Hi, thing on screenshot(made ingame) was made from blocks like in minecraft. every block has same shade, shade rotates with the block. how to remove it?    

Hi dziablo, I'm guessing that's a normal problem. Check the normals on your cube.

I dont understand what i have to check, can You explain more? Sorry im newbie :S

Which 3D software have you used to create/export you cube to esenthel ?

oh sorry forgot to mention its blender and i exported it to .obj

Do you have a feature in blender to set vertex's normal to its normal position ?
If the normal's orientation has been modified (smooth/blend) it modifies the reflexion/diffusion of the light

im not changing it to smooth/blend, in fact im only putting texture on cube that loads on start and exporting it to obj.
Now i made new project with world and cubes(not even texturing it) and it looks like this in world editor:
   

Can you please provide the .obj file ?

ok so i downloaded alternative to blender "SketchUp" and reproduced the problem, then i found there oprion angle between normals and set it to ~90 and now it looks like it should, but where to find that option in blender?

Model is correct you must include normals in export settings in blender. I use settings like this:

http://wiki.blender.org/index.php/Doc:2..../Smoothing
http://en.wikibooks.org/wiki/Blender_3D:...nd_Shading

.. basically it has to do with your vertices (if they are shared or separate) and how normals are calculated from them.. Try to set face/vertex normals in blender to fix it, or if you simply break the edges on your cube the "problem" should go away - that's what some 3D apps do when you apply auto-smooth/face-normals/smoothing-groups or whatever they like to call it, they split the edges of the mesh based on some criteria (face angle)

-edit: and as Seba pointed out, don't forget to export normals properly (always check first)

Thank you for help and tips. Its all good now
