IDK if anyone is interested! but here is some insights into my process making these kind of realistic animations.
Sculpting process. Luckily i already had a basic rigged figure with vampire hands (it was Armands) so i just swapped out a Lestat and Louis head I had previously made. I've made a number of animations of porcelain music boxes so i have a decent pipeline. I model all the clothing pieces separately and then remesh all of the pieces together. I generally will keep the hands and head separate to make texturing easier. Blender has a decent remesh modifier but has often caused my computer to crash if it doesn't like the geometry; getting a clean remesh also is a bit of a trail and error and generally requires cleanup. After i remesh all the pieces, I export them to a program called Instant Meshes - this is another remesh program that is better at retaining fidelity but lowers the poly count of the object. I like to keep the poly count at a reasonable level to make uving easier. Worrying about clean topology here however is not as important since these will be static.
After uving i export to Quixel Mixer, which is a free texture program from Epic Games. Its been beta for years, which is a shame because it has potential to be a great program. It can be buggy but the results are pretty good and it has many preset smart materials that i often just tweak a bit to get the desired look. Here are some of the references i was looking at for texture!
I noticed the costume designer put Lestat in mostly gold accents and Louis in silver accents, so decided to do the same.
thanks for reading and for the support on the animation! It was fun to make!
