Blender and Unity HDRP

My question is why is it so complicated to model and texture in Blender and import into Unity?

It used to be ok...

But now with the Map File and Blender with it's 'I won't bake metal maps', and 'my glossy maps are rough'!.

After much research, the best you can find is an old tool in Github or resorting to some Photoshop wizardry.

Given that most young people cut their teeth on Blender now, why does Unity not create some tools to make importing textures easy?

stumped.

 

Turning a gloss map into a roughness map is as simple as inverting the channel. The fancy combined maps that HDRP uses aren't that complex either. It's just a matter of combining channels into a single image. While these things are technically possible in Blender i would suggest using a dedicated material program for this, such as Substance

As for your last question, Unity seems to have gone knees deep with Autodesk partnership, and blender is a competitor to Autodesk.
