I made Raptor for a tutorial to teach ZBrush at HAL Nagoya, a vocational school in Japan.
Making it was a fun time anyway.
The scales are handmade one by one. No mask is used.
I did not use UDIM for the texture, but I think it turned out good. I would like to make a dragon next time I make a reptilian model.
I usually use V-ray for rendering, but for this project I used Arnold. I was surprised that the Displacement was much easier to set up than I expected.
