hi guys, thanks for all the replys. Prob frustrating not knowing what Im on about.
But CTBRAM showed an example of exactly what Im after.
However instead of drawing the bump in photoshop - this tutorial Im doing actually builds the threads first and then uses them for them to create a new bump map file - thus enabling him to delete the detailed polygon threads and just have a nice detailed bump.
He places a plane under the spread out threads and creates two obj files for each - like normal mapping I guess, but creates a nice bump map file in this other program.
Id like to be able to do that within Maya.
sorry for the long drawn out process.
