![]() ![]() I have read somewhere it's useful to guess cross product results. So I have absolutly zero idea of the meaning of this thing that everyone like to talk about for obscure reasons. But in Unity the Z would be the index if you point forward with your hand. Wikipedia talk about rotation around the Z axis for the thumbs up. I have searched for the meaning of the "left or right handed" thing : It is not clear at all what these thing are and what are their final utility here. Unity is +Z forward, but the front view awkwardly shows you the back of the UI. (in the case that we have to give a face to something, like a head). To my understanding, Blender is +Y forward, and forward mean this is the direction you look when you work, and your work is facing you. (by making forward = -Z and up = +Y in the fbx export setting, and apply transform).īut following the fact that the forward is YOUR forward, keeping the monkey facing the same direction would means make it looks toward -Z direction in Unity (by making forward = +Z and up = +Y in the fbx export setting, and apply transform). Most tutorial/"docs" I found tries to make the monkey looks toward the +Z direction in Unity, which is the first intuition I mentioned at the begening. No consensus either for choosing the right settings. What a big confusion time when it come to export a FBX model from Blender to Unity. Some says Blender is -Y forward with left hand system, other that it is +Y forward with right hand system, same story for Unity. Google gives you any kind of very differents opinions from confidents people. But this subject lacks of consensus and it makes me go into loop thoughts about coordinates systems. The characters are inversed and that makes no sense to me. ![]() In which direction do you have to look to read the text ? In other term to see its front, like if it was the front of the monkey ? What happen if you select the front view in Unity ? OK, so that mean when you work on a model, its front is backward your forward direction. This make sense when you select the Left view, it shows the side of the monkey from where your left is when you look the +Y direction, not the left side from the monkey's point of view. So that means the Forward is the direction YOU are looking. In reality the Blender's documentation mention that the coordinates system is +Y forward. So up axis (+Z) = the direction from bottom to the top of the object,Īnd forward axis (-Y) = the direction from the back to the front of the object. This is reinforced when you select the front view, showing its face. In Blender when you pop the monkey model, the direction it is looking makes you think that this is the Forward direction. This kind of thing looks absurdly easy, BUT ![]()
