Ceiling grids moving when rendering

[gbrowne]

This may appear a dumb question, but why when you do a ceiling grid in shading with lines, the light line up with the grid, but when you render, the grid changes to another location. Any ideas?

It is to do with the mapping of the bitmap that the render engine uses to represent ceiling tiles and is independent of the drafted grid. You can tweak it in the materials editor by adjusting x and y offsets for the bitmap but this is a trial and error approach.

If you do do this duplicate the material first so that you only use it in the current project.

Thats a bit of a shame, but thanks for the tip.
