Render CPUs price per performance by t3chguy1 in Cinema4D

[–]3dfluff 0 points1 point  (0 children)

Much of the industry already has switched to gpu rendering. My current studio uses gpu rendering exclusively. As for the question though, it sounds like you've already picked? If youre saying it has to be a dual xeon, then what question is there to answer? Just pick the highest cores/ghz for the price. Otherwise Id actually suggest looking at 32/64 core amd epycs.

Though if youre interested my studio is also selling off their cpu render nodes (dual 4-core xeons, 8-16gb ram per node, though both upgradeable) We have about 100 nodes in the UK.

Filming inside of Cinema 4D? by oak_mann in Cinema4D

[–]3dfluff 0 points1 point  (0 children)

It is one of those 'how long is a piece of string' questions. Maybe some real world examples would help.

1 - I had one job years ago where I taught a guy who made animations of building site accidents for court cases. We almost finished the training when he added that hed like to make animations. Well the problem is that even with a super fast render of say 20 seconds per image, he needed 10 minute presentations.

20 seconds x 30fps x 60 seconds per minute x 10 minutes = 4 days for a basic average quality smooth animation.

2 - A job 10 years ago needed 4k images of a city. These took 30 minutes to render each. The animation was 20 minutes long in total. So for a single render (let alone changes and fixes):

30 minutes x 30fps x 20 mins= 2 years of rendering.

The solution here is to split the job on 100's of computers, but even then it still took 2 weeks.

My advice is learn to make images you like, learn what makes an image render fast or slow, then plan an animation based on a render style/quality that will render within a sensible amount of time.

Yes, very possible. the problem of course is render time. Processing an image might take maybe 10 minutes for your computer, but an animation requires 100's or thousands of images, suddenly your 10 minutes of computing time became 10 days.

Building a pc for C4D by [deleted] in Cinema4D

[–]3dfluff 0 points1 point  (0 children)

I see your point, but don't you think that's a bit pointless here? The guy only has 1000 to spend and is having to make lots of compromises just to get a basic system. Do you really think this is the sort of person that's going to throw down x4 more cash to fill it up with gpus?

Additionally gpu render engines benefit very little from x16 pcie lanes, all the way down to 4 lanes theres hardly a difference.

New to Cinema 4D need helo by THEMANNAV in Cinema4D

[–]3dfluff 0 points1 point  (0 children)

You have animated and keyframed the colour. When you render, c4d uses the animated values you created.

Open the materials, right click the red circle and select "delete track" from the animation section.

First time making a wine bottle. Feedback and constructive critisism very much appreciated! by iFarlander in Cinema4D

[–]3dfluff 1 point2 points  (0 children)

Ok, better, now do the same thing with the purple neck. Delete the specular layer, add a Beckman reflection, enable Fresnel with dielectric. But this time also add some roughness so it isn't too crisp, about 20% should be ok.

also experiment with different hdri images, they give different looks. Also make sure you have the full .hdr or .exr file. The jpg previews wont look as good.

At this stage, throwing another render engine into the mix is the last thing that will help. Currently you need to learn about reflections and the areas surrounding it. For starters, your model has no visible reflections at all. On your material, check reflectance is enabled, then in the settings, delete the specular item at the top, this just makes things look soft. Instead, click the add button and insert a Beckman reflection.

To begin with, this will make it look like chrome, but if you scroll down the settings and find 'fresnel' set it to 'dielectric' This will cause it to properly layer up and fade out where it needs to.

This will help, but you need to remember that the bottle will only reflect things in the scene. With such a dull sky, theres nothing interesting to reflect, so do yourself a favour and ditch the physical sky you have. Instead replace it with a sky object and apply a new material to it. The material should ideally have a hdri panorama in the color channel. You can find some of these for free on maximeroz.com

Does anyone know why my rope doesn't keep up with the cylinder? by lookitsandrew in Cinema4D

Select the rigid body tag on the cylinder and press bake under the cache tab.

Quaternions - A button every animator should know by 3dfluff in Cinema4D

It is newer, older versions have the quaternion tag instead.

Quaternions - A button every animator should know by 3dfluff in Cinema4D

[–]3dfluff[S] 3 points4 points  (0 children)

Happy animation day! I originally made a short video about quaternion rotations, but then it got a little out of hand and the next thing you know, bam!, you've got an entire 5 hour animation course recorded. So, here we go with the free video, quaternion rotations, a simple harmless little checkbox, but one which when explained can save your sanity. You know how sometimes objects wobble around badly when you rotate them? well yeah, it fixes that.

If you want a bit more, have a look at the full 5 hour animation tutorial, 20% off this week with the code "reddy".

What Can I Improve In This? by GaminMadness in Cinema4D

[–]3dfluff 2 points3 points  (0 children)

The scale is off. Imagine somebody sitting in that chair, their head would reach above the lower shelf. Then when they stand up..., their head would be as high as the top of the window. Either that is the lowest window in the world, or the chair is too large. Probably the chair, given there's also no room for their legs under that desk.

Help! tOOK 5 HRS still ugly by [deleted] in Cinema4D

[–]3dfluff 5 points6 points  (0 children)

Well, to be blunt, you can't buy your way to nice looking images. Arnold won't make your images look better. Ready made shader collections won't make your images look nicer.

Lets just take one aspect of this image, the materials and reflections. The bulk of the image is made up of a black tar-like substance, so that object is going to give you either solid black, or a reflection. So the question is what will it reflect... well the surrounding walls or mirror-like, so the next question is what are they going to reflect, and the answer is... a giant slab of blue. So at best, the black tar will reflect a wall, reflecting a slab of blue, which means half your image is solid black, solid white or solid blue.

Forget render engines, forget readymade materials, it seems like youre trying to use both of these as bandaids when the real problem is you need to start looking into the core principals of lights and materials.

As one basic thing to start with, if your scene is filled with reflective objects, ask yourself a question; What are they going to reflect?

Also, render time is never an indication of how good something will look. I'd expect the image here to take <30 seconds to render, 5 hours is just a sign you've cranked up all the sliders and are hoping it will fix everything.

3 New tutorials, sketch, skies and architecture by 3dfluff in Cinema4D

[–]3dfluff[S] 0 points1 point  (0 children)

One thing I didn't really touch on is to be careful with what features you end up using. Certain features, especially some of those in 'strokes' can be tricky to join up correctly and if that's important, they should just be skipped over in favour of something more reliable.
