Iray Material Presets

I just got a new PC with the following specs;

8th gen i7 processor (4 Cores 8 threads 1.8-4.0 GHz) 16 GB RAM and 512 GB SSD drive.  It also has a nvidia Geforce MX130 card (The card is 2GB)

My question is could I expect reasonable performance if I were to use Iray as my render engine?  Most of my renders are pretty straightforwrd - 1 or 2 models, standard lighting nothing crazy.  I had been using 3Delight because my old machine is a dog and bought the new machine thinking I would continue with 3Delight.  However looking in the Daz store I noticed that many new products only have Iray material presets. 

2 questions - can I expect reasonable performance with the new machine?  And, is there anyway I can get Iray material presets to work with 3Delight?

Thanks!

Cammy

    2 Gb of VRAM is very small. You're going to have a very hard time getting scenes to fit in there. That mobile card is not going to render very quickly even if it does get the scene into VRAM. You also cannot expect a mobile I7 to handle iRay rendering well at all. So that laptop will struggle with iRay any way you look at it. 

    As to moving iRay materials to 3Delight? Not to the best of my knowledge.

    You can check out https://www.daz3d.com/rssy-iray-to-3delight-converter-and-merchant-resource for converting Iray to 3Delight. I don't do 3Delight, but I've used their 3Delight to Iray converter and it works pretty well, so I would assume the reverse works well too. 

    And as kenshaw011267 said, with 2GB of VRAM, the system will fall back to CPU for pretty much every render. Before I upgraded my video card, I had a 2GB card and pretty much anything more than a single character with clothes and no environment would be too big. If your PC has decent cooling and you can let it render overnight, CPU isn't bad - I used that setup for over a year before I got a GPU with enough VRAM to render most scenes. You might look at Scene Optimizer (https://www.daz3d.com/scene-optimizer) to help with that, but again, you'll probably end up falling back more often than not.

    You can apply the base 3delight shader, or ctrl+click to apply it and ignore the maps. But as with going from 3delight to iray you will likely need to make adjustments to get the best visual results.

    There is also a free script that helps with getting maps into likely channels https://www.daz3d.com/forums/discussion/139326/irayto3delight-conversion-script/p1

    And a paid for utility that helps check surface names and apply shaders presets already similar to different types of surfaces https://www.daz3d.com/rssy-iray-to-3delight-converter-and-merchant-resource

    They aren't going to match exactly though, and if you are looking at custom iray shaders it is likely that they won't match well at all. iray and 3delight both do things differently than the other, and each has strengths and weaknesses for types of shaders they do well.

    A lot of products still have 3delight presets as well, so watch for that.

    Another possibility is to eschew iRay entirely and use the new aweSurface shader for 3delight.

    Because you only have the one card, you wont even have access to all 2GB because it is being used by windows to display everything on screen as well.  If you choose to use Iray, you can use your card but you will need to tweak your scene to reduce resource usage.  For that, I would recommend my own product which was made for such a purpose - https://www.daz3d.com/resource-saver-shaders-collection-for-iray

     

    If you stick with 3Delight, you should see a reduction in render times over your old machine with the same settings as before.

    Thank you so much for all of the help.  I really appreciate it!  It seems like I have options now I just need to figure out what to do.  I'm definitely going to stay with 3Delight as I understand the limits of my Grapics Card.  I might try Reality again too.  I know Reality uses GPU and CPU together.  Does anyone know if Reality is still a viable product?

    With my new machine I've rendered scenes that would have take my old machine over 2 hours in about 12 minutes - so I'm happy there.  Now I just need to figure out how to get improved renders with 3Delight or try Reality again.
