Yes it is different, however Bricklink references are often added to part data.
Sometimes it is not or the element doesn't exist yet in the part library.

sorry for bothering you. MB is so much more convinient and easier to use. i just want to buy some of my MB projects so I copy the piece numbers and build it again on bricklink.

There's an option to export your build to a bricklink inventory. 😉

really? how? thats brilliant

When you publish the model, click "inventory" right under the model view. There's an option to download the bricklink xml which can be imported to get the part list on Bricklink.

Thanks!!! I will do that now

There is a new update of brick link. Maybe it will feature the parts I couldn’t find

The parts you are searching for will probably never be on Bricklink or in Stud.io because they are not special parts that have a printing but parts with a sticker in them.

6091pb010 is:
Part 6091 in Orange with a Sticker from 75912stk02

11477pb020L and 11477pb020R are:
Part 11477 in Orange again with Stickers from 75912stk02

Also, if you want to search parts by Bricklink item numbers, it might be useful to change the "Mecabricks/Bricklink" slider to "Bricklink", which works for most MB parts.
