Hello !
everything was working fine until last month.
I make all my objects and texturing in blender. all my objects are using only 1 texture (its a color palette ) and on top of that i am using a material that pixelate that texture (created by my friend )
and with last few exported items . mostly large objects like buildings ETC
those pixelated textures are streched ( screen shot in the attached image )
i dont know what caused this problem especially because i didnt change anything in blender and dont recall changing anything in UNITY3D editor .
Thank You kinfly for all Help .
Daniel
