Renders Isometric Maps!

**Location:** Utah, US

GubiD's Isometric Map Renderer
Version: 1.0
By: GubiD

Introduction

This script takes an isometric map(predetermined by the isometric view script) and renders you a png of it including heights. This makes it easier to develop isometric tilesets and overall isometric maps. Cause it does all the placement etc for you.

Features

Renders Isomap to PNG file
Replaceable default tiles (IsoNode.png in the Pictures folder)

Instructions

This script has a couple of requirements:

SDK
MACL
Isometric View

It would be best to use the demo, but you would simply place this script in a project with the above required scripts (which are included in the demo) and transfer your player to a map including the name of ISO and it will be rendered for you to the Graphics\IsoMaps folder of your project.

Compatibility
This will not work in VX

Credits and Thanks
Makers of the SDK and MACL for giving me the ability to write to PNG file.
McCaladtogel for his original Isometric script, which I modified into Isometric Views (XP/VX)
Seigfried for his help in nailing down Isometric height movement.

Author's Notes
This script is only for RMXP and cannot be used inside of VX. However you can render your maps in XP, and import the made tilesets to VX.
I dont know of any compatiblity problems. However do keep in mind that this script displays 100's of sprites on screen at once. This causes major lag, but shouldnt really matter, because it is intended for game dev only. As in to render the maps for you, so that you can turn them into what you want.

Terms and Conditions
Intended for Development use only(cause its too slow otherwise). Please do not repost this script elsewhere without my permission.

Quite impressive.
I already was planing to use the GTBS after you added the ismetric battle with height, now with this script it would be easier to create the maps.

Thank you for the comments. I hope to see some new iso tilesets evolve from this. At least that was my main goal. Plus it saved me huge amounts of time while making some of mine. I will release them once, I have polished them up a little bit.

Wow, this will be abundantly helpful for tileset creation. Thank you very much for making this.
