Transition Tile Maker
This week, we're glad to release another standalone tool to help you build assets for your future Metaplace worlds! Here is the Tile Transition Maker.
-----
The Tile Transition Tool helps you make transition tiles between two different terrain textures. While a client engine might support procedural blending between two different terrain textures, there are effects you can only achieve by providing a set of transition tiles. This tool makes it a snap to generate the full set of transitions you might want.
How To Use It
Adding textures
You select which slot to drag a texture into by clicking on it. The selected slot will be highlighted red.
You can import a texture into a slot by either dragging one in from the desktop or by choosing Open... from the File menu. The new texture will be put in the selected slot, replacing whichever texture is there.
You'll get a preview of what that texture looks like across a 5x5 grid in the preview window, so you can use this to check that it tiles well.
Note that tile transitions will not support transparency in textures, so if you drag in a texture with transparency, it's going to get a black background in the generated transition tiles.
Deleting textures
You can delete a texture from a slot by choosing Delete Texture from the Edit menu, or hitting the Delete key.
Masks

A pulldown in between the two texture slots provides a set of default "masks." These are premade patterns that set up the ways in which the two tiles will blend. You can see a preview of the way the mask looks right under the pulldown.
You can also cycle through the available masks by just clicking on the previews.
Generating Transitions
Click the Generate Transitions button, or hit the space bar, or choose Generate Transitions from the menu. The twelve transition tiles will appear in the transition slots, and a composite preview will appear next to them displaying what the transitions and tiles would look like in actual use.
Once you have generated transition tiles, the Save Transitions button will be grayed out.
Saving
Hit CTRL-S, press the Save Transitions button, or select Save As... from the menu. Type in a filename and select a directory. Twelve textures will be saved in PNG format at 64x64 pixel files.
There is a pulldown next to the save button that lets you change the size of the saved tiles to other values instead.
The resultant filenames will automatically have numbers appended to the filename you chose.

Using Your Own Masks
This is an advanced feature.
You can add masks to the tool by clicking the Add Mask button. You will br prompted to select first a corner texture and second a straight edge texture.
Once you add a texture pair, they will be added to the pulldown menu.
We suggest you keep these textures in the folder where you keep the tool.
If you select a mask that you added, the Delete Mask button will become available.
Custom mask entries are saved in a file called transitions.ini in the folder where you keep the tool. You can edit this file by hand, if you want. The entries consist of a name for the mask pair, and the two filenames.
Masks will be automatically resized internally to be 256x256, so for pixel-perfect purposes, you probably want to start with them at that size.
A mask image should be a PNG with transparency; we suggest that you make the opaque color something easily visible against both a black background and against a transparency checkerboard grid in your preferred graphics package (we picked red, but it could easily be any color you wish).
I
n your graphics program, create a new file, 256x256. Make sure you create it with transparency as the background. Then You can create the opaque portion in a new layer. Your corner mask should have 3/4 of the image covered, but it doesn't really matter which 3/4. Same goes for the straight edge.
The inverse corner texture will be generated procedurally by inverting the corner texture, so make sure your corner textures are symmetrical!
Make sure the masks tile to each other as well. The preview image when you generate will be helpful in this regard.
