Please Critique my render.
I’m doing a grocery Aisle short animation, I will fly down the aisle then turn and face some product. My main concerns is just overall quality and realism, good lighting, and render times. I’m using global illumination now and with only 1/5 the product populated I’m rendering over an hour per frame. Do you guys suggest any render farm companies that will render my final product for a affordable rate???
Since my deadlines are short I’m guessing that might be the only option since I don’t have network render.
What do you guys think…. ? any suggestions on lighting? (its not my strong point)
I haven’t finished the liquid or look of the bottles yet, (notice 7up is orange still)
I just want any overall critiques, comments, questions, etc… please lend me your expertise and support!
thanks! (btw i’ve already reduced the brightness of the floor and illuminated the front shelving a little.. it’s in the process of rendering a new image.)

it looks like you’d probably want to turn on Details Enhancement in GI to control the bright spots at the back of the front shelves
make sure your GI settings are not overly strong (the defaults are more quality than is often needed)- the help has some good info
Make sure GI is turned off for transparent objects (just a time waster)

Thanks for the suggestions! I added tags with GI off for the transparent bottles… I added it on top of the hybernurbs group, i hope that effects it all?? i also used render instance and only added the tag to the original products. I checked the details tab on GI, i’m doing a new render now to see how it all looks… thanks for your suggestions, I’ll post updates please add any more critiques you have. I’m pretty much self taught so I don’t have any one else’s professional input on my scenes… I’m relying on you guys! 🙂
Thanks again!

checking the details tab for GI made my render times sky rocket… so i unchecked that but I did turn off the GI on all transparent objects, it doesn’t look quite as fancy but maybe i can switch it back on right before my close up on the product… thanks for your help… i’ll be filling the shelving with competitor product, it doesn’t need to be as detailed since i’ll be zooming by it… i was thinking maybe even doing a cube with a alpha channel, i’m not sure how great that will look though.

(too bad about the Details being such a load) what settings are you using for GI? can you post the scene so we can look for any optimizations?

I’m rendering it in 13 so the render times will be a bit different because GI was worked on I think but your scene as you sent it took 21 minutes to render, setting the Irradiance Cache settings to Low, Low, Least Squares, Weak, Weak resulted in 4 minutes 43 seconds – the look was not as good but it’s a lot quicker. I forced the GI in the compositing tag on the ceiling to be better quality so the ceiling would render better (5 min and a bit). Eventually I replaced the two images you didn’t send (the shelves in the back and the floor) and added AO for detail in the shelves (but disabled it with compositing tags on the lights and ceiling) (5 min 55 sec). Your results would be different with the bottles in and with 11.5 but the point is you can do a lot with setting to improve the speed.

21 minutes!!! it takes me like an hour… is 13 that efficient or is your computer better?? i’m on a new iMac i7 3.4 quad core with a 6970 2 gig video card and 32 gigs of pc1300 ram.
You’ve been a tremendous help, I didn’t attach everything in the scene because my original file was over a gig with all the product in it. Your end result looks pretty much the same as the 20 minute render… nice, i’m going to to apply these settings right now and see what happens.
Is the r13 from 11.5 upgrade worth getting?? i noticed it’s a couple thousand to upgrade… I was considering just getting Vray instead…

early 2008 MacPro 2.8 Ghz 8 core Xeon (no hyperthreading) 14 gigs ram. In rendering there is no substitute for horsepower, 3D is a harsh mistress. Mine is getting on but still is workable for me. And learning what the settings can do can save you a lot of time in GI (and pyrocluster etc)
13 does have a lot of speed and quality improvements (as did 12) and has brought the Physical renderer as well (which is sometimes slower and sometimes faster but has a different look and new strengths), Dynamics is huge, it was there in 11.5 but now it’s so much more powerful since dynamics objects don’t need to be in a cloner or fracture object etc. etc. etc. the list goes on, it’s not only the renderer(s) they are working on. Download the demo and check out the new stuff, load your scene and render.

Do you know if the render instance duplicate saves render time or only helps the machine run better??? to me it seems like the scene runs better but render times are the same… I was thinking about rebuilding my shelving using the render instance clones instead of just copy/pasting them. When i’m closer to completion i want to offset the shelves a little to make it look more realistic, i’m going to be adding a lot of other competitor product around the sunkist layout… I’m worried about how it will handle the shelves full since it struggles with just a little… someone was telling me perhaps try cubes with alpha channels, i’m just afraid it will look too cheesie or flat.

Render instances reduce RAM useage and speed up the editor display. They can speed up rendering if your machine would otherwise run out of physical RAM. Otherwise it doesn’t have that much effect on render times.
