If an **Iray render in DAZ Studio is completely black**, the most common causes are:### 1. No Lights in the Scene
Unlike the default viewport, Iray requires actual light sources.
Check for:
* An HDRI environment map
* Distant lights
* Spotlights
* Emissive surfacesGo to:
**Render Settings → Environment**Make sure:
* **Environment Mode** is set to **Dome and Scene** or **Dome Only**
* An HDRI is loaded if you're relying on environment lighting---
### 2. Camera Inside an Object
If the camera is inside a wall, prop, or character, Iray may render black.
Try:
* Switching to another camera
* Moving the camera back
* Looking through the **Perspective View** first---
### 3. Environment Intensity Too Low
In **Render Settings → Environment**:
* Increase **Environment Intensity** to 1–5
* Check **Environment Map** is not missing---
### 4. Tone Mapping Exposure Problem
Go to:
**Render Settings → Tone Mapping**
Check:
* **EV (Exposure Value)** around 13–15
* If EV is too high (20+), the scene may appear nearly blackQuick test:
* Set **EV = 13**
* Render again---
### 5. GPU Memory Failure
If Iray runs out of VRAM, rendering can fail or produce unexpected results.
Check the log:
**Help → Troubleshooting → View Log File**
Look for:
* "CUDA memory allocation failed"
* "Out of memory"If so:
* Hide unnecessary objects
* Reduce texture sizes
* Render with CPU enabled---
### 6. Corrupt Render Settings
Try:
**Render Settings → Editor → Preset → NVIDIA Iray**
Reload the default Iray settings.
---
### 7. Rendering Through a Hidden Camera
Verify:
* The camera being rendered is the correct one.
* The camera isn't disabled or inside geometry.---
### 8. Emissive Objects Not Producing Light
If using emissive materials:
* Increase **Luminance**
* Check **Emission Temperature**
* Make sure the emissive surface is visible to the renderer---
### Fast Diagnostic Test
Create a new scene:
1. Add a primitive cube.
2. Add a camera.
3. Create a spotlight.
4. Render with Iray.If that renders correctly, the issue is specific to your original scene (lighting, camera, or render settings).
Can you tell me:
* Your DAZ Studio version?
* Whether the viewport is visible but the final render is black?
* Are you using an HDRI, lights, or only emissive materials?That will help narrow down the exact cause.
Aaaaah...found it...Points History. Ok. What about marking a product as a FAVOURITE so that you can decide later, especially if it's listed as a REQUEST?
Hi ZFX peeps. Thx for the opportunity in entering this art comp. I love a challenge and look forward to more. Congrats to everyone else who participated, we should all be inspired by each other. Thx also to the peeps who donated points. I was stocked to see 5000 points added to my account! So awesome. I love this site, it’s genuine and inclusive and given me motivation to get back into being creative.
Thank you 😊
AREVEEHi ZGFX Peeps, I'm a NOOB around here. I was working on a version of this female couple for another comp (with a little more pazzaz you might say!!) Anyway, without further ado may I present:
A. Good Times
