I am currently modelling an Optare Solo M880 for OMSI 2! You can follow all updates here: https://fellowsfilm.co.uk/threads/optare-solo-8-8m-m880-slimline.5074/page-2#post-69404 but I will sometimes post larger updates here. I am using Google Sketchup to develop this, I know most people disagree with this, but I feel that it is a good software for beginners such as myself.
Here are some of the FAQ's taken from Fellowsfilm Network:
FAQ’s:
Q: What Variant are you releasing?
A: For now, the M880, I will be starting a M850 soon!
Q: What length(s) are you releasing?
A: For now, I am only creating the M880, but I may release others depending on the buses success.
Q: Why use Google Sketchup?
A: I’m using this program as I believe it is good for people like me who are new to the world of bus development, I know a lot of people and possibly even me have moaned at developers for using this program but I don’t really mind what others think.
Q: Will you be showing us from time to time the bus in Blender?
A: I may if people would like that. I would just need to learn more on how to do this.
Q: Can I be a Beta Tester?
A: Absolutely… NOT. I will be picking out a team of trusted people when I feel this bus is ready for Beta Release, and currently it is nowhere near.
Q: When is the Planned Release?
A: Currently, even I am unaware of this at the minute, I will be able to confirm a date closer to release (Which will be about two weeks prior to the release.)
Q: Can I become a member of the development team?
A: At the moment, no. If I feel I need help within the project, I will privately ask an experienced member for help.
