dm_Despill (Compatible with IFFS 2017.0.0 and up)
dm_Despill — Despill shader for Autodesk Flame. Six algorithms, custom colour picker, IBK-style weighted average, spill area correction and spill matte output. Inspired by DespillMadness (Andreas Frickinger, Nukepedia 2010) and the IBKGizmo weighted despill approach.
Version notes
A Matchbox despill shader for Autodesk Flame. Six algorithms, a custom colour picker, IBK-style weighted controls and spill matte output — all in one node.
How it works
dm_Despill computes a limit for the spill channel based on the surrounding channels, then clamps any excess down to that value. Six algorithms control how that limit is calculated — from a simple average to fully weighted per-channel control.
A custom colour picker lets you sample any screen colour directly instead of choosing between pure green, blue or red, with the shader automatically deriving the correct channel weights from your pick.
Fine Tune scales the limit ±15% for subtle adjustments. Spill Area Correction (saturation, gamma, offset, luminance restore) lets you grade the despilled area to match the plate. Spill Matte in Alpha outputs exactly where the despill was applied, ready to drive downstream operations.

Something wrong with this page or the download?
Contact the site custodians via email, if:
- This shader is obviously incomplete (missing files, not loading) etc.
- This shader violates IP rules (is pirated) or contains harmful content
- You are having problems with the shader installer (INSTALL.command) or the download.
How to get help with this particular shader
Sadly, the custodians likely will not be able to explain to you how a shader works or debug its code, or fix it for you. That is the (volountary) role of the shader author.
If the shader does not work on your system or you have questions about it - read the shader description, and try to find the email address of the shader author. Contact them for any issues – letting them know whether you are on Mac or Linux, what version of IFFS you are running etc. will likely help. Be kind and respectful. If you can't get hold of the author - you can try asking in the Logik forum at logik.tv and ask whether anyone could help you debug a particular shader not working.
