Iso Scene To Surface

Overview

Converts an IsoScene into a Surface with face information. This lets blocks and extrusions built by the existing isometric generators use surface lighting.

Normally, connect the surface output directly to Surface Light Preview. The top, left, and right faces of each block have separate face IDs and normals, so changing the light direction changes the brightness of each face.

The geometry output is a secondary output for passing the original isometric face data to advanced processing. You can ignore it in normal workflows.

Usage tips

• This bridges isometric scenes and lighting. Route the scene here instead of through the simple iso_scene_render to use all Surface lighting, face-ID, and material-processing features.
• Top, left, and right faces have separate face IDs and normals, so surface_light_preview responds to the light direction per face.
• Use surface_id_mask to extract part masks such as "left faces only."
• Surface rasterization is limited to 4096x4096 and an estimated aggregate allocation of 768 MiB. Oversized or invalid face data is rejected before output allocation.

Example

Iso Block → Iso Place → Iso World To Scene → Iso Scene To Surface → Surface Light Preview

This displays a Surface whose block top, left, and right faces each have separate face IDs and normals.
