Portal Sandbox Portals: Gun, Blender and Fixes
Portal Sandbox portals have three different questions: selecting the Portal Gun, choosing Blender before entry, and diagnosing a failed action. Pick the one that matches the point where you are stuck instead of changing every input or assuming a paid variant repairs travel.
Before-entry conditionBlender uses F before crossing; T selects the Portal Gun.

Open the answer that matches the task or obstacle in front of you.
I need the Portal Gun controls
Select T, distinguish the Laser Pistol input and read what the named gun passes advertise. The guide keeps those choices separate from a promised performance ranking.
Use the gunI want Blender Dimension
Make the Blender choice before crossing. This guide concentrates on the F-before-entry order and correcting a mistimed attempt, rather than a made-up destination walkthrough.
Follow the orderMy portal action is failing
Separate a missing selection from a Blender-order issue, make one calm retry and describe the repeated symptom. Start here when the normal action is the obstacle.

Guide
Portal Gun Not Working
Separate a missing tool response from a travel problem or a mistimed Blender choice.
Separate the tool, the entry choice and the symptom
T names the Portal Gun, while Blender Dimension has its own F-before-entry condition. The gun article keeps selection and the advertised optional variants together; the Blender article applies the extra order without inventing a destination reward or damage rule. Troubleshooting starts by distinguishing the wrong tool, no response and an unexpected travel result. That distinction makes the next check useful. A new gun name or UI color is a purchase topic, not proof of a travel advantage. After the relevant action is familiar, move to the next activity rather than repeating every portal guide.
Questions about portals
Is T the Blender input?
T selects Portal Gun. Blender Dimension uses F before entering a portal. Keep those two jobs distinct so a correct tool selection does not get mistaken for a completed Blender sequence.
Should I buy a variant to fix a portal problem?
Treat the optional variants according to their advertised items. Do the input and entry-order checks first; a product name does not establish that it repairs a missing response or changes the travel rule.
Add a deliberate combat plan
Once travel selection is familiar, choose a weapon and remember regeneration before an encounter becomes hectic.
