[C4D] General Discussion / Re: calculate pass

« on: 2024-10-28, 11:56:11 »

No need to rebuid - just turn off the light and use c4d multipass tags instead of corona's compositing ones. Then swap to C4d physical/standard. (Assuming you need masks from various object IDs, it wont work with other passes of couse)

I assume turning off any light bounces would help too?
TBH I've found rendering masks only from corona to be very slow to get a decent result. It may be worth using C4Ds native physical multipass system instead. This will render very clean masks almost instantly.

Well - now I'm really confused. Everything seems back to normal. A mystery where the change originated - but so long as it stays away... all good:)

[C4D] I need help! / Change in behaviour - shader settings

« on: 2024-10-22, 15:53:01 »

Hola.
When loading a bitmap into the texture slot of a material, there were always 3 buttons next to it. I used the Edit Texture & Reload Texture buttons almost constantly in my workflow to edit linked PSD files and make sure they were reloaded afterwards.

Since updating my software, they seem to have been replaced by the enigmatic and much less useful Create Shader and Select Shader buttons.

Does anyone know if the C4D 2025 update did this? Or is an update to Corona 12.

If it's Corona, please change it back :)

Yeah a lot of calculations will take a lot of time unfortunately. Where possible keep the glass as simple as possible (100% gloss, no bump or volumetrics for anything that isnt seen large in the frame). And as suggested above - thin surface on distant objects.

Yeah - shame. I'd love this to work in cinema

I'll assume its not supported then :)

[C4D] I need help! / OSl flakes in C4D corona??

« on: 2024-09-10, 15:23:02 »

Hi - I've been trying to load a OSL shader into the normal slot to make a carpaint flakes type shader....With absolutely no succeess.
Are OSL shaders supported in the c4d version? If so what is the method? I can't find much in the doce...

+1

I guess many are automatically converted from V-ray. But its pretty shoddy IMHO. It wouldn't take that long to check them properly for the Corona versions.

Many less experienced users will leave them as default. Or even use them as 'official' examples of how they should build their own materials. Both are poor outcomes.

[C4D] General Discussion / Re: Cinema 4D + Redshift

« on: 2024-09-10, 12:58:16 »

Has anyone been able to test the latest version of Cinema 4D 2025 with the forced Redshift? Does Corona work well with this version?

By the way, very unfriendly of MAXON to force a function on their users, which not everyone uses but for which they charge extra. I already pay for a rendering plugin (Corona) that suits my needs much better than Redshift, and therefore I will not use it. Give us the choice, just like before, to pay for Redshift or not.

I find this pretty silly TBH. Every single DCC has a built in render engine. That Redshift was NOT the default seeme more unfriendly to me seeing that their leagacy Physical render was so far out of date.

Theres no reason that Corona will be effected beyond the fact that all new releases require a hotfix usually.

[Max] General Discussion / Re: Use full resolution texture preview in Corona

« on: 2024-08-01, 10:53:32 »

Dont want to confuse 'matters - but in C4D there is a dropdown to change the preview resolution in the material dialogue.
This makes it nice and sharp in the viewport.
Perhaps this is a shortcoming of max rather than corona?

Just tried turning the adaptive loght solver off - and it has indeed got rid of those  block artefacts!
Thanks Bengamin for the speedy reply - I though I'd seen a similar problem, but couldn't find it on the forum.

[C4D] I need help! / Help! Blocky artefacts from sunlight

« on: 2024-07-30, 12:56:37 »

I have a scene wih a directional sunlight (physical sun) on a wall. For some reasoin it is causing square artefacts on the wall (see pic).

I have tried changing the wall geo/phong/materials. Plus changing to solver to 4k/path tracing. Plus copying everything into a new file.  Nothing seems to help.

Any ideas?

[C4D] General Discussion / Re: Camera Object Size

« on: 2024-07-19, 09:28:02 »

So Dave, (doll-house? really?)

We are trying to help but you don't seem to be listening. Yes looking at your file the house seems to be about 30cm high - so pretty good scale for a dollshouse!

I did mis-remember the location of the Scene scale dialogue though. it's: edit>configure>scene scale  not file>configure>scene scale

I professionally import from CAD as part of my workflow FYI. Cinema has a pretty decent tools for this

Not a corona issue. Your scene scale is off.
The camera should be roughly proportional to real life, so it looks like the scale of your house is in mm not m. (Unless its supposed to be a dollshouse?
 file>configure>scene scale is where to change it in cinemas menu
