Decal Stamps†

Decal stamps allow 2D images to be projected onto terrain and models.
It is easy to understand if you imagine a scene where images are projected onto a wall or other surface using a projector.
Decal stamps can not only be placed on maps as objects, but can also be used as graphics for events.

Decal Stamp Setting Options†

Decal Stamp List†

This is a list of registered decal stamps.

• Add Button
  Add a decal stamp.
  Only materials that have "decal shader" specified as the shader in Resources > Materials will appear in the Asset Picker > "Ready to Use" tab.

• Folder Button
  Add a folder to manage stamps.
  Multiple selected stamps can be grouped into a folder, and stamps can be moved by drag & drop after adding a folder.

• Copy Button
  Copy the selected stamps.

• Paste Button
  Paste the selected stamps.

• Trash Button
  Delete the selected stamps.

(!)Newly added decal stamps are placed in the Map Editor > Stamps Palette > Objects tab.
If you create a folder in the Decal Stamp List, the created folder will also appear in the tree on the Objects tab.

Decal Preview†

The decal selected in the list is displayed.

Decal Settings†

• Name
  Specify a name for the stamp.
  (You can also change it by clicking twice on the stamp name in the Decal Stamp List.)

• Material Name
  This is the name of the material being specified.

• Materials
  This is a thumbnail of the material specified.
  Click on a thumbnail to select the material to be assigned.
  You can also use the jump button to go to the setting screen for the currently specified material.

• Width
  Specify a base size for placement of the decal stamp in the Map Editor.
  The "size" of the bounding box displayed during placement changes.

• Elevation
  Specify the base height at which the decal stamp will be placed on the Map Editor.
  The "height" of the bounding box displayed during placement changes.
  The larger this value, the easier it is for the decal to be projected onto a stepped surface.

How to Use Decals†

Creating and Using Decal Stamps†

1. Press the Add button in the Resources > Decal Stamp list.
   In the "Resources" tab or "Local Files" tab of the Asset Picker that opens, select an image/texture to generate a decal stamp.
   A material will be generated using the image you specified automatically in Resources > Materials. In addition, images/textures selected in the Asset Picker will automatically be given the Management Tag #3D and will appear in the Resources > Textures list.
   (!)Note that if you create a decal by selecting an image outside the project in the Asset Picker > "Local Files" tab, it will be registered in Resources > Textures.
2. Newly added decal stamps are placed in the Map Editor > Stamps Palette > Objects tab.
   If you create a folder in the Decal Stamp List, the created folder will also appear in the tree on the Objects tab.
3. Select a decal stamp from the Stamps Palette>Objects tab and place it on a map.
   (!)If you move the camera in the Map Editor after placement and find that there is an angle at which the decal grazes, try moving the position of the decal stamp so that it is slightly pressed against the projection plane.
   (!)When projecting onto a surface that is at an angle or corner, the decal stamp must be rotated.
   Picture in your mind what you are projecting with a projector and adjust the position and angle.

• If you want to project a decal on an object, you need to change the material of the object to be projected setting.
  Select the material of the target object in the Resource menu and turn on "Decal Target" in the Properties.
  (!)If you cannot see the effect in the Map Editor after turning on "Decal Target," save the project, close it, and reopen it.
  This is an existing bug at the Ver. 1.10. It will be fixed in the future.

• The order in which the decal stamps are rendered is controlled by "Rendering Order Offset" in Resources > Materials properties.
  The higher the value specified for this option, the more the decal will be rendered in the foreground.
  (!)If you select decal shader for a material, you will be able to change the "Rendering Order Offset".

• You can "Convert to Event" from the context menu by right-clicking on a decal stamp placed on a map.
  Alternatively, click on a decal stamp and press the hotkey "T" to convert it into an event.
  (!)Converting a decal stamp to an event changes the way "Angle" is taken.
  When projecting a decal against the ground, the decal stamp projects the decal at angle X = -90°, but when eventing, the decal is projected toward the ground at angle = 0°.

Notes on Decal Stamps†

• Impact on Decal Processing Load
  Using large sized images as decals or using too many decals can increase the processing load.
  Please note that this will increase the processing load on the GPU. Please perform a test play and check the GPU load with type 2 of the Performance Meter.

• Decal Projection
  The way the decal looks is related to the material (decal shader) settings, the Rendering Settings of the map on which the decal is placed, and the settings of the lights placed on the map.
  Adjust the visibility by tweaking the various settings.
  (!)The F7 key is the hotkey that opens the Resources menu. This key is useful when switching back and forth between the Map Editor and the Resources menu.
