Re: fireflies with IBL lighting and metal/glass surfaces

Here are two (from the same render). Shiny gold earrings. The rest of the render was quite "done".

fireflies with IBL lighting and metal/glass surfaces

Generally I get good results using IBL lighting and Reality. One limitation is that I tend to get what I think are fireflies on skin (e.g. G3F) near metallic jewelry or shiny objects like sunglasses. I think they are fireflies because they get worse with rendering time, not better. Any suggestions i...

Re: Genesis 8

I wonder if G3F will be the V4.2 of her day, and if we won't get a truly improved figure till about V10 or so...

Re: antialias

Thanks. I do see this more with harsh lighting, like the reality sun. The G3F figure I use has already been subdivided in DazStudio, which I believe transfers to Reality.

antialias

Not quite sure if this belongs here or in the troubleshooting forum... It's not always an issue, but sometimes skin edges and hair details render quite jagged in Reality/Luxrender. Is there anything in particular I can do to avoid this? In DS, my video card does seem to support hardware AA, but I as...

Re: Shadowcatcher in Reality?

I see, so it's a limitation of Luxrender. I will look into the panorama screen you mention.

Re: Shadowcatcher in Reality?

How about Reality supporting scaling, x- or z-rotation, or translations of the ibl sphere? That would be soooo handy.

Re: Will the latest version of Reality work with 4.8 and 4.9?

I have a question about this too. I've been using 4.8 since it came out, and have learned to deal with the way it loads textures/shaders and what happens to those when I call Reality 4. I'm worried that if I update to DS 4.9 I will have to start again if it interprets material files differently than...

Top coat and automatic presets

I regularly use top coat with a tan color and thin setting (like 0.1 nm) to slightly darken skin (e.g., for g3f). It seems like to the top coat flag and settings are not used when applying automatic presets, so I often have to turn these back on by hand. Is this a feature or a bug? Also, I see that ...

Re: [Advice Needed] Good Setting for Teeth

Real teeth are a bit translucent. I don't usually attempt to recreate that, but I do use a very high glossy strength (close to 10000) and spec color more like 70,70,70 because teeth are typically wet and shiny!
