► Texture Projection: Part 3 of 3 — Fixing normal maps on triplanar projection.
This is a follow-up to the video about Triplanar Texture Projection in Unreal materials. Many of you might’ve noticed that that technique doesn’t work well with normal maps. Now I’ll show you how to fix it.
What you’re here for starts at 34:54. But if you want to understand why you should follow those steps, watch at least from 14:15. If you’ve never learned about triplanar projections, either watch the second video of this series or start from 02:01 on this one. I’m not explaining it in details, as on the previous video, but I still did it from scratch here.

Disclaimer: my mic was briefly failing now and then, when I changed things in the material and it recompiled. I believe it’s all still comprehensible. Nonetheless, if you have questions, don’t hesitate to ask them.
