Corona Sun moves strictly in a regular circle, deceleration at its zenith (as the client wants). The angle of the sun now cost me only 3 keyframes. Axis rotation - 4 keyframes (due to 180° jump). Seems good 🙂

Like i was saying to you in a precedent post, the deceleration isn't at the zenith but a bit after, and it was more difficult for me. But anyway, i'm done whith that. Thx

Yeah, I forgot you were totally new to C4D, sorry.
In fact, C4D has a really strong obsession with caffein, besides the old COFFEE coding language we have XPresso (kind of a visual coding language), we even have Cappuccino and it's a miracle MAXON did not name the Lathe object Latte ;)

I was totally saying this for the joke about the coffee, but ok, there's really a link, good to know :D

I have search a bit and tried your project, seems reaaally interesting this xpresso thing, i will search for tutorial after my current project. Thanks a lot

Here's a spot I made years ago with the Physical Render Engine. I cringe looking at it now, but I digress. It's a bunch of steps, but after doing the 3D rendering to PNGs and compositing in After Effects, each "screen" panel comes in as a 3D solid layer with corner pin I think. Once you make a new comp based on that layer, you can swap out the contents of that 2D comp and it rotates, masks, etc. in 3D space as you see in the video. This way, I was able to use this as a shell and make 5 more videos with different cars, or even change the client with relatively few clicks. It worked really well once I got it set up. Lots of using the Take system too.

Seems really clean ! Ok i don't know if i'm gonna do like this because my case is a bit different but i note the idea, thanks.

And don't forget to GO BIG ! :D

Hi, you can easily use a light material with an .mp4 video. Click on the animation tab and calculate. Set the frames as desired. Apply to mesh and render. This will only show that it's animated in the final render, it does not work in IR.

Ok thanks, seems hard without the pre-render possibility, you must do it in blind mode but i'm gonna try in few days, i will tell you the result !

It seems you want the developers to redesign the Corona Sun system due to a whim of you and your customer?... :-|
But I took the hint again, ...from Cinemike. I finished school a long time ago and forgot everything, but I searched on Google and applied for C4D Sun Tag: summer solstice time - june 22, N.Latitude - 23.5°, E.Longitude - 45° (picked up experimentally). And I succeeded again. At the same time I have only 5 key frames. The sun does not move in an ideal circle through the equator, but these are features of the inclination of the earth's axis.
Tazok, isn't it easier to listen to the recommendations than to complicate the situation?

No one had been contemptuous until then and I said to myself that everyone was friendly on this forum and that it was nice, but there must always be an ugly duckling.

I will answer you despite your blatant contempt.

I have the right to point out something that seems absurd to me, whether you like it or not.
And you prove me right with your post. You must search on google what is the latitude longitude of the solstice, picked up experimentally, try multiple combinaison, add 5 keys etc.... Just...... for this ?
What's the point ? How much time you lost to do this, when you could do it in 5 seconds and with 2 keys if this angle was infinite.
I think it's not crazy to dare to say that it's a bit shame not to unlock this famous angle.

And i have read every single message, answer to everyone, and learn from every idea here, like i always do and i have said that i was using the technique of TomG and that it was working, but complicated for me because i must put some key smoothing with acceleration deceleration and extra keys complicate everything.
But anyway the job is done now but it was a lot of work and time for really nothing.

I just tell that it's not user friendly and from my newbie C4D point of view but my 15 years of after effects, it's a point that could be change maybe, whether it's realistic or not, and i don't care if you don't like it.
How could you evolve without questioning things sometimes ?

Anyway, I thank all the others for their precious help, their pedagogy, and their patience

So, ALER, isn't it easier to go your way rather than coming talk to me about whims and my clients with contempt ?

Yes, flicker free is necessary, but I thought that was more to prevent the noise from being different per frame and dancing, no? Your animation "feels" like it's reflections from something shiny we can't see. Almost like a caustic effect. Is there a reflective surface or water off camera? Just curious.

There is a glass table not far but i don't think it can react here. No nothing particular, at first sight anyway

This would be "lock sampling pattern" in the performance settings tab.

Ho thanks you're answering my next question without asking it :D

I am sure I did not say that :P
But be it as it may, what you want also happens on an unharmed Earth, twice a year, on locations along the equator on the days of the equinoxes. No  need for space travel, the Sun expression can do that ;)

Still, I'd use one of the above mentioned workarounds if I needed the sun to pass exactly through zenith and nadir. Or I'd put together a little Xpresso setup, if I needed it more than once.

Engage!
Michael "Picard"

Ha yes maybe it was possible to do with a particular location in the world, but pfffiouuu i can't think of all this, too complicated for me haha, I just wanted to put 2 keys and voila ^^'

And i absolutely don't know what is a xpresso setup, maybe something related to coffee, but for a beginner like me (1 week of cinema 4D!), it's too complicated too i think, but maybe soon i'll be aware of those things.
But for now.... gimme a infinite angleeeee powerrr because i'm crying some blood with my key smoothing :PPP

[C4D] I need help! / Re: Sun complete revolution impossible ?? :O

« on: 2023-05-12, 11:26:55 »

and again everything worked out for me, and at the same time, again, I didn’t even sweat :)
(I have the Corona Sun moving through the zenith)

Yes in case the sun movement is linear, there no really prob (even if you must add key to the rotation too and sorry for that but this is stupid, if they unblocked the infinite angle, hop, no more problem), but in my case i must do some kind of acceleration decceleration, but not at the zenith, a bit after, and with the rotation key in the middle of the movement, it's really more hard to configure the key smoothing like i want. Barely impossible (maybe because i'm not used to animated key on cinema 4D but anyway, it's more difficult with this damn rotation key).
Long story short, it's a detail, but I definitely find that it complicates a lot for nothing.

Ah, no, sorry, I really got you completely wrong. I was not aware you needed to animate a scenario when the Earth is no longer rotating around its poles but after a cosmic event is rotating around a new axis that goes somewhere across the equator. My bad ;)

If I follow your logic, we should only create things that happen on Earth? Luckily not, we would be a little bored... ^^'
But ok, Corona is for REALISTIC THING on EARTH. That's all. It's the Judge Dredd realistic LAW and no one can break it ! :D
More seriously, I find that a bit unfortunate to block this function, as if they were telling you "EARTH ONLY WITH CORONA, no divagation! Its a serious render ! We are not on Jupiter or Alpha Centauri!" :D
Sad they don't like to travel into the galaxy :p

You may also want to enable ''flicker free'' in the secondary GI tab. More on that here: https://support.chaos.com/hc/en-us/articles/4528607789585

Ok so it was already in "UHD cache" for the first thing, but it was on "still frame" for the second thing. I have put "animation flicker free" like you said, and seems to be good ! Thanks !

[C4D] I need help! / Animated Texture on a surface

« on: 2023-05-11, 19:20:48 »

Hello !

I need to animate a panel control (like the one on the first screenshot but the temperature gonna up and down etc...) but i don't know really how to do it (the animation of the panel is not a problem, it's just simple motion design, but it's how to apply it in cinema 4D and on my surface properly).

I was thinking of doing the animation in after effects, export it as a high resolution video and use this video like a texture on my surface (The yellow one on the screenshot).

There is a good way for apply a video on a surface ?
(because the only tutorial i found are very old)
Is it a good idea or there is a other way more professional ?

I must do a very close look of the panel, with reflection on it, because it's made of glass (like tactil touch), so it must be very high quality export and render.

Does anyone know the best way to do this please ?

Hi there, perhaps this article may help? https://support.chaos.com/hc/en-us/articles/7777270371473

Also, what are the frames per second? It has a stop motion feel.

It's 25 fps, it's just because i slowed it down a bit on premiere because it was a bit too quick to see, but no problem on that side.

I'm gonna try the "UHD Cache" thing of your link ! Seems very similar to my problem. I'll tell you if it's work.
Thanks for the link !

Hello ! New day, new problem haha !

I did this render but I have this kind of white flicker against the wall.

Someone know what it could be please and what can i do ?

« on: 2023-05-11, 11:23:26 »

I might not quite understand what your problem is (but I think you are making things more complicated for yourself than they actually are), but you DO know that your sun rotation can be bigger than 360°, so you can start anywhere and end whereever you want, without being "blocked" at some point?

