Ok so the region editors generator isn't working for me, I'm testing it on a simple flat land with just a land texture I put down, now I'm in the Region Editor window, under the "Objects" tab I simply dragged in 3 different trees & 2 bushes, I haven't changed any settings apart from checking the "Is tree" box for the trees, I click Generate now for the 2x2 cells that are selected, it loads for a second then the finish box comes up saying Objects not generated: Due to bounds: 1688, I tried changing density but nothing changed seeing as 1688 seems way too much for 4 cells, then I changed the radius, then it said Due to bounds: 32

Anyone have experience with this?

Try making the region bigger.

Tried a 3x5 region & it still didn't work, well 13 objects did. (Objects generated: 13, Not Generated: Due to Bounds: 436)

Edit: the bushes seem to be working now but not the trees, guessing it has something to do with the height.

I don't know, it works fine for me. Compare your settings to mine:

Also, if you're generating a lot of objects, you should avoid just using several "top level" objects and instead make them children of each other with a small amount of clustering.
Generating them exactly like I did in the screenshot causes a lot of trees to be placed in a straight line with even spacing.

What I'm really looking for help with is how to draw regions in the correct places on a very large map (256x256 cells). It seems like my only option is to draw a grid over the heightmap in photoshop, and then draw polygons where I want the regions, and then write down every corner of every one, and then draw regions in the same places in the creation kit. A really annoying process that seems like it should be easier.

Something else that would be nice would be a way to "brush" many objects on the terrain at once, as you can do with cryengine. Region generation takes ages, so that would probably save time, even for a huge world.

Yeah my settings are the same, I don't change anything just drag the items in.

This is what I get most of the time: http://i49.tinypic.com/6r4zth.jpg

Tinkering with the settings sometimes some objects will pop through, maybe it's just buggy as hell, even on yours 9000 of them weren't generated due to bounds. And i agree with the painting on thing was actually thinking of that a while ago

Yeah, I'm pretty sure that Bethesda did not use it. Manual terrain texture/color painting works pretty good if you set ugridstoload to something like 20, but I have no idea how they placed the vegetation/rocks. I'm pretty sure they didn't use the region generator, because the placement of rocks and trees is very deliberate in most places, none of their regions have objects enabled, and aside from apparently being buggy as hell, it always takes a very long time. A 10x10 cell region with just a few terrain textures only takes 10-20 seconds, but that time becomes like 10 times as long if there are several objects, and generating objects for thousands of cells would take many hours.

At the same time, I can't imagine them placing every single tree and rock in the game world by dragging it into place either, so I wonder if they generate the objects with a different program/feature we don't have, or if there's a better way to do it that we're missing.

One thing I notice in your screenshot is: It looks like you clicked "generate now", but I right-clicked on the region area and selected "generate objects for area 1" instead. I don't know why that would make a difference, but you can try it.

I believe Todd said they hand placed every single object, also i think it's just minor bugs as it was useable on fallout 3 & some people have used it in their custom skyrim maps.

Just need to figure out why it's not getting generated "due to bounds".

Bump

The only thing that springs to mind is make sure your land height is above zero. Your screenshot shows you have the minimum height set to zero. If your land is lower, it's considered out of bounds.

It that case, you could either raise the land, or change the minimum height setting to -10,000

Another thing I noticed, if you create a new region and try to add objects straight away, you sometimes get the same problem. What I do is create the new region and allow objects. Save the esp and close the CK. Open the CK with the esp again and generate objects. Always seems to work if the region is pre-made, for some reason.

I've tinkered with the land height, same results, although like you said the first time you do it after opening the kit, it sort of half works, half the objects come through & half don't, it seems smaller objects seem to work better, All the bushes come through, sometimes the smaller trees & so on.

Bump

Sorry, I should have mentioned this in the other post.

If you're only generating trees, un-tick the 'Is a Tree' box and take 150 - 250 off the 'Radius' that the CK allocates. If the CK puts a value of 400, change it 200 and see if it works (you can try different radius values).

[Edit]
If it doesn't work correctly, click obliterate now, even though nothing has been generated. Don't just change the value and try to generate again.

Yeah i've tried changing the radius & the is tree box, would give it another shot but the creation kit seems to be crashing every 30 seconds today

Here, I uploaded my ESP that I used to test the region generator:

The worldspace is called regiontest, so you can try making a new region in there and copying the settings from my post. It should work, and then you can compare what's different about your worldspace.

The generator is incredibly touchy and hard to make work well. By hard I just mean it's complex and takes a lot of practice.

The generator isn't making tree's because there isn't room for them. Uncheck IsTree (Designed to prevent the branches from clipping, but Skyrim's trees are so narrow this isn't needed) and lower the radius of absolutely everything you put into the generator. That is, assuming you want a dense forest.

I'll be doing a tutorial on the region generator at some point, as it's very tricky to learn, but incredibly powerful once you learn it.

I tried lowering/highering the radius, fiddled with every setting but yeah it's mixed results, it's not because there's no room, I got it down to 39 objects in a 3x3+ region yet it still failed due to bounds

A tutorial on it would be great tbh as it's make or break for me.
