KeyShot and Octane were the engines taking best advantage of my RTX 3090 GPU. A lot of my work involves complex optics (lenses, half-phase and band-pass optics etc) using very specific materials, something KeyShot manages excellently. My CAD tools of choice are Inventor and OnShape, but clients sometimes provide parts or props in 3DS Max, Maya, STL, and a dozen other formats. KeyShot handles practically any CAD or 3D model format I can throw at it. KeyShot was simply the quickest to set up for excellent results that made my clients happy. For me, scene setup time saved is worth more than hardware cost or rendering time saved. I read that Blender is not really optimized for architectural renders, but I am not sure if that just means it can do lots more many of us don’t need, or whether it means it is much harder to get a result than with other more focused software.My situation mirrors yours: I am a freelance industrial engineer and also provide photorealistic renders when required - and I paid for KeyShot from my own pocket.Īfter evaluating several rendering options, including all that you mentioned, I selected KeyShot for these reasons: If you want to go further, it’s nice to be able to add artificial light sources. You may just need to be able to import backgrounds, adjust sun and shade settings, camera position, and not much else. It will often be external views which means you can rely on a single light source, the sun.īlender has a whole host of tools that aren’t necessary for this limited task. I don’t suppose I am alone in mainly wanting something that will take an already impressive SU 3D rendered model and jazzing it up with more realistic lighting, without having too steep a learning curve or having to spend hours just to get a slightly better render. 
There’s been a lot of discussion about using Blender as an alternative to SU but I’m not up for that.
It’s hard to know how many people are using Blender this way, even if only as a cost-free gateway drug to “proper” render engines. I have been looking into the capabilities of Blender for use as a photorealistic renderer for SU models.
