Objects are "smoothed" and textures don´t appear.

Unity Engine
1

I have a problem with my .blend objects (from Blender 2.49b). When i import my object to Unity, the object is “smoothed”. In Blender it was not. In Blender it has nice sharp edges. Can I make my .blend objects in Unity back to “sharp”?

And other thing is, when I try assign the texture to my object, the texture doesn´t appear. It is just a solid color. I have read somwhere on this forum, that it should be done manualy. Please, can someone explaint to me, how exactly have I do this, please?

Thank you very much.

I had the same problem when I first started with Unity!
For the smoothness, when you first import the model there should be a slider labled Smoothing Angle. This slider is how smooth or sharp your model is. When you first import a model this slider is greyed out, what you have to do is check the calculate normals box right above it. slide the slider down to about 36 (play around with it) and then push aply at the bottom. your model should now look how it did in blender when you place it in the world!

for the textures you are going to need to learn how to UV map in blender. here is a tutorial.

if you need more help with UV mapping I can explain it to you via E-mail,
Good luck!

Thank you, now the objects are nicely sharp and the textures appears in Unity too. :smile:
But let me ask you just something. If I figured that out right, the “clasic” texture mapping is only for rendering in 3D modeling program but for real-time it needs to be UV mapped? What is the differ betwen these two mapping techniques? Because when I mapped it by the clasic way, the texture doesn´t appear in the Unity, but when I use the UV mapping, the texture on the object in the Unity appears. I just don´t understand the differ. And this UV mapping technique needs to be used in the other 3D modeling programs as 3Ds Max or others?

I am pretty shure the classic mapping is only to view it in the modeling program, as sort of example i guess. UV mapping is aplying the texture how you want it while the 3D object is ‘unrapped’.
Yes you have to use the uv mapping tequniques in most or all other programs for unity to be able to see the texture on the model.

Thank you for your help. :smile:
