Stars including Craig David, Rudimental, Ms Dynamite and Stooshe graced the red carpet before entering the event.
Hosted by BBC 1Xtra's Trevor Nelson and Sarah-Jane Crawford, the ceremony kicked off in Scotland's newest and largest indoor entertainment venue The Hydro and is set to feature performances by Naughty Boy, Iggy Azalea, So Solid Crew and Tinie Tempah.
Jessie J, Jessie Ware and Rita Ora all return to challenge for the Best Female title and while last year's winner Emeli Sande is not a contender there could be stiff competition from Laura Mvula who has been nominated in four categories; best female, Best RnB / Soul act, Best Album and Best Video.
Battling it out for the Best Male gong this year is Disclosure, Rudimental, Wiley, Wretch 32 and Naughty Boy.
Laura Mvula shares the greatest number of nominations with Wiley who has been shortlisted for Best Male, Best UK Hip Hop / Grime act, Best Song for Reloaded and will come head-to-head with Mvula in the Best Album category.
AlunaGeorge will take to the stage with their song Attracting Flies, the track which has landed the electro pop duo on the Mobo short list for Best Video.
There will also be a "hotly anticipated" performance of the Cloud 9 collaboration between Ms Dynamite and Shy FX which will be accompanied by a sea of carnival dancers, organisers have said.
Kanya King, Mobo Awards founder and CEO, said, "We're thrilled at this year's diverse line-up and the additional two, exciting and unique performances. Mobo is all about diversity and this is the perfect mix of long-standing and new UK talent paving the way forward for UK music."
This is the third time the Mobo Awards have taken place in Glasgow and the first time at the £125 million Hyrdo which opened with a series of Rod Stewart gigs less than a month ago.
The arena has a capacity of 13,000 and will welcome around 140 events a year including sports fixtures during the Glasgow 2014 Commonwealth Games.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers.

We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
