Hi everyone, I need to convert an old C4D file, it was done in 2013 and R25 do not read it. Probably anyone using R19 can open it and resave the file to be readable by newer version. You can keep the model;) https://www.dropbox.com/s/rhucepw6n0u797d/fontana padiglione.c4d?dl=0

Messing with scene size is not an ideal solution since it may introduce many other problems. We have the same issue in Vray but there is an easy fix for that, here we just need to decrease the shadow bias in the light, maybe there is something similar in RS too.

Thanks, I'll try in the afternoon;)

Thanks for the tips, how can I do that?

I'm getting closer to what I'm looking for, I'm still not there yet;) A few more questions.. -what kind of geometry do nodes generate? is it something like simple instance or render/multi instances? I ask because I need to generate a lot of clones over the surface (probably close to a million) and without render instances it will be a no go. -Is there a way to display the clones as a point instead of the full geometry when using nodes? -Is it possible to randomize the distribution (rotation and scale) of the clones using this system? Sorry for the many question but is the very first time that I'm looking in to the nodes:)

Thanks a lot!

Yes that's what I need, can you post a basic example? Thanks, I tried this solution but is not perfect for my setup;)

Is there a way to force a minimum distance between clones while using a cloner in object mode?

I can render 10 million grains even on a 32GB system using multi instances, preparation time was a couple minutes. You should be able to render as many grain as you want as long as you have enough RAM, you should expect longer preparation time the more grain you add though. Of course you need to keep the grains visible only when rendering because the viewport won't display millions of individual objects.

Here is another test: Also easy to animate: https://www.dropbox.com/s/35t6ueby8aee1p9/zen test4.mp4?dl=0 The only downside is that you need to load the splines manually but I'm sure someone more capable than me will be able to automate the process, once you automate the spline thing you can create a full zen garden in no time.

Sure here it is: https://www.dropbox.com/s/91bkqkq49zmw49s/zen.zip?dl=0 I've done some modify on the previous file to get better results in the viewport, you will find also a basic "glitter" effect. Here is a quick video done using the viewport renderer: https://www.dropbox.com/s/6hruaseha7duppp/zen test3.mp4?dl=0

Maybe I'm missing something, but it seem to be very simple to get similar results using a spline modifier and some basic geometry:

Not a contributor but here you can find some info: https://www.chaos.com/blog/the-render-tricks-behind-netflixs-nsfw-love-death-robots https://www.fxguide.com/quicktakes/love-death-robots-in-v-ray/ The series has always intrigued me but I have never had the chance to see it..

It is not only lack of moderation and other mentioned stuff, CGtalk (in specific the C4D forum) died also for other important reasons. Years ago it was a nice community full of helpful users ready to share their knowledge. In latest years it became a forum where a few people start to go systematically off topic, posting regularly only thread (like C4D VS Blender, C4D VS Modo, C4D VS the flavor of the month, Mac VS PC, and countless other toxic threads). People simply started to look elsewhere, somewhere thay can find informations and a nice constructive community. It take only a few bad user to let a forum die, I've seen this many time (also on non 3D forums), and it would be nice if Core4d forum didn't end up in the same way. Of course I'm again censorship in general, that being said I do not find "healthy" (just my very personal point of view) to post on C4D forums mainly stuff related to other softwares. I mean.. from time to time it is good to know where the competitors are, but if suddenly a C4D forum become the place to discuss mostly other stuff, then there is something wrong. I'm pretty sure that if I go on other software forums (Max, Blender, Maya, Modo or whatever) to start to post regularly C4D stuff, I'll be quickly labeled as a troll, crazy, or similar. It is pretty simple for me, if I need info about a specific software (let's say Blender since it is "the flavor of the month") I'll go to a Blender forum, that will be surely full of people expert in that particular software, if I visit a C4D forum I expect to find mostly C4D related stuff. Then there are the "angry" topics (I'm not referring to anyone in particular 🙂 ), another reason why CG Talk forum died. Again.. this is my very personal opinion... if I'm not happy with a software feature set, price, or whatever, I simply express my disappointment with my money. If a software suddenly do not fit my needs anymore then my money go elsewhere. Wining on forums is mostly pointless, it doesn't solve anything... maybe somebody may feel better knowing about other angry people sharing the same opinion, but it still do not solve anything.. Large companies do not care about disappointed users as long as their incomes are intact, but you can be sure that when they will see their money go elsewhere, then they will listen 😉

I assume RS have some form of volumetric effect for fog and similar, try to activate it and probably you will get volumetric caustics;) I uploaded a video on YouTube, when the laser beam hit the corner the light get diffracted in many different ways, so a few frames would have needed much more photons.

As said any renderer that supports volumetric caustics and dispersion should be able to do that, no need for spectral renderer 😉 Even biased renderer can produce that effect, this was done many years ago on an old version of Vray using the biased engine and it's pretty accurate, this is the scientific test I've used for reference: https://sciencing.com/happens-light-passes-through-prism-8557530.html

I don't know about the internal renderer but most physical engines that supports dispersion and volumetric caustics should be able to create a correct effect without cheating, the last time I've used C4D internal engine I was about 20 years younger so I'm not sure what is supported today. If you want to get a fake effect you will need a directional light to simulate the laser beam, then 3 more colored lights to simulate the dispersion inside the prism, then other 3 lights for the dispersion outside the prism, be aware that due to the internal refraction the light will bend on the prism sides while you made them straight. There is also another option, you can recreate a fake dispersion effect using a mapped plane with a colored gradient, here at 1' 08'' I use this technique for a rainbow but it will probably work for you as well, it's Vray but I'm using C4D shaders so you can do that 100% with the internal engine.

I was having fun with a caustics animation just a few days ago (about 3 minutes a frame on an 8core), done in Vray5 + C4D R25. No fake effects, all physical values and volumetric caustics. I'll post also the animation later, when the laser beam hit the prism at some angle, crazy stuff happens 🙂

Apple offer is quite limited compared to other streaming services, but the ratio of quality vs garbage stuff is much higher compared to the rest (I've Netflix, Prime, Disney+ and other). I do not care that much about dinosaur (my son will though 🙂 ) but there are quite a few nice things right now, Severance, Teheran, Ted Lasso and other. I guess you can take advantage of the free 3 month and see all the best show, than you can disable the subscription since as said the offer is not that vast to justify paying every month (it's cheaper than other services though..).

Looks like a solid update, the new modeling tools look very useful for my workflow.

A very cool feature from the latest build of Vray, you can fix many tiling issues in no time;)

Thanks Igor, didn't notice the video section, I'll post there in the future;)

If anyone is interested I've uploaded a tutorial for creating embroidered fabrics from scratch, the technique is useful also for many other materials and you can use it with every render engine. Hope you'll find it useful;)

4GB is a very small amount of VRAM, the system will already use some of it so realistically you have even less available for render tasks. You can try to use a small model and small textures, if the problem is gone probably is a memory issue when using larger assets and another 4GB card wont help at all. I'm not sure if RS is more memory efficient compared to Octane, you can download the demo and judge by yourself.
