Converting a FBX / OBJ, resulting VOX file is too small to use. about filetovox

You can import your 3D model if you want with MeshSampler and manually set the distance from the object to improve the capture part. Save the result and import it for FileToVox.

BUT MeshSampler is very experimental and it won't give you good result. You can instead use CloudCompare for doing the same task but with better results. I've done a video tutorial, which is on the wiki.

MeshSampler is having a massive rework. Should be fixed in FileToVox v1.14 with the release of MeshSampler v2

Sounds promising. Right now I've switched to obj2Voxel for the time being. It does what I need pretty well.

MeshSampler v2 is released and bring better voxelization for 3D models, you can download it in the release section.
