This mod allows generating init.lua files of nodeboxes automatically using the sproxel 3d editor

http://sproxel.blogspot.com.br/

The texture generation is working correctly now, the plugin generates six ppm files that should be converted to png in order to work with the game (I use irfanview on windows).

place the python script on the plugins folder of sproxel : https://www.dropbox.com/s/526kb9oqm193ma3/mtnodebox_export.py

open sproxel, edit your file and export it, select "Minetest nodebox file (*.*)" as export format and provide a name and a place to export. the name will be ued to create a directory where to write the init.lua file to. That same name is used as modname, while your node will receive a yournode name (making <directory>:yournode the fully qualified name of the node ingame).

Sproxel view:


Save as:

(Do not append a file extension, the name here is used as a directory name and as mod name).

Ingame:


TODO: Optimize nodebox by joining adjacent blocks (i need a good algorithm for this).

Nice.

This should probably be in related project, though.

This seems promising in that it is easy to save and load your models. However, it seems like while with ruben's tool I can create a model with just 3 large nodeboxes, using sproxel I would need to have nodeboxes split into many smaller boxes. For example if I start with a 16x16x16 grid, I would not be able to join these nodeboxes into a simpler nodebox even if several small boxes made up one large nodebox.

for example a 2x2x2 nodebox could not be combined into a single nodebox, but instead would be represented as 8 smaller nodeboxes. Where with ruben's tool, I just make a large box by dragging the edges because I don't need to break the nodebox into a grid. Is my thinking correct on this?

Sadly without GNU/Linux support, so it’s nothing for me. :-(

@Neuromancer

yes, but this is a "true" voxel editor, each "block" is a 3d pixel, a voxel.

If/when the thing work correctly, the texture is created right from the voxels by projecting the voxels on a plane corresponding to each texture, so instead of creating seven separate art elements (nodeboxes plus each six textures) you do everything in just one go.

@wuzzy are you sure sproxel is windows only ?

it is qt based and uses python as scripting language... this looks like something very much linux friendly...

I need help figuring out sproxel coordinate system and mapping it into minetest coords

Example of what can be done with sproxel :

Made the texture generation "work". But theres a lot of artifacts when voxels eclipse each other in relation to the box sides. I believe this is a problem with minetest renderer...

Why is no one interested in this tool ?

lol

not true :-)

have built some blocks with it.
Minetest Logo Display Block as example:
Model in Sproxel
result ingame

Problems:

• had to convert some of the textures to work
• had to adjust the mapping of the textures as they were all over the place
• the resulting structur was mirrored or flipped or whatever so had to tweek that

sadly I never got around to document (or fully understand) what I did, so I never posted comments :-(

....but when Rubenwardy asked for suggestions for his NodeBox Editor I did name the Sproxel format as import possability (see discussion on IRC, scroll up and down a little to se the full context and his remarks)

Although their Google Code site has no LInux binaries, they have instructions for building on Linux.

Please, does anyone have a copy of the python script, the link seems broken.

This one seems to be the last one I downloaded :

Thanks!

VirtualBox is your friend :) that how i run all my windows junk, I keep my little pet Windoze XP in a nice little box where his viruses and problems will not affect my good day :)

does anyone still have this plug in?
