VOXCONVERT: Converted VXMs Rendering Certain Colored Voxels Incorrectly #117

Closed LordKromdar closed 2 years ago

LordKromdar commented 2 years ago

Certain colors are displaying strangely in converted VXMs. Original vox, palette, and converted VXM attached in zip.

Problem is solved by using a different palette, but using the original palette in most files results in these voxel bars

mgerhardy commented 2 years ago

Can you please post the exact commandline you used to convert the model? Did you try --src-palette?

LordKromdar commented 2 years ago

vengi-voxconvert.exe --src-palette --export-palette --force --merge --flip x --input original.vox --output converted.vxm

mgerhardy commented 2 years ago

Most related to the fact that VXM models are using the last palette entry for empty voxels - while we are using the first one (more or less - we are using the voxel type Air with palette index 0)

This is hopefully fixed now. If not, please re-open
