Texture Painting

I don't know any Marvelous Designer, but sounds like there should be something when you export out of it that you need to set. Maybe you can post some screenshots of the before and after. What file type are you exporting and importing in Blender? Try to give us more details.

I'm also not familiar with Marvelous Designer, I agree with Omar, it is most likely an export setting that needs to change to use it in Blender.
If you can post a screenshot of the export settings we may spot something that is wrong.

Possible things that have to be ironed out, it's always like that with big releases and not just in Blender. 

Hi Yisrah,

You should be able to find any Blender Version you want here:

Hi Yisrah,

It indeed depends on what textures you need.

Maybe you can also try Textures.com...

And for more suggestions, you can have at look at the Fundamentals of Texturing Lesson:

Or the new trend, to have AI make whatever texture you want. Although there seems to be people that get angry when you use AI, but I guess pay no mind, get the most out of such a new tool if you can.

You didn't hear it from me.

Hi Yisrah, I have no idea what Pipelines you are talking about, but if it's an Addon, you might wanna search for it in Get Extensions (just above Addons in your Preferences).

JL explains the new Extensions in this video:
