Optimising Textures

In order to optimise and improve the quality of our project, it was essential that I went back into our Substance Painter files and our asset model file in Maya, and ultimately optimised them.

 Until this point, we hadn't moved our assets UVs into one map, and instead, were using multiple maps.  DISASTER.

ANYWAY, we are fixing it.  Moving all UVs of each model into one map means that when applying textured and exporting them to input into Unity, there will be much less clutter and texture overlap.

 At this stage, this will help in a huge way for us as currently, the way we exported and imported, we had thousands...and thousands....AND THOUSANDS of textures in the unity scene.  Each asset could have had as much as 40 textures on it.  UNBELIEVABLE AND IN NEED OF FIXING.

 So here we are, going in, moving all UVs (after being correctly unfolded and laid out in Maya) and exporting them into Substance.  From here, it's about reapplying the textures from before and developing them further and then exporting as one UV map instead of several.  This would mean that each asset could have a maximum of 6 textures and 7 id opacity featured in the texture.  This has cut our texture list in unity from about 27,000, to 197.  A big and much needed change.



This is one of many ways we hope to optimise the scene.  Next up is to delete unneeded faces and parts our scene that the user will never see.  After this, it will be to import image planes to replace certain 3D models that are not engaged with or that do not change form throughout the narrative.  These changes will be described in depth in future posts.

CV and Business Card

Before heading into the big bad world of employment and potential freelance work, it is essential we leaving Undergraduate level with a professional portfolio of components we can use to sell our skills and help put us on the industry map to propel us towards a future career. This is in regards to two main pieces of self promotion.  The CV and business card.  It is important we have these designed, printed and accessible on the night of our end of year show so that company reps, directors and other industry members can view our projects and then take something tangible away from it to remember who we are and what we are capable of. When it comes to CV, I have always been taught through my years of business orientated education that it is simple, clean and not overly creative.  I was always taught that colour is tacky, images are resented and icons are acceptable but need to remain minimal.  When I approached this initial design stage of an updated and a...

Personal Reflection - Final Year

As the time to submit our project approaches faster than ever, it feels right to look back yea, at the last several months, yes over the last year of Uni, but also, over the last four years I have spent at Ulster University.  This year was a year of superior unsurity, yet a feeling of excitement and wonder about what the FInal Year journey would be like.  Being in the team I find myself in, was an amazing thing for me.  Never in my four years as an Ulster University  student, have I had more confidence in the ability and determination of a group of people to achieve a task wholeheartedly and true.  Lorna, Cassie and Megan?  You guys were the best team I could ask for in my Final Year of University *sniffle sniffle bleh* Taking on a virtual reality project brought with it many challenges both personally for myself and for us as a team.  For myself, I found the technicalities and new software hard to adapt to.  Having been out of the animation...

EOYS Finalising

As the End of Year Show grows closer, a lot of effort and thought have gone into promoting it, sending out invitations and getting things ready for the big night on the 7th June, 2019!  A huge hats off has to go to the amazing committee that have worked so hard to facilitate and make the night happen.  With their fundraising, planning and design, our End of Year Show, is sure to be a huge success and great celebration of all of our hard work! Personally, I have enjoyed helping out with my classmates preparing the rooms for the night.  Painting, moving and rearranging the rooms so that each team/personal project has a good place to showcase their amazing achievements.
