How to Accurately Identify the Last Rendering Mode

[394452216@qq.com]

Hello I want to know whether the content of the last rendering in the current VFB was generated by Production Render or IR Mode. There is no time record in the log （CoronaMax2026_log.txt， CoronaMax2026_interactive.txt）, so it is impossible to tell.
CoronaRenderer.CoronaFp.getRenderType also only works during rendering. It will not function once rendering is complete.
