Hi guys,
I have a sequence of 3 characters talking and idle around,
without any background, 4 lights,
1280p x 720p, 30fps,
Iray with interactive render mode, iteration 100, GI mode OFF,
total of 1600 frames,
render to image sequence and MP4,

it takes almost 1 hour for rendering 30 frames,
meaning to say the whole animation will take me 30++ hours
is this normal? Or am I missing something?


My PC spec:
Intel Core i9-9900KS CPU 4.00GHz 4.01GHz
32GB RAM
64 bit Windows 10
Zotac Rtx 2070 Super
1 TB SSD, 2TB HDD

That sounds to be about normal for getting an Iray video render.

Thanks Gerry!

At least I can now stop worrying for the rendering.
In this case, any chances of increasing the speed with hardware upgrade?

I read a few post here talking about upgrading GPU or double up GPUs,
if I am to add another rtx2070 to my PC, is that benefit to the rendering?
Or is it better to just change another higher vram GPU?

Thanks.

Iray will use multiple GPUs for rendering and the more VRAM present the better. iClone, on the other hand, does not make use of more that one GPU at present.

@lup1224 - just some thoughts-
Think of it this way - we don't want it to take a long time, but the GPU is actually computing light rays from emitters bouncing off of different surfaces. 
So basically it is running math calculations, and this is what takes the GPU time.

With speed - If you have 10 of the same GPU, you can essentially divide that 60 minute computation time by 10 (6 minutes), but then data must for each calculation likewise must be fed into 10 devices vs 1 (lets say 1 minute load x 10 = 10 minutes), so it is a trade off when it comes to maximizing the total process time.  Sometimes having 5 GPU is actually faster than 10, in ultimate processing terms because the total process speed (load + render) is what matters.

What you can do is make it really worth that time.  Run sample renders at very small resolutions and make every light ray the best it can be (make it look the best it can).  Then, when you really like what you see, render the project at your full resolution.  Because otherwise, if you just go in and try rendering a default-looking scene in iClone, you will pretty much get only a slightly-improved version of what iClone can do by itself with the native render.   
Remember, you can modify the Iray settings all by themselves completely separate from iClone, which sounds complicated, but it can really open the doors to realistic renders. 

PS - VRAM is amount of space for scenes with a lot of materials, but for speed, you want to look at a GPU's core clock.
The best right now would be Titan V, Titan RTX, and 2080Ti.  Expensive, but they are the fastest.  Titan RTX has 24Gb Vram, which makes it more future proof, while the 2080Ti has 11 Gb Vram , but is less expensive.
If you were to win a free-GPU prize, and you could only take one, take the Titan RTX!

I don't suppose you can send it to an Iray render farm as another option ?

Got that! Thanks for your precise command!

Tony, thanks for the tips! I will certainly try that way next time.
I have currently using a rtx2070, so for right now, I might just get another rtx2070 to reduce my rendering time.

The upgrade to 2080 ti will be the next step for me certainly.

Thanks again!

This certainly a very good option if project is at the bottleneck, thank you!
