LionDebt's attempt at photo realism
show user profile  LionDebt
Attempt 1:


No materials, nada, clay render. Wip.

Attempt 2: I added a daylight system and mr physical sky but didn't play around very much with the settings. Mostly fiddled with the materials and stuff like that. I really couldn't get the book to look 'realistic'.



And for some reason there is a strange rectangular shadow appearing on my table (closest half to where the camera would've been). Still shooting out renders on very low settings so I can see quickly what changes what. I like the way the glass ashtray came out - except it adds a good 30 seconds to my render time so I keep it hidden all the time...

Going to go brush up on some tutorials and keep pimping this image until you can smell the coffee.

Firstly you materials are very flat, no spec, reflection, bump ect...

can you post your light set up and render setting mate?

Are you using mrSun and mrSky?

take a photo of the front cover of a book you want to use & drop that in as the texture. adjust other materials to fit.

@rob -



So many fields haha... Gonna be a steep learning curve annoying the important ones :)... If I missed anything important just let me know and I'll screen grab it.

@A-S - Yeah, I was thinking of that also for the 'heat-guards' on the plastic coffee cups.. get brand names and stuff going, maybe a coffee stain or two on the table etc... No digital camera here though :(

the wood texture on the table is way too low res. find something better.
book cover - just find something online then.

yeah.. as said the materials way too basic, for developing materials id suggest you swap to photometric spot lights because sun while easy is slow and bad for developing reflection since you cant really see it much. Also watch out with that tone control, with that curve your mids are losing a lot of depth and highs will burn too fast

I reckon get your lighting bang on first, the rest will follow. I set this up in vray the other day for exactly that purpose. :)

Roger that stabby.

I've just been reading about sub-surface scattering, transparency, translucency, refraction, caustics and indirect illumination... Going to jump back into the materials and lighting set-up tomorrow with hopefully a firmer grasp of what all the buttons and dials do :)

If anyone knows any documentation or publications available (freely) online which go - not necessarily into depth - but cover these concepts from the graphical/rendering perspective.. that'd be great!

Edit: Ninja'd by mashedpot8r.

Understood :). I'll get my head around the photometric spotlights and try sort out some kind of setup that makes my clay render look the business before I start pimping out the materials.

So I've been reading a bit about photometric lights and web distribution etc...

I know this is quite over-saturated and there arn't really any shadows to speak of, but it's late and I just want to get it out there. I might re-model the table so it is more suited for an interior shot. Then add some more detritus on the table (playing cards etc), maybe chairs and in the long term - a window or some crazy shit like skirting boards and power sockets etc. And keep playing with the lights ofc :)

just a couple of suggestions...

Work a bit more on getting the shadows to show and improve the mood lighting before you go adding any more geometry. That way your render times will stay lower whilst you're balancing everything.

Are the cups floating above the tabletop or is it just an optical illusion? Maybe some ambient occlusion in your materials could sort that out.

Quite a dramatic improvement on the first render, so good luck and don't give in!

I get the feeling you're not using reference. Like, at all.

Look into HDRI lighting once you have sorted out the materials. Use Arch and Design materials where possible as they have correct energy distribution and generally just spend a lot of time as Dave says looking into references. Gather as many references as you can to get a good indication of what you are aiming for.

I agree with Dave and Coxy. Nothing in the scene looks like it's based on an actual item, except the ashtray.

Get some great source material (photos) of the things you want to make. This will make it much, much better from a modelling and material point of view.

Dave - I get the feeling you're not using reference. Like, at all.
lol! Classic LionDebt move. Let's do photo-realism with no photos. I'll get on it.

@Mike - the cups shouldn't be floating, I aligned their pivot to their base and then moved them directly onto the table, I guess it's the glossy wood that's making a bit of an illusion. I was going to place everything above the table and then use rigid body reactor (proper name for it?) so they all fall randomly on the table.

@Coxy - Yeah, I think Lighting is the 'easy' part. Materials is where I need to really sharpen up.

@Ninja Clark - yeah I agree too :)
