That makes sense but is there an ideal number where the image is considered finished?

Like said s/p is quite scene depended. Generally texturemapped surfaces do forgive noise better than surfaces without. Usually few hudred s/p is enough... but it's up to eye.

Yeah the cornell box sample scene will look decent at around 100 s/p, were as Bradley's desk i let it get to 400 and it still needed more

I've had some scenes look great at 10s/p where others go past 3000s/p and still seem to need more. It all depends on how the scene was lit. The more bounces the light has to go through the more passes it will need to clear.

I think at the end of the day the client should be sending there scenes with s/p already set up and the farm provider should have no need to change the scene at all, load, render, simple, if the s/p is wrong or any other setting its down to the client.

If I was running a farm, it would be as automated as possible and just let it do what my client set the scene as

its easy enough to do a test to see what the s/p needs to be


Nigec,

That is what I was saying.. That the client would specify before saving their .pack the s/p they wanted the image to clear to. "Number of Passes" is an unreliable method if you're paying by the hour since 1 "pass" on the render farm is not an unchanging metric. What If I add 20 nodes to the network? Then 1 "pass" would be 20x more clear than it was before I added them... What If I had an entire rack go down for a day? If there were 5 nodes in that rack, then the image wouldn't be as clear as it would have the day before... s/p isn't dependent upon ANY outside factors, it is THE ONLY metric Thea provides for ensuring a specified result in terms of clarity of the image.

A rendered image cleared to 100 s/p on a 1996 Packard Bell running windows 95 will look the SAME as 100 s/p on a 10,000 node Render Farm. It is independent of hardware, or any other metric when using Thea. (now if only I could figure out how to get my old Packard bell to run Thea LMAO).

Right now, with a simple .pack file we can render your scenes with no trouble at all. And in fact, we'll do it FOR FREE!!! We need scenes for testing/optimizing the workflow - as well as a variety of other things...



Why don`t you build your own testscenes?

I don`t think it is a good idea to send work-data to someone I don`t know, without any contract.
How can you ensure that you don`t backup any data for your own commercial purpose.
show me a running business and references.

all this sounds strange to me


Well, I suppose it's inevitable that there will always be cynical people who assume the worst of most situations. So, instead of being offended - I'll just do as you asked:

I am a partner in several different companies. The project that recently led me to Thea is called VinMod, where I am designing a Modular Wine Management and Storage System with a wide variety of technology-based features. I have (in the past) owned a dozen or so companies, and been a free-lance designer for many others. I work with several very large companies, one of which is Eternal Asia, Americas Division. I would be happy to PM you Jimmy Davlerous contact information - He is the VP of the Americas division. Eternal is a ~5.0B(usd) Company and is (if I'm not mistaken) the 20th largest publicly traded company in China. I ordered roughly $1M worth of product from him in 2011 - I'm sure he'd be happy to give me a good reference.

I must say, it seems a bit implausible that I would spend $25k+usd on the hardware/software to construct a renderfarm, just to bilk a few Thea users out of some scenes... In the image I've attached you can see 1 of the 3 racks that are processing scenes. At the moment only 1 rack is up and running (still ~$7k+ worth of hardware alone) - however within the next few weeks I'll have all three up and running. I'm not familiar enough with thea yet to construct scenes which are "realistic" in terms of testing the NEED for Ghz (in terms of the ratio between money spent and necessity of Ghz to clear average-to-difficult scenes). Aside from that fact, doesn't it seem like good advertising to offer FREE rendering to anyone who wants it (while serving the dual purpose of determining "how much Ghz is sufficient as an initial investment")?

It amazes me that I'm offering FREE rendering of complex scenes (using hardware I've invested $1000's into) and yet you're concerned I might steal some meshes that you've built?... Well let me put your fears to rest (something I would have done had you PM'd me to have a scene rendered) - Attached is a my Non-Disclosure agreement - I would require it to render a scene for a client. It denotes non-disclosure on both sides of the relationship. I'm sorry that you were made to feel wary, I hope this clears up all your "fears". If not, the address to my product studio is on the NDA, feel free to fly out and take a look at my studio yourself. It is situated in Dallas, TX with frontage access to Main Street - it's not hard to find. I've also put my toll free number on this post as well - feel free to give me a ring.

can`t find anything called "Speculative Reality". what is this, another letterbox company? I can only find Cobb Professional Services.
Maybe you should post a direct link to some references you did mr. freelance designer.
