Unapplied compression settings for Texture on macOS Silicon

Unity Engine
,
1

Hello,

We’ve noticed our build time for macOS is +4000 seconds more than windows and linux.

After some troubleshooting we were able to find a difference between the two.

PNG textures imported on Windows or Linux with Mitchell, Automatic Format and Normal Quality compression, will display:

RGBA Compressed DXT5 | BC3 UNorm

whereas macOS will display:

RGBA UNorm

Changing the options in the dropdowns does nothing.

We are using Unity Editor for Silicon with AutoGraphics (Metal), version 2021.3.9f1

This seems to be causing a size difference. The windows one is 256Kb while the mac one is 1Mb for the same PNG file.

We suspect this might be the case for our extended build time on mac.

Thanks very much for your help in advance.
Mauricio

Hi there,

After a short talk with the texture team they think it could be a bug, could you report the issue from the macos that fail to select the correct compression and report the bug number here? We’ll have a look as soon as possible.

Thanks!
