Senior moment major bug fix. When I'm working on filter script code, I use a separate shader file. The LUA script loads this shader file to use it. Usually, when I'm ready to submit the filter to the OBS forum, I will copy and paste the shader code from the external file into the LUA script and change the reference from the external file to the pasted code. DOH!!! I forgot to do this in version 1.5.
If you downloaded version 1.5, delete it and download and install version 1.6.
Fix a bug when the filter is applied to a video capture source set to deactivate when not shown. If the video capture source was cropped, the bug prevented the source from displaying when it was reactivated.
