[C4D] Daily Builds / Re: Corona for Cinema 4D Beta 1 daily build

« on: 2017-11-15, 09:36:39 »

Having a new problem recently but i'm not even sure how to reproduce it properly so i'm gonna throw that in the wind.
Basically the way it feels, if i work on scene for some time, do a 2k+ render, stop it and start my 5k render overnight, the render crash after a few hours.
Checking at the moment, i only use +/- 80% of my ram overall (64gb). Also it's not constant, i rendered 5k last week without any problem...
It's hard to reproduce because it only happens after a few hours on 4k+ renders and i'm the only one in the company to update with every build (we also have different hardware).
I join the error message i had this morning and the mentioned log, if it's of any help.

Hi guys.

Having a little problem recently (a few weeks i'd say, not sure) and i have no idea if it comes from me... or something else.

Basically as you can see on this simple scene, when i have a "direct" lighting in front my camera i have weird results in my floor reflection :
01 - Back : No problem
02 - Front : No direct lighting on floor
03 - Front with higher glossiness : weird results
04 - Front, no reflection : Direct lighting is back

I'm afraid i can't find a way around this one, client wants this specific view with direct lighting -_-
Any suggestion appreciated !

Notes : i have tried HDRI and sun / sky with similar results.
Edit : tried path tracing, no diffuse, phong tag removal, geometry check, same results.

Hi! Could you provide the scene via our private uploader, so that we can check it out?

Edit: In any case, it seems to me you (or your client) want to hack the way the natural light transport works, so the solution might not be straightforward.

Ok so while cleaning the scene for upload i just tried something and TADA, the problem comes from my background (if i delete it, it works).
I went a bit further and tried a  few things, and while reworking my background material with the traditional approach (ray switch material) it now work with the sun / sky package, but not with the HDRI. I made a clean scene with clear separation between the two lighting packages for testing purpose and just uploaded it ( 1510060018_v3.7z ).
I might be missing something, in wich case i apologise, but so far i don't see what !

Hi,

Not pushing or anything, but do we have an estimation on the next update release ?
We basically have a big animation render coming at the end of next week and and after a lot of test i think that we can't make without a stable team render.
Again, not pushing, just need to start planning a bit and weighting the options :)

Thanks in advance

The camera (or at least its clipping plane) is inside the volumetric object, so volumetrics won't render - move the volumetric object further from the camera.

The Absorption Distance is also too high for the scene, and the color of Absorption and Scattering too dark (very slight changes in either of these colors will make a big difference!) Attaching a modified version of the scene where volumetrics are visible and settings can hopefully be tweaked from there to get the result you are looking for!

Aaaaaaaaaand, there is my elephant. The freakin clipping plane. Not the first time this bad boy drives me crazy >_<
Now i can have fun with my new toy, thank you very much !

Hey, thanks for the inputs.

Sadly, none of it is working and i can't open the max scene here to check the settings. I had some bloom at some point though :)
Anyway, time to end the week soon and renders to start before that, but i join a cleaned version of the scene so anybody can give it a shot and tell me where the damn elephant is hidding.

Thank you very much and good weekend !

[C4D] General Discussion / Need help for Volumetrics

« on: 2017-06-16, 14:00:13 »

Hi,

I've been trying to make volumetrics on Corona for almost a year, first in max, i gave up, now in c4D, and i'm "about" to give up.
Just did everything as in this tutorial :

(Corona Sun + sky, volumetric mat on box with camera outside etc). I tried to change all settings numerous time, and the only result i get are
- a darker, weird scene
- totally black scene
- Normal render.

Feels like the old voodoo magic of vray and drives me totally, totally crazy ; especially when i know that it's probably the elephant in the middle of the room i cannot see -_-
Can't upload the file cause it's an ongoing company project, but i'm open to any suggestion.

Thanks in advance !

Thanks in advance.

Quick update on the procedural Noise Bump :
Still here !

Renders :
Same basic noise, first in Bump (100%), then in Displace (1cm).

I do not know if it has already been mentioned: The noise shader in the bump channel does not look good at all:

> [test B1 noise.jpg] noise shader in bump channel
> [test B1 noise bitmap] the same noise, but as a bitmap
> [test B1 noise displ] noise shader in displace channel

Whether it was so in version A6, I do not know. Since I could not use any noise shader in A6, because Cinema always crashed.

Corona Beta 1 from 2017-04-07

Hi, Allertaler!

I just tried this in beta1 from 2017-04-13 with noise shader, with bitmap (baked noise texture) and Corona bitmap and it looks OK to me. Sure, if you set the strength too high with the noise shader, you're bound to get crazy results, but otherwise, displacement and bump always correspond to each other, not like in your images. Could you maybe ellaborate on what exactly is wrong and if possible, make a scene where we can easily see what you mean? Thanks!

Hi houska,

thank you for your efforts. I tried again with a simple shader ball. The view with a noise shader in the bump channel will not be nicer. I have attached the scene and 2 screenshots.

Same problem here, procedural noise gives me strange results in bump but is fine in displace. Made a couple of renders without reflection on the same scene, but also had the problem on another scene so i don't think it's scene related.

Hi,

Quick update here too, "Render only masks" doesn't work here, it just renders everything even when checked. Tried two basic scenes, same results, but i might be missing something.
Otherwise no problem and fantastic job as usual !

Hi,

First of all thanks for the amazing work ! I worked on Max \ Corona and loved it so much that when i had to switch to C4D \ "He-Who-Must-Not-Be-Named" i was really sad, but this alpha seems already advanced enough for me to convince my boss to let me use it in the production and i can't be thankfull enough !

So i read the road maps \ forums and obviously a lot of things are coming \ planned, but i haven't found \ read anything about a simple tool that my coffee-head could have used this morning.... "Render elements only". Like in "damn i forgot the Mask Render Elements before leaving yesterday" tool. Anything on this ?

Thanks in advance and keep up the good work, can't wait for the beta !
