[C4D] Bug Reporting / Layered Material - DISPLACEMENT

« on: 2021-11-11, 16:33:58 »

Hello Corona team,

I have a problem with layered material. Each of the material has different displacement texture. The displacement texture from Base material is applied even to the material under the base material which should be masked by black/white texture. Is it a correct behaviour? Am I missing something?

Kind regards

[C4D] Feature Requests / Zoom in material node editor

« on: 2021-09-10, 13:35:57 »

Hello Corona team,

I would like to ask you, if you could enable ZOOM in material node editor at the same way like we can zoom in Cinema viewport - ALT + RMB. It would help a lot to move in the editor. Many thanks.

Kind regards

[C4D] Bug Reporting / Layered Material

« on: 2021-09-10, 10:00:47 »

Hello Corona team,

I have noticed a problem with Layered material. When I copy an object with that material to a different project, the layered material looses all the materials in the Layered material. The materials itself are coppied to a new project, but they are not correctly inserted in the layered material. Please fix this issue. Thanks.

Kind regards

[C4D] Bug Reporting / Light material compositing bug when INCLUDE MODE

« on: 2021-07-21, 18:03:19 »

Hello

I have noticed a bug when using ligting by plane with Light material applied. I use INLUDE/EXLUDE section of the Light material/Emission window to light just some section of my model. EXCLUDE function works fine, but INCLUDE function seems to broken. It ignores it. This needs to be fixed. Many thanks.

Best regards

[C4D] Daily Builds / Invisible objects

« on: 2021-06-28, 08:30:14 »

Hello guys,

I have noticed, that all the objects are invisible as soon as they have applied a material with missing textures. I have moved some textures on my disk to different location so the linked textures in my material were missing. Then all the objects became invisible. I guess it is not a correct beahviour.

Does this happen to other users using Corona and Cinema 19?

[C4D] Feature Requests / Node Material Editor Layout

« on: 2021-06-24, 14:51:29 »

Hello guys

I like to use the node material editor, but it is terribly annoying to always click the right button then a few times the left button to go through the number of subsets to reach forexample the Corona collor correct shader. IT WOULD BE NICE to have all the corona and usable cinema shaders listed on the left side so it could picked directly an placed to the editor. PLEASE TRY TO MANAGE THIS OPTION.

MANY THANKS

[C4D] Daily Builds / Material Library Bug

« on: 2021-06-24, 14:47:50 »

Hello guys

When I use some materials from the library and try to scale the bitmap in the material editor by using the shader LAYER or PROJECTOR it doesn't change anything. Actually it changes the scale in the Cinema perspective window but it doesn't render the scaled bitmap!!!

Please try to fix it. Many thanks.

[C4D] Daily Builds / Node Material Editor Bug

« on: 2021-06-24, 14:45:17 »

Hello

I have noticed a problem with NODE MATERIAL EDITOR. When I edit a material there and delete some branch of bitmap fxp. bitmap for displacement it doesn't actually delete the material in the normal material editor. This can then cause, that the object witrh the material is not rendered.

Please try to fix this. Thanks guys.

[C4D] Bug Reporting / Wierd light color artifacts

« on: 2021-04-30, 17:15:54 »

Hello,

I am having trouble with artifacts showing on a few geometries. It is a bit strange because I have 2 rows of the same chairs in the picture. One seems to be OK but the other one has the artifacts. The same problems shows on more meshes. The meshes are often simple cubes so the geometry shouldn't be the problem. I have tried to place on the chairs simple material without any textures and when I have darken the color the same artifacts has appeared. Any solution?

Thanks guys

[C4D] Bug Reporting / Team Rendering takes more time than one CPU

« on: 2020-11-18, 17:05:35 »

Hello

I am trying to use team rendering for an animation but I am having some problems. First of all when I start rendering the animation in the VFB it works fine. As soon as I render I press TEAM RENDER TO PICTURE VIEWER I get an error about native cinema IES lights which are part of the native Cinema libraries. It is probably because they are not part of the Cinema Client. It is a shame but I can solve it by extracting the IES to another folder and place it back to the scene.

I wanted to render 75-250 frames. It started to calculate 162nd frame. WHY IT DIDN'T START FROM THE BEGINNING?

BUT the biggest problem I got is the TIME RENDERING using the team rendering. On my local machine is AMD Ryzen Threadripper 3960X. On the Client PC are two CPU Xeon E5-2650 v4. I have tested the same scene on both PCs and AMD Ryzen got faster than 2x Xeon about 40% - 50%. So I thought I will get shorter time when I do the team rendering and use all CPUs available. But by doing that I need longer time for one frame with using all CPUs than just with AMD Ryzen. I have checked the status of both machines in the TEAM RENDER MACHINE PANEL and the local machine got orange icon (working) and the Client got green (prepared but not working). When I checked the console it got messages, that the client is working in some passes and chunks. ANY IDEA HOW IS THAT POSSIBLE? This team rendering is really big issue. Especially for animations, when we don't see the progressing preview in the picture viewer like we can see in the VFB while calculating. I really like Corona and I have switched from Octane to that, but when I need to use distributed rendering I am thinking about Octane and how well this part worked there.

Many thanks for any ideas where could be the problem with the time per frame and the other issues.

[C4D] General Discussion / Multilayer PSD with alpha

« on: 2020-11-09, 23:41:14 »

Hello guys

I know I can use shadow catcher material in compositing mode and save an object directly with alpha and shadows emitting by the object. But here is the thing. I would like to save not just the flat image with alpha but all the layers like ID, reflections etc. using multilayer PSD format. THE PROBLEM IS THAT IT DOESN'T SAVE ALPHA in the background and virtual beauty layer. Am I right or am I missing something? Do I have to always save one PSD with layers and one PNG with direct alpha? I know I can save alpha layer itself by selecting it in the multi pass settings and apply it then in Photoshop forexample, but it is sooooooooo cumbersome approach. IS THERE A WAY HOW TO SAVE PSD WITH ALPHA DIRECTLY like you can do it in other render engines? I really do like using Corona but some things can drive people crazy.

[C4D] General Discussion / Distributed rendering

« on: 2020-11-06, 10:09:09 »

Hello

I would like to ask anybody if there is a way how to use the distributed rendering in the interactive VFB mode in Cinema C4D. I can use the team rendering to picture viewer, but it is good just for the final rendering. Obviously it is necessary to use more CPUs while preparing the materials and lights to be enough efficient. I used Octane before and it allowed network rendering almost since the beginning. Maybe it is possible to use DR in Cinema already, but I didn't find any clue how to use it. If somebody knows a solution, please let me know.
If that is still not possible I would like to ask, if there is a certain date/release when DR will bo possible in the interactive mode so I can prepare more complex scenes in Corona without waiting so long for previews. Many thanks for any information.

Best regards

[C4D] General Discussion / SOFT BOX AREA LIGHT

« on: 2020-11-06, 09:57:45 »

Hello

I have found this thread about softbox/texture control of area light a year ago, but it wasn't still change in Corona. It would be really great if we could control the emission of the area light directly in the light settings. I know we can use a simple plane with light material, but it is not as efficient as to control it in the area light directly.
Maybe I am missing something, so if someone knows how to do that, please advice. Thanks

Best regards
