Landscape resolution problem: big triangles and poor details

[m.orlandi]

Hi,
I’m working on an outdoor countryside landscape; I have a big terrain in which I have to draw some water canals.
The problem is taht my landscape is compsed by triangles taht are too big to let me achieve the resolution I need to draw the canals. The resut is a pixellated effect on my terrain

Here the specs of my terrain (with values suggested in the UE4 guide):

How can I set a higher-detailed surface? Do I ahave to increase section size, sections per component, number of components or overall resolution?

Thanks in advance,
marco

p.s.:
My pc has 8core CPU, 16 Gb ram and Gpu with 4 gb ddr5 dedicated, so I should be able to handle quite hires terrain…

In your terrain Material/Shader, Set the Main nodes tessellation to PN triangles. Create a Scalar Parameter by holding “S” and clicking inside the material graph. I wouldn’t set the Scalar Parameter value larger than 0.4, but this part is really up to you. Connect the Scalar parameter to the main node where it says, “Tessellation Multiplier”. Good Luck

just scale down the whole landscape. there are parameters to enter for x,y and z axis of the landscape.

Create a new landscape based on these values.
