PIECE-BY-PIECE PACKS - RollerCoaster Tycoon World

PIECE-BY-PIECE PACKS
SPECIFICATIONS FOR UGC
LET’S GET CREATIVE !
In RollerCoaster Tycoon World,
Piece-by-Piece buildings are
created by assembling preset,
tilable combinations of pieces.
The best part? You can even
create some new pieces
yourself, thanks to our
RCTW UGC Plugin !
One of the Premade buildings of RCTW
was made with the Modern Pack of pieces.
CREATING A PACK OF PIECES
STEP 1 – GET UNITY
1.
Download and install Unity 5.3.5p7 from the official
Unity page.
https://unity3d.com/unity/qa/patchreleases/5.3.5p7
Choose Unity Editor Download Assistant.
2.
Launch Unity, and create a new Project. Give it a
proper name like “MyFirstRCTWPack” and choose a
good location to save it to. You can leave the “3D”
option selected.
3.
Click on “Create project”.
STEP 2 – GET THE PLUGIN
1.
The RCTW Plugin should already be downloaded via Steam.
To find it, go to the following folder:
C:\Program Files (x86)\Steam\steamapps
\common\RollerCoaster Tycoon World
\RollerCoaster Tycoon World_Data
\UGCPlugin\RCTWContentPlugin.unitypackage
2.
Open the file RCTWContentPlugin.unitypackage.
3.
You should see the import window in Unity, click Import.
4.
You are now ready to start creating Packs of pieces!
CREATING YOUR FIRST PIECE
STEP 3 – CHOOSE THE UGC TYPE
1.
Open the Plugin window by clicking in the menu bar on
RCTW > Open.
2.
In the new window click on “Create New …” and give a
name to your new Pack like “My First Pack Version 1”.
3.
Enable the checkbox “Piece by Piece Pack”
4.
Choose the theme for your Pack, and add a nice
description.
5.
Click on “Piece by Piece Wall” to create your first piece!
STEP 4 – CREATE THE PIECE
1.
In the new window, give it a name and drag the FBX of a
4x4 wall into the model slot. Here we used
“PxP_GEN_Wall_4x4_03.FBX” that you can find in the
templates folder, under FBXs.
2.
Click “Create”.
3.
You should now see a piece and a human for scale
reference like in the bottom screenshot. Move the
human where you like to help you verify your scale.
STEP 5 – VERIFY THE OPTIONS
1.
Select the prefab that was created for you and placed in the
scene, and look at the Inspector.
2.
Enter a good name and description. Make sure those are
relevant, as this text is used by the Keyword Search
functionality in the Piece-by-Piece Builder. A good convention is
to use the following format:
•
Name: “Beam Wall”
•
Description: “4x4. A red steel beam wall. Modern
Pack, Generic themed.”
3.
Checkboxes are already setup by default for you. Here is how
they work:
•
Edge Snapping is for Walls: snap to inside edges of the
current 4x4 cell.
•
Intersection Snapping is for Extras: snap to the
intersections of the 4x4 Grid.
•
Floor Merging is for Walls and some Extras: this allows
some selected pieces to “sink” into a floor tile if there
is one at its feet.
4.
Choose a placement audio that corresponds to the physical
aspect of your piece.
5.
Cost and resell values should be the same. A good price for one
piece is between 1 and 10. Prices can vary based on the size
and importance of the piece.
6.
Choose an excitement value around 0.1. Excitement can vary
based on the size and importance of the piece.
7.
Choose a Theme and a Theme Value around 0.5.
8.
After doing modifications on one of the prefabs in the
Hierarchy, always make sure to click on “Apply” then in the
menu bar File > Save Project.
STEP 6 – VERIFY THE COLLIDER
The colliders on the piece must respect specific rules:
1.
If you are creating a Wall, Roof or Tile, the collider
dimensions must use the dimensions specified in
the table at the end of this document called
“Pieces Dimensions Specs”.
2.
The bottom face of the collider should start at the
pivot Y position, i.e. bottom at 0.
3.
Multiple colliders are supported for Walls, Roofs,
Extras, Deco & Lights.
•
They must be on the parent GameObject.
•
One of the colliders MUST have its
bottom face at Y = 0.
•
For Walls and Roofs the multiple colliders
should still fit within the dimensions
specified in the table at the end of this
document called “Pieces Dimensions
Specs”.
4.
You can find more information for each type of
piece and how to setup their collider(s) in the
section called “Piece Specifications Per Type”.
5.
