Everything shall import. Please give us more information about your process and what you use. Which Mecabricks Blender add on?

I use a mac, blender 2.82, and blender light add on. I found the files, but their not showing up. it says they don't have any design on the minfigures. i import and put on render view, and its not showing up. Im new to blender, so i dont know all the short cuts and stuff.

I found the textures in the texture paint area, but i don't know how to add the designs on them.

You don't need to do anything. If you import the zmbx file properly it is all done automatically. Make sure that you use Cycles and not Eevee.
If you are still in trouble, please post screenshots here.

you totally saved me!!! thank you so much!!

Okay so let me get this straight. The textures only show up on the render?

Yes, this is how Blender works.

Oh okay. Thanks Scrubs! (^_^)

You guys saved me. Thank you

I'm still having the problem even after switching to cycles

Blender opens in the Solid viewport shading mode. Did you switch it to Material Preview or Rendered?

I know that but when I do that the textures arn't loaded on the UV's are wrong and some of them are purple

Ok, good... here's a few more questions:

Which version of Blender are you running?
Which render engine are you using? (cycles, right?)
Are you seeing purple bricks in both Material Preview and Rendered viewport modes?
What model are you exporting? Is it public or can it be made public?
Which part numbers are having issues?

Finally... can you post a screenshot?

i restarted blender after switching to cycles and its working thankyou for your help

when i import a lego figure many of the textures are missing and it is just pink why?

Blender lite was designed for the Cycles render engine and is not 100% compatible with Eevee. Pink coloring in Blender generally means you're doing something that it doesn't like. Often times it's a missing/broken link to an image, but it can also happen if you have a node setup that's not compatible with your chosen render engine. You can sometimes get away with using Blender Lite with Eevee, and sometimes work around it by modifying the materials.

If you switch your render engine from Eevee to Cycles, that should fix your pink parts problem.

I onely work in blender using Cycles and it still not work. It work fine for like importing normal models but when im trying to import a figure the texture dont show up why?

Can you share a screenshot of your entire Blender screen?

IDK how to do its but when im uploading in blender 3.0 it dont work?
