usely i use "export as lwo" which brings my all the maps etc...pretty simple.... sometimes, in modo, i tweak/paint the colormaps...
the skull is just as obj-hires mesh export (500 poly)-->load into modo--> add shader with noise bumpmap --> press render...
the sculpt of the skull and render it are done in 20 minutes. sometimes, i dont wanna waste time with UV,s etc, just see my ideas in quick rendering...
i am using modo5 of course...
anyway the pumpkin and the eye also rendered in modo. displacment maps, color maps etc done in 3d coat and export lwo into modo.
