I have encountered this weird problem.
I have an installation that has 3 projections run from one computer. each projection is running in its own instance and it running fine... for a little while, after some hours, all renderers goes black. I can't see a pattern to what is causing this.
it's 3 times DX11 patches And one patch controlling stuff (some DMX, Projectors and some UDP) all is running from a bat-file being run as custom user interface, so very little else is running.
Any idea why this is happening? what to do?
