This image of a plate is one of the most photorealistic things I have made so far

I just made it as a stock image for a school Spanish assignment, where I chronicle the adventure of a burrito, as a pun. Reddit has declined enough that I'm not going to give them some of my highest quality work. As you may be able to tell, my dream phone to the right is the least finished thing in this image, and is much less photorealistic than the rest. The window could also be improved.

What software? And how did you render it? How long did it take?

I like the textures and global illumination.

I used Blender for modelling and LuxCoreRender for rendering. I rendered on my CPUs because OpenCL has been a bit bugged in the newer versions, somehow managing to use all the memory on my 24 GB machine when compiling kernels, and for this reason, rendering took approximately 6 hours, 58 minutes, 52.01 seconds for approximately 4096 samples. It could easily give a similar result with less render time though.

The wood and floor textures are CC0, while the cloth material for the table mat is actually one of the more interesting base materials in LuxCore, with only a few changes to its options. The global illumination is an interesting subject, as it takes place in a small extended universe. So, if the camara changed angles to look out of the slightly less photorealistic window (due to a lack of a good frame), you would be able to see the landscape, roads, and vehicles outside, although this location is a few stories up.

Thanks a lot for all that. I've been out of the game for 10 years so some of that I can only vaguely know about.

I feel embarrassed that I didn't even know about LuxCore.

I knew about OpenGL but not OpenCL.

Compiling kernels?

CCO as in the Creative Commons site?

I've so consumed with narrative, story and character arcs, trutherism, and distracting/procrastinating myself I haven't even bothered with keeping up with the animation. I figure it will all come back and I can learn Blender as well as I did all the other 3D packages.

Do you know of a good open source compositing package, equivalent to After Effects, Flame, Premiere, etc.?

Well, LuxCore is pretty obscure. Do you know about Cycles though? It is much more well-known, and can also do photorealism.

OpenCL is a fairly old API for graphics cards that allows them to do computation rather than just, well, polygonal 3D.

Have you heard of Vulkan, by the way? It's a successor to both OpenCL and OpenGL that can do both computing and game renders, and which is much more efficient and low-level than OpenGL.

Compiling kernels seems to be something related to OpenCL.

CC0 is a textures site which releases the textures under CC0.

I'm not actually quite sure what you mean by compositing, but ffmpeg is a command line program I often use for video editing, and if you mean putting on filters, can definitely be used for that relatively simply. Not exactly the easiest though, or even most widely used; I had just already been using it to stitch together my animation images and couldn't decide on which editor to try (it was also already installed). Blender has it's own video editor now, but it ended up being so weird with multiple aspect ratios that I just made a massive convoluted ffmpeg script! I hear that Kdenlive is good.

I don't know about Cycles either. I've been out of it for 8-9 years.

Vulkan, nope. I don't even know what my current box is capable of. I already know it's cheap and superior to everything I ever used in the studios years ago.

I NEED to check out CC0. https://cc0textures.com/ Looks great.

Compositing is layering images upon images building up to the desired resultant combination image, like Photoshop layers - but in animation and visual effects production it generally implies application over time.

I can't believe how shitty all the Wikipedia articles are - and these are the best ones. It's a very simple concept to visually convey with many variations and none of these have decent examples. After Effects is essentially Photoshop utilizing more powerful layers over sequences of images over time rather than just one image.

I heard about Blender as video editor but I've never tried it. I've been too comfortable with what I know. I want to go FLOSS but haven't had the courage yet.

Gonna check out Kdenlive too.

Thanks for all the recs.

I'd eat off of it!

The keyboard on that phone scares me though. I wish I had a physical keyboard, but I like the slide-out landscape keyboards. I fat-finger multiple keys too much.

Oh wow, I thought this was real for a sec until I read the comments!

Wow, the texturing on the cloth underneath actually catches my eye the most. Very well done! Great things have humble beginnings!

Not bad. If you got rid of the fork and the blackberry I'd almost be convinced it was real.

Thanks for the feedback!

I knew the phone (which isn't supposed to be a blackberry, by the way, but a concept phone running Linux) was unfinished, but I didn't realise the fork was wrong! What about the fork do you find unrealistic?

  1. It's too plain. Most silverware has some form of at least basic design on it.

  2. The way the tines are completely flat. Most forks have curved tines.

  3. The space between the tines is off. I feel like the tines should be thinner and the space should be narrower, or at least more uniform/less tapered.
