CreateBumpMap
Height map to bump data
Converts image-based height information into bump or normal-style surface detail for 3D material shading.
CreateBumpMap
DaVinci Resolve · Fusion
Converts image-based height information into bump or normal-style surface detail for 3D material shading.
Overview
What CreateBumpMap does
Converts image-based height information into bump or normal-style surface detail for 3D material shading.
Mental model
The image does not move vertices; it creates virtual surface slopes that change how light reacts.
Common uses
Create bump detail from grayscale maps
Add scratches or embossed patterns
Convert procedural noise into bump information
Prepare maps for material shading
Flow anatomy
Inputs & outputs
The port structure shows how this node fits into a Fusion graph.
Image
Source data used to create or modify the material, texture or mapping result.
CreateBumpMap
Fusion node
Image
Processed texture, mapping or material data for the next 3D shading stage.
Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Height Channel
Selects the image channel used by this operation.
Clamp Normal.Z
Clamps values to the allowed range instead of letting them continue beyond it.
Wrap Mode
Selects the Wrap Mode used by CreateBumpMap.
Height Scale
Sets the vertical size.
Texture Depth
Sets how strongly source texture values are converted into bump depth.
Practical setup
A reliable workflow
- 1
Prepare the source image, texture, material or mesh that CreateBumpMap will use.
- 2
Insert CreateBumpMap at the stage where mapping or shading should change.
- 3
Use a simple test material or checker pattern while tuning CreateBumpMap.
- 4
Verify scale, orientation and color/alpha interpretation before judging CreateBumpMap.
- 5
Render CreateBumpMap under a neutral test light before adding final look development.

Material workflow
CreateBumpMap prepares or modifies a material-related branch before rendering.

Reusable texture setup
CreateBumpMap stays isolated so the same mapping or texture can be reused.

Troubleshooting
Common mistakes
Changing several CreateBumpMap parameters at once and losing track of which control caused the result.
Approving CreateBumpMap from a single still frame without checking motion or representative lighting.
Adding extra controls around CreateBumpMap before the basic source, transform and render path is known to work.
Production notes
Practical tips
Name CreateBumpMap by purpose when a composition contains several instances.
Use a lightweight preview while tuning CreateBumpMap; restore the intended quality settings before the final render.
