Cannot Paint Tri-Mesh

Hi Yes I experienced the same thing - if you use primitives and not trimesh objects you can paint them just fine. I had a discovery today regarding trimesh that has left me very frustrated, I had brought in some assets from the assets library, trees, tent,  and some smaller objects, after spending two weeks building my world, went to hit publish and got a message saying unable to publish as world had pre-release assets. After some searching online, I think that the issue is when you start with a primitive world you can’t add trimesh and vice versa. You can identify trimesh objects by looking at the info panel of the object in the top left corner if you see a simple cube symbol it is a primitive, if you see a more complex symbol it’s a trimesh. I am now having to recreate the trimesh assets as primitives - it is quite frustrating as it is not clear when importing asses from the assets library. The world works and looks fine in unpublished mode, just aren’t allowed to publish due to trimesh assets 🙄 It’s a learning experience and at least I have learnt stuff along the way. So for now I will just be using primitives to create assets myself and forego the trimesh more detailed objects until meta decide to allow them to be published! Good luck with it all!
