_Hemispherepostprocess is an instance of M_Hemisphere, any change in M_Hemisphere should reflect in M_Hemispherepostprocess, right ? I changed the blend mode to translucent and the cut section become transparentā¦but then the line goneā¦is it related to post-processing?
Erm, the PostProcess material should be separate from the other material. M_Hemisphere is a material for the mesh, M_HemispherePostProcess is used inside the PostProcessVolume. What did you change, what is the result: Can you show a picture?
So what if we can be able to change the opacity of the M_Hemisphere ? From what i understood the borders come on post processing, right ? or the whole sphere is covered with the post processing material ?
Also i guess the borders does not work for me since it also affecting the floor and the car as well.
