Blender dimension

The official parenthetical is short: "F - Blender Dimension (Press before entering a portal)". Stand at the portal, press F, then walk in. Reversing those two actions is not described, so this page does not promise a late press still works.

  1. Equip the portal gun with T and place a pair, the same way you would for a normal hop.
  2. Before either foot crosses, press F. That is the whole selection step.
  3. Walk through. What you should see next is not in any source used here.

What stays unknown

portalsandboxwiki.wiki writes that map layout, loot tables, and dimension-specific rewards stay TBA. I treat that as an admission, not as a hint to fill. No pass sells "blender access". No video caption on file describes the room. If you came here for a reward table, the honest table is one row: unknown, unknown, unknown.

The wider R menu is a different control. R lists Dimensions. F picks this one destination on the way through a portal you already placed. Mixing them is how people miss the door. The dimensions page explains why a count of worlds is still blank. Keys for the rest of the keyboard are on controls.

Questions

Is this Blender, the 3D program?

No. The name is an in-game destination. Searching the software will bury the Roblox key.

Does T send me there?

T equips the portal gun. F is a separate choice you make before stepping through. The gun alone is not the blender door.

What is inside?

Not published. No reward, map, or fail state has a source.
