I looked back to my old geometry layout 0x18 command notes and figured out how to edit the paintings inside the castle; so I thought I would share some new notes on how the castle paintings work.

[Image: Aggk712.png?2][Image: blaToFR.png][Image: ps21iJl.png]

Setting up paintings requires at least 2 0x18 commands in the geometry layout:

[ 18 00 00 00 80 2D 5D 0C ] -- Processes Mario's position (Used for the ripple effect)
[ 18 00 XX YY 80 2D 5B 98 ] -- Renders a painting

The XX parameter tells the game which painting list to use (0 = HMC pool, 1 = Castle Paintings, 2 = TTM slide entrance), while the YY parameter tells the game which painting in that list to use.

Spoiler: Painting list
(XX == 0)
00 = Shiny black pool in HMC = [07 02 55 1C]

(XX == 1)
00 = Bob-omb's Battlefield = [07 02 36 20]
01 = Cool-cool Mountain = [07 02 36 98]
02 = Whomp's Fortress = [07 02 37 10]
03 = Jolly Roger's Bay = [07 02 37 88]
04 = Lethal Lava Land = [07 02 38 00]
05 = Shifting Sand Land = [07 02 38 78]
06 = Hazy Maze Cave (Shiny black pool) = [07 02 38 F0]
07 = Dire Dire Docks = [07 02 39 68]
08 = Wet Dry World = [07 02 39 E0]
09 = Tiny Huge Island (Tiny painting) = [07 02 3A 58]
0A = Tall Tall Mountain = [07 02 3A D0]
0B = Tick Tock Clock = [07 02 3B 48]
0C = Snowman's Land = [07 02 3B C0]
0D = Tiny Huge Island (Huge painting) = [07 02 3C 38]

(XX == 2)
00 = Painting leading to slide in TTM = [ 07 01 2F 00 ]
Each segmented address you see in the painting list points to a C structure containing information on that painting.

(u8) 0x71-0x73 - Unused bytes

** collision values are: 0x20(painting wobble left side), 0x10(painting wobble middle), 0x8(painting wobble right side), 0x4(level entrance left side), 0x02(level entrance middle), or 0x01(level entrance right side).

So, where is the data in the ROM file and in RAM?

The painting data is loaded into memory as soon as the game boots up. You can find the list pointers starting at ROM address 0xEC34C, which is loaded into RAM at 0x8033134C. You will have to look at the level script 0x17 command to find out where segment 0x07 is loaded from.

If you have any questions or additions to the topic, please leave a reply below. I'll try to update the main post as much as I can.

DOES THIS MEAN... we can stop having nonsolid boxes with a warpbox behind as paintings?

Paintings should work in custom levels just fine, though I haven't tested it out yet. 

Skelux can probably come up with a simple painting editor for a future version of the SM64 Editor. For the visual part all he would have to do is modify the painting structs and add the 0x18 commands to the geometry layout for that level. The collision for the painting is a bit more complicated as there are 6 dedicated collision ID's for each painting (The black shiny pool might be an exception), but the user could just add that in themselves.

I've spent the past few hours trying to fill out the painting struct, which is updated on the main post above. I believe that I got most of it, but it still has a few unknowns that I'll look into another day. Here are my current notes including the structure, RAM & ROM addresses, and some of the ASM functions if anyone is interested.

interesting finds, i remember years back i accidentally deleted my documents on this and never found the motivation to look into them again. If you want to find the warp ID it assigns, 8033b256 could be useful. (dont see those in the docs yet)

I've been working on decoding all the data in segment 02 (the font and HUD textures inflated from MIO0 block 0x108A40). There are some peculiar data at the end of the file starting at segmented address 0x020178C0 that didn't fit texture, F3D, or dialog patterns. I dug into it more and found the code that uses it and it is related to the castle paintings. It is the vertex and triangle data used to form the castle paintings mesh. Function at address 802D556C looks up the virtual address from 0x020178C0 and reads the vertex and triangle counts below. It then passes this data to functions 802D3EE4, 802D404C, and 802D44BC for loading.

The data takes the following format, offsets relative to segment 02 base (think this is at 0x81AA16 in extended ROM)
Code:
178C0-178C1: u16 vertex count (0x009D=157)
178C2-17C6F: i16 x, y, z vertices (157*6 bytes)
17C70-17C71: u16 triangle count (0x0108=264)
17C72-182A1: u16 3x triangle indexes (264*6 bytes)
182A2-18A0D: TODO - looks like more indexes, but higher than vertex count. maybe triangle indexes?

Something like this is relatively easy to parse into OBJ format. This is what the mesh looks like:

It looks flat, but there is a small variation in the Z axis.

I actually got the paintings to work in custom stages. (Finally!)

Multiple paintings in custom levels also work as seen in the video I created below.

HOW!?!?!??!
ik I have a lot of projects, so quit bugging me about it

Maybe someone (Maybe supermariosan100 since he's already got paintings working in custom levels) could make a patch or tweak to add paintings into custom levels, Just a suggestion
