[Solved] Parts of textures exporting as Black?

Recommended Posts

Hi Guys,

I am urgently trying to finish some work and yet as you can see the textures where there is grey metal export as solid black.

Does anyone know why this may be? As you can see from the UV layout from within Coat they are displayed correctly.

I have also included my export settings.

Many thanks.

The black zone is the metalness, cycles principled shader support it ?

If not you can change the workflow here: (remember to change the workflow option on export window too)



Thanks I will try exporting individually, I know what you are saying about the metalness but it shouldn't be exporting this on the diffuse texture should it? As you can see from my screenshot of the diffuse, its overwriting the grey metal colour with pure black.

Deselect export constructor shown in picture. You will get a new menu.

Make sure "Store gloss/roughness in Metal alpha is deselected.

This will export all your maps correctly. 

FYI. Currently the new Principled Shader in Blender Cycles appears not to read the roughness map as we see it in 3DC. I had to adjust my roughness map externally to match 3DC's viewport.

Yes, something appears not quite right with the export constructor for Blender Cycles.



Great thank you, I will use these settings. I noticed that too with roughness. I use the RGB curve node within Blender to tweak it to match.
