Normal & Tangent attributes #88

Closed StjerneIdioten closed 3 years ago

StjerneIdioten commented 3 years ago

The Vertices element has a normal and a tangent attribute, which is just always set to true. But there might be cases, where they shouldn't? So investigate what these attributes actually do (I believe it states that the normals are there and defined in tangent space)

image Apparently having tangent turned on is a no go for triggers

StjerneIdioten commented 3 years ago

A way around it could be a trigger option, just like the one for fill volume. Which toggles tangent and normals off. At least until further info surfaces about these options.

StjerneIdioten commented 3 years ago

If a material has a normalmap, tangents is on. If no normalmap is present, tangents are off.

StjerneIdioten commented 3 years ago

Tangent has been figured out as per previous comment. Normal is still up in the air, but I will close this issue for now as there doesn't seem to be an issued with it being there (at least not discovered yet)