After doing modifications on one of the prefabs
in the Hierarchy, always make sure to click on
“Apply” then in the menu bar File > Save Project.
STEP 7 – VERIFY THE MATERIAL
1.
In the Hierarchy, select the mesh inside your prefab and look at
the Inspector.
2.
The mesh should already have a material. You should either
choose a material you already created (like “PxP_GEN_Bridge_01”
in this example) or modify this existing material to use one of 4
Nvizzio shaders provided in the Plugin.
3.
Here are the guidelines for the shaders:
•
NvizzioStandard_PBP is for any piece with no emissive,
like our wall here.
•
NvizzioStandard_PBP_Emissive is for any piece with
emissive, such as the Sci-Fi walls with a glowing part.
•
NvizzioStandard_PBP_AT is for any piece with cutout
transparency, such as the Mayan plants.
•
NvizzioStandard_PBP_AlphaBlend is for any piece with
blended transparency, such as the flat roof with
transparent windows in the Modern Pack.
•
S/O/E/G are four channels in one texture that
correspond to your Specular / Occlusion / Emissive /
Glossiness.
4.
You can find more information on how to setup your textures to
be compatible with the Colors tab at the end of this document in
the section called “Textures Specifications for Colors Tab”.
STEP 8 – VERIFY THE CAMERA
1.
Notice that in the Hierarchy a camera has
been created with the same name as your FBX
and your new prefab:
“Camera_PxP_GEN_Wall_4x4_03”.
2.
This camera will be used to take a screenshot
of your piece when finalizing the Pack, so
make sure to place it so that it’s looking at the
piece in a nice way.
3.
You can also adjust the lighting of the scene,
even replace the grass to something else if
you prefer.
Note: a general screenshot will also be taken for
the image of your Pack by the camera named
“Main Camera”.
STEP 9 – REPEAT
1.
You want to add more pieces to this Pack? You can do so!
Open again the Plugin window by clicking in the menu bar
on RCTW > Open.
2.
Without changing any options, click on the type of piece
you would like to add to your Pack.
3.
Repeat Steps 4 to 8 until you have all the pieces you want
in this Pack!
STEP 10 – BUILD THE PACK
1.
All the pieces are ready? Then open again the Plugin
window by clicking in the menu bar on RCTW > Open.
2.
Click on “Build My First Pack Version 1”.
3.
Click on “Include Previews in Pack”.
4.
You should now see some information below that tells
you if there were any problems generating the Pack,
like the orange warning here about an incorrect
collider size.
If everything is OK, it’s time to jump into the game!
FINAL STEP – ENABLE !
1.
Launch RCTW and open the
Social Hub.
2.
Click on the Packs tab, and
select the “My Local Content”
category.
3.
Click on your new Pack, and
select “Enable”.
4.
If you think your new Pack is
looking good don’t forget to
share it with the community !
Note: if you are overwriting an
existing Pack, you don’t have to quit
the game. Simply open the Social
Hub again, with “My Local Content”
selected in the Packs tab, select
your Pack, click “Disable” then
“Enable” again. You should now be
able to place new pieces that use
your updated Pack.

TEXTURES SPECIFICATIONS FOR COLORS TAB
TEXTURES SPECIFICATIONS FOR COLORS TAB
To be compatible with the Colors tab:
•
•
•
•
•
Your Albedo texture must be mostly white/grey, and most of its
color should come from the “Tint Color 1” value in the shader,
which is red here. This value will be changed by players when
using the Colors tab.
If you’re using NvizzioStandard_PBP_Emissive, “Emission Color”
is used instead of “Tint Color 1”. The tint chosen by the player in
the Colors tab will be applied only on the Emissive part.
If only a portion of the piece should be color tinted, your alpha in
the Albedo texture should be using black and white: the piece will
be color-tinted only on the areas specified as white.
For quick tests, you can use the following values in the 4 channels
of your S/O/E/G texture:
•
The red channel (used for Specular): all black
•
The green channel (used for Occlusion): all white
•
The blue channel (used for Emissive): all black
•
The alpha channel (used for Glossiness) all black
You can look at the template folder, which include example
textures that you can reuse for quick tests on your own pieces.
PIECE DIMENSIONS SPECS
PIECES DIMENSIONS SPECS
• These values are measured
precisely for the bounding box
around all colliders of the object.
• The actual mesh inside can be
taking a slightly smaller or bigger
amount of space, such as for a
crumbled wall or slanted roof.
• The prefab can use multiple
colliders as long as all of them fit
within these dimensions.
