ok.... wanted to try one of those flashlight renders with keyshot. It came out nice i think. Its not fully complete but then again i will just post it. Being a maxwell render users I wanted to see if KS can indeed do tis and yeah, it can. What do you all think?
That's not too bad at all if it's just the one light and black HDRi - Not sure what's causing the hot pixels so there is till more tweaking to do :)

your are right.... didnt really catch the hot pixel. i let it render all night on the work window and just screen shot it. Maybe rendering outside might fix it? But yes, its only one tiny sphere inside a shiny metal box. looks even better with a slight bloom added from PS. Ill post it.
here is one with a slight bloom to it.
Hi Syrom.
Think it looks better without the bloom.
I think adding a bump map (noise or noise fractal) to the table tiles would help improve the realism. At the moment the reflections are way to perfect. Also try playing around with a roughness map if you have access to the material graph.
I now you can push it further!
for comparison, heres one from maxwell. 1 hour render time so its noisy.

yup..... i just started yesterday evening and it requires a little tweaking like the bump for the reflection and a few other things and it can be a very hyper realistic shot. ill play with it later.
Currently exporting the scene to Thea. I want to see how that render performs. Ill post it but not sure if mods allow other render works.

I do have the material graph. How would that help? I never really played with it.
Turning into am interesting thread ....
When this scene says Flashlight render i am now wondering if you mean torch or flash light as in camera flash. If you are doing torch type flashlight it would probably work better with an appropriate IES file.
@Syrom - Posting other render engines results for comparison purposes is fine as far as i am aware :)

Nice! Ive done comparisons renders before here. But just making sure again. On this render, flash as in a dslr camera flash. Not the torch type. Basic shiny metallic rectangle box with a sphere inside with a high white emitter on the sphere itself. I will improve the textures further and maybe add a few more items to see wha I get.
i got this with Thea render. A total of 0:24 seconds to render. Thats 24 seconds! lol. But man how much I hate the UI. Also I used the Presto Engine, a hybrid GPU+CPU based solution. What bummed me out was how I couldnt get the light to glow stronger on the tiles in the front to get that blown out flash effect. If i increased it it just lights up the rum too much leading to a less flash effect output. But interresting output though for only 24 seconds.
Ok... just tried Thea again but using its TR1 engine in which is as fast as my pet snail. Pretty much its like maxwell using this TR1 engine. But.... its giving me a way better flash lighting over exposure like ks or maxwell. So its Presto engine is lightning fast but not all real world calculations are bring processed.ill post the image once its done.
Syrom
Btw... see that knife on the wall? Id like to use it on Thea's UI. :p
OK.. Here is the Thea in its TR1 engine at 2 hours render time. Looks very similar to Maxwell.
Ok..... this is Thea using Presto (MC) engine. Took 1:45 seconds to get to this. Not bad.
ok...... looking at all the renders now I noticed the KS one is too yellow. So i fixed it by leaving the full simulation at full default but dropped the ray bounce from 24 to 3 and that reduced the yellow tint the wood was giving off. Ill keep that in mind for future flash type renders! Heres the result from KS.
So far i think KS has the better looking result despite producing hot pixels.

I always loved the flashlight lighting style, they were very avant garde when they first appeared years ago weren't they ?... used the effect myself a few times in MW, very cool indeed
Great comparisons by the way, the KeyShot version looks very nice.
After looking at the renders..... im leaning towards maxwells as the closest to reality. The KS does come rather very close though. I though it was not going to be doable really. So im pleased and the results are very impressive for its own speed.

I remember seeing my first flash type render, its what got me into maxwell. But yeah, it was a amazing experience looking at a render that looked so real.
I think by and large the difference between these images comes down to a difference in tone mapping in the renderers that produced them.
Maxwell uses different response curves for the final rendered output, so direct comparisons with KeyShot are tricky. :)

Yup... its hard to get it exactly 100% identical. Its just the algorithms of each package. But they come close. Im rather still new to ks so im not exploiting its full potential. But... im still working on it and its improved by 25% more. Ill post once im done tweaking it further. Im also fixing some geometry, chamfering edges and adding a a thing or two to bring in more shadow. Only thing i cant get to work is importing a maxwell camera. No matter what import format that i use, ks wont import the camera. I tend to use .obj and checked the import camera option and it still dont work. Odd. So im just eye balling the camera.
ok..... heres the final. only ran it for 20 minutes and it needs more time but want to show it since im leaving my station atm. pretty damn good i think.
Nice, but to get rid of those weird horizontal lines, render using maximum time or samples

Yup... only ran it for 20min. 1 hour cleans it up.
ok..... i let it run for 2 hours. cleaned up 100%.a few hot pixels popped up but oh well. I did change the material for the ceiling light... maybe thats the culprit. time to move on. thx for the feedback.
Hi Syrom.
It's looking pretty cool.
I was wondering about the position of the 'flash' relative to the camera.
Do you have it above the 'lens' as they are typically positioned on real cameras?
It looks like it's a bit below at the moment, but it might just be me :)
ok... did a sun version of it. this the last.

Good eye.It should be 1 inch higher if its a dslr and 1 inch to the righ if its a standard point and shoot. I panned back so you see where its at. Currently its almost center of the camera. I think ill fix it.
one the good news, i sent the pic to a girlfriend who knows nothing of 3d. i just ased her what she thought of this picture. she said " are you in someones kitchen?" lol... she thought it was real... she was blown away.
ok... after taking a good look at the flash position... it was off even from the center a bit. SO NOW... its dead center and about 1 inch higher than the camera eye. im rendering and looks better.
ok. heres the results with the flash dead center and 1 inch above the camera. not to happy seens the shadows are hidden well. so i moved the flash 1 inch to the left and im currently rendering it.
Ok.... real final render. I only let it run for 25 minutes so its got some noise and lines. But we have the general idea in how a flash light render will look. heres the final with the flash location of a point and shoot camera.
Cool, syrom!
I've got to do one of these myself sometime :)
It's nice to see such a dedication for adjusting small changes.
