Hi there, today I want to share some of the steps to do a CGI dna strand .
First of all searching for references is the first step to start with any 3d model creation , much more references you found and much clear you know what to do .
I started creating a low poly version of the strand creating Cylinder and Helix to fit the right shape of the strand.
After I finished to tweak with the helix shape and cylinder placement I sent to Mudbox (as FBX format) and I retopologize and create UV maps for all the scene object.
I started to sculpting details, I added subdivion surface and I used the sculpt tool with a stamp that add some interesting noise on surface .
After some hours of sculpting , I started to paint to texture using a background color and second layer using a dry-brush tool to give life to details.
For animation or slow workstations uses I suggests to extract normal maps to a low poly version to avoid lacks or slow performance.
After that send back the model to Maya and I setting-up the lighting and render setting.
That’s the result :
Hope that you like it.
