• Verify the material's orientation and make adjustments if needed within Material Lab
• Try recalculating the material mapping with Auto UV

Lighting and Colors Look Incorrect

Symptom

Your render may:

• Appear darker or brighter than expected.
• Have an unexpected color tint.
• Look like a filter has been applied.
• Have unrealistic shadows or lighting.

Recommended Solution

Try the following adjustments, then re-render the image to see if the issue is resolved:

• Start with Neutral Settings.
• Reset Post Processing by selecting the Reset button.
• Try turning off ToneMap under Advanced > Post Processing > Color or make minor adjustments to fields in this value.
• Use Natural light render mode under Advanced or Product Lighting or Realistic in Simple mode.
• Verify the lighting setup.
  • If using Light Groups, please note that it splits the setting between all fixtures in a group rather than applying that setting to each individual light. E.g, If there are 10 lights in a group with brightness set to 1000 lm, each light will be 100 lm.

Shadows Do Not Appear in Render

Symptom

Objects in the drawing do not cast shadows, even though shadows are enabled in the view.

Recommended Solution

Try the following adjustments, then re-render the image to see if the issue is resolved:

• Verify that a floor has been enabled for the drawing. 
• If a floor is present,  check the elevation of the symbol and ensure its set to zero.
• Ensure that the Shadows setting under Render Quality > Advanced Settings isn't set to zero.

Transparent or Clear Symbols Render Invisible

Symptom

Transparent or glass materials appear completely invisible in the rendering, even though they are visible in the 3D view.

Recommended Solution

Try the following adjustments, then re-render the image to see if the issue is resolved:

• Ensure that the Transparencies setting under Render Quality > Advanced Settings isn't set to zero.
• If you're using a custom material, open Material Lab and verify that the material's Opacity is set appropriately. Increase the opacity if necessary.

Renderings are Slow

Symptom

Renderings take much longer than expected.

Recommended Solution

• Reduce the rendered area by using 3D Clipping. Please note that 1 type of clipping (isolate or hide) can be used at a time.
• Lower the render quality under Photo Lab > Advanced > Render Quality.
• Lower the image dimension settings under Photo Lab > Advanced > Image Dimensions. The 720P setting works great for presentation. 
• If using a ceiling in the drawing, enable Use Area Light in Quick Properties for the ceiling.
