[C4D] General Discussion / Re: Is Corona for cinema 4d Slow because of its alpha stage?

« on: 2015-09-28, 22:00:34 »

I second that question. If I'm not mistaken final 3dsmax alpha releases got some nice render time boosts at the end. Is something similiar planned for c4d version aswell?
Thank you,
matej

@Ondra: great news! Will continue to hang in the office for a while before leaving home so I can try it before the weekend:)

Great work!
I'm really happy that corona for Cinema is at the same quality level as on 3d studio max! You're renders are proving that.
Switching from vray definitely.

Thanks guys!
Nice to hear that Carbon Scatter is the way to go.
I'm downloading the trial right now.
Will get back with feedback.

cheers

If it's really Cinema that can't handle large number of clones than even Carbon Scatter might not help?
I really hope Maxon would tackle the problem in the next version.

@pBarrelas: I like SurfaceSpread too. It has many usefull options with scattering, many of which Mograph doesn't. I mainly use it for grass.

Carbon Scatter is multithreaded? It looks like a good piece of software.
Does anybody have experience with it?

Yes, I could easily make a biger grass patch, but the result isn't as good as having small patches and having control over size and color variations.

Congrats on the images!
I'm trying out Corona on C4d and I have a question if you'd be so kind to help me out.
I have some issues with grass scattering - are you using Mograph or SurfaceSpread for scattering the grass? What's the aproximate precompiling time (preparation time) before the rendering starts? What's the size of your grass patch you're using?
Thanks a lot and many more images like that!

cheers

I've tried rendering without the texture on the blades - I'm afraid preparing time stays the same as before.
I'm attaching the whole scene.

I've checked. CPU usage is around 10-15%. Ram around 8Gb. Which is comparable to vray readings when rendering(precompiling) the same scene.

Hi to all!

I'm starting to test recently published Corona alpha2 for Cinema. I must say I'm really impressed!
Today I was playing around with grass scattering (with surface Spread) and I have a question for anybody that has some experience with it.
It's precompiling really fast when I keep number of render instances low (p.e. when I cover a filed aprox 20meters from camera) but when I try covering aprox 40meters the "Preparing" part goes on and on. I'm asking this because a friend that uses Max + Corona does not seem to experience the same long "Preparing" pre-rendering time. I'm wondering if anybody could light the subject a bit.

I'm attaching a preview image - it only took 2min to render this, which is pretty fast (I'm covering aprox 20m radius around the camera - actually only the cone area). But increasing the size just increases the time really drastically (to about 20min of Preparing time).
Is there anything I can do to speed it up?

The grass patch has 800 polys, it's not that heavy.

I'm using i7 3930K, 32gb ram

cheers,
matej

« on: 2014-10-04, 13:44:58 »

I agree on everything you've sad mp5gosu.
I use HQ PG HDRI images but there is still a need to make small adjustments in gama (somwehere in between 0.75 - 1) in order to get exactlly the right sharpness you want. Even if you use sunny-day HDRI. Offcourse there are alternatives (using sun or direct light) but they are a bit time consuming, but certainly doable.
I don't want to impose my method as the right one, I'm just saying there are HQ 3D artists that use this method and this is why I would love to recreate it in Corona too. I'm a vRay user ATM.
Here's his blog post about the issue: http://bertrand-benoit.com/blog/2010/02/27/on-hdr-lighting/
You could find Peter Gutrhrie's post on his blog too.

@mp5gosu: peter guthrie and berntrand are changing gamma (or is it gain?) for quite some time now, based on their blog reports. So i the rest of the community. So I don't see anything wrong with it, results are great and so is the workflow (no need of positioning the sun to fir the HDR). But I wouldn't change anything besides gamma(gain) though!

@tomislavn: in does work in luminance channel in 1.1 if I'm not mistaken. Will try it out later.

cheers to both!

Are you sure?
I have a simple interior scene and there is no change when I rotate it....hmm.

Another thing: in vRay you would adjust gamma if you'd like sharper shadows when using HDRi. Do you use c4d "Filter" in order to adjust the gamma or do you get sharper shadows in another way? Actually there seems to be a setting in Luminance channel in Corona material .. .but I'm not sure if I should use Luminance channel at all, as some of you suggest ?

thanks
