Homework Submission – Week 4 – Vase B
Not too much different from last week, but with a few added details and polish:
I started by tweaking the normal map for the high-poly model; sharpening the horizontal bands slightly and adjusting their scale, as well as reworking it to only use a single Bump Map node instead of some kind of vector math abomination. Also featured is the change in the Specular value of the shader to a better, lower number.
I also noticed that my glaze mask had a few patches that weren’t entirely white from the texture painting process. They didn’t have any serious impact on the current materials, but I figured I’d take the opportunity to fix them while I remembered.
I adjusted the colour slightly to add some variation to the glazed portion in addition to the non-glazed areas.
After some experimentation I came up with a passable system for adding some roughness to the surface of the glaze. I’m not 100% sure whether I think it’s the best way of doing it just yet, but I’m curious what other people’s opinions are!
At this point I began re-baking my changes onto the low-poly model. For the normal map I had to make sure to disconnect the clearcoat normal nodes so that only the vase itself would be baked to that particular layer.
I was also able to solve the issue of the low-poly clearcoat not matching the sculpted shape of the vase by doing a second normal bake with the high-poly normal nodes disconnected and the clearcoat normal nodes connected to the standard normal input, producing a second map which I hooked into the low-poly shader. The majority of the texture is black here because I forgot to switch off Clear Image in the bake settings, but the current version in the Google Drive doesn’t have this issue.
All of which produces this as my ‘final’ submission! On the whole I’m quite pleased with how it turned out, though I might go back to it in the next week or two in my own time and see if I can add any more scratches or imperfections to the surface.
Here’s the same image with a blank background for @splat21 – I’m also planning a proper render/video in the near future, but that requires me to set up something a little more permanent than the Blender studio light so I don’t quite have the time to do it tonight.