In other words: Add 360 or 720 degrees to whatever you need and go from there. More than enough space.

I think i don't understand what your saying neither :D i want more "angle", not rotation, and i can't add nothing to the angle, it's stupidly blocked between -90° and 90°. You can't reach 180, 360 or whatever.

I tried. It's a go, ...and I didn't suffer at all :)
I took the geographical coordinates of the northern (N.Latitude - 64°), 10 may.
In order for the sun to make a full circle (but not ping-pong), the last keyframe was set at 23:59 (instead of 00:00).
If you need a specific shape/slope of the shadows, then you can adjust the coordinates of the Sun/season.

Yes you didn't suffer at all because it's not what i want to do. I need my sun really much higher, and yes it's not "realistic" but i need this for the very precise movement shadow the client asking me. And i can't do it easily because the angle movement is bloqued between -90° and 90°.
I need to do what there is on my first screenshot. Total revolution with very high sun. And it is not easily possible, without adding keys on the rotation too and tricks and whatever.
If the angle was not blocked, i put only 2 keys on it, -90° for the first key and 270° for the second key and voila, job done. But no... because angle is blocked for no reason.

I guess another way would be to use a C4D Infinite light source. It gives you a nice orange line to easily see exactly where your light is aiming at. Might be worth a try. I'd be interested to hear any drawbacks to using a light instead of the sun, as long as you match the color and intensity of course.

In my very quick, 15-pass example, I did not match the angle exactly, but I think it would work. You would have no limits in this technique either. Whatever works for you.

Yes, there is this solution too, but much complicated, keys for the color, the intensity, the movement and whatever because you can forgot the link with the corona sky........
....Whereas if corona sun angle was not blocked between -90° and 90° (so only a 180° angle movement possible), it could be done in 5 seconds !



In short, there are solutions, they complicate everything for nothing when it would be enough to unblock this damn angle ^^'

I have trick with a 180° rotation when i reach the maximum angle and go back after. It's not perfect but it will be fine.

Hi there, have you tried putting a C4D sun tag on it?

I have tried but i can only move the sun with hour and days with that, and i nedd my sun to do a specific mouvement for specific shadows, in precise direction so it's complicated with the sun tag, but maybe i haven't understand something.

Sun tag would be easiest way - other thing is to flip the Rotation from 0 to 180 in one keyframe when sun hits angle of 90, then repeat going from 90 to 0 in angle as now that goes in the opposite direction :)

Yes i have the impression thats' gonna finish like this, but... it's.... so much complicated for nothing !
Why just let us make a simple rotation with the angle, even if it's not perfectly "realistic" in the reel world, i don't care, i need to do this animation... Pfff...

Hi there,
Please consider sun's translation movement is not like a perfect circle, and inclination will depend on the geographical zone you select. This means e.g., if you use the London city geographical coordinates, the Sun will never be at 90 degrees perpendicular to the Earth (I hope I've explained myself, hehe)
So, as @Beanzvision already mentioned, you can use the C4D Sun tag and use real values (geographical, time & date) to animate the night/day cycle.
I hope this helps.
Kind regards.

Yes of course, the "realistic" sun can't do this, but here i don't care about the reel movement, i need my sun to do something specific for specific shadows and i can't do it without cheating with the rotation like TomG said.
It's really complicated for nothing for me. I don't understand why they have blocked this..


Anyway, Thanks all, i'm gonna cheat the sun with 10 keyframes, instead of 2... -_-

Hello !

Completely newbie on corona render (and cinema 4D in same time)
So i must do a animation where the sun do a complete revolution, night, zenith sun and renight.
Seems sooooo simple..... but......... The corona sun can't do a 360° revolution :O !!

How can i do this ? So weird.

When his angle is to -90 it's totally night (zenith night), at 0° it's like dusk, and 90° it's zenith SUN, so totally light, but after you can't continue, it's blocked to 90°, so i can't do a total revolution.
You can only go back, and therefore the shadows don't continue in the right direction, they just... go back...... Lol.
I really don't understand, is it a bug ??
Anyone have a solution please ?

Here's in green what the sun can do, and in red what else i would like to do (a simple revolution.... -_-)
