Usage

Access RenderForgeAI via the RenderForgeAI tab in the 3D Viewport sidebar (press N). The addon is organized into sections for intuitive control.

1. HDRI Generation

• Purpose: Generates procedural HDRIs to enhance scene lighting and reflections.

• Steps:

• In the HDRI Generation section, check Enable HDRI Generation.

• Select an HDRI Style (Natural, Urban, Studio, Sunset, Overcast).

• Click Generate HDRI to update the world shader.

• Result:

• Sunset: Creates a gradient sky (orange to purple) using a ColorRamp.

• Natural/Other Styles: Uses Nishita or Hosek-Wilkie sky textures.

• Inspect the world node tree in Shader Editor (World context).

• Tips:

• Use glossy or metallic materials to visualize HDRI reflections.

• Adjust Strength in World Properties > Background node for intensity control.

• Combine with Scene Analysis for style-specific HDRIs (e.g., Realistic preset uses Natural HDRI).

2. Intelligent Denoising

• Purpose: Reduces render noise using OpenImageDenoise, enabling high-quality results with low sample counts.

• Steps:

• In the Denoising section, check Enable AI Denoiser.

• Choose Denoise Quality:

• Fast: Minimal smoothing, fastest.

• Quality: Balanced noise reduction.

• Ultra: Detail-preserving with normal passes.

• Adjust Denoise Strength (0.0–1.0, default: 0.5).

• Click Denoise Render to apply settings.

• Result:

• Render settings update in Render Properties > Sampling > Denoising.

• Low-sample renders (e.g., 16–32 samples) appear smooth.

• Tips:

• Use Ultra for complex scenes with fine textures.

• Lower Denoise Strength to preserve details if over-smoothing occurs.

• Combine with Render Optimization for automatic denoising in quick renders.

3. Scene Analysis

• Purpose: Analyzes scene geometry, materials, and lights to provide insights and lighting suggestions.

• Steps:

• In the Scene Analysis section, click Analyze Scene.

• Wait ~3 seconds for a loading animation (orange bounding box in Viewport).

• View the Scene Analysis Results popup with metrics:

• Object count, bounding box size.

• Material count, average roughness.

• Light and camera details.

• Lighting issues (e.g., overlapping lights, high-energy sun).

• Apply a suggested preset (e.g., Apply Cinematic) from the popup.

• Result:

• Lights are added to the scene (e.g., AI_Cinematic_1, AI_Cinematic_2).

• World shader may update (e.g., HDRI for Realistic preset).

• Action Log records analysis (e.g., Analyzed 50 objects).

• Tips:

• Use for large scenes (>10K vertices) to identify optimization opportunities.

• Check Action Log for detailed feedback.

4. Lighting Optimization

• Purpose: Applies AI-driven lighting setups tailored to scene content and artistic style.

• Steps:

• In the Lighting Optimization section, check Enable Light Optimization.

• Select a Lighting Preset (Realistic, Cinematic, Studio, Dramatic, Soft Portrait, Product).

• Choose a Lighting Style (Realistic, Cartoonish, Oldie).

• Adjust Lighting Intensity (0.1–5.0, default: 1.0) and Color Temperature (1000K–10000K, default: 5500K).

• Click Optimize Lighting or Analyze & Suggest Lighting for style-based suggestions.

• Result:

• Lights are added (e.g., AI_Realistic_Sun, AI_Studio_1) with scene-specific positions and properties.

• Existing AI lights are cleared before applying new setups.

• Action Log confirms application (e.g., Applied cinematic lighting with 2 lights).

• Tips:

• Use Scene Analysis first to ensure accurate light placement.

• Experiment with styles for creative effects (e.g., Cartoonish for vibrant colors).

5. Volumetric Effects

• Purpose: Adds atmospheric effects like fog or haze to enhance scene depth.

• Steps:

• In the Volumetrics section, check Enable Volumetrics.

• Adjust Volumetric Density (0.0–1.0, default: 0.5).

• Click Setup Volumetrics to add a volume scatter node to the world shader.

• Result:

• Renders show atmospheric effects (e.g., light scattering in fog).

• Check Shader Editor (World context) for the Volume Scatter node.

• Tips:

• Increase density for thicker fog; decrease for subtle haze.

• Combine with strong lighting (e.g., Dramatic preset) for visible effects.

