Project EYEray - is it possible to make it work with 3Dlight?

gperezcam

Hello, I'm new in this 3D world, so after having this problem I looked for other posts related with my problem, but I wansn't lucky to solve my issue.

I guess the name "Eyeray" ("Iray") indicates that it only works with Iray, but since my GPU is from AMD is a big deal using Iray (my computer freezes constantly, much longer rendering times), I was wondering if there is any way to make it work with 3Dlight.

 

This is the result: https://i.imgur.com/FUTVQKI.png

As you can see, is almost there. I wish the developer/s had push a little more the project, because looks like with a bit more work the 3Dlight render would handle the "withe area" of the eye. The ires looks great.

When I'm in Daz Studio, the eyes looks great, so I was wondering if there is any way to render it properly.

 

 

Another thing: why when I use Iray, there is a white rectangle in the eye? I'm using the naked G8M only with the EYEray. Is it because the "camera" is too close? If I move the camera, the rectangle apears in a different position. The Iray settings are the default. Is there any way to remove that? I want to make some close up renders, but if there is a big white rectangle the result will be spoiled :(

Thanks in advance for any help. Have a great day!

Looks like you are using a square light-source, and it is reflecting in the eye. That is expected, since, in reality, light-sources render in reflections. (That is what makes a reflection.)

If you don't have some kind of added light-source, then I have no clue what that is. (Some kind of light-box or uber-environment, which is 3Delight, which has nothing to do with IRAY uber-shader.)

IRAY is propriatary code that NVIDIA made for the CUDA cores. Honestly, it can be processed with any code, which is why it can be done with any CPU. The code they ALLOW for a CPU, is not "tuned", on purpose. Microsoft or Pentium would have to buy rights to "have it work better". It is simply to give you a taste of the possibility of what IRAY has to offer, so you go out and spend $500-$80,000 on NVIDIA hardware instead.

There will NEVER be an AMD conversion of IRAY, made by IRAY, or of any legal-use, if made privately. They wouldn't allow it to exist, even if it could, unless AMD buys NVIDIA.

However, AMD could make a similar version of IRAY, but they are not inclined to, as they don't have a similar hardware setup. AMD is focused entirely on "make it fast, at any quality cost", for games. Plus, I am sure that they would rather not spend money fighting NVIDIA over legal issues, for a market they are not even designed to handle and have no interest in. They want the game-market, and at this rate, they may get it. (NVIDIA is, again, pushing for the consumer/professional rendering markets, instead of the gaming market, where they are losing a footing. Though, it may be intentional, because when the IRAY fast-engine is completed, it will surely find it's way into the gaming-market as "pre and post-processing". Giving games a major boost in reality, where AMD just can't match it.)

The only other "hardware", designed for rendering like this, by a professional company, is "Silicon Graphics". They are in a new direcition now, and are being overthrowm by the NVIDIA market, for graphics rendering. Silicon Graphics is now a "Hewlett Packard Enterprise Development LP", company. https://en.wikipedia.org/wiki/Silicon_Graphics

We were once a minority in the computer world, (rendering artists), due to the high costs. Now, like super-computing creators, we are less of a minority in the computer world. Thanks to the decline of price-gougers in the market, and refinement of available sources of "the best".

First thing, thanks for your time to answer me :)

There is no light in my scene, just the G8M with the modified eyes. But since you said is a reflection, I'll have a look and see if I can find any tutorial or info. Looks like the square is "the camera", because the farther, the smaller the reflection is.

 

Bad news about the AMD-Nvidia conversion. Thanks for explaining this to me. Is just, is so close to be done perfectly... hmmm, I think I can manage to fix the "red areas" myself with photoshop.

 

I wonder if a small GPU like the GT 1030 with 2 GB is enought to render with Iray, or if it will give a better result rather than using my CPU (Ryzen 7 1700). For that price, if I can render with Iray, it would be affordable. The problem is that the next GPU doubles the price, and since I have a non-cheap AMD GPU I don't think it would be a good investment :S

 

 

EDIT: I solved the issue with the white rectangle. In NVIDIA Iray render settings, "Environment mode" -> "Dome Only" (maybe with other option we can solve this too, but so far this what I got).

Actually AMD is working on a PBR engine look at this thread in carrara forums.

The question is will DAZ impliment it as well?

Great news then, thanks for sharing the link here :)

You may have the camera headlight on. That could account for the reflection.

Thanks for your help, using "Dome only" fixed my problem, but only temporally, because if I want to use lights in my scene the problem persists.

Using your tip is 100% perfect (it was in auto but it seems that it means that is always on), because now I can use only my scene lights. Thanks again good person :)
