WIP 9/29 - Bump

Here's the latest with the rendering today.  The background in supposed to have a bump on it, procedurally generated with a grid texture node, but for some reason nothing shows up.  I haven't figured it out yet and it is bugging me.  I have tried all sorts of things, and the tutorials online so far haven't been any help.  I need to figure this out because it is a very important tool.
Let me know what you think.

Still rough textures, work in progress

More textures, WIP 9/28

As of right now, I've been putting in the rough placeholder textures.  Even though some of these look good, they aren't anything as good as I hope to get them to.  I still need to refine the textures/materials so they look exactly like the materials in the picture, and then i need to add all the dirt, scratches, etc.  While going through the scene, I've not only seen some geometry issues to fix and started fixing them, but I realized a giant error I'm not sure I want to fix.  It is not easy to see, which is why it might be worth cutting the corner, but the inner brown box that holds all the tongs and scoops (and the stuff within) are supposed to be 3 boxes side-by-side, and one is at an angle.  Not sure how I missed that before, but now that I see it, fixing it involved major overhauling of part of the scene.  I might go back and do this, but not yet.  It is something I will consider, but since it took so long for me to realize it, it isn't a glaring problem.
That being said, I am also struggling with the textures.  I put a granite texture on the counter top and it is not exactly behaving as it normally does.  Renderman is treating it differently so now I have to figure out how, if there is a fix, and how to make it look right.  But for now the placeholder is fine.  All that's left is the wall, the calk, the baseboard, the jugs on top (and their liquid), the small rivets, the limes, adding the geo and textures for the powders, and the background wall, which ultimately should have a metal basket and a lemon in it, which is something else I might add later, but now yet.
Let me know what you think.
(Also I think the IT is putting things in linear space, but for some reason it put this output from rgb and converted it as if it was linear, which darkened it.  So it is too dark now :\  I'll fix that.)

Converted on-the-fly from linear to srgb

Incorrectly converted from srgb to srgb as if it was from linear to srgb, making it too dark.

Materials in Progress... WIP 9/27

Here is where I am with the first step in the materials: rough blocked in materials.  Again, no lights, unrefined textures, no dirt or grime or imperfections yet.  Just putting something basic in place so I can start the process of putting things together.  Also it will be full of noise cause it's only a test render.


Tell me what you think so far.

More learning

Again, not much to show yet... but I finished some tutorials and I'll be starting the texturing next.  I have a few blocked in materials.  My goal is to put in blocked materials, then go back and refine each one to look at realistic as possible, then go back again and add dirt. grime, grunge, etc. to mess it up a bit, and then do one more pass overall to make sure it matches close to the original photograph.  Here is the start of a very rough blocked in pass.  Lighting comes later.

Just a hint of color

Not much to report today, except I've been doing tutorials for Renderman materials.  Good stuff!  It'll take getting used to with some of the different parameters/attributes, such as presence.  Well at least here is a small section I was briefly experimenting with.  It is way too clean and not refined and has no lighting, as it is just blocking in something, mainly messing with the shaders.

Some color at last!

Tutorials abound

Update for tonight isn't as exciting as I'd like it to be.  Had Maya crash and lost a bunch of work I did.  Oops.  Should have saved.  But I decided that most of what I was doing was flailing around in the dark with Renderman.  While that sort of technique is great and all, I figured maybe I should spend some time looking at tutorials on Renderman and the like.  I learned that since the newer Renderman versions (19 and 20) have come out, they've added a whole new rendering system.  The old one was called REYES (Renders Everything You Ever Saw), and the new one is RIS.  Might as well jump into the new one for now.
One of the cool things I found out was about the unusual Image Tool... or IT for short.  It is just like the render window Maya gives you, except a separate program Renderman uses.  And it has some cool features.  By default, everything is in Linear, with easy tools to adjust for srgb.  It also has a much better image comparison system, using catalogs and wipes, so you can compare between old and new renders.  It even lets you select objects and shaders in Maya from within the IT.  Very cool!
So for today, I don't have anything newly rendered to show yet, but I have spent many hours just getting used to the new interface of Maya 2016 and the new tools in Renderman.
I have to find some more tutorials on this stuff.  If anyone knows of some I can get access to without spending money, please send me a link and I'll take a look and review what I find on here.

WIP Sept 24, 2015

So, again sorry for the delay in updating this.  Here is the latest Work In Progress.  I will be doing more soon!
