>>5817186If you mean how to make ground and stuff like that I use Paris plaster:
-CHEAP
-Can be "colored" while mixing with pigments or enamel products
-Can be applied easily (and also easy to clean)
-Can be painted after it dries with acrylics, pigments, whatever
-And of course you can "glue" stuff while it’s drying (be careful and work fast and by areas as it dries fast) or glue stuff on top
Here you have a nice and easy tutorial by mig jimenez of a general diorama
The most expensive thing he used is the terrain pads that costs like 13€ and can be used as a base or can be cut and worked on as he does. I have the "stony steppe" one and it’s really good. Following what he does in his tutorial its really simple and gives results, but you can use other products (a lot of alternatives to list here but check Forest-In-A-Pot for example for groundwork)
Dioramas are a complex subject and in a post you can’t get much, I recommend you to read some books (there are a lot of them and by really good modelers with a lot of tricks and SBS) or check youtube tutorials/builds (less quality than specialized material but easier to get).
Also I’m not a fan of posting ripped material but I can’t find this book anywhere for a reasonable price, The Diorama Perfection by Yoshioka, so I downloaded it and will re-share. It’s extremely good but in Japanese (all the text) as it covers all the aspects and the images are pretty explanatory, but a lot of info is lost in the text sadly.
