opengametools VS magicavoxel-shaders

Note for programmers: we use ogt_vox.h from opengametools by /u/jpaver so if you're using C/C++ you should be able to add .vox loading to your code which supports scenes exported by Avoyd relatively easily with this.

Check out ogt_vox.h by /u/jpaver which can read/write vox files.

Alternatively you could load the .vox data with the ogt_vox.h library and mesh it yourself.

The .vox cloud transparency issue was due to me not realising the transparency parameter wasn't set for these, so I had to set it on import to fully transparent. The import order issue was in part due to changes in the opengametools/ogt_vox.h import library I'm using and in part due to differences in the newer .vox file version order or how the import library handles these.

If you can program you might be able to do this yourself using a library like ogt_vox to write out the resulting vox file, along with code like Assimp to import the geometry. If the vertices are all on a unit grid it should be relatively trivial to go through the quads (2xtriangles), calculate the face normal, and modify the voxel just below the quad with the texture sampled from the texture coordinates.

You might find looking at the implementation in ogt_vox.h useful, along with this discussion about the materials.

I took the liberty of writing up a very basic demo of how to do this using the library: https://github.com/jpaver/opengametools/blob/master/apps/voxseparate.cpp - hope this helps.

Are you going to make shaders for MagicaVoxel? Nice! You will need some knowledge of the GLSL language . Some tutorials and articles: https://thebookofshaders.com/ https://mercury.sexy/hg\_sdf/ https://iquilezles.org/www/index.htm https://github.com/lachlanmcdonald/magicavoxel-shaders/wiki/Shaders-in-MagicaVoxel this code was based on the distance map from the shader by Tempally, 2017, which was based on the code by David Hoskins, 2013. You can find the links in the text if you download my file. The source code has been modified and adapted to work with magicavoxel. The controllable parameters were added and tuned and now, , as i think, it's a convenient and useful tool for voxel artists. Thank you and good luck in learning.

Check out these when you are ready for more: https://github.com/lachlanmcdonald/magicavoxel-shaders

You can thank u/mode_vis for those beauts. They have a whole list of different shaders you can purchase and add to your shaders library: https://gumroad.com/mode_vis -- This GitHub account also has a great list of shaders, and instructions on how to add if you're unfamiliar: https://github.com/lachlanmcdonald/magicavoxel-shaders/wiki Also, u/ArtChanny has some of the best tutorials on MagicaVoxel I've found: https://www.youtube.com/watch?v=SYLJ5EVvfVQ&t

Alternatively, you can use Shader (shortcut 'C') brush for quick work. You need to download and install the brick shader first from lachlanmcdonald github.

Thank you, I'm glad you like it. Besides practicing, I would say that experimentation and exploring all of the tools and features that magicavoxel has even if you don't plan on using them at the time, but try learning how to use them all, some are very powerful. Learn commands that could be put into the command bar at the bottom. Also gather up all the shaders you can and learn those as well, some good ones are: https://github.com/lachlanmcdonald/magicavoxel-shaders https://github.com/patStar https://gumroad.com/mode_vis?sort=newest Watching some process videos like those of Knosvoxel or Madmaraca ( youtube.com/MadMaraca ) are great ideas as well though I didn't have the pleasure of having those when I started....they would have accelerated my progress. Also join the Magicavoxelcommunity ( MVC_Discord ) channel on Discord, lots of help and ideas to get and see there.
