bowplane- Thank you, I used alpha 58 in zbrush for the scratch on side and on the rest of the armor as well. I used that alpha with the standard brush with freehand on.
After the decimation, just drag weld the triangles decimation master produces. In Max, the "optimize" tool under freehand category, will solve the problem in a single shift-drag :)
@zachvance hey thanks for feedback. I freehanded the perspective there and yes the tower is a bit off... We shouldn't see the part under the top platform, working on correcting that. cheers!
If in doubt, F1. IT's among the different selection modes - rectangle, circle, polygon, freehand, paint. Paint is the one closest to what you want I think. Good luck!
