[C4D] General Discussion / Re: AI image enhancer

« Last post by slowgojoe on Today at 08:58:32 »

Hi, this is the same for me. The "Ai enhance" button is grayed out in the vfb even after having added the 'ai enhance' render element, and waiting for the render to finish.

Edit: figured it out - it was the render resolution. I missed the note in the documentation about minimum and maximum render size.

"Note: The width or height of the rendered image for the AI Enhancer to work must be no less than 512px and no more than 2048px."

Not sure what exact shader can be used in C4D, but in Max I would use the Falloff as a mask inside a Mix node.

hahahaaaa... this 3ds max screen shot, not c4d.

[C4D] General Discussion / Texture with UDIM

« Last post by iacdxb on Yesterday at 17:16:32 »

Hi, has anyone tried using UDIM textures in C4D 2025.3?
I tested it with a bitmap and set the UV tiling mode to UDIM, but it doesn’t seem to work. The side texture, which should appear using the second tile, isn’t showing up.
Attaching some screenshots for reference.
Thanks!

[Max] Daily Builds / Re: Toon + Outline Mtl Playground!

Just a quick note, to see if we are on the same page - the directionality for the Corona Light was to give hard shadows from a very large light that was intending to be like an "ambient" light to fill the scene in general. You can get hard banding and hard shadows from a e.g. a sphere light simply by making it very small (and because intensity is measured in light emitted per surface area, increasing the intensity significantly). It's only if you want something large where you have to get into high directionalities for Corona lights.

Though it is just easier in general to use the non-physically realistic Max lights in that case since those actually have zero dimensions and are true point lights :) That's the thing about a Toon result, you don't really want physically realistic lighting in it anyway. You can see that even very small, there is still some slight softening in some edges from a Corona light - which could be beneficial, or not, depending.

Attaching a version of the scene with small Corona light in it, but still, easier and faster to render to use the Max lights, where you also have the option to have shadows or not.

Many thanks, Tom, now it makes sense ;-)

[Max] I need help! / Re: License can't be activated

« Last post by 3dboomerang on Yesterday at 10:18:16 »

Temp fix... I had to uninstall and reinstall my chaos licensing server about 5x in the past 3 Days. Reboot computer >> lost license. Render nodes not working. I see 2x available online whilst only having 1 in reality.  None of both want to activate from the render node, cant get it to accept them. Just bugs out.

I checked the server logs from backburner whilst trying to boot the renders, just "unknown error" and shuts down.

Same for the workstation license.

It's all just not-very well built, is it...

[Max] Bug Reporting / Re: Number Input Occasionally Fails in Post/LightMix

« Last post by Aram Avetisyan on 2025-07-04, 20:59:57 »

Hi,

I have experienced this multiple times already, happening very rarely. As you mentioned, the workaround is either clicking away from VFB, either reopening it.

So far I have come to the realization that this is 3ds Max hotkeys still taking effect in VFB - even numbers on numpad are shortcuts for 3ds Max. I believe I have experienced this same thing in a non-Corona related UI (I think it was PhysicalMtl) too.
I do think this mostly happened after walk mode was used - does this ring a bell for you?

[C4D] I need help! / Re: Tri-planar mapping scale has changed v13 using older files created in v12?

« Last post by edub on 2025-07-04, 18:57:22 »

ok, thanks Maru.  I think I had created this material using a cosmos material as a starting point, and modified some shaders.  I probably don't need the triplanar in this case, but a lot of the cosmos materials are using it, so I can see this being an issue in many cases - or are you saying it's only when combined with the mapping randomizer?  Or was it just a bug in the v12 that was never identified?

I was able to reproduce this issue on my end. I have logged it in our system to be further investigated by our devs.

[Max] Bug Reporting / Re: Aerial perspective produces the wrong result in some situations

« Last post by maru on 2025-07-04, 17:41:48 »

Random idea: create a Corona Volume Mtl and enable Emission in it. Note that LOWER values make it glow stronger. Then assign it to a huge box (or other geometry) below the camera. You may also need to enable some absorption to make it look better. It's just a workaround, but perhaps you could use it?
