To make cross-bar windows in TSG Roblox, build the window frame with parts, then add two thin bars inside it in a cross shape, and finally place glass behind them so the opening still reads as a window.

Simple build method

  1. Make the outer window frame from a block or a few thin parts.
  2. Add a vertical thin part down the center.
  3. Add a horizontal thin part across the center.
  4. Put a transparent or lightly tinted glass part behind the bars.
  5. Duplicate the finished window for other spots in the build.

Cleaner look

  • Use slim parts for the bars so they do not feel too thick.
  • Keep everything aligned to the same center point so the cross looks even.
  • If the window feels bulky, shrink the inner frame a little for extra detail.

In practice

A common approach is to make one finished window model, group it, and copy- paste it wherever you need the same style again. That is usually faster than rebuilding each window from scratch, especially for repeated house or base designs.

Extra detail

If you want the window to look more polished, use a separate inner frame around the glass and keep the cross bars slightly inset rather than flush with the outer frame. That gives it a more realistic layered look.

TL;DR: Build a frame, add one vertical and one horizontal bar, then place glass behind them and duplicate the model as needed.