6. Render Optimization

• Purpose: Optimizes Cycles settings for faster renders without sacrificing quality.

• Steps:

• In the Render Optimization section, check Enable Smart Render.

• Set Target Render Time (10–3600 seconds, default: 60).

• Enable Adaptive Sampling for dynamic sample allocation.

• Click Optimize Render to apply settings.

• Result:

• Render settings adjust (e.g., 128 samples for <120s, denoising enabled for <60s).

• Action Log confirms optimization (e.g., Optimized render settings: 128 samples).

• Tips:

• Use for quick previews or final renders with tight deadlines.

• Combine with denoising for low-sample, high-quality results.

7. Quadify Premium Integration

• Purpose: Optimizes meshes to reduce polygon counts, improve UVs, and enhance render performance.

• Steps:

• Ensure Quadify Premium is enabled (automatically included with RenderForgeAI).

• Select a mesh object in the 3D Viewport.

• In the RenderForgeAI panel, locate the Quadify Premium section (if exposed in UI) or access via context menu (right-click object > Quadify Optimize).

• Configure settings (if available):

• Decimation Ratio: Reduce polygon count (e.g., 0.5 for 50% reduction).

• UV Preservation: Maintain UV maps during optimization.

• Topology Cleanup: Remove degenerate geometry.

• Run the optimization operator (e.g., Optimize Mesh).

• Result:

• Mesh polygon count decreases, improving render times.

• UVs and materials remain intact (if configured).

• Action Log records optimization (e.g., Optimized mesh 'Cube' with Quadify).

• Tips:

• Apply to high-poly models (>100K vertices) before rendering.

• Test with Scene Analysis to verify performance gains.

• Check Object Data Properties for updated vertex/polygon counts.

8. Action Log

• Purpose: Tracks all addon operations for debugging and user feedback.

• Steps:

• View the Action Log panel below AI Light Enhancer.

• Monitor logs during operations (e.g., Generated sunset HDRI, Applied denoising with ultra quality).

• Tips:

• Copy logs for support requests.

• Clear logs by restarting Blender if needed.

Example Scene

The included demo_scene.blend file demonstrates all RenderForgeAI features:

• Contents:

• Objects: Cube, sphere, plane with glossy, metallic, and diffuse materials.

• Camera: Positioned to frame the scene.

• Lighting: Basic setup for testing presets.

• Test Workflow:

• Open demo_scene.blend in Blender 4.4.

• Go to RenderForgeAI tab.

• Run Analyze Scene and apply the Realistic preset.

• Generate a Sunset HDRI.

• Enable Ultra denoising and set samples to 16 (Render Properties).

• Optimize a mesh (e.g., sphere) with Quadify Premium.

• Add volumetrics with density 0.3.

• Expected Result:

• Glossy objects reflect the HDRI.

• Render is noise-free despite low samples.

• Mesh optimization reduces polygon count.

• Action Log records all steps.

Troubleshooting

• HDRI Not Visible:

• Ensure Cycles is the render engine (Eevee may not show reflections).

• Check World Properties > Use Nodes.

• Verify Enable HDRI Generation is checked.

• Run bpy.ops.ai.generate_hdri() in the Python console and check for errors.

• Denoising Too Blurry:

• Reduce Denoise Strength (e.g., to 0.3).

• Switch to Ultra mode for better detail preservation.

• Increase samples (e.g., 64).

• Lighting Not Applied:

• Ensure Enable Light Optimization is checked.

• Run Analyze Scene first for accurate placement.

• Check Action Log for errors (e.g., Invalid context in OptimizeLighting).

• Volumetrics Not Visible:

• Increase Volumetric Density or add strong lighting.

• Verify Volume Scatter node in Shader Editor (World context).

• Quadify Optimization Fails:

• Ensure the selected object is a mesh.

• Check Action Log for Quadify-specific errors.

• Verify quadify_premium.py is present in the addon folder.

• General Errors:

• Open System Console (Window > Toggle System Console on Windows).

• Run operators in the Python console (e.g., bpy.ops.ai.denoise_render()) and note errors.

• Share Action Log, console output, and scene details with support.

• Performance Issues:

• Enable GPU rendering (Preferences > System).

• Optimize meshes with Quadify Premium for large scenes.

• Use Fast denoising for quick tests.
