Spoke to several people during after trying out several things they ended up pointing me over here. We started development on Intergalactic Road Warriors (http://intergalacticroadwarriors.com) back in november and started using the 2D Tools Preview Alpha 4, where the smartsprites were originally planned to release in march which was the month we wanted to launch our early access version. To be clear: we only use the smartsprites for the racetracks as you can see here: Then they got pushed back to june and eventually into 'in development'. We did have to release the game on early access with an alpha version of unity because financial reasons and there was no way to easily replace it with another asset. Talked to @peteorstrike at Unite Europe and they told me a new preview version was out finally! But... no smartsprites..., I just read that they probably won't come back until at least 3-4 months in a new preview release. So we're currently kind of in limbo, we want to move to consoles as well but the 2d preview alpha 4 of course does not exist for xbox one etc. @RichardFine and @Lucas Meijer suggested to see if I could look up the smartsprite source and copy paste from there to be able to move to a new unity version. Unfortunately it has been written in c++ so all the classes start pointing to InternalWrapperCalls or something like that. Another suggestion was to use the old editor just for managing the smartsprites and try to bake/save the mesh that comes from it for use in a newer version. Again, unfortunately there's no access at all to the generated mesh. Is it possible to get access to that old source? It seems a little to complicated and time consuming to just write it again myself. Any ideas?
