Piranha4D's Learning and Practice 2023

2023-02-20 (Commercial) Course: Shader Magic in Blender

#18 Image texture.

This is a generally good introduction, if a little short at times on showing rather that telling. On the other hand, there was more showing than I expected for explaining colour spaces, which was nice to see and very clear for beginners. Nothing I didn’t know already; this amazing thread on the development of Filmic V2, while I only partially understand what they’re talking about, has nonetheless taught me a lot.

So whenever Joakim didn’t show something I decided to make it happen for myself, using more appropriate textures instead of using the same one for every form of mapping. Better for remembering.

From left to right:

  • generated, spherical mapping (texture from NASA)
  • UV, flat mapping
  • buttons are generated, flat mapping
  • roof is partially UV mapped (texture from textures.com), with extrapolation past image bounds set to “extend” so the final colour pixels get extended on the non-mapped edge faces
  • can is generated, tube mapping
  • door uses two textures, decal is generated, flat mapped with extrapolation past image bounds set to “clip” so the decal doesn’t repeat if the base image does.
  • backdrop is generated, box mapped

It was a good lesson.

Music: Bhangra (unlike Trudeau I can’t dance to it, but I can bop in my chair)
