Color from PRT loader

[shadowkiller]

Are you using the krakatoa prt loader? If so, i save my colors in tyflow via vertex colors and then export your prt with texcoords. It seems to work a bit better for solid colors than using an assigned material. If you want to mix the vertex colors you can use the properties transfer operator.

P.S. Just remember to enable the vertex color display on your tyflow object in order to see the correct colors in the viewport.
