General CG Discussion / Re: How to select solid background in Adobe Premiere?

« on: 2025-08-14, 16:55:20 »

Thank you for your help; however, I posted the same question in the Adobe Community, and an Adobe employee was able to solve my issue: https://community.adobe.com/t5/premiere-pro-discussions/how-to-select-solid-background-in-adobe-premiere/td-p/15458674#M568722

General CG Discussion / How to select solid background in Adobe Premiere?

« on: 2025-08-13, 13:20:52 »

Hi there!

I rendered an animation in 3ds Max + Corona and, besides the LightMix render, I also ended up with the CMasking_WireColor. My plan is to whiten the background in Premiere, while maintaining a soft shadow. Unfortunately, using the Corona Shadow Catcher Material didn't give me the results I wanted.

Does anybody knows how to select the background color in the CMasking_WireColor, in order to select the Interactive_LightMix background and lighten it up?

Your UI is showing "0 objects included". Open the Include / Exclude dialog, and swap from Include mode to Exclude mode. Right now, your override will only affect objects that are explicitly listed as included in the Include / Exclude list. Swapping to Exclude will mean that "0 objects get excluded" (you will want to check that the "Preserve" options are set to preserve your glass to continue to let light into the scene).

Thank you, that solved my issue!

Hi there!

I'm working on a project and I'm trying the Material Override. However, it simply doesn't work. I closed 3ds Max and reopened it, but the problem remains. What can I do?

Software:
3ds Max 2024
Corona 12 Update 1

Thanks, I'll give those methods a try!

Corona bitmap has transform from object option, you can assign to each HDRI a different object which would you would animate to make that HDRI rotate as you want.

If I understood correctly, I can assign different HDRIs to different cameras, and rotate each HDRI independently (even if is really the same HDRI)?

Hi,

Your lighting setup is too dense, and yes, they cancel each other if placed so.
You can try placing the lights further away from the furniture.

I believe, nevertheless, that a uniformly lit environment light (aka HDRI or a solid color), optionally with some lights, will do the job.

Thank you for your help. I deleted all the lights, added a HDRI and a single plane light above and the results are night and day.

With the addition of a HDRI, a question arises: I needed to rotate the HDRI at the same time I was rotating the camera, in order not to have pronounced shadows. This works for a camera; however, if I want a whole different rotation of the HDRI associated with another camera, what must I do? Is it even possible?

Hi there!

I'm rendering a few animations of some pieces of furniture, and some of the cameras rotate around the subject 360 degrees. Due to this, the lighting needs to be uniform.
However, the concentric arrangment of these lights causes me and issue: they cancel each other and I barely end up with a shadow beneath the furniture.
Is there any way to retain the lights setup and, at the same time, have a defined shadow?

Is it the same in IR and production render? Asking because sometimes such squares may appear in IR since the information about lighting is not re-calculated. It should go away if you run production render or restart IR.

If it happens in both IR and production render, I would suggest sending us the scene at https://support.chaos.com/hc/en-us/requests/new so that we check what might be going on.

Yes, unfortunately I get the same results, even if I restart IR or run a production render.

« on: 2025-06-03, 13:13:29 »

Hi there!

I'm trying to use sheen in order to mimic velvet, but something strange is happening. The square artifacts appear regardless of the roughness of the sheen layer. The objects have correct normals and geometry.
When I disable reflections in the lights parameters, the artifacts become less apparent, but still there.

What's going on?

P.S.: I'm using 3ds Max 2024 and Corona 10 Hotfix 2

[Max] I need help! / How to associate materials from chaos cosmos to corona library?

« on: 2025-05-12, 19:00:37 »

Hi there!

I have a project that was developed in 3ds Max 2024 and Corona 10. Recently, I've had to upgrade to 3ds Max 2025 and Corona 12, and this caused me a problem. Most of my materials were sampled from the Corona Library in Corona 10. However, since Corona Library doesn't exist anymore in Corona 12, all these materials are missing.

Are these old materials from Corona Library still present in Chaos Cosmos? If so, is there a way to automatically associate them to the objects that have the Corona Materials?

It worked. Thank you again for all your help!

I tried with one of my models and it's exactly the solution that I was looking for.

Thank you again for your patience!

P.S.: I modified the material of my object to have a strong color, in order to see if the shadow would inherit the same color. The results were positive; I would like to have my shadows always in shades of grey - is it possible to have those without having to edit the render in Photoshop?

Sorry for haven't had mentioned the Corona version in the first post. I merged the scene and then it worked, thanks.

I was playing with the scene, and the trick works great. However, in my scene I have several lights; should I exclude all of them from casting shadows on the plane, and create a new one just for the shadow?
