HDRI and Sun+sky test render.

[Image Box Studios]

Hi to everyone.....i am hereby posting my first, 2 test render images without any post process, one with Hdri setup and another with Sun+sky mode. i think Hdri render has more depth and contrast as you can see here, we can easily define sofa wrinkles with Hdri setup. but with sun+sky mode i lost the details.

what do you guys think. also i have another question that how to remove white small dots[sparcles] on wall below paintings. how can we render a noise free image with Hdri setup.

Sun+sky mode took 6 hour for render 3000px image size with 40 passes[MSI=200, and HD Cache- Record Quality=1024].

Also how can i reduce my render time.

Thanks.

First, i would reduce all of your bump, its just too much.
Those doors really need some work, is it composite? Wood? Its hard to tell.

If that's the only window your gonna keep there really isn't any point of having HDRI lighting.  And did you add a portal in front of your window?
I really love your floor, would love to know where you got the texture :3
Carpet is nice, but it almost looks like a towel.

The second picture is better,

Since the interior has very small window, I would suggest using portals.

Hi Cyanhide...thanks for your reply. As i am testing corona, so i leave the details but i will definitely reduce the bump value on doors and wall.

You mean to say that if there is a small window in my room, i avoid hdri setup. yes, i did a portal on window.but i have a issue with portal light. actually i created a plain with single face and applied corona portal material on it. but i want to know that if i place a portal on window with single face then what will be the direction on that plain's normal.

Floor material---its is very simple and created by myself. here are the floor settings:- Diffuse level=0.7, apply floor stone texture on diffuse slot, IOR=1.52, apply falloff on reflection and lower black color value to 48,48,48 in falloff. thats it.

carpet look like a towel- ha ha ha....ok i will change it later.

again thanks.

Hello keymaster....yes i used portals on window with hdri setup. i have another question that can we adjust gamma value in vray hdri  to lower for getting a contrast in corona renderer, is it work with corona? and is there any way to  increase our hdri map resolution like vray.

Something wrong with the reflection on the doors.

Hi maru thanks for the information. but i have few queries, actually i am not getting these lines exactly:-
1.-Massive use of instancing.
2.-Disable/reduce filtering in 3dsmax bitmap texmaps[where is this option].
3.-Convert the opacity mapped objects like leaf to geometry.
4--How can i know that how much rays/second, my pc generate.
5.-Usual values of rays/sample is about 5-50 for PT samples set to 16 and light samples multiplier 1.
6.-what i choose:- highrays/samples or lowrays/samples.[i am confused].
7.- Try keeping albedos of all your main scene objects under RGB 180, and get whiter walls by brightening light sources.
8.-Decrease albedos of your scene objects to at most 70%, or RGB 180.
9.-In Rays/second heading,i got this line:-Increase PT samples to at least 4 and in rays/samples heading ,i got this line:- Decrease PT samples or light samples multiplier to default values. here one heading tell us Increase PT samples and another Heading tell us decrease PT samples.[ i am totally confused with these two headings.]

Thanks.

Is High rays/samples good for achieving quality render in less time.

Actually it was a converted material from vray. so there are reflection problem on doors but i will manage it..thanks .

Hi.....here is final render with some post process......sun+sky mode.

Change the doors and you have an amazing scene mate, the doors are killing it.

Hi.....yes, you are right. but next time i will definitely remember your words,but this time as its my first render in corona,  i just wanted to see the corona renderer behavior.

and again thanks for your valuable comments on my first post.

Good render Image Box Studio International. My only recommendation is tweaking the TV screen brightness to something less dark.
