Not really a daily build feature, since Corona 10 is already released, but we didn't have a dedicated playground thread for this, and we are super curious about your results, so here it is!

If you are rendering a scene where highlights are blurred due to depth of field (distant city lights, interior lighting, reflective/refractive objects), you can enable the new DOF Highlights Solver to get faster rendering.

You will find the checkbox in Render Settings > Corona > Performance settings. You don't have to change the Budget and Reprojection values as the defaults work well (but you are welcome to test them if you wish!).


You also need a camera with depth of field enabled.

Example 1 - Same render time - Click to open interactive comparison




Example 2 -Same render time - Click to open interactive comparison




You can learn more about the new Highlights Solver and DOF in general at:
- Corona Help Center
- Corona Documentation

Sorry, but I am not sure what is going on there. Could you please attach a sample scene here or at https://support.chaos.com/hc/en-us/requests/new

hello here a test scene,
it seems to be related to bloom & glare, a refractive material and or a self illuminated material, test the scene once without and with the highlight solver and leave both rendering bllom and glare on

Hi there, are you using the viewport IR for this? Does it happen if you run a default or final render?

Took it for a spin and here are my thoughts, if you wish to consider.

It's extremely slow feature (compute heavy) still leaving some noise. Takes extra attention (observation & knowledge, thinking about solution, settings...) so in cases alike I prefer Intel's OIDN to solve such issues in final render (or to composite in post), thus I'd rather see updated OIDN to last version ;)

But, may this feature become standard part of Corona, I'd prefer to see and set it in Camera (tag) under DOF.
Finally, I wonder (rhetorically), is development of such perks worth it, since there's so many other stuff to fix and make better, faster, more convenient...
... What happened with "effortless UX" principle.

Anyways, have a good weekend.

i wonder, in vray dof seems to have almost no slowdown compared to no dof,
in corona it makes the render quite a lot slower. also with this new feature.

now corona seems faster overall than vray, but still i also hoped this would come more in direction as vray solved dof. without any headache.

i know it is yet marked "experimenal", so i hope this gets faster and more polished in final version.
