path tracing is slower, needs more ram and you have the noise/quality tradeoff.
it cant be that fast then reyes because like the name says, it renders only what the cam sees in the bucket which is currently rendering. it does not care about the things outside of the actual bucket. pt is completely different, takes alot more renderpower and solves slowly. but thanks to all the crazy amount of processing power which the big studios have they switch to pt or bidirectionel pt. it saves setup time, thats right, it renders more realistic out of the box with modern implemented shading models but the downside is the extrem long rendertimes and memory usage compared to reyes.
if you need fast renders with alot of dispmapping, mb and perhaps dof, then reyes could be a better choise when you dont need gi. but with point based color bleeding, which is really fast but not accurate as path tracing, you can also render with gi and, most important, noisefree.
noise is the big problem here for a path tracer, especially with alot of indirect light. bidirectionel path tracing can help alot in such cases. of course, all of this does not cover caustics, for this exists better methods.

Blob Strokes
Here's a small ICE compound used to generate these 'blob-strokes'. I had something
like this before, but I really wasn't so excited by the speed of generation. Now with
3delight, it's definitely feasible, updates are performed immediately. The compound
creates particles on curve list, evenly distributed, count is relative to particular
sub-curve length (still, you'll need to take care of curve re-parametrization). It's
also able to perform 'write on' on one-after-another subcurve (by sub-curve, or normalized
by sub-curve length). In short, you can 'draw' 3d strokes with it, by animating the
slider value. There are a few additional parameters. [..] contd. under si-community link

3Delight
v4.0.41 updated Feb 21st 2015. 3Delight is a fast, high quality, RenderMan®-compliant renderer designed to produce
photo-realistic images in demanding production environments. The renderer was introduced
to the public in the year 2000 after being used for more than a year as the sole renderer
in a sister production company. It is now widely used and earning a reputation as
a benchmark in rendering technology. [..] (cont'd on product page)
DNA research recently released the 4.0.41 upgrade along with making the free license now support up to 8-core CPUs. Highlights from the changelog: Volumetric Smoke and Shards Any shader as light source projection Exposure, Gamma Controls Mesh Light support ESC to stop render. Last year's big 4.0 update introduced features such as: support for deep EXR files Native MARI textures support Improved sampling of environment maps Added the physically plausible 3Delight Material "Continuous rendering" is now enabled by default Up to x2 acceleration in hair/fur rendering Memory usage is down 30% when using the path tracer Skin shader for 3Delight for Softimage Motion Map property is now supported
A list of movie project rendered with the 3Delight renderer. As mentioned the product is free of charge for the first 8-core license. Additional quad-core licenses are available for 400$ each and unlimited multi-core licenses for 900$ each. Yearly support and updates 190$/290$ resp.

Re: 3delight tests
Thanks kzin for your input.
However, are you talking about 3delight or raytracing vs reyes in general? If that's the case, I already know about the trade-offs when choosing one or the other and I was more interested to know if 3delight changes or brings something new regarding all these well-known facts.

Re: 3delight tests
I don't know, honestly. Tried some path tracers, but didn't used any of them for something serious. For now, simply there is no reason to do that.McNistor wrote: If that's the case, I already know about the trade-offs when choosing one or the other and I was more interested to know if 3delight changes or brings something new regarding all these well-known facts.
Re: 3delight tests
no, it does not. it has the same problems like arnold for example with some things arnold can handle better actually, like the clamp thing.McNistor wrote: more interested to know if 3delight changes or brings something new regarding all these well-known facts.
Re: 3delight tests
Ah, I see.
What clamp thing,
is it the equivalent of color clipping in Mentalray?

Re: 3delight tests
clamping values is needed for really high energy pixels which are hard to solve when only a small amount of pixels in the scene have this energy and reflecting on surfaces for example. you would need a hell lot of sample to sample such small areas and solve them. its easier and result and better solved images when you clamp suxch values to a max value.
in vray its the color mapping stuff, in arnold the clamp option and in mr together with mila shader the clamp string option.

Re: 3delight tests
hi there,
i try to learn 3delight in this tutorial(link below), but i have no luck .Anyone who already familiar with 3delight can help me do a simple start with it.
https://3delight.atlassian.net/wiki/dis ... +Softimage
what i want is how i can do like this guy in this movie. I don't know how to registy a shader

Thank for your attention!
