everyone I would like to know with fundaments , the relation between pixels and blenders's units for meshes over a custom grid's floor ( In my case I use the default grid floor).
I mean this steps (my target is create a tileable wall) .
2 - Then I decided to go blender with my 640x640 image put it as background image .( The purpose is create tileable textures ) as you can see , the measure of the mesh is " 1m = x , 2m = y , 1m = z , and the scale is applyed to 1,1,1 in all axes) and as a remainder, the grid floor is by default (check it below) .
3 - so my conclution is false? 1 meter in blender is 64,64,64 pixels ( please let me know if I am wrong , consider the resolution of the image is 640 pixels with 72 ppi as in the first picture )
4 - I think my mesh is ok, at least ,it matches with the default grids and the image on the background.
