I've been using Blender for few months now and really really loving it otherwise but trying to understand how textures work in blender is making me want to give up. I mostly do just architectural stuff and I still don't understand how to set exact sizes for repeating textures (e.g. brick wall texture where I know the physical sizes) and how to get them stay the same size when used between different sized and shaped objects.
Most times I've just used Cube Projection and then have tried to adjust things by hand but it just seems like a lost cause.
Is there some simple way to achieve this or any plugins that could be used for this?
