H-Mode7

[MGC]

I most likely see it only being for RPGMaker XP as his previous Mode7 systems have been exclusively XP.

Exactly, but when the script is in a more stable version, it will be possible to create a tool to import RMXP HM7 maps into RMVX (like the one for the FPLE).

How high can the textures be?

Not including the map's own heightmap, Map tiles (such as walls) can be up to 32pixels in high. And since you have a upper/lower level system, you can stack one wall tile on top of another. In that respect, you could have a wall two tiles high. Again, not including the map's own heightmap.

Now, you CAN place a map event on top of these, thus making it 3 tiles in height. But you wouldn't want to use map events as tiles as large number of events in a single map can cause undo lag. So right now, you can go 2 tiles (or 64px) in height with no problem.

You can combine the lower part with the ground (instead of transparent areas) to have a third height.

Hmaps can modify the textures?
I made a 3-level home. The first two are the walls, and the third is the roof. If I have the house without the roof, texture looks good; but if I put the roof, texture is distorted. What is the problem?

That's because your roof is a slope, and pixels are determined by independent columns, using the max altitude of each column. Imprecision due to rounded values give this result.

You can try to make 4-sided roofs to get rid of this.





EDIT 09/02/2011 - Version 1.2 :

Mainly fixed the transparency and the blend types for events.
Now heightmaps must be placed in a "Heightmap" folder.
