Diablo Trees In Game.

I'm going to leave trees and move on with some other stuff for a while.
I think the trees look pretty good and performance is much better than when i was using individual tree sprites.

I'm still conflicted about how to handle alpha in the game. Here's a shot of the trees with clip alpha:

Clip alpha is basically either/or alpha. Either it's 100% transparent or it's not. It's very fast to render, but it gives pretty horrible edges.

Another option is to use alpha sort. This is similar to the alpha blend I use for the infantry sprites (grayscale alpha) but it works to sort the individual polys of the mesh to make sure they get rendered in the right order.

Performance is slightly slower than with clip alpha. But the end result looks much, much nicer. Again this may be something I make a part of the graphics settings, as it would be possible to load different trees from file, some with alpha sort and others with alpha clip and lower resolution.

Automating Level imports from Blender to Godot

Recently I've been making some levels in Blender an importing them into Godot. There are only about 7 or 8 shaders for each level, not counting dynamic objects which will be added later. But to improve rendering performance, it can be a good idea to split the meshes up into sections. At that point you might be faced with a list like this: Or it might be even more chaotic, if you didn't use simple names for the objects in your level. So it can take a long time to sort out all the meshes, make them unique and add textures and so on. Blender imports with simple Blender textures, or with placeholder materials. This is sometimes OK, but if your Godot shaders are very different to those used by Blender, it means applying new materials to every mesh object in the level when you import the scene. I found that during the design process, I was importing and readying a level several times before I was happy with the final layout. So at first I was wasting a lot of time. In Blender, I us

Upstairs / Downstairs.

I've decided to make my prefabs multilevel. Later this should allow me to add pit traps and other great stuff. It also makes it easier to line up stairs so that you can exit them on the same co-ordinates where you entered them. The prefab editor is pretty much finished, it just needs some code for loading up prefabs from a saved dictionary, so that they can be checked or edited. The entries will need to be forwards compatible, so I'll be loading each tile and then translating the indexes to a new array, that way if I add extra indexes or extra info (like traps or puzzles) I'll be able to update existing prefabs to work with the new standard.

Advice needed on tilesets...

I need some advice on which is the best way to handle building the dungeon. Right now I'm using prefabs for my dungeon, they have a north south east and west section for each "room": The basic tileset. This has several advantages, and also several disadvantages. Firstly I can have curved rooms, I can have tunnels and other interesting shapes. The tilesets can look quite nice with a little work. On the other hand I can't easily get the navigation data before building the map and once the map has been built I can't make changes to the layout, like having active pit traps or believable secret doors. Although the rooms are interesting, they are quite repetitive, and it takes a lot of effort to make even a few different variations. Also rooms are constrained to one size. A newer version of the tileset with a lot of variant parts for making more interesting rooms. To create a tile set is a real headache too. Planning how to lay out the UVs, trying to cra
