foxb612 a écrit'm using a project from github based on the c# runtime, which can do the rendering in winform applications. So I need to dig into that part instead of spine runtime for this option.
Another option is to just use straight alpha: when you export your texture atlas, you don't have to check the PMA option.
foxb612 a écritI have to use 3.5.51 to match the source file version... it's a bit inconvenient that runtimes of new versions aren't compatible with old files.
True, it is a little inconvenient. FWIW, it's done that way so that the runtimes don't get bloated by needing to load data from all older versions. To use 3.8 I guess you'd need to update the winforms runtime to 3.8, which may be pretty easy.
