I’ve been trying to make a 3D tileset in Blender and export it into Unity so I can make a level editor that will help me save time and effort designing levels by reusing the same tiles.
It’s been working pretty well so far, but now it seems like one of my tiles is having some trouble.
I attached the same material (Mobile/Diffuse with a texture referenced) to one of the tiles as all the others, yet the texture seems to be pointing in a different direction with one of the tiles than it does with the others. The seams for UV mapping in Blender are set to the edges of the square which is having trouble.
The normals of the square are pointing up, like all the others, yet it seems like it’s somehow facing a different way.
Could it be because in Blender I rotated a duplication of a similar tile and set it in the proper place instead of making it from scratch? If so, this should probably be a Blender question…
Any help on how to fix this would be appreciated! I would attach an image, but it seems this function is broken on the website or something…
So normals…
They are really ****** annoying.
In blender go into textured mode to see the normals if they are not right go into edit mode and select everything and press CTRL+N this will recalculate the normals. If you keep problems with annoying parts select the parts and press CTRL+N or if that doesnt work you will need to flip them go to:
Mesh >> Normals >> Flip normals
Or check the doubles… W >> Remove doubles. Srry if I over-explained…(if thats even a word or you alrdy did this).
By “facing a different way” do you mean it’s rotated to run the wrong direction (Left to Right or Bottom to Top instead of Top to Bottom)? If that’s the case, it’s the UV coords. If you unwrap, then rotate, the texture rotates with you – that’s a feature.
Re-“unwrap” the rotated tile, or manually rotate the uv-coords (both in blender.) For rotate, you can just start spinning then type “90” to make sure it’s exact. If it’s 180 degrees the wrong way, on Unity you can change that material offset to -1.
Or do you mean the tile is invisible unless you look at it from behind. Then it’s just flipped normals, telling you the back is really the front.
