Add normal maps #34901

About the PR

Bump maps by notquitehadouken for SS14.

You can PR to 25-02-05-bumps on my repo if you want to add bump map (or normal map) sprites, which will speed this up significantly because There's A Lot Of Stuff & Things. Most of them are covered by the normal generator in the engine PR, but some things might need extra spriting (like all the non-main-body species sprites) that I am too inexperienced or time constrained to do. If you do make a PR, comment a link to it here because I will not find it otherwise. I will add you to the CL authors if you do this.

How to add a bump map

Pick a sprite (e.g. protolathe)

If you're just making it shaded flatly (like tables), skip all these steps and go straight to adding it to the RSI:

Create a new image with the same dimensions as the sprite in your preferred image editor (I use paint.net because layers are easy but you do you)

Add a completely black background
- If it helps (and it will), add the regular sprite and draw over it. Remember to remove it after you're done, or else your sprite will look fungly.
Draw the bump map COMPLETELY in black and white. White is closer, black is farther.
- Bump maps are linear. Black is considered the farthest, white is the closest, and 50% is halfway between.
Follow generally the same color scheme as the rest of the bump maps I've already made. If you need a reference, use Human/parts.rsi/bump.png.
It is not recommended to use pure white for the main body of the sprite, as other parts may be further towards the camera (like the hands on the left and right sprites for people)
The bump map is masked to the sprite it's associated with, so you shouldn't add any transparency to it. For sprites typically used in parts (like the lizard tail), make sure the bump map extends slightly beyond the actual sprite if it would be necessary.
- If you have no idea what I'm talking about, take one of the lizard tail or snout sprites and overlay it with its bump map. Notice how the bump map is bigger than the actual sprite!
If your bump map is right up against the edge, note that anything beyond the bounds of the image is considered to be completely black.
- This includes boundaries between different parts of the image, like species sprites, which have 4 directions. If something was against the edge of one of those 32 x 32 blocks, then anything beyond that block would be considered completely black, even if there was actually something there in the bump map.
Put "bump" in the name of the sprite. This isn't required, it just makes it easier to sort.

Once your finish making your bump map, follow these steps to add it to the RSI:

Find the sprite you want to add a bump map to

If you just want to make it flatly shaded, add "flatNormal": true, in the state associated with the sprite
If you want to make the ENTIRE RSI flatly shaded, add that same text outside of the states (like any of the table RSIs)
Bump and normal maps take precedence over flat shading, so if you include flatNormal alongside a bump or normal map, then the flatNormal will be ignored completely.

To add a bump map, go to the state you want to add a bump map to and add "bump": followed by the name of the image in quotes, just like you would do to add a regular sprite with "name":.
To add a normal map, do the same thing, but use the key "normal" instead of the key "bump".

Add an option in settings to turn off and on normal maps (Requires Add "Custom" setting to lighting quality #35039)
Add bump maps for most things seen a lot

Need to make bump maps for (In order of priority):

Covered by autogenerated normals (Or not worth the effort):

Very very specific items
Inhands
- Too small, not worth the effort for something where my change is gonna be "Yowza! It looks like the autogenerated sprite but worse!"
Anything that's less than 5x5 pixels
- Not much detail to extrapolate depth from.
Basically anything living
- Not common enough in Regular Gameplay (e.g. any dept that isn't related to the kitchen) to warrant the difficulty. Enjoy perfectly flat cow, nerd.
Anything that's mostly flat
- Cloaks
- Beds
- Bedsheets
- IDs
- EMAG
- Boxes
- Basically all clothing
Guns
Hair
Has shader: unshaded on it
- Self explanatory

Why / Balance

Normal maps are Cool and so is lighting in general

they tell the computer what direction parts of a sprite are facing. so you could mark pixels as the front of your sprite, and if there's a light infront of the sprite, those pixels will be illuminated. however, if there's a light behind your sprite, they won't be

There's more to it than that ofc so you can read an explainer like this https://www.artstation.com/blogs/typhen/GMyG/this-is-normal-1-what-normal-maps-are-and-how-they-work

TLDR tho it means certain materials can get really sloggers lighting effects... especially if we get specular maps some time :godo:

gonna be ready in like 2 months fr fr

Also I think in order for your tests to pass you'll have to add schema information in rsi-schema.json.

ArtisticRoomba · 2025-02-20T00:40:31Z

The RSI validator, which checks meta.jsons, uses rsi-schema.json as a base to check against. That test is crying, and you've added new metadata information that isn't defined as standard in the schema, so when the test goes to check your new metadata files against the rsi-schema.json file to make sure everything is correct, it cries because it sees something it doesn't expect. That's my guess though.

validate-rsis.py is crying because it looks for all the pngs in the state objects and because it can't find the bump maps (it only checks the "name" field) it screams because they're defined In A Different Way. also it's in the engine so i can't do anything about it (in this pr)

ArtisticRoomba · 2025-02-20T00:48:09Z

Ah, well, sounds like you need to make another engine PR (godo).
