Blender Secrets - Blender GIS (Extra Bonus Tutorial)

hey guys it's jan and i wanted to go a little bit further in depth on blender gis which is something that i made a short one minute video about a few days weeks ago and uh there seemed to be some confusion about whether i'd made the opening render of the [Music] matterhorn mountain with blender gis and yes i definitely did uh i just probably went a little bit too fast in the video so i will show you now step by step how to make such a nice render and uh if you're interested in this kind of stuff and you want to know more in depth with a real video course how to make environments blender i couldn't recommend anything that's better than the course martin collector made over on cg boost he really spent months figuring out every single variable button you can press in blender just to make the most awesome nature renders so i would definitely check that out you can find the link in the description alrighty so here we are in blender and i've already put a screenshot from google maps of the matterhorn exact location because otherwise i would never find it and here we're going to do this menu to load the base map which basically just loads the whole earth and then you can zoom in to where you want so obviously the matterhorn is in the blurry place of europe in fact it's in switzerland i can already see it it's right there it looks like we are targeting you switzerland for destruction or something from space there it is now you can lock by pressing l you can lock the region that you've selected like this region i don't want to zoom in anymore but i do want to increase the resolution so i press l to lock and then i scroll up on the mouse wheel and it will still increase the resolution but it takes a long time i've sped it up here it takes forever to download it can take like 20 minutes or something and then you get this shiny plane and you can download the height map as well which also takes a minute or five or ten and you get this shiny blob of relief i really recommend you embed the texture in the file and save it because otherwise if it crashes you lose the resolution of the terrain you lose the height map i mean here to get the most out of it i simplified it in edit mode you really have to do that otherwise you don't have enough detail reduce the specularity and increase the roughness of that map otherwise it would look strangely shiny and i can uh tell you from experience that switzerland is not shiny like that so here i'm adding a hdri with a gear for add-on which is the probably the best add-on i've ever bought and the blender is already unhappy because it's so many subdivisions so i've turned on simplify and i'm adding a camera but the camera doesn't see anything because it's all too big so i have to add i have to increase the clipping and otherwise it's it's a massive massive mesh basically so i've locked the camera to view so i can move around and find a nice shot here later i will increase the the height of these mountains a bit in the modifier the displacement modifier because it's a bit too boring now so now i'm just trying to search which one is the matterhorn again and finding a nice angle with the camera and changing the length of the lens a bit to make it a bit more dramatic 30 millimeter it's a good good camera lens length for this kind of stuff so i just added a an empty although you can see it because the overlays were turned off and the empty will be the target for the depth of field of the camera which is always nice but in this case the mesh is just so gigantic that you can't really see the depth of field so i was trying to scale it down and see if i could get a bit more blurriness here you go and experimenting a bit more with the hdris from there mostly from hdri haven but you can just automatically download them all with the geffer add-on it's really awesome and this is my book i was just sometimes i read my own book you know i was just checking which picture that i used for the background that's this one from textures.com i downloaded it as an image on plane with the images as plains add-on uh set to emit of course and then just kind of line it up with the camera if i were really smart which unfortunately i'm not i would have parented it to the camera but i didn't so later i have to move it again when i move the camera here i'm rotating this hdri a bit and setting up some kind of camera move you can actually scale keyframes in the timeline which can be very handy but blender kept crashing when i try to render it so here is a quick tip you can increase the scale of your camera that way you can get kind of the camera fulcrum or the area which is inside the camera view and then just select everything else and just delete it that way you massively reduce the amount of memory you have to use and then you can actually render it so here you go this is the rendered shot i added a little bit of rotation to the camera movement so yeah good luck with the blender js it's a lot of fun you need some patience but it's worth it you
