Hi Jeremy, thanks very much for taking the time!
What I have is basically a T-shirt with a nice substance for the main material, and I want to add another substance to give the T-shirt 'thickness' and the feel of a real T-shirt border all around.
As this needs top-quality rendering in Unity, I'm a bit stumped on how to approach the normal map generation... or whether to just create a grayscale bump map and let Unity convert it to a normal map?
The overall idea is in 3dsMax to simply assign this border substance to all my borders (approx 1.5cm wide by 2mm thick in the border mesh all around the shirt) and I get in Unity a nicely rendered border!
(For example, the UV mapping for the border that is 1m long all around the shirt would probably use the same substance texture about 50 times with the total substance representing a real-world area of about 2cm by 2cm)
Should I go with grayscale bumpmap or attempt with normal map??
Any reference substances that attempt borders in clothing??
Thanks!!
