« on: 2024-08-01, 14:12:48 »

is set up an second, complete inependend file. It also crashes when trying to render...

When I import the non-rendering scene to an existing scene. It renders... strange

[C4D] Bug Reporting / corona crashes when using vertex map

« on: 2024-08-01, 09:41:34 »

Hi all.

Just a little simple scene: a sphere moves through a field driving a vertex-map to change the material of the sphere.

can not get it rendered. It allways crashes after starting rendering.

corona 12
c4d 2024.5.1
win 11

[C4D] I need help! / pasting picked color values

« on: 2024-07-04, 13:42:18 »

Hi all!

Here:

Ciro Sannino shows how to pick color values from pictures the right way in 3ds max. How do I do this in Cinema 4D? There is no corona color shader in c4d, nor I can find a way to set values tu linear. Isnt that possible in c4d? Do I have to use the old vray trick and set the Gamma to 0.454?

Thanks for help

[C4D] I need help! / How to NOT affect the background by tone mapping?

« on: 2024-07-04, 09:28:24 »

For Compositings I use backplate photos or sphericals. How can I use the tone control in the VFB for the 3D objects but ignore the environment? i want the background to be ignored.

Thanks.

3DVista is pretty good. works fine, pretty reliable... Little oldfashined UI.

[C4D] I need help! / Re: Low Rays/s and general slowness

« on: 2024-05-17, 09:14:28 »

I second that.

I also have the feeling that Corona has been getting slower. I dont know since when and I have never used a stopwatch, but the feeling exists indeed.

When rendering stills I do not care about that, but for animations I catch myself accepting higher noise levels to save time.

I remember Vrays main claim with each release was always: SPEEED! . I wish corona would speed up too.

I think, we are talking about rendering the scene with corona and the particles separately in Redshift

[C4D] I need help! / Re: Volumetrics in Physical Material cuts out reflect underneath

« on: 2024-04-18, 07:54:13 »

but do not use displacement für the rabbit hole! ;)

But for this you do not need a rabbit hole. It is pretty simple: Earth diameter is about 12750km, the max height difference on earth between mount everest (+9km) and marianna trench (-11km) is 20km. 20km out of 12750km is about 0,16%. Since you can see the water, maraianna trench is out of equasion. The result is 0,07%.

yes, a cloner works.

I thought there is a more efficient way to render particles faster. Years ago, there was something called "sprites". when you render millions of tiny tiny particles, regular geometry is not needed I think.

Misunderstanding:

Cinema 4d 2024.4 has an brand new particle system. I just want to know how to render, while avoiding real geometry

thank you for that!

But: when it comes to realism, we do not need any displacement or bump oder normal on an earth model. The earth ist perfectly flat. A Billiard ball used for the world cup is allowed to have more displacement oder bump, than the earth in fact has!

Hi all!

Can Corona render the new native c4d Particles or only with the help of real geometry?

thats more or less, what I asked for here:

https://forum.corona-renderer.com/index.php?topic=39660.msg

We need phong restriction for wireshader, AO and curvature shader.

Unfortunately no news for 1 year

[C4D] General Discussion / Re: why is Corona tiles shader restricted to one direction?

« on: 2024-04-05, 12:29:39 »

when I use UVW space, the tile size width and tile size height are not considered.
when I use object space, I can set the dimensions properly.

I have watched the Videos on YT and there is that "feature" mentioned, but I cannot figure out the sense: Either I can map on every side or I can set the dimensions properly. Why not both?

[C4D] General Discussion / why is Corona tiles shader restricted to one direction?

« on: 2024-04-05, 10:22:11 »

Hi all!

Why is the Corona tiles shader restricted to one direction? When I want to place tiles in a corner, I have to assign it twice. Why? Wouldnt it be easier to have it kinda cubemapped?

And: Why is the Corona tiles shader not proper visible in the editor?
