GPU Box

[glorybound]

This is what I am dealing with. I got off the phone with them at 6 pm last night and I woke up to this.

"Just a follow up on the renderings for the project mentioned above. Did you have the renderings ready?"

[Dave_Wortley]

This is where you charge rush-fees Bobby.

I guess they had a deadline, but failed to tell me.

I just started a new project and tried RT. This is what I get and it just sits there and doesn't improve.



I launch Corona and it starts here and it is clear within a couple minutes.

Another idea: for the clients who want changes on 6 images overnight, just say "Err...no! That'll take longer than that and it will cost you to make those changes".

Although I fail to see how this is relevant to the discussion.

But you have like 36 cores compared to how much GPU? One 780Ti?

[glorybound]

I agree and will poke around on the RT forum

I now have a GTX 1080 and a GTX 980TI

Could u upload ur scene? I wanna take a look when i have some time. Don t need all the geo if u got any nda thing, just the room walls is fine for this test. cheers

Sure. Very basic!

is it coz by too little light? add few sky portal behind window, render 1 min look very clean(vray adv with denoiser)
btw, beta2 look like got some weird black dot, any other got same problem?

Sorry mind converting it to max 2016? thanks

i would say living without RT is a pain in the ass and vray RT is really slow for me, even with 4 gpus! i started using Fstorm for this reason with GPUs since its waaaay faster then vray RT in clearing up the scene and seeing actual previews, i will agree that for interiors gpu rendering is not as i would like it in any gpu renderer but for exteriors you can't beat Fstorm, on any renderer, for massive scenes i am seeing 10 minute renders at 4k, as for vray, the default settings are not so great for me, i have had to on many scenes go back to IM and LC, that you just can't beat, enough lights and splotches are non existent and that is where vray shines for me on my average pc. just wish vray RT was much better. Corona, is really faster i would agree for interiors when comparing default settings in vray and corona that is why when converting scenes from vray to corona you will see significantly faster render times in corona without tweaking a thing, its a pain trying to tweak things in vray and i think its why most people now have all the renderers they can afford, when one doesn't work just convert and go to the other. IM and LC you just cant beat that though comparing vray to any renderer for interiors, its crazy fast and there you can tweak like crazy to make it really faster, wish that was developed some more to get rid of splotches in low light conditions rather than focus on BF which is a pain in the ass and not for regular pc users stil. That being said, the talk is gpu rendering will be the future of rendering, not sure how true that is, but its nice how easy it is to add more gpus and see faster speeds.

Well, idk what u guys do wrong or happens in ur systems, but this is an RT gpu render in 53 sec @ 1080p with 2 x 980ti with noise threshold 0.02 (kinda high but still its pretty clean for that amount of noise).

I used a vray sun/sky but there is no direct light in here, i have a portal in two small window openings. The material has 0.5 reflection of 150 at 170 white value.

I do not do interiors at all so idk any tips or tricks for that matter.

As for fstorm, cannot be by definition faster than RT if u use BF/LC for RT. Mathematically an unbiased solution cannot be faster than a biased solution. So idk what is ur comparison measures here.
Never touched Fstorm, cause is a premature version of octane. Try adding some DOF in octane or some high roughness and see how much it takes things to clean up. I guess Fstorm is the same. Gives u 90% of the image in few seconds and the rest to actually clear needs x20 of that time. As said, i havent tried Fstorm, but i m pretty experienced with octane which is practically the same engine evolved more.

Anyhow, idk if u know this, but u can use RT in production mode besides live viewer. And from there u can choose LC for secondary bounces.

To me the most consuming time is not the final rendering is all test renderings that you have to do.if you are using RT to check lighting and materials to get faster feedbacks you are working more efficiently. Trying to get final images using only GPU is today to expensive.
I have a small farm but lately I was using commercial farms to get my renderings done if I need them in few hours or minutes... paying for a farm service is more practical to me because I don't want to spend thousands in video cards and 2 months later something new come up.
The technology and products for video cards move too fast that you are obsolete in few months anyways.
