Title: jg first test
Post by: JG_monomiru on 2013-06-29, 20:30:51

i just recently discovered corona - thanks to lasse - quite a nice render engine with some potentials. did my first test today with an simple scene made in vray. I used the material and light converter script from the forum and hit render.

I'm quite satisfied with the result for no effort. Hope to find time exploring the engine and the settings in depth.

Seems very slow for such powerful CPU, 2678 is more powerful than 3930k (which achieves over 5mil/s rays). Can you run the benchmark which is on this forum ?
What settings did you run this on ? Default PT+PT ?

i did the hd cache, but everything else is default.

Did the benchmark and also the comparision to the vray rendering.

i guess i need to work on the render settings in corona... i guess then it will be faster. benchmakr was promising.

How come?........2 hours VS 13 minutes ???......speechless difference considering d benchmark performance. Is this alpha V5

yeah its the alpha5 and set to hd cache...

i dunno after running the benchmark i couldnt start a corona rendering in max. might reinstall corona again.

Can you post the scene (corona)? I'll try to set it up.

it is an currently ongoing project, so i can't post you the scene.

but thank you.

1): you won't have a valid comparison unless you use Bf+LC in Vray and Pt+HDCache in Corona, but that just as a sidenote ;)
2): The converter script will not make "good" materials. You still have to make sure that your window glass is set to thin or hybrid mode (depends if it's just a polygon or a box with thickness). That can make a huge impact.
3): You can try to use portals unless you would need lots of them. Keymaster told me that there is a usable limit until those portals will work with embree acceleration.

thanks.... i'll look into that.

just figured, that there is a big discrepancy between Ray/s in benchmark and when rendering from within 3dsmax
 benchmark i got nearly 6million rays/s while when using hd-cache or pathtracing in 3dsmax its around 1.2 million

ok, figured it depends on complexity of the scene. simple cornelbox is around 36million ray/s.

so i better look deeper into the whole engine before posting more stuff. but as i said its promising for a first try
