World Panel Overview

Materialiq contains 31 HDRs from Greg Zaal. All of them have 4k resolutions to save memory and shorten time spent loading them for rendering. These HDRs were named according to perceived time of day for convenience.

The materialiq world panel is located in the World Properties tab in the Properties window. All features related to HDRs (worlds) can be found there. Please look at the material panel page for spawning materials or accessing material-related features.

Info

Materialiq is the only polygoniq addon that is located in the Properties window. All other addons can be found in N panel on the right side of the 3D viewport window.

Summon Selected

Summons selected world into your scene. Currently selected world is the miniature preview shown on the left side from the button. You can select different world by clicking on that preview image.

Summon All

Summons all worlds from materialiq. This allows you to quickly swap them, see different lightings quickly and decide which world suits your scene best. Note it needs a significant amount of the memory, so working with it can be slow.

Exposure & contrast

You might have to set the exposure higher with dark HDRs and lower with bright HDRs. Also sunny HDRs might work better with lower contrasts and overcast HDRs with higher contrasts.

Remove Duplicate Worlds

Removes all duplicate worlds that have suffix .001, .002, ... These duplicate worlds will be removed only if there exist world with the same name just without duplicate suffix. This world without suffix will be used on all places where original world with duplicate suffix was used.

Rotation

Sometimes sun does not really hit the geometry well and the render comes out rather dark. This might be the intention but it is good to know that HDRs can be easily rotated.

In this case we can make sun to shine inside the room by rotating HDR along the Z axis.

Post-production background

Since the HDRs are 4k it might be good to swap them in post-production to prevent blurry appearance. 4096 pixels wide HDRs give you only 11 pixels per degree.

To make this easier, you can set the film to be transparent and save renders in RGBA png or other formats supporting transparency.
