the generated blocks are very few and voxel is very tiny • SOLVED

hello @Zarbuz ,

i am on macOs 10.15.7, and used the lastest release of FileToVox with this command: ./FileToVox --i /Users/sylvainfiloni/Downloads/rainbow\ 2.ply --o testvox3

I wonder why the vox file generated is very small, with a very low value for blocks. Here is the console output with the “rainbow 2.ply” file

What did i do wrong ?

You must specify the grid-size : --gs 256 for example

Thanks Nicolas, i close this thread, as you solved the initial issue, and will open a new one if i can’t handle the color related one 😉
