Hi,
my first project done with Corona.
Sorry, the room is not so “cool” 
. But it was just a test to understand how Corona works.
It was an old scene modeled and textured from my friend with VRay.
I just convert from VRay to Corona, change the bed, the pillows and add the blu carpet.
Super!!!
hi cecofuli
very nice render 
render time?
() 9 hours for the first at 6000px (during the night)
() 4 hours at 2500 px. But after one hours and half was ok. But the DOF is not very clean.. Look the last picture, on the right side.
I have my machine free, so I run as much as I can.
Usually, in VRay I render 3 hour for these renders.
All resize at 1920px. No noise reduction. Some little post.
ok thanks
Why do you say it’s not cool? I think it’s AWESOME! Everything is perfect - models, textures, materials, lighting. Only one thing bothers me - how do you open the wardrobe that is touching the desk/bed? Also, can you even seat by this desk or is it some crazy moving machine?
I don’t know. the 3d model is not mine It comes from the company.
Here some WIP.
() MSI looks like a VRay GI caustic. So, with high MSI we can see the caustics generated by GI (not caustics from glass)
() MSI is a “threshold” and VRay GI caustic is only ON or OFF.
() MSI high = more GI caustic = more noise but better quality.
() MSI 00 = a lot of firefly
You are right. But it also affects glass caustics. Basically it’s pretty much what it says - maximum allowed sample intensity.
btw, just visited your website and I’m speechless.
Thank you I would like to use Corona for some exterior project.
But I’m a little bit worried cause Corona VFB eats a lot of RAM. And my exterior are very complex (I use a lot Multiscatter)
Don’t worry about the multiscatter part, Corona can render instances fast and efficiently (with low memory usage) 
Hi Cecofuli, nice images you have posted here
Also…i bought your book years ago!
I know, but in my test, if I lunch a 5000 px render, Corona uses, just for VFB, 4-5 GB of RAM!
For this scene, Corona eats 14 GB RAM. Too much in my opinion.
I don’t know what happen with a scene like this
But, I have to try
yes, I know I’ll have to rework VFB in the future… probably with reintroduction of (progressive) bucket rendering and better contrast function/some tonemapping curves. But for now I’m doing more urgent features like IES and DR
I agree 100% with you! DR and IES are a priority.
btw by setting internal res. to 1 you’ll cut the memory usage to 25%, but you won’t get antialiased highlights…
Maybe for my heavy external project, highlights are not so important Good to know.
Ok, I’ll try in my next project
Caustic in vray very approximated because it is calculated by LightCache. Here are a few different algorithm, which allows you to get a much better caustic and even from light sources.
