12 create minars and complete Gol Gumbaz Model in Unreal Engine

🕌 Session 12 Summary – Final Modeling of Gol Gumbaz Structure

🧱 1. Project Setup

• Opened Golgumbus_part3 project from Patreon zip.

• Deleted temporary projection mesh inside the dome area.

---

🕳️ 2. Cutting Open the Central Dome

• Created a cylinder (radius: 2100) and used Trim tool on main structure to open up the top.

• Adjusted cylinder height to fix gap manually (−40 units on Z).

• Later switched to Boolean (A−B) for a cleaner cut (avoiding visible gap caused by Trim).

---

🗼 3. Creating a Single Minar (Minaret)

• Created a cylinder (radius: 300) as minar base.

• Extended top using Push Pull and scaled upper section.

• Added Insert Edge Loops (8 cuts per side) and selected alternate faces.

• Applied Push Pull (30 units) on selected faces for decorative pattern.

• Created top dome inset using Inset + Push Pull (60 units up/down).

---

🏛️ 4. Hollowing the Minar

• Created a smaller inner cylinder (radius: 290).

• Used Boolean (A−B) to subtract and create inner walls.

---

🚪 5. Adding Decorative Door Arches

• Reused SM_door_1 mesh.

• Scaled down (0.08) and rotated to match each side.

• Placed 8 door arches around the minar using Alt + drag + rotate.

• Merged them into one mesh and used Boolean (Difference A−B) to cut clean door openings into minar.

---

⛓️ 6. Minar Vertical Stacking

• Used Pattern Tool (Z-axis) to stack minar segments vertically (height adjusted to 4200 units).

• Tweaked vertical spacing with offset (−30) to avoid visible gaps.

---

🪜 7. Spiral Staircase Inside Minar

• Created spiral stairs (angle: 360°, inner radius: 110).

• Adjusted steps (width: 100, count: 18) to match each floor height.

• Repeated staircase across all floors manually using Alt + drag.

• Named and organized stair components (stairs_1 to stairs_11).

---

🔺 8. Adding Top Dome

• Copied dome from main structure.

• Scaled down to 0.15 and aligned on top of minar.

• Applied Bake Transform to apply scale/rotation cleanly.

---

📦 9. Merging and Duplicating Minars

• Grouped stairs and domes under minar_main.

• Copied and placed 4 minars at each corner of Gol Gumbaz using Alt + drag.

• Slightly repositioned each minar to avoid overlapping.

---

🖼️ 10. Adding Arch Pattern Design on Walls

• Reused arch patterns, applied Pattern (Linear) tool.

• Rotated and placed them along all four building sides.

• Final adjustments made to width (4750 units).

---

📸 11. Finalization

• Saved all.

• Instructed students to take a high-resolution screenshot of the final model.

• Mentioned next session will cover Voxel-based tools.
