Essential tool (fBlender)

[daspex]

I second that.
I have at least 10 rooms made in Blender (latest version), that I wish to convert into addons, but I simply cannot due to the lack of tools/updated tutorials.

Just Export the room AS scene.dae and convert it to an addon with ctk tools.
Its pretty simple.

Since we have the full Version of h5 downloadable here there is no need
for VX at least.Just extract the room out of the game.
You will find a 3d Screenshot of the room in the games binary folder.
Load the .obj file inside of it Into Blender or your favorite 3d editor and rename
all .dds files in the filelist of blender /Your Editor to .png and save it AS scene.dae.Now convert all .dds files from the screenshot into .png files.Then use one of the predefined ctk batchfiles to Compile it Into a custom addon and thats it.
AS for renaming the file extensions in blender ,there is a renaming Plugin available
at the Blender community.
