[WIP] By the gods - God game

cybereality I think for retro graphics like that you should be able to have a few hundred characters (or more on a higher end system).

Graphical fidelity/polycount isn't the bottleneck here. One would have to take a deep dive into godot servers to do a more data oriented design thing for mass npc/crowd sim in realtime.

Now that I think about it, in AAA games with lots of characters, they usually use imposters or instancing, not hundreds of unique independently animated people.

Still though, the scene looks fairly simple so I believe it should be possible with the right settings.

Here's how my hierarchy is looking right now for my male villager, there's likely a clue somewhere that I've missed if it's possible it's down to setup more than the issue of rendering hundreds of villagers, the top most parent has been highlighted.

Hmmmm.....

I should point out actually, that I made the villager a local part of the scene while I figured everything out and got it working, I guess now is the time to start fiddling with having it as it's own instance among other things.

Lethn

No way! LOL I think it was just because I hadn't made the villager into an instanced scene, hang on, I've got to do some more testing on this now.

Lethn

Okay, it's chugging a bit at 400 villagers but that's a massive improvement already.

Lethn

I can get 30fps at 300 villagers but it just tanks after anymore than that, that's very interesting I bet it will run a lot better with multi-threading regardless if instancing does this much for performance.

Now what if you disable visibility of villagers at a certain distance from the camera or it's point of focus/view intersection with terrain?

cybereality

Interesting. That is good news. I still think the model has too many pieces. You might want to find a way to combine the clothing and accessories so it is one mesh. I think that is the main issue.

Lethn

I'll look into it, that would be extremely tricky because the idea is the villagers have their own tools and everything that they use like woodcutting and so on and I need to be able to hide/show them pretty cleanly like in RPGs for weapon equipping, this will be something else for me to poke at.

Lethn

Megalomaniak Well that would be frustrum culling wouldn't it? If I recall correctly that's even built into Godot and I just need to check out how the LOD settings work in Godot to see if tweaking those settings can help the performance there, I love how much more straightforward this stuff is to setup in Godot lol it's kind of unbelievable.

cybereality

Tools and weapons are fine, because they can be separate static objects (not part of the skin) and use a bone attachment.

In terms of the different outfits, you can do a lot with texture mapping, to have maybe only a few different meshes with a large variety of textures (as this does not cost performance).

But if each piece in the mesh is a sub mesh (with another material) this is going to cost a lot of performance.

Megalomaniak

Lethn Well that would be frustrum culling wouldn't it?

Not exactly. Frustum culling takes the view bounds or 'cone' if you will into account. Which is also why I can't guarantee that it will improve performance further, but it might be worth trying.

Interesting.

Ahhhh, now we're getting somewhere, this is so much more interesting than dealing with vector3's and rotation maths lol.
