Well, I am going to try Vue. My scenes are getting more and more complex and large, and I am getting so frustrated with Firefly choking on renders. My book illustrations are 2400 by 3000 pixels, and in almost every scene I have the problem in Firefly rendering almost all of the scene and then sticking at one point making no further progress for days on end. It doesn't seem to matter whether I render to the queue, in the background or directly in the Poser application. I have resorted to terminating the render, saving it out and than pasting area renders of the trouble spots on top of it, but this is getting tedious too. One would think the problems would occur on hair, plants with transparency or some other thing with known difficulty, but that is not what I am finding. I am left with mysterious buckets on plain flat surfaces without complicated shaders, that fail to render. I am at the end of my tether with these Firefly rendering problems.
