To be honest, even if it's not the total desaster I thought it was and stuff like %[var_name] exists, it's still so extremely annoying to type and use that I'm happy to have made me that helper extension to never look back.

Thanks a lot
For the grass I plan to have different options, especially for people who prefer checker-board grass coloring instead of bars. But I could also make texel size and noise configurable, thanks for the idea!
