Hi Guy's, I thought I would post a video I just made using the Arnold renderer in Solaris, the scene is very sparse and clean, only two objects, the sphere and the grid, the grid has the Shadow Matte material on it (from Arnold) and the Sphere has a chrome material, the Dome light has a hdri on it (blue_lagoon_8k.hdr) which you can get on line for free, there are no tricks or gimmicks here, the scene just works and it is fast on my two 2080ti's, I had to turn off the default denoiser in the render settings, that is all.
If Arnold can do this, why the hell can't Karma...

Hi Ron,I am running Houdini 20.5.400 in Rocky Linux 8.10 and it is extremely stable with everything I have thrown at it, but the back and forth stuff that is going on with the cop net seems to be too much, I haven't put in an RFE, but do it if you can.

Hey Ron, the first scene background_plate_example_v02.hip doesn't crash Houdini only the last one.

"Just out of curiosity: are you rendering the domelight-background with the shadow and the rest of the scene in one go and this is your final result or is this just for preview purposes and better context? "

Yes, I am rendering the domelight background with the shadows and the rest of the scene, I use this in low rez for preview, then when happy I crank up the rez to 4k and render, it is very fast, I have created a .hda which uses 7xMask by feature nodes, a light emitting grid, an envlight, a shadow catcher grid and a material which takes the Masks and applies them to the shadow catcher grid to create its transparency.
This works very well and fast, but it's not a proper Shadow Matte material as what other renderers use.
