So products I interested in Reallusion are CC3, headshot, iCone, and Iray plug in. My questions are 1. how's iRay plug in works in CC3? how often does it fail?
Not really sure what you mean by "Fail". In my experience it really never fails to render but you can run into problems if you are using objects that are not compatible. For example PopcornFX particles are not compatible with Iray so you may have to make adjustments to your scene before rendering to get the best output.
2. how large of a scene I can expect to create with these tools if my primary focus are on 3D art, 3D comic(single frame render), animated short clips. For example, would 5 characters on 1 scene at once with high poly building, high res texture terrain and dome too much for my i7-5820, 16G and RTX2060?
Again a very difficult question to give a precise answer to. You mention 5 characters but it will depend on the poly count of the characters plus clothing and the textures you are using. For example, using 4K textures will place big demands on your computer. Using lower res textures will help improve performance. Also the number of props and the resolution of textures used will also have a big impact on performance.
Really the biggest factor will be your available video memory. So a great way to keep check is to turn on the Info display (CTRL+F) and monitor your Video Memory. When it exceeds what you have onboard your graphics card performance is going to start to suffer and you may need to make compromises.
I personally find it is best to work with several smaller projects rather than trying to have everything in one big project.
Iray in Daz in 4.12 always has problem to tackle the GPU resource for its IRAY render and would attack CPU with the first chance it got, but when you disable CPU as a fallback option, you will get a blank or black screen when rendering, the same issue reported by numerous DAZ users, many topics opened, many tickets raised, no answer from DAZ's dev team. Imaging you spend hours putting up a scene, tweaked your lighting and place your local lights in the perfect position, looks perfect in iray preview, then when you use the render, everything fall apart, I doubt it's the Vram issue, because when you allow render renders on CPU, everything will work, maybe slow, but surely, and it reduce my PC's lifespan along the way. And since all modern GPUs are multiply times faster than CPU, if the render engine doesn't tackle the GPU resource properly, I seems like a poor coding/optimization effort than anything else. But the lack of debugging tool and support effort from DAZ really discouraged me from continue using their tool.
By now I noticed that there's a free trail option on most reallusion products, really enjoyed CC3, and it seems like Iclone will allow me to do most stuff I did in DAZ and then some, so I'm planning to switch, still trying to understand the difference between the product package plans.
