Exporting raw voxel color

[candela]

Hi,
3DCoat can export volume densities in a .rawvox file using the option "export raw voxel object" in the sculpt room.
Is there a way to also export the voxel colors in a similar format after brushing them on in the painting room ?

We are making an online game with destructible voxel objects and we directly import the .rawvox files into UE5.
I'm trying to make the voxel objects look better and having voxel colors would be a great starting point.

Thanks,

François

Version 2024.27 is out !

The RAW voxels export/import (useful to bring voxel to any your own engine) improved, now it may export import PBR data (color, gloss, metal).

This is important because this is the only way to get this sort of raw information out of 3DCoat.

Hi 

raw format is very simple, just values in 3D-grid that are set as bytes, words or float

___________________________________________________________
byte 0..255, 128 means surface
word 0..65535, 32768 means surface
float 0..1, 0.5 - surface

rawvox format

int Magic ‘RVOX’
int SizeX
int SizeY
int SizeZ
int bits_per_voxel - 8,16,32, 32 means float values

…raw voxel data…

Hey Carlosan, thx for your time.
So is there an option to export the voxel colors instead of the densities ?

Please share your current 3DC>U5 workflow to test it.

* I only found this plugin to import voxel colors

https://docs.voxelplugin.com/v/1.2-legacy/core-systems/voxelworld/import-content

Right now the workflow is as follow:
- voxelize a fbx mesh in 3DC
- paint the voxel colors
- export to a .rawvox file
- directly import to unreal using a custom import script that I wrote
- generate the voxel mesh at runtime

The .rawvox file doesn't contain any color information. If there is a way to export them, I can modify my import script to load them.

Please write directly to dev team at andrewshpagin@gmail.com asking for this request

Thanks

Will do. Thx for your help
