Hi!
I’m a pretty creative person and can create a lot of concepts myself, but even I get stuck sometimes!
How to detail and add layout variation
Of course it depends entirely on the scene you’re trying to make, and what style it is. I generally build in a detailed medieval style, but a lot of this can be applicable for other styles, too. For example,
In this nature scene, I used slate parts with a stone wall texture to divide it into two sections, added a small amount of growth in the bottom layer to add some dirt, and then grass terrain, stone terrain with some mesh rocks I made. I find that even if you just have a simple textured part between layers it can add a lot more detail. For the layout, don’t underestimate colour! Just changing the colours of the flowers and rotating it at different angles made it look more aesthetically pleasing.
One method I use for detail a lot is changing the colour or rotation/position of one part. For example,
These are all the same spike, but they’re at different angles, sizes and positions to create a more detailed appearance and interesting layout.
The rocks are the same part, too, but I stacked two at different angles and had the other one much smaller and rotated to create a detailed display of nature.
In terms of buildings, I love to use a mixture of textures on normal parts and blender for more specific shapes. For example, for this house, I used textures on the roof tiles and walls to give it more detail, and mesh parts to make the edges of the stone base and stone supports.
Terrain
Terrain can seem tricky at first but it’s really easy when you’re used to it.
I’d really recommend generating some terrain and then messing around with the terrain edit tools to get more used to it. I mainly use “add”, “grow”, “erode” and “paint” to edit terrain.
Let’s say you generate some terrain and want to create some flat land or cover up some water, gaps, etc. Use the “add” tool and make sure that “snap to grid” is turned on and “ignore water” is turned off if you’re doing it over water. Make sure you have a bird’s eye view above and paint, like this. Adjust the scale if you need it to be higher.
Let’s say you want to make a rock formation, like I showed earlier. You’ll need the “grow tool”, and make sure the scale and strength are low. Press down in an area and move around only slightly.
Then you can just rest some plants against it to create a nature scene.
If you want to adjust the terrain to make it slope more, gently use the erode tool with size and strength very low, and gently just run along the area, creating this kind of effect.
Concept Creation
This part is pretty easy. If I ever get stuck with trying to find a concept, I just go to deviant art or google images and google certain things that I’m trying to make. I spam a folder I have for reference photos of the certain thing I’m trying to make and pick out the particular parts I really like, and note which parts I don’t like. For example,
I’ll also look for similar concepts with the things I like, or try and “replace” the stuff I don’t like, like the ugly roof tiles, with ones I much prefer. I do this until I have a list in my head of things I want to make i.e, detailed wood door, the wood pannelling detailing, windows in the roof, specific roof tiles, etc etc. Then I experiment with different concepts until I find “the one”, so to speak.
And then I made a lot of similar houses in that style.
This may seem a little weird, but sometimes I also use sandbox games like sims or minecraft to make a concept that I’m struggling with before I build it.
Hope this helps. Good luck!
