My first post here and my first render tests with Corona.
I really enjoy this render! Lighting and materials are outstanding. My best regards to developer! You`re the man! )
I did some renders on different subjects to see how it works on differents scenes.
Jungle scene - 1500x845 wide, 2.3 h of render time on i7 (2.6 Gh)
Some berry closeup - 2K render took about 3 hours.
Interior scene. I tried to do day/night shots. Day shot 2K size took 2.5 hours. Night shot 1500x958 took about 4 hours.
In addition i tried to render small jungle animation. 10 min per frame limitation. I tried to render 30 min per frame, but terrible noise is still there and even if you put 1 hour it didn`t kill all the noise. And this is just 1K size.
My small hamble conclusion.
I didnt manage to get clean noise free animation with Corona. So in my opinion its not suitable for production animation so far (unless you have 10000 machines in renderfarm)). I can`t imagine how long will take noise-free render of my jungles in 2K.
For still images Corona works the best! But if you have some low lit scene like night shots, it will take a lot more time to get rid of the noise. My night kitchen shot took 4 hours! and take a look at amount of noise and some bad AA stepping around hot areas of light sources.
Again, this is my first tests, all done by default settings. Maybe there is a way to avoid all those problems, will gladly learn them, if you have some advices!
Thanks a lot! Here is the banana palm material. I use texture in transl slot here, but for most of the leaves i just use green color without any maps. Other settings are similar.
Another corona test. 3 hours of render. PT-32, MSI - 30, SM - 4
Still have some noise, can`t get totaly clear image so far. I tried lower MSI and SM, but noise is still there. Not sure what i do wrong ((
Here another test. Looks like Corona Z map is not fully correct in my opinion (like Vray Z as well), like it has premulted edges, if i`m not mistaken. I did DOF in Nuke using Corona Z and default 3DMax Z map. Edges are pretty different in quality, as you see.
Well, i call it “default”, but maybe its not )) when you save your render in EXR, you can add Z Depth in G-Buffer channels in popup dialog. Unfortunately you cant put distance there, 3dMax take into account all the objects in scene and create depth on it`s own. Bu it unpremultiplied so the edges looks more clean on post.
It got nothing to do with Photoshop, guys. Well, i dont see why you have problems saving EXR from corona. My only guess is you save it in 2.2 gamma, thats why you get “over-brighten” white images. Save EXR only in gamma 1. I hope it will help you ))
