How do I make a rough plastic surface?
I created a bottle.
I need to make this bottle like in the picture. How to make these rhombuses like in the picture?
If you want the "smooth" areas with a pattern like in the image, you can mask some parts of your Bump Map by multiplying it with a (rotated) checker texture. You will probably have to make a lot of transformation adjustments (size, rotation, location, etc..) before it fits your project perfectly, though:
