yea... read the title. i have a model,not to many polys,unanimated and in .3ds i want to texture it(skin it) how... its probably awnsered somewere else but its most likley about warping in 3dsmax5,i use 7 so yea...
First import the model file, but remeber that 3ds file format isn't good at saving animations so don't be suprised when they disapper.
When you import the model click Modify Panel -> open modifier list and click Unwrap UVW. Click Edit and in the new window open Mapping -> Flatten Mapping and set Spacing to 0.2. Face Angle Threshold is less important, type a number between 30-90 degrees.
