hey guys i am new to corona render and i love this render engine after coming from vray, but right now the only thing that seems to be broken is the caustics solver for any scene I use no matter what it is. The problem with the caustics solver is that it takes double the time to render but not only that it produces splotches and fireless all over the image that will not go away no matter with many passes (100+) especially with curved shiny metal. As soon as i just uncheck the caustics solver the images come out perfect with no noise difference per frame for animations which is one of the major problems with the caustics solver it produces a different noise pattern from frame to frame even when using the flicker free UHD cache setting and using lock noise pattern and using many passes and I am using the HQ denoiser not even the AI denoisers and it still flickers I even tried using the path tracing unbiased engine for the secondary solver and still does not work and the noise is still different and still does not go away with 100+ passes. if I turn off the caustics solver all of a sudden my images are noise free with no flicker at half the render time. Please fix this caustics solver problems in final version 6 release. I am using version 5 hotfix 1 with 3ds max 2021 by the way and i am using this scene which can be purchased at this link:
