Save to say, it’s one of the most advanced GPU engines powered by CUDA capable devices.
Unlike any of mentioned software Octane Render isn’t hybrid engine (running on CPU & GPUs), nor does it run on CPUs at all, at least for now, as recently in GTC 2015 unveiled version 3 will run on more devices & have more impressive feature list. much like Vray RT for GPU, ARION Render, Iray, etc. I have never used vignetting in corona for this reason, but now I'll probably use it much more often, as I did with vray.įor those who don’t know, Octane Render is an unbiased GPU powered rendering engine. This now means that really bright areas (sky) will not look artificially dark when you add vignetting. A quick Note on vignetting in Corona: Vignetting in 1.6 finally works as (I believe) it should, in that it doesnt just add what looks like a black overlay, it correctly reduces the exposure at the corners. I'm going to finish with a slightly re-worked version of this scene, made entirely in Corona with no post work at all. For some reason its much easier to get nice results with Corona and you can also tweak them as it is rendering. Another thing Corona does very well is lens effects (bloom and glare). I never got on very well with VrayRT, partly because it required more set-up and because it wasn't the same as a final render.
If you haven't tried it you really should. The joy of working with Corona is in using Interactive rendering to explore new compositions, tweak materials, play with lighting etc. Matching vray2sidedmtl with Corona is always a bit hit and miss, I use interactive and tweak till it looks similar.In Corona, you just apply coronafogmtl straight to geometry, no need for a gizmo.(Corona 3d displacement has improved a lot but I still miss Vray 2d displacement.) You will need to play with the corona settings to try to match it, especially if you used vray 2d displacement. Corona's displacement is inferior to Vray's.I use vrayhdri and vraycameras, there still aren't equivalents in Corona.There is no need for a dome light (plug vrayhdri straight into environment) so remember to take into account any multiplier on the domelight.The vrayhdri map works well in Corona but remember the render multiplier doesn't do anything so adjust your overall multiplier accordingly.Vray cameras work fine in Corona, but you might need a coronacameramod to fine tune DOF.Converting a Vray scene to Corona is pretty much a one-click process thanks to the amazing conversion script that comes with corona (I should add that the conversion back to Vray using the script that comes with Vray is also very good should you need to go that way.) Some things to remember though:
