Re: Point-Based Rendering

It's an interesting method, but basically not at all relevant for Kray. Kray is more efficient at ray tracing than it is at handling large datasets. It would make more sense to improve things like irradiance caching.

Re: Cityscape 'St James' animation

We did an edit that I feel was nicely paced, but they ended up re-editing it (without even having access to the original clips — they just cut and pasted stuff directly from the edit we did...). I don't like their version so much, and the graphics and general presentation I think are a bit... yeah, ...

Cityscape 'St James' animation

Here is an animation that I produced at Cityscape. Editing and graphics was done by someone else. Please watch it without audio, as the music is, in my humble opinion, terrible. http://www.youtube.com/watch?v=XChH2QKEE3M Main renders are done in Kray, volumetric effects and misc stuff in LW render. ...

Re: Inverse Square Law for Lumipolys

Basically, because luminous geometry are not LIGHTS, as such. Imagine if the moon was twice as close to the earth! It would appear four times bigger, and even though the surface would appear to be the same intensity, the increased size means that four times more light would reach you -- the total in...

Which would then be a custom shader where the intensity varies based on the length of the incoming ray. :)

Re: Inverse Square Law for Lumipolys

As I posted in the other thread...


Luminous geometry ALWAYS has inverse square falloff. You can change this with nodes, though: use the spot info's 'ray length' or whatever it's called, plug it into a gradient or something.

Re: bath room

Luminous geometry ALWAYS has inverse square falloff, and you can't do anything about it unless you give the light a custom shader where the intensity varies based on the length of the incoming ray.

Re: Butterfly / Kray problem when split frame?

It's not necessary to generate the full-quality GI solution on just one machine, though! Set it do to a full render, but without AA and at 10 % resolution. This will greatly speed up the generation of the GI cache, and once you have a 'baseline' to work from, the nodes will generate results that are...

Re: Reducing noise

There's no gi in the scene. Just raytracing. I used kray because the raytracing is faster than lw renderer by almost 3 times :mrgreen: I could get rid of the noise in lw renderer if I use enhanced medium. Is there equivalent setting in kray for enhanced medium? Use Lightwave's Perspective camera in...

There are several ways to get FPrime to do tone mapping: - You can render out normally and then tonemap in Photoshop or some such. Image -> Adjustment -> Exposure, set the Gamma to 2.2. - Or you can turn OFF the gamma for your monitor. This is a bit more work, though. - Or you can use my node-based ...

This is largely because of gamma correction.

Did you do BORDERLESS limited region? Because if it crashes anyway, it's not related to the resolution.

Do a bunch of borderless limited regions. It'll work fine.
