[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.

[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.

Hi all!

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

[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?

[C4D] I need help! / scatter on tiles

« on: 2023-12-21, 08:18:17 »

Hi everyone,

Nate showed in his last YT video how to scatter objects on gaps with the new tile shader. Unfortunately I can't get it to work. Attached you can find the demo scene. Help is very welcome.

Thanks!

[C4D] I need help! / Corona 10 - no material on Cosmos enmesh-patterns

« on: 2023-06-23, 10:35:17 »

H all!

When I use the new enmesh-patterns ans assign materials, the pattern is rendered in white - no materials. Only if I convert the proxy object to mesh I can see the materials.

What can I do?

[C4D] I need help! / How to load opacity from Alphachannel

« on: 2023-05-17, 09:07:55 »

Hi all,

Cinema 4D native material identifies an images alphachannel, when placed in the textureslot in the Alpha-Section of the material.

How can I achieve this in Corona materials? When loading an image with alpha channel (RGBA) into opacity I get the opacity of the RGB not of the A.

Thanks for help!

[C4D] Feature Requests / Normal Maps - which dircection

« on: 2023-03-23, 07:55:49 »

Hi!

There are two ways to interpret normal maps (Y up or Y down) and it is very hard to identify what kind of normal map ons has. You guys always say "flip Y", but this seems not always right.

I there a way to implement something in corona helping finding out what normal map is used?

Hi Team,

it would be nice to have the possibility to restrict the AO- and the wire-shader with the phong-angle.

[C4D] I need help! / Need help creating carbon material

« on: 2022-12-12, 16:35:39 »

Hi all!

I cannot get any good results creating a carbon fiber material.

I tried several map sets from f.e. Textures.com. What I am missing is this depth in the material. My RL sample looks so 3 dimensional, almost like an optical illusion.

I use normal maps, anisotropic rotation and clearcoat layer, but I am not satisfied with any result.

The VRScan carbon material does not work since I have no UVs on my model

Any suggestions?

Hi all.

The Scene converter shows the number of objects to convert (which are lights) but does not convert them to corona lights
