I´m vray user since i started in 3d-visualisation years ago, so i collected a huge library of models and materials - a main reason, why i´ve never worked with other renderers seriously (also unibiased is too slow for my workflow).
Now, it looks like i´ve found a new baby i can play with - the vray-materials converter is damn great and one of the most important tools for me to keep hands on an alternative render to vray if i wanna make really realistic images!
Also the Backgroundimage-material is very helpful and easy to use!
So i´ve tested corona a few days, here you can see my first test-scene…it looked pretty good after 90 minutes. Finally i wanted to stop rendering, when the darker area in the kitchen on the left is clean enough…Resolution is 1600/928…other information you can see in the picture (corona stamp). CPU ist overlocked to 3,8MHz.
All materials are vray-materials converted with corona-converter-tool. Only played a little with opacity of curtains etc…
I´ve done a quick postwork very slightly. Maybe it doens´t look too realistic as i´ve only a cheap monitor…
Render settings are default (except: Precomp Step of HD-cache is “2”).
As i´m new to unibiased, i´m not sure if the value “ray/s” (bottom right corner) is an indicator to speed of rendering?
Very nice setups! I like the look and feel of your images
Since I’m always trying to make the converter better: are there any wishes or suggestions for Vray conversion? MR conversion is pretty much 1:1 already but Vray materials are a bit harder to do
Nice modern interiors. I think something is wrong with lightness-darkness ratio, though. For example in last render I think background should be much brighter, at least for a photorealistic look. But I may be wrong.
@DeadClown: I noticed that the vraynormal map obviously is not translated, but it bring to crash when trying to render. I suggest to disable the corona bump map slot after the conversion when there’s a vraynormal map in the vray bump map slot, with a warning message with the list of which materials have normals assigned. I had a model with lot of objects and the task to find which object was causing problem was a long and tedious work. I suggest this until corona support normals, if the next release of alpha/beta have normals support and soon to be released discard this. Just my experience. Bye!
Rawalanche: That would be awesome
andreupuig: oh.. yes, I forgot this one. I added a warning for the max normalBump map but not for the Vray one, I will add it asap
I like the pictures exactly because they don’t have the sterile photograhic look
Rays/s is the indicator of the crude, brute-force rendering speed. It is higher on better CPUs and in simpler scenes (simple shaders and geometry, only path tracing with no caching), but it does not indicate the rendering speed directly, because some scenes need more rays to converge
Here you can see the new image with settings of Rawalanche…i modified the kitchen material a little (no bump, more glossy…a bit too much now, but doesn´t matter for this tests…)
This is a Raw-render, no postwork…
Rendering was much slower at the beginning (~50 minutes), but seems to be faster later on…
@maru: i´ll upload a new image with brighter background for comparison; as the facade is not lit by the sun i thought to make it a bit darker…
Looks like you have some raytracing light leaks near the ceiling. Do you have the scene centered out of world origin? You can also probably get rid of them by subdividing the problematic geometry
oohhhhh, Rawalanche; much better…used your curtain material, made it a bit more translucenc, also modified glass material…for a two hours rendering in resolution 2500/1450 its really clean, i think…
brightened up image with intesity value as i wanted to keep a dark floor…
thanks for the helpful comments…as a vray-user (a little tired of making thousands of adjustements to get a good lightened image) i´m really satisfied with speed…
still learning material settings…glossy effects etc…
i think i´m going to the next test-project…hmmm…i should´nt forget to have a life outside of corona…
