Arrow [WIP] Rainy Street

Hi folks,
this is my latest work, I called it Rainy Street, and as the name says, its gonna be a render of rainy street shortly after a raining. I decided to create architecture typical for the old quarters of my birth town Bratislava, though the created street will be purely fictional.

Thing is Im trying to achieve realistic good looking render and during my work I got stucked little bit on road and sidewalk shader to make it look wet, so I spent few hours with tweaking and this is what i got so far, I would like to ask if you guys consider it good:
(I placed red proxy objects on places where are already finished buildings but I replaced them for now with cubes with highly saturated red color to see its impact on reflections and lower the render time)



Lighting is achieved by HDRI skydome and rectangular light. I decided to make this personal work as my first Vray scene to learn the basics like VrayMtl attributes, VrayBlendMtl, linear workflow, lighting etc..

thanks in advance.

Im not sure with the person scale, maybe he is too big, idk..

Hey man,

Not bad for just a few days of work! Are you still trying to make the street look wet? I'm not sure that sky really communicates that it just rained.

It may also help to add some angular falloff on your raytraced reflections. You might see a setting on your shader with something along the lines of "fresnel effect" or "incidence". The reflections on your street look to even. I would think that It should appear to get more reflective further down, as the angle with the camera gets sharper. Some dirt and debris in between the cobbles on your street could help smooth out those sharp gaps between the stones. Maybe a few potholes and missing stones could break things up a little as well.

Hi, thanks for reply
yes, Im still trying to make it look wet, you was right about the sky, maybe it doesnt fit to the atmosphere. Its a sky from HDRI map, so maybe I will just replace it in photoshop.. or maybe change the whole hdri map to get a correct GI ?

Im not sure what you mean by "angular falloff", as I said Im new to this :/ but probably it has something to do with my fresnel IOR which is set up to value about 7 or 8 .. Im not sure if its correct value.. Ive found sometimes in the tutorials term like "fallof map/texture" but I clearly dont understand what it does (I used diffuse, bump/displacement, reflection and glossiness and those I understand)
Yes, removing some stones wouldnt be such bad idea, its just a matter of displacement..

Nice. Just a point, the stone on the pavement look massive. I think you could scale down the pavement quite a bit.

The scale of the pavement and white stone borders looks fine to me. It's similar to what we have here in Holland in some of the older towns. I do think that the gaps between the stones could use some filler, sand/grit. They tend to fill up with that stuff after a while as well as the sand gets added in when they get placed.

To get good reflections on the pavement first of all you'll need something that it's going to reflect. With this angle it's going to reflect mostly a yellow building at the end of the street which is not bright enough. What I would suggest is to move that building away and place there some good sky texture with bright clouds (some HDRI) or even your light source.
And of course, as shadow92 suggests, check your fresnell reflections option to be on. This will give you some nice realistic highlights.
Hope this helps.

if i would move that building away and replaced with sky that would appear like some cliff and not the main street

My fresnel option IS on, I wasnt just sure with the value, now its like 7 or 8... I will have to play a little bit with that...

Again, thanks guys for comments, I will take a look at it probably today and post a result here.

So, this is what I came up with.

Note this is raw render without photoshop adjustment etc (I will maybe replace the sky in PS with something better), so there are no peoples or smoke etc...

@sand/grit between stones: I added it but Im afraid due the small area between stones its not much visible.

@road highlights: I played with fresnel IOR and icreased it to 9 and added slightly more reflections, its maybe a drastic value but it produces good looking wet result I think..

@sky: I chose this one, more cloudy and it now looks more like its after the rain.



opinions ?
