OpenVDB

The archive contains multiple folders, each with an animated .vdb sequence. These volumetric assets can be loaded into any 3D software that supports OpenVDB, offering high flexibility for creating realistic smoke effects.

• Optimized for Performance:
  The VDB sequences have been resampled to improve performance, making them suitable for a wide range of systems, including lower-end setups.

• Density Attribute Only:
  The files include a single density attribute for straightforward shading:

  • Use density to control the volumetric look.
  • Use remapped inverted density to define emission properties like brightness or color.

• Shading Tips:
  A color ramp is highly effective for adjusting density and emission inputs. For Blender users, the included shader presets are designed to save time and simplify the process of integrating and customizing these assets.

MOV Files

The archive also includes ProRes 4444 MOV files with native alpha channels, providing ready-to-use smoke animations for compositing or texturing in your 3D or 2D workflow.

• Why ProRes 4444 with Alpha Channels?
  These files include a pre-keyed alpha channel, ensuring clean integration into your scenes without the need for manual keying. This makes the smoke elements far easier to use compared to live-plate footage, which often requires intensive keying and cleanup to isolate effects.

• Benefits of CG Alpha Channels:

  • Perfectly pre-generated alpha masks ensure no spill, noise, or transparency issues.
  • Accurate edges with no artifacts, even in fine, wispy smoke details.
  • Consistent quality across all frames, saving time and ensuring a professional finish.

These MOV files are ideal for quick integration in post-production or for use as animated image textures in 3D environments, making them a versatile choice for creators seeking efficiency and quality.
