Re: Emitter not lit up

Ok, thats interesting, thanks. I'm still confused though! How does one go about changing luminous flux etc? The only emitter options in SKIndigo appears to be emission scale - increasing this doesn't resolve the issue. Glare should definitely add a way to scale the IES emission. It seems it only wo...

Re: Emitter not lit up

The IES profile sets the total amount of light emitted by the object in lumen. If you scale the source by 4x, its area is multiplied by 16. The lumen value being constant, it has to emit 16x less light per area unit. Which means the source surface appears 16x less bright. Since it looks like you hav...

Re: Lotus Elise

Whoa, impressive stuff!! The paint material is too reflective (if you used a phong material, that's the ior, what did you set?). This causes a strong color shift on the sky reflections towards blue which mixes as purple with the red and looks unrealistic. On a less important level, the ground materi...

Very nice, especially the second one!

I am missing the tree's shadows on the floor, though.

Cheers!

Re: Is it Possible to Create a Rainbow Arch

The artefacts in the bottom of the images show that you have reached floating point precision limit. In that case, the rays cannot be calculated accurately inside the spheres. This will clearly be a limitation

Re: Is it Possible to Create a Rainbow Arch

You need the refractive index of water, and the cauchy b coef of water. You need a sun not too high above the horison, and look towards the water droplets with the sun in your back. You also need a large FOV (at least 80° horizontally, which means a 18mm focal length on a 35mm film camera.

Using a high LMP value this low frequency noise gets way less!! Give it a try ;)
Yes, but I feel you also loose the efficiency of MLT. Is MLT with LMP=1 really more efficient than non-MLT?

Re: Help with difficult indoor lighting

Subliminal messages to the devs : there is often a problem with noisy glass when the camera side is well lit (such as exterior, or in this case), and the back side is more in the shadow (such as interior). The importance sampling, I suppose, will highly favor transmission, whereas the contribution o...

MLT is generally a bad idea for videos, the low frequency noise make it flicker a lot.

For the elevator glass issue, one solution would be increasing the glass reflectivity (refractive index) but this changes the final result and you may not want it. The problem is transparency.

Re: [REQ] More color spaces: AdobeRGB, Rec.2020, WideGamut e

Exactly. But the most quality monitors on the market cover 99.9% of sRGB...that should be plenty. Other than that sRGB is measured in P3 for 4K and up displays. I think the bottom line is ( correct me if i'm wrong ) that as long as you can pull a 32bit linear color spaced image format from Indigo y...
