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

No, camera response functions are not related to color spaces.

The colors that are outside the sRGB gamut are lost when saving in an sRGB color space image and there is no way you can recover that in post. Many professionals need wide gamut color spaces.

Re: Emission for mesh

That's a very classical question that should be covered by the FAQ.

You are likely using Reinhard tonemapping, which adjust the "lightness" gain automatically to the image. You need to switch to linear tonemapping to see the changes.

Re: CPU Thread count

It actually does help. 3dsmax for instance is much more responsive when leaving a few threads free, that's a matter of fact!

Re: access meanCurvature() within a blend shader

Well, I just tested, and ... it does not work. I think it worked once, but I'm not sure.

Re: access meanCurvature() within a blend shader

First, the curvature is signed. Which means the sign changes between concave and convex surfaces Also, the unit is 1/m, and the value is the reciprocal of the curvature radius. This means that if your surface has features of a few mm, with similar curvature radius, the curvature value will be around...

Re: [ISL] I board failed to do polka dots

Also, in order for bump to work, you need a smooth transition between "high" values and "values". A brutal, vertical transition does not work well with bump, because bump is actually based on slope, not height.

Re: Old masters of Murano-Venice

If your scene is too big or too large, you can simulate a scene rescale by multiplying focal length and sensor witdth by the same amount. Example : if you have a scene which is in kilometers, but want to have DOF, you need to have a very big sensor size and a very big focal length. And conversely : ...

You can actually get a very similar effect with a shader, using world coordinates to lookup in the texture. That's not super convenient though.

Re: Rotation vs scale

1) Sometimes, the UV matrix is of great help for last minute texture scale adjustment without having to reexport everything. 2) I have a client case where an architectural scene is tested with various floor materials. The various materials have textures which have different scales. Using UV matrix, ...

You are talking about dynamic range, gamut is a different thing. Cameras have a low dynamic range, so you take multiple shots so that you can interpolate the full dynamic range.

Re: [REQ] v4 video functionality

Hi Thanks for your kind response. In truth I suspect that may be made of the earlier tests. In essence it is preferable to halt spp vs halt time, right? This depends on your constraints. If you have 48h to render 4 images, set your halt time to 12h. The main advantage of halt spp is, the quality wi...
