Question 1

What are Visual Filters in Physion?

Accepted Answer

Visual Filters are GPU effects that a Node can wear: a glow, a drop shadow, a blur, pixelation, CRT scanlines, a shockwave, and 29 more. They change how the Node is drawn and nothing else. Its shape, mass and collisions are exactly what they were before, so a glowing ball bounces the same as a plain one.

Question 2

How do I add a visual filter to a Node?

Accepted Answer

Select the Node, find Visual Filters in the Property Editor and click Edit. The popover lists every filter in five groups. Flip the switch in a filter's header to turn it on, expand it to adjust its options, and the scene updates as you go.

Question 3

Can I apply a filter to the whole scene?

Accepted Answer

Yes. The Scene is a Node too, so it has the same Visual Filters property. A filter on the Scene is drawn over everything in it, and a filter on any Node also covers the Node's children, so a group of bodies can share one effect.

Question 4

Do visual filters affect the physics?

Accepted Answer

No. Filters change how things look, not how they behave. A shockwave that visibly bends a box does not move it, and a blur does not soften a collision. Physics runs exactly the same whether the filters are on or off.

Question 5

Do the filters animate?

Accepted Answer

Seven of them do: God Rays, Reflection, CRT and Shockwave drift and shift over time, and Glitch, Noise and Old Film reshuffle their grain every step. They move while the scene is playing and hold still while it is stopped, and each one has a control to freeze it.
