Texture alpha. Bug or strange treatment by editor
I'm trying to boost performance of out game. One of steps is to create atlases. The oryginal material had two textures. One for Base Color, and the second for Roughness. Both compress as Default.
I decide to pack Roughness as Alpha channel in atlas. This is where problem start. In texture preview old texture and new (alpha) are nearly identical (compression probably), but in material alpha is more then 10x brighter!! On screenshot below I used multiply by 1 node for preview window. The texture of intrest is the one in the middle of bottom line on the altas.
Here are the textures to download https://we.tl/tTIQQU6jq5
What is going on. Is it a bug, or a way how editor treat alphas in material editor?!
