thats cool Daniel!

[SonOfNimrod]

wow those caustics look great!

[DaForce]

wow.. that is pretty damn cool.

[aaron-cds]

Those are great. I really like your car photographs on your website as well, especially the b/w ones. Very nice.

[jonnybefree]

thats caustics!

[ene.xis]

gr8 stuff buck!

[Dark_Arkon]

really gret the maxsrcript command. It will be cool that you add a button to activate it. It's much easier to tweak caustics.

Is it just me, or the directly traced caustics is clamped in newer builds? I used to use this feature a lot. I know it's not "supported" yet, I'm just curious.

I just can't stress enough how important this feature addition was. Hawing perfectly crisp caustics fast without the struggle of setup, and without any significant memory footprint, well, even if refracted/reflected not supported... it is awesome. period.

I don't think it has changed in newer builds at all - it was working fine last time I checked.

Hmm, I thought so, maybe I'm doing something wrong. I doubt it has anything to do with the fat that I'm not in office, and here I'm using the sp1 demo version.

By the way, I just wanted to ask this, and it's related to caustics: I can get pretty nice caustics with LC + Bruteforce, and from diffuse light sources the effect clears up pretty fast wit fewer subdivs also, but I was wondering if a precalculated caustics map could be used to speed up the bruteforce sampling to get clearer caustics for specular situations, just like once the global photon map was used to guide the diffuse GI.

Yes, in general it is possible to do that (you can also use the Adaptive mode of the light cache), but it still is a bit of a hit-and-miss thing.

A bit of a hit and miss, hmm. I'm not an expert on this, but I always thought of a photon map pass as an "importance map" to determine hotspots for backward tracing, so when I first tried VRay, and switched on caustics photon map with qmc as the main GI, I was expecting it to behave like that. Long before the bidirectional path tracing hype.

Best regards,

I'm sure brazil works like that.

P.S. I love this caustics previz, to see how it should be. And then to tweak settings for scene. It is a lot faster to set the correct settings (of course with max density >0).

[khoross]

cant seem to make it work in sp2.
is this option still exist or im i doing something wrong ???

[Paul Oblomov]

It still works.
