hi,
I’m very new to blender. I just created this map where I used Cycles because I like the way it rendered it on the viewport, but when trying to render an image using the camera view it looks completely different, almost as if the 3D look went away.
(I’m showing only one image because the website only allows me to embed 1)
hi yeshco,
can you provide your blender file so we can check it out? Just upload to any cloud service and paste the link here.
thank you!
in your subdivision modifier of your plane, you have set the viewport resolution to 6, but the render resolution to 2. Change it to 6.
Oh, perfect, thanks a lot!
That solved it 
Can I ask another small question, I still see like small tile geometries in some places do you know how I can reduce that ?
i am not sure what you mean…can you upload a picture with a circle/arrow to show me what you mean?
try adding another subdivision modifier - try with 2 and slowly increase - sometimes you computer might burn after… 
If you want to render this kind of highly detailed displacement, try enabling adaptive subdivision, it’s designed for it and can get extremely fine detail at lower cost than just increasing the levels.
It will subdivide polygons based on their screen size in pixels, so closer faces get more subdivisions and farther faces get less. The default size is 1, which means each polygon will be roughly 1 pixel wide in the render, and that is fine enough that you could set the material to “displacement only” and get good results. You could also use “displacement and bump” and set the adaptive size to 3 or 4 for a cheaper alternative.
By default, the viewport will show a lower quality level than the final render. You can change that in the main render settings, in the subdivision section.
Your plane is probably shaded flat. You won’t see the difference on the flat plane, but you will after the surface is displaced.
