What is the difference between Quibli and Flat Kit?

Please, look at this chapter, which compares the two.

After installing Quibli there are some issues.

Please, look into the Troubleshooting section.

The scenes in Unity look darker/brighter than the screenshots.

The screenshots on the Asset Store are taken from the scenes, without any processing or color correction whatsoever, i.e. they should look virtually the same as the scenes, minus the embedded description text. The differences may occur if your project is in Gamma color space, as the scenes were made in Linear color space. Another reason may be in the unfinished setup (how to finalize Quibli setup?), when the scene can’t find the needed forward renderer.

Which Rendering Pipelines does Quibli support?

Quibli supports Universal (URP, fka LWRP) only. It won’t work in Built-In RP and HDRP.

What is the Shader Compilation Target Level of Flat Kit shaders?

The object shaders target 3.5 (or es 3.0 and WebGL 2.0).

I’m getting errors after moving the Quibli folder from Assets.

This is due to a bug in Shader Graph which has been fixed in URP 12 (Unity 2021.2). To work-around the issue in earlier versions of URP, please click the “Reimport Quibli files” button in the Readme file after you’ve moved the Quibli folder.

How do I get 50% discount for Quibli if I have (am going to purchase) Flat Kit?

Please, log into the same account with which you purchased Flat Kit, open the Quibli’s Asset Store page — you should see the automatically applied 50% discount there.
