The Iray renders scene too SLOW ! , anybody knows how to improve the rendering process?  My video card is RTX2060 SUPER 16G mem but still too slow, I recall for Maya or 3dsMax it has a plugin to let you render remotely via google cloud computing.

Unfortunately, the RTX series don't have any advantage for iClone's Iray. A better card would actually be the GTX 1080 Ti (if you can find one). The Iray renderer does support multiple GPUs, so that is an option.

Thanks for the information, I will check it.  but I think RTX series is newer so I hope Iclone would support it in near future.

Do you want to render movie or still pictures ? if you want to make movie with Iray, forget it. untill now, I'm searching one, just one iclone movie rendered by iray, I've never seen. that says all . Iray is made for still pictures
