This was super helpful. Thanks for making it concise and straightforward!
Thank you so much Andrea! This was very helpful.
Great tutorials, love the accent! Thanks man
Thank You for this Great Tutorial!!!
well done. Very good tutorial
Great. I'm interested in Gaia to UNREAL workflow... Please make more tuts on this. 🔥
Thank you, very helpful!
Grazie, molto utile e spiegato bene :)
grazie Andrea!
Di nulla !
Great tutorials, I watched almost all of them! Do you think you could make a tutorial on how to export a splat map for us Unreal Engine users? I know many people around the web ask each other how to do this, and I think the tutorial would benefit many people. In addition to the height map, a Splat map with the different slopes/fall off/ soil levels would be very beneficial for further terrain development inside Unreal 5. Thank you for your time in making these wonderful tutorials!!!
Thanks for the compliments ! Regarding the creation process of a splat map is quite straightforward:
Create a "Splat" node which is located under the "Color" category. This node has 4 inputs RGBA. Simply connect the masks you want to the various inputs. For ex. rockmap to R, slope to G and a combination of soil+flows ( combine set to Max ) to B.
After that mark for export the "Splat" node and that's it. You can always play around with the settings of the node to get the result you want.
Hi Andrea new subscriber here!, a bit late but do you have a plan of introducing a basic workaround of exporting splatmap or a flowmap and a heightmap to unreal engine and split this map into a 4 section to coordinate in x and y same with world machine where you can export it that way.
So how about export those heatmaps (like vegetation and so on) to Unreal?
You mark them for export and then use those maps as masks however I never used them in this manner and i switched to pre rendered works years ago so I can't help you in that sense
I dl'd community which said I can make 1024 hm's
I shows an error and I get no hm
I can get an hm in 5 minutes from l3dt
so I am uninstalling it.
The export process is foolish.
When exporting this as a fbx - how long time does it usually take you ranging from 1k to 8k?
Build time is based on the complexity of the terrain, if you used a lot of "LookDev" nodes ( they are heavy ), how powerful your CPU is and amount of RAM. I don't remember how long it took to build this terrain ( shape+textures ) but when i made this video i still had my old PC which had an i7 2600k with 24 gb RAM and in general it took roughly 20 mins for the 4k version and up to 3 hours for the 8k version if the terrain was very complex because i didn't have enough RAM ( very complex = a boreal forest like one of my latest videos ).
With my current workstation ( Ryzen 9 5950x with 64 gb RAM ) from 1k to 2k is practically instantaneous, for the 4k version it takes a max of 5 mins and for the 8k version a max of 30 mins for very complex terrains.
Hey Andrea Nice to meet you I am new with Gaea I use World creator 2 but i am interested in Gaea, I have a Question for you I am following you tutorial but i only see half of the terrain, why is that? maybe there is a button i can click that i dont know about.
Thank you and keep up the good work
Hi, do you see half of the terrain in Gaea viewport or when you export it shows only half of the whole terrain ?
Andrea Cantelli it in the viewport
That's strange, so basically you only see the half bottom of the terrain ? Check your graph, maybe you enabled one of the adjustments options of a node. You can see them in the bottom right corner where the node properties are.
If a node has an adjustment enabled it should have a blue dot under him.
Also check the "influence" value of the various nodes located at the same position of the adjustments, you must click on the arrow next to them. "Influence" should be set at 100 % for this tutorial.
You can also try creating a new empy scene and import your graph by going to: Gaea menu ( top left corner )---> import graph---> select the .tor file
Andrea Cantelli thank you i will try that
Hey Andrea, nice tutorial. Cheers.
I have a question that is endlessly an issue for me, but apparently only me :)
My exported disp map never looks like my mesher geo. It always appears non linear (which the output would suggest) but there is no linear output option.
I found a way to do it with the older versions (as per this quadspinner.zendesk.com/hc/en-us/community/posts/360039370473-Exporting-maps-and-gamma-correction-in-Gaea )
but cant seem to find a solution now.
Any idea? Cheers
Hi, sorry for the late reply but UA-cam automatically blocked your comment for some reason so i didn't notice it.
Regarding your question i never had any issues with the displacement, i always export using the OpenEXR 32 bit format and it works well.
You could try exporting with a different "Output Range" setting like "Normalized" maybe it help.
