Hi Mihai.s
I watched the video and you are to be congratulated on finding a way of reducing the polygons, through what is a very convoluted and over complex procedure.
Considering the terrain creation is a small part of the video up (to around 2 mins 50) what has to be done after really shouldn’t be necessary to that level of complexity, adjustment and general faffery.
I can create a large area terrain in sketchup simply, without having to do the multiple areas connected ( i.e importing context multiple times) it just ends up with way too much content.
If they can simply make the definition of content more definable for texture and polygons it would be great. I.e have a wider range between high and low or even to be able to set the number of polygons and perhaps textures or even a way after the terrain has been created to lower the content by merging.
I noticed you used a merge textures option (under entity info) that seemed to just merge all into one, wouldn’t it be good if you could merge say 132 patterns into 40 etc. one would be too crude.
Is there a way of just taking a created terrain (i.e. the one I did was 26km x 8km in one hit, but it contained 132 textures and 3.3 million polygons) and reducing it simply?

Method below are my notes on how create a large area terrain.
Terrain creation, using Sketchup Pro 2025. Last updated April 5th 2025.
Open Sketchup 2025
Click on Simple (Meters)
Under FILE select ADD LOCATION
A page appears. In the top left area on the page that appears, type in the area location and Search)
Note/ Get an accurate name and place as Sketchup is not good at finding some places and is easily confused.
Note the Elevation and True North offset (Its always not 0, so change to 0.)
A small box (lower left_ shows height above ground)
Drag the blue position tear drop shape to the centre of the area you want
