Background, Floor, and Frame #

The main subject in a voice interaction is, of course, the CG character itself, but ancillary information such as the background and frame displayed on screen should not be neglected. Just as a person’s clothing affects the impression they give, what you display behind or around a character influences the overall impression.

This section describes MMDAgent-EX features related to scene settings other than the CG character.

• Space color
• Background and floor images
• 3D stage
• Screen frame

Space color #

The default color of the space (the color of empty space) can be set in the .mdf using campus_color. r,g,b specify the R, G, B intensities from 0.0 to 1.0. The default is a deep blue (0,0,0.2).

campus_color=r,g,b

Background & Floor #

You can set or change the floor and background images by issuing the STAGE message. Specify two images in the order “floor image,background image”. .png and .jpg are supported.

STAGE|(floor image file),(back image file)

In the scene, the floor and background are displayed as planes. You can change the size of these planes in the .mdf as follows.

stage_size=x,y,z

x,y,z specify the lengths of the respective parts below. Note that x represents half the width.

Stage model #

You can represent the entire scene using a 3D model for the stage. Only .pmd format (including ones converted from .pmx) is supported. Specify the model file with the STAGE message.

 STAGE|stage/tatami_room/tatami_room.pmd

Note: when a stage model is used, the floor and background are not drawn.

Below is an example when a sample in the Example stage folder is specified with STAGE.

Window frame #

With the WINDOWFRAME message you can overlay any PNG image across the frontmost area of the screen. Transparent PNGs are supported, so you can use a transparent image to place a frame over the screen as shown below. Use WINDOWFRAME|image filename. Examples:

You can switch the displayed frame with WINDOWFRAME|another image filename, and remove it with WINDOWFRAME|NONE to return to the original state.

To layer multiple images, use WINDOWFRAME_ADD. Add with WINDOWFRAME_ADD|name|image filename. Using different names stacks images; specifying a different image file with the same name replaces the currently displayed image.

 WINDOWFRAME_ADD|frame1|images/frame_trad.png

To delete a frame, use WINDOWFRAME_DELETE|name to remove the frame with the specified name.

 WINDOWFRAME_DELETE|frame1

Alternatively, use WINDOWFRAME_DELETEALL to remove all frames at once.

 WINDOWFRAME_DELETEALL
