Hi, i tried to use it with green screen. My Problem is: if i place this filter after the chroma key, choma key is stop working (i see a black screen where the greenscreen is, even if i not change everything on the rgb filter). When i place it before, everything is fine, but then it will stop working if i play with rgb, because greenscreencolor is changed too. Can i fix this somehow?

Okay, I made some changes to the filter. Add the RGB tool filter after the Chromakey filter on your foreground source. It should no longer affect the green screen color or the background.

Let me know if it now works for you correctly and I'll update my resource page.

This tool is an absolute must-have for color correction in OBS—awesome controls!

The design is incredibly intuitive, making color correction a breeze. The three RGB vertical bars are a genius feature. When they turn gray, you know the color balance is perfect—such a simple yet effective way to achieve white balance.

I can't wait to see what other tools you develop. You're making a huge impact in the OBS color correction world, and I appreciate it!

One feature I'd love to see added to the RGB adjustment tool is a color picker, in association with a skin tones adjuster - would be fantastic! I imagine isolating skin tone colors from an image and having a vectorscope-like tool with a skin tone line to help adjust colors precisely to match that line. :)

The filter uses an average of about 20 pixels around the crosshair. If the color bars are jumping a lot before turning on the WB lock, it means your image is fairly noisy, and after the lock is engaged, the whole image may "flicker" as it adjusts the RGB values to keep the pixels (average of 20) under the crosshair white.

I'll look into adding a sensitivity control for the WB lock.
