Shops Gen (HDA + Unreal Interior Mapping Shader)

Shops Generator is a Houdini Digital Asset paired with an Unreal interior mapping shader, built for filling shop-heavy environments quickly. Draw a curve, and the asset generates a row of shopfronts along it. The shader fakes the interior behind each window, so the storefronts read as real shops with depth rather than flat facades.

Materials are distributed randomly across the shops from a pool you define. Add as many materials as you want, weight each one so some appear more often than others, and change the seed to reshuffle the whole street without touching the setup. A block of shops that reads as varied comes out of a few parameters rather than manual placement. The asset also generates plain pillars and walls, so the same tool covers the structural pieces between and around the shopfronts.

Limitations: ⚠️ Please read before purchase⚠️

- This asset is built for Unreal specifically. Outside the Unreal ecosystem, without the interior mapping shader, the output is a plain facade with no interior depth.

- The curve must be kept straight. A straight run rotated as a whole works correctly, but a corner partway along the curve distorts the interiors, and the distortion grows with the angle. To turn a corner, place a separate instance for each straight section.

What it includes:

- The Shops Generator HDA

- Unreal project has the main elements (The HDA, Interior Mapping Shader Edited and Compatible With the HDA, and an Example Cubemap Scene)
