Screenshots below. Map preview does not show resources or biters if RSO is enabled. Toggled RSO off and selected the same settings for map generation and the preview showed resources and biters.

RSO is the only mod I used for this test.

With RSO:


Without RSO (completely vanilla):

Well the RSO script won't run outside of the game,
And we didn't really intend it to

So this isn't a bug, and/or we won't fix it

That's disappointing. This means the feature is completely unusable if you prefer RSO resource generation

Yep.

So... how does the game know not to render the default resource locations if it's not running the RSO script?

It changes the autoplace or something

So RSO's data stage stuff is applied, but not control stage stuff?

Yes

This prompts me to go confirm that my World Mirror mod is also not accurately represented in the map preview.

I am sad that chunk generation mod code isn't run as part of the preview

It's a preview. Why would runtime lua scripting that is associated with a specific game be executed in a preview? It doesn't even run the full normal game code.

All the same reasons the preview exists in the first place. Players want to see where water, desert, resources biters, etc are, and reject maps more quickly than doing repeated Restarts.

Because the runtime lua scripting affects the map, and a preview of that map is not just inaccurate but useless without it.

I understand if you don't want to do it for any reason. It's not your job to make modders' lives better, it's to make the best vanilla game you can. But you did ask for a reason.

In this case, the modder/mod should leverage the existing (and new) features we provide to fulfil the goal of the mod.

The mod wants to overhaul the map generation, but does so by completely ignoring all the in-game functionality for map generation, and doing its own thing with Lua scripting,
There are many many ways, even moreso in 0.16 (Programmable noise) to accomplish the things RSO sets out to do

In this case if you want this problem to be fixed (Preview not working with RSO), then contact the mod author and ask them to implement their mod in a way that is compatible with the map preview feature.

There is no way to recreate what RSO does with anything that base game offers. Thats why it's completely different and it won't appear on map previews. It might not be 100% user friendly but preview simply won't work with RSO.

With RSO i don't need a preview because i know it works.

RSO resource generation isn't random noise. That's the whole point and is what makes it so good

Yeah, you get guaranteed resources in the starting area. There is still some variation with it, but it's almost always something you can work with

Agreed, it doesn't matter much that you can't see a preview with RSO, because it works so well. At the moment it's not worth playing Factorio without RSO.

While true, it'd be nice to get quick feedback on changes to settings to know that your particular settings work for the setup you're trying to generate.

I would like to see RSO generated resources show up in the map preview. Its nice to see how big the resource piles are for each map and being able to fine tune it without having to deal with the long restart times.

@Klonan/Rsed:
How feasible would something like a "full preview" button be? I.e. you press the button and the game internally generates an actual map instance where mod code can run, then generate a pictures of that. It'd probably take 5 mins to generate, but some people might still prefer that to nothing.
