Sorry that you're having issues with rendering in 3D. The primary reason it is taking a long time to render is that there seems to be transparency on top of it being an anaglyphic 3d letter. But even if it was one or the other by itself it would take more time than just a solid simple color. And yes, that's just not as cool... I see Pete Green, is on this thread is collecting more information so that we can look more closely at the problem. And as far as playing Devil's Advocate... sure Photoshop 3D is not perfect but it is a great way to learn from a familiar setting. I would agree that if you want to more into 3D designing then finding an application like, Adobe Dimension or even Cinema 4D would be better in the long term. In fact, if you have subscription Adobe Dmension is a free download. You can export your Photoshop 3D letters as OBJ files and render them in Adobe Dimension. However, even using those applications you're subject to what your computer hardware can provide. You might seems some speed ups here and there but as a 3D scene gets more complex (e.g. Materials, Lights) render times can slow to a crawl. Also keep in mind that when rendering you don't have to wait for it to "finish." I find more often than not that I will cancel the render before it's done because it's good enough. And of course document size can have an effect as well, what is the maximum size you need? Tips: And to parrot Davescm > Most of the render time will have been taken up rendering empty space when all you needed was the individual letters. Also if you don't need an IBL (Image Based Light) turn it off. I can't tell if you have one or not or are using one. It will add all the soft shadows that take extra time to render. And then selecting only the letter becomes a super time saving trick. Hope this helps!
