Subject: 4.8 and Iray


DarwinsMishap ( ) posted Thu, 12 March 2015 at 3:27 AM · edited Mon, 11 November 2024 at 11:44 PM

A 13 minute test render using an exr file for the environment map, the dome and scene settings, and an overhead umbrella lamp for Poser Reality with the Iray emitter shader.

The shirt is from Cyberpunk for M4 and the hair is Punk for Genesis.  I didn't change the shirt settings other than to use the Iray base to set the displacement to 2.  I set the hair's smoother up a few notches and added extra spec settings.

The Iray base for the skin, and some serious tweaks in the bump, displacement, etc.  The eye surface is the thin glass from Iray, tears are thin water and the cornea is thin glass with 1.45 refraction.

Not bad, considering my Studio renders end up cooking for hours with the settings I tend to use.  I'm going to let this cook overnight (I need sleep) to see how well it will get the bits of artifacts out in this.

Nice job, been playing with 4.8 quite a bit. Its great to have PBR more native to DS.

Thanks!  Considering I've rarely picked up Studio since 3A, this is quite a change for me, but I couldn't resist the Iray.  If I can get the shaders down a bit better on his skin, I am thinking I can do a second set for DS Iray users and not just keep him for P9+ when he hits the stores.

Very nice.  I hope to spend some of this weekend learning where they've hidden things in 4.8 and what it's possibilities vs. my computer might be.

Thank you!   I left it to cook overnight to remove the artifacts and clear it up, and it looked fantastic.  Just not at my computer so I can't post it today.  

I don't have the Nvidia graphic card, but I am very happy with how it works on CPU so far.  My regular Studio 4.7 renders average 45 minutes to hours, so... No complaints here.  Lol

The emissive shader allows for the addition of an IES profile, so it's not necessary to use a TIF or EXR for lighting.
You can use the internal controls for temperature and color along with IES profile for very good results.



DarwinsMishap ( ) posted Thu, 12 March 2015 at 5:28 PM

Yes.

The emissive was for the surface of the poser native umbrella that I use in the Poser'ss Realiy/Lux process.   The environment map was place into the Iray Environment for the lighting.  The umbrella was placed overhead to mimic fluorescent lights like those behind him.


Medzinatar ( ) posted Thu, 12 March 2015 at 8:52 PM

for those of you that might be interested, I include some different IES profilefile_0f28b5d49b3020afeecd95b4009adf4c.jp

Thank you for those!

This is the render from the overnight cooking- though I had a two hour limit on it, so it shouldn't be longer than that quite honestly.

i like the tattoos they are getting very close to looking realistic :-) hair could do with a bit more specular but dont know if thats just a problem with hair mats 

 A cleaved head no longer plots.

For this, I not use any added physical dome, just environment dome found under render settings.
Also, added no additional lights, all lighting is from environment map (Dimension Theory's Yosemite series)

Lighting is going to be a lot simpler under iRay, just adjusting a few parameters gives results beter that I expected.

Really, really trying to figure this out but with little success because I can't find the stuff in the listings with 4.8 without searching long enough that I forget what the inspiration was.  Would it have killed them to put it all in one folder under the product name?  Is there some deeper mystery to linkage that prevents this?


RHaseltine ( ) posted Thu, 19 March 2015 at 4:31 PM

What are you searching for? The Iray shaders should all be in one product as far as I know.


Medzinatar ( ) posted Thu, 19 March 2015 at 6:36 PM

Iray is a renderer, so it's settings being modified under "Render Settings" (screen caps posted earlier).

I be using outside source for IES profiles.  Each lighting maker supplies the profiles for their products (AFAIK, all free).  You can find easily on googles.

If you have dealing with other renderers for DS (i.e.,Luxus,Reality/LuxRender), you know that they have own materials.

The shader base and some examples for IRay are found under "Shader Presets"

excellent first render. looks almost like a bagginsbil shader
