[Max] I need help! / Re: Noise patches

« on: Today at 00:50:02 »

Corona uses adaptivity, to prioritize which lights get more calculations in which areas of the image. In this case, your bright sunlight from the other HDRI is leading the way as needing the highest priority as "the most important light" for that area in the image, which results in other lights falling in that area getting less processing.

You could leave everything rendering until that patch clears up for the version where the sun patch is turned off.

Or you make all lights a similar intensity when rendering, e.g. this HDRI could be turned down in intensity so that it is "too dark", that way all lights get equal consideration. It may look odd in the Beauty, or even in single render elemetns, but you then render until the image is clean, and all lights will be equally clean, and you can adjust their intensities in LightMix to boost them back up, and there should be no noisy patches when a bright light source is turned off in LightMix.

Or you can turn off adaptivity, as another approach, forcing Corona to treat all lights equally anyway.

[Max] Feature Requests / Re: Mapping source for CBitmaps

That could be it :) We do now have it as something to be considered for 11, with the enhanced understanding that it is more than just uv tiling that people want to control in one place. Cheers!

Minor fix for a problem with a particular, newer version of Cosmos. We were going to wait for Corona 10, but as more people updated their Cosmos, it became a more immediate problem, so we released the HF. It still wasn't that many affected, and if someone was affected they'd report a problem, and we'd tell them the solution of downloading the HF3. Meantime if no-one is experiencing issues, there was no need for them to update to HF3 with 10 being so close, hence no announcement.

It's more confusion on what functionality people want rather than on what mapping source does - the biggest request that we've seen is to control the tiling in one place, and there is now a solution for that. For controlling things like offset, filtering, etc. we've not noted many requests to be able to do that. We can leave this here for consideration with 11, as it is too late to add it in for 10 :) Meantime folks can tell us how many of y'all want/need/would like controls for those other bitmap parameters.

[Max] Daily Builds / Re: We need your feedback: renaming Corona Maps to CMaps

« on: 2023-06-02, 18:07:29 »

Hi all! We've already decided to revert to the previous, original way of naming. There was a lack of consensus among users on what would work, a general dislike for "CAO", and the 'problem' it solved was pretty minor. Plus it would potentially confuse new users because all our videos and tutorials would not look the same, and it wasn't a major enough change to justify that on top of everything else.

Hey TomG,
scene is attached above =)

Ooops, I didn't spot it nestled between the images - sorry about that, and ty for including it!

TY for reporting, known issue, should be resolved in the next daily (due to code changes to allow importing of IES lights from Cosmos, which are new in Cosmos) PS if you have an important need this functionality, rolling back to the previous daily should resolve it.

We'd need to see a screengrab of your scene setup, to ensure you have set everything up correctly (or the scene itself).

[Max] General Discussion / Re: Corona 1.3 Benchmark

« on: 2023-06-01, 20:02:29 »

The old Corona Benchmark is not intended as a temperature/stress test for a machine, and the rendering code has changed a lot since 1.3 - for example, Denoising was introduced in Corona 1.4, and Denoising is known for taking full advantage of what a CPU can do (and thus, because the CPU is working at its maximum for an extended period, will see higher temperatures). To be honest, poor optimization would likely cause lower temperatures as the renderer will not be able to perform as efficiently, if anything :)

So long as 92 is within the thermal tolerances for your CPU, then there is no problem - and if that is outside the tolerances, it would be wise to check the cooling (is it mounted properly, is the thermal paste properly applied, is it recommended as sufficient cooling for that CPU, etc.)

This is done in Corona 10 for MappingRandomizer, Triplanar, and ColorCorrect via accepting multiple inputs and sending out multiple outputs.

There's no such thing as hotfixes for a daily, just the next daily :)

[C4D] Bug Reporting / Re: Decals, reflection altough 0% gloss

« on: 2023-05-31, 15:35:13 »

Opacity in decal material serves two purposes if Affect is on (which it always was prior to Corona 10):
1) Mixing with the base material
2) Changing base material opacity

This results in opacity 1 being solid, with decal material, and opacity 0 also being solid but with base material, while in between is a blend of both PLUS a change in opacity overall.

To control overall opacity separately, you should set the Mask Source from "Map" (from Shader, in C4D) rather than from the material's Opacity channel. Hope this helps!

[C4D] Bug Reporting / Re: Decals, reflection altough 0% gloss

It's not reflection, it's the opacity - I placed a red cube behind the object, and a blue cube in front of it, and you can see the red cube through it but no reflection of the blue cube.

From what I can see, this is expected - the decal has opacity, it's replacing the opacity of the original plane, so now you can see through the plane based on that opacity.

PS - if you are using Corona 10 daily build, you can disable "Replace Opacity" which I think may be the effect you are looking for.
