KPUT - Material import tool for Blender with UDIM support (Substance Painter compatible)

Addon able to create multiple materials from texture maps, with UDIM support. Compatible with Substance Painter.

I had issues importing UDIM based materials from Substance Painter in a convenient way, so I wrote this. Still in development. Hopefully won't be needed soon.

Substance Painter example:

Usage:

Select the directory with all the texture maps, then click import.

If you want to replace the current materials with the new ones, select that option. Otherwise they'll be added as additional materials, with a "_imported" suffix.

Naming Guidelines

For the import to work, use the following naming convention (substance painter standard):

MATERIAL-NAME_MAP-TYPE

Examples:

Skin_Roughness.png
Skin_Opacity.png

For UDIM textures, make sure they end with a tile number of the kind:

Skin_Roughness_1001.png
Skin_Opacity_1003.png

Good to know

In order for Blender to recognize UDIM textures, it seems that currently (2.9) there has to be a 1001 tile present. To deal with this, the addon will create blank 1001 textures if one isn’t found. You can disable this in the Advanced options section, if preferred.

Current Limitations

Currently only supports map types:

Base_Color (albedo, diffuse)

Roughness

Metallic

Height

Normal

Emissive

Opacity
