[C4D] General Discussion / Re: Extremely Slow render times

« on: 2022-01-08, 00:20:39 »

With render farms being so cheap,a year or two ago I stopped rendering stuff at home.
Anything that takes longer than 30min I simply send to Rebus and continue working on other stuff.
Even if you have a threadripper at home, it cant match 5, 10 or 20 threadrippers rendering at the same time.

If they're in the same file just animate between cameras with the stage object. Team render sends individual frames for animations, but buckets for stills.

You should be able to do that with the distance shader, use a cube instead of a plane, and then turn on inside color. This should let you mask everything that's inside the cube.

This looks like a gamma mismatch. In after effects or PS try adding an exposure adjustment layer and set the gamma to 0.45 see if that gets you to the right look.

I think you'll need to render this in the VFB not in the viewport, the viewport has a more or less arbitrary aspect ratio.

Open up the "dark" virtual beauty pass in photoshop, add an exposure adjustment layer over it and set the gamma to 2.2.
If it looks like your beauty image, then you have a messed up linear workflow somewhere where the gamma is off.

You'll need to fake it with a gradient.
Go to ikeas website and see their mirrors.

[C4D] Daily Builds / Re: Can i switch off the buckets ? Corona Renderer 7 (Release Candidate 3 )

That's normal, it doesn't have anything to do with corona, 3970x is rated at 3.7GHz.
The boost speed of 4.5GHz only happens when you're using a smaller number of cores, they get a boost, but when all cores are engaged it goes back to its base speed.

First, do you even need glass panes there since they're getting blown out anyway you might as well hide them it's not like they're contributing much to the scene?
If not, you'll need to set up a separate mask for them and then composite the alpha and the windowpane maks to get what you need to replace the background.

As for the highlight burn, you'll probably need to go to corona render settings>frame buffer settings and play with highlight clamping. Search through the corona helpdocs there's an article on how that clamping works vs the camera clamping

What I do to get around this limitation, is to set up the decal with a regular c4d material, adjust the projection and position, and then swap it out with a Corona material once I'm satisfied with the placement.

« on: 2021-05-26, 22:05:45 »

Maybe the same color is plugged in multiple places, so you don't have to change the color value in several places, just one.

[C4D] I need help! / Re: Render times increasing every frame?

« on: 2021-04-14, 10:43:30 »

How sure are you that it's corona slowing down?
This kind of thing has been plaguing Cinema 4D for at least 10 years, usually, it boils down to some generator or sim. Do you have metaball or some kind of sim or dynamics going on?
Some years back I had something similar happen to me, renders started at around 5 min per frame and left it to render overnight, came back to it in the morning to find it still rendering with over 40min per frame now. In my case, it was a metaball causing the issue, and to solve it I simply exported it as an alembic first, so that it doesn't have to calculate every frame.

I've also had a couple of other cases with cloners that were solved in the same way.

When you start a render, where does the extra render time show up, in preparing the scene or in the rendering?

« on: 2021-03-19, 23:47:15 »

I remember having something similar once, I believe it had something to do with the Alpha, I think if straight alfa was turned on it would come out like that in the picture viewer, but don't hold me to it. Multipass was ok though.
You can investigate that as a start if nothing else.

[C4D] I need help! / Re: Product Image on pure white background

« on: 2021-03-06, 10:40:23 »

You can't really get a pure white background straight out of the render, you need to do it the same way as photographers in real life. You get the product well lit and looking right, then in post you adjust the background to pure white.
The good part is that you can set up masks for just about anything in your scene, which makes post that much easier.

[C4D] I need help! / Re: Transparent material not behaving correctly with alpha

« on: 2021-02-19, 16:15:43 »

I've had to do something similar and I ended up just setting up render passes for reflection and refraction in addition to alpha, and then comped everything in After Effects. You can see the end result here.

This was rendered on gray, the blue color and DOF were added in post.
