The latest version of the popular Firestorm viewer for Second Life, released on October 1st, 2019, now supports Bakes on Mesh!
The Bakes on Mesh release from Firestorm has been long awaited; apologies for that. This should be considered by all in SL a MAJOR UPDATE, and it is important that all our SL users upgrade to it. This update contains a lot of rendering-related changes from Linden Lab, without which you WILL be running into avatars that look badly broken to you. Even if you don’t intend to use or purchase anything with BoM, you will still need to be able to see BoM items in your viewer. Please take the update. I can assure you we have put this through a rigorous QA process; it’s a great build!
You will need to get free Bakes on Mesh relay HUDs for the mesh heads and bodies you use. In my case, I picked up a Bakes on Mesh relay hud for Catwa heads from the Catwa store (at this exact SLURL), and a Bakes on Mesh relay HUD for the Maitreya Lara body on the SL Marketplace (here’s the listing).
If you want to get up to speed on how to use these HUDs, here are three videos by NovataSecondLife to help you get started:
The best part of Bakes on Mesh is that I am now able to wear old system skins that I thought I would never be able to use again with my mesh head and body! Here is a French court look, using an old Marie Antoinette-style powdered system skin from Xtreme Reality on my Maitreya Lara body and Catwa Kimberly head:


C’est parfait!
