Re: Kray 2.0 RC1 released!

What are the Frost and RenderWorm pixel orders useful for? I mean, they look cool, they seem to work well... :mrgreen: But why were they added? What's their benefit?

What you can do is put a transparent polygon in front of the camera and used nodes to gamma adjust its transparency. This is only good for previews, though, and should be removed for the final render or else the antialiasing will be incorrect.

Just a word of warning that there are some G5 specific bugs with kray, which I cannot say whether they will be fixed in the GM version of 1.7. So my advise to anybody wishing to use Kray on the Mac would be to use a Intel Mac, as I cannot guarantee that Kray on a PPC machine will have parity with t...

Well, despite Captain Obvious' apparent difficult-to-impress nature (;)), in particular the T-Rex and the sci-fi greebles scenes seem pretty quick to me. The T-Rex is lit by one of the more contrasty HDR environments, and the sci-fi scene...well, I've been trying to render a somewhat similar scene o...

Would it be possible for Kray to be programmed do a photonmapping pass, then in areas with too low a photon density, do additional lightmap tracing to fill in?

That technique doesn't but here's one that does (and, depending on your goals, might work better): Set up the surface to be 0% transparent, 0.01% luminous. In the node editor, connect a Refraction node to Specular Shading. Add a KrayIndirectRays shader and put the Multiply value at 100 times your in...

A high N relative to photons means a smoother solution, but also one with potential light leaks and general lack of detail in shadow areas (light where it shouldn't be).

Learning from other scenes is a good starting point, but even Kray settings ought to be fine-tuned to your own scene. Lighting too you can learn from other scenes, but here's a tip. It might sound sarcastic or obvious, but here's the thing; to brighten a scene, add more light. Make your environment ...

Does it influence FG rays to target the skyportal as well, or just photons?

Just a theory: You might have thought it helped since you used very low numbers of photons and since they are shoot random from time to time, you got lucky after you turned on occlusion and rerendered the leak was gone. Precache blur might also increase problems with more leaks in corners so i usua...

Can't wait to get my hands on this... :)

I'm not really sure what the first render is supposed to be showing - as opposed to the skyportal render, there's not really any lighting to speak of; it looks more like ambient occlusion. Was it just a very inaccurate photon map?

Occlusionsettings in lw wount do anything in Kray. Setting paths=1 will tace care of lightleaks in corners. Well, when I was doing tests of this scene I was using paths = 2, and oversampling...and was getting a strange light leak until I turned on Occlusion in Render Globals. That was the only chan...

Looks to me like you have some light leaks on the wall with the window, and in the shelves...I'd guess it might help for you to make the photon map more accurate, and make sure you have Occlusion enabled in LightWave's Render Globals panel. What photon settings did you use?
