Renderotica

Thanks so much for responding! Really awesome that you're still active. Overall an incredible product! In order to deliver a file you can actually open on your end, I've recreated my scene using generic GF8 models & materials. The backlight burn effect is not as pronounced on the generic models as it was on the custom ones, but it is still there, visible both in renders and the iray viewport. Below is a Dropbox link with the scene file, the HDRI file, and renders from both this generic scene and my original scene. Let me know if you have any issues with the files. Thanks so much for taking a look!

Hi, hope you don't mind me weighing in on this. I downloaded the test scene as I was curious. It happens that I had the BETA version of DAZ Studio open at the time. I rendered the scene and was surprised to find I had no red spots. I closed the BETA and opened up the Public build. I rendered the same scene and there were the red dots. So it appears to be something in the way the render engine is behaving in the current Public build and has been 'fixed' in the BETA.

Full Scene (cropped for upload) and then Camera 3 to show that the results are able to be reproduced.

If you really want to see what is crazy, download both closeup images. If you have the ability to open them in an image viewer software where you can 'flick' between them you will see that the Genesis 8 figure in the BETA image has a thinner hip. How that is happening with the same camera in the same scene rendered in two variations of the same program is waaaaaayyyyy beyond my knowledge.

Hmm I wonder if this could also be part of it. Don't get me wrong iSource is an amazing vendor when it comes to textures, but I've seen them use features of Shaders (even going as far as using custom Shaders or UVs) that break functionality of certain scripts and features of grafts and shells. I mean like I said terrific vendor, Just with some of the ways they set up textures and shaders doesn't always work well with others' products. 

I mean with Haruchi's testing it isn't 100% the problem, as there is obviously something changed internally in the current Public Release of DS compared to the current BETA release, but just kind of a warning that sometimes iSource does some odd things with the overall surface settings that can cause issues with other products working right with their textures (It usually boils down to copy material scripts not working or not working right though)

Quick update on this, DAZ has launched Studio 4.22. This problem no longer appears in the latest version.

That's great news, thank you for the update :-)

I´m trying to fit NGV 8 to a custom Genesis 8.1 figure and it works like a charm. But for some reason, I can´t use some of the scripts.
Changing the anus color for example leads to DAZ reminding me to select a Genes 8 figure.
Same thing happens for all the effect related scripts.
Did I mess up something during the update process or are some of the scripts simply not updated for Genesis 8.1?

 

Hi, these scripts require you to select a character in the scene before they can run correctly. If you select NGV8 or other nodes, they will remind you to select a character, such as G8F (including G8.1F) or G3F. 

Hi, I am sorry to be a pain in the neck and coming back with a problem that I thought was solved. I think this may be caused by the creative ways vendors make their textures/materials. The ongoing issue I have seems to be with the "genital' surface the NGV8 Expansion pack creates in the character surfaces. Often, I can use the fix 3feetwolf provided a while back for G8.1F.  That didn't completely fix the issue. It's still been ongoing. Today I bought Sienna HD for G8F. Build the textures, apply NGV8 as per the Expansion and character is white (no texture for the torso surface) and added "genital" surface also white. After several goes, re-starting Dax Studio, re-booting PC. Trying other textures and copying texture images. All to no avail as I wanted Sienna's eyes, lips etc. and any time I tried to apply these, everything massed up. So I tried copying Sienna's torso texture. Applied NGV8. Copied the texture back to the torso and NGV8. I then used a successful NGV8 as a guide and copied he image files across for the NVG8 and new genital surface on the character. NGV8 looked as I wanted. Unfortunately, the legs didn't work. Please see attached images.

Probably not the help you are looking for but I can only echo Grimmbright. I have just added NGV8 to Sienna HD using the Expansion Pack with no errors and everything worked as it should. I chose to add a colour to all surfaces in the pop up window to make sure it created all maps it could possibly do.

Methodology -
01 Load Sienna HD
02 With Sienna HD highlighted in the Scene tab run the 00 - Customize genitalia for current character
03 Wait for all maps to be generated
04 Run 01 - Apply NGV8 to current character

NGV8 loads onto character correctly. Settngs chosen and result below
