I connected two File Pattern nodes (Low-poly and High-poly) to a Partition by Index node, but only the information from one File Pattern node is being displayed.

How can I output and view the data from both File Pattern nodes simultaneously?

This usually happens because Partition by Index is only effectively receiving/processing one stream of work items, even though you’ve visually connected two File Pattern nodes.

In most node-based PDG/TOP-style setups, each upstream branch is treated separately unless you explicitly merge them into a single stream.

What’s going wrong
Each File Pattern node generates its own set of work items
Partition by Index expects a single combined stream
Without combining, one input often ends up overriding or being prioritized in the display
How to fix it
1. Add a Merge node (most common fix)

Place a Merge node between your File Pattern nodes and Partition by Index:

File Pattern (Low-poly) ─┐
├── Merge ── Partition by Index
File Pattern (High-poly) ─┘

This forces both datasets into a single unified stream so Partition can actually see everything.

2. Verify display vs actual data

Sometimes only one branch shows in the viewer even though both exist:

Click the Merge node and inspect work items
Then check Partition output separately
3. Alternative (if you need strict separation)

If you actually want to keep them distinct:

Use two separate Partition nodes (one per File Pattern)
Or tag each stream first (attribute like source=low/high) and partition later
Key idea

Partition nodes don’t “visually combine inputs” — they operate on whatever single stream they receive, so you always need an explicit merge when working with multiple generators.
